Copyright (C) 2007-2009 Carlo Baldassi carlobaldassi@gmail.com This manual is released under the terms of the GNU General Public License as published by the Free Software Foundation; version 3 dated June, 2007. You should have received a copy of the GNU General Public License along with the library; if not, see http://www.gnu.org/licenses About this document This manual describes in detail the &lqrl; API, starting from a brief overview on seam carving, the internal image representation, a minimal list of basic methods and the full explanation of all the library public methods. In the `examples' directory, you will find a minimal example program, which only uses basic methods, and a full-featured demo program, which uses almost all of the methods described in this document. Both programs are fully commented, see also the README file in the `examples' directory. Refer to the README file for information about installing and compiling. The latest version of the &lqrl; and of this manual can be found at http://liblqr.wikidot.com. Seam carving in brief Basically, the rescaling algorithm tries to find out which parts of the image are important, and which are not, based on the contrast between adjacent pixels; then, the image is resized through the elimination or insertion of continuous paths, called `seams'. The seams connect the top of the image with the bottom when rescaling horizontally, or they connect the left side with the right side when rescaling vertically. In the seam carving process, seams are removed in sequence, therefore shrinking the image by one pixel at a time. The seam insertion process mirrors the seam carving process, introducing interpolated seams in regions where they would have been carved. Once it has been computed, the carving information can be efficiently stored in a so called multi-sized image, which can be used to reproduce the carving operation on the fly at any later moment. It often happens that the automatic feature detection fails to identify as significant some image regions; in these cases a preservation mask can be specified, which marks those regions. In fact, the feature recognition process can be manually driven quite easily to its full extent, by using custom masks. See also the References section for more information about the algorithm. About enlarging As mentioneed above, the enlargment process mirrors the carving process. More precisely, in order to enlarge the image by a given amount of pixels, say N, the library first computes which would be the first N seams to be removed; then, it inserts N new seams nearby those. This means that it is clearly not possible to go beyond twice the original size in a single step. It also means that doubling the image size in this way is just equivalent to standard scaling, since the result is that each seam is just duplicated. For these reasons, the library rescaling engine automatically divides enlarging sessions in steps, and allows to set the step size. This same issue also affects in a tricky way the preservation of image areas when enlarging: suppose your image is 1000 pixels wide, and you have protected an area which is 800 pixels wide. It is then clear that you cannot shrink the image to less than 800 pixels without affecting the preserved area, but the same is true when enlarging, so you should not go beyond 1200 pixels in a single step (= 1000 + (1000 - 800)), i.e. you should use a value lower than 1.2 for the enlargement step size. In general, however, the optimal enlargement step size depends on the image, since large step sizes have the disadvantages discussed above, while small step sizes will tend to inflate the same areas of the image over and over at each step. Overview of the library The &lqrl; is written in C, but can be used into C++ programs without any modification. It has an object-oriented design, so that the terminology in this manual is borrowed from C++. The central class of the library is called &carv_obj;. Carver objects can generate and store multi-size images, or load them, and read them out at the desired size. Internally, multi-size images are stored simply as plain images with the addition of a visibility map. Each pixel in the image has its own visibility level. Whether to display a pixel or not simply depends on the comparison of each pixel's visibility with a given global visibility level. In this way, images of different sizes can be read out, simply by setting a global visibility level. Therefore, once the visibility map has been computed, it allows effortless, real-time scaling. However, visibility maps also necessarily have an orientation, either horizontal or vertical. If we want to resize on the other direction, the visibility map has to be computed afresh, and the previous visibility map becomes useless, because the two maps are not consistent one with the other. This also implies that the resizing order affects the final result: rescaling horizontally first, then vertically, does not yield the same result as following the reverse order. Moreover, one could choose an intermediate way, e.g. by rescaling by one pixel in one direction, one in the other, then iterating as needed to reach the final size. The default behaviour of the library is to rescale horizontally first, then vertically, but this order can be reversed. Visibility maps can be stored in objects of type &vmap_obj;. When an &carv_obj; object is created from an input image, the visibility of each pixel is uninitialised. At this point, one could either import a previously computed &vmap_obj;, or activate the &carv_obj; so that it creates one afresh when asked to. In either case, there's a single method to call, specifiying the new desired size; all the rest will automatically be computed as necessary. By default, the visibility maps are only computed up to the extent to which they are needed for resizing. Basic methods Following is a list of the basic public methods associated with the &carv_obj; objects: constructors and destructor LqrCarver * lqr_carver_new (guchar *buffer, gint width, gint height, gint channels); LqrCarver * lqr_carver_new_ext (void *buffer, gint width, gint height, gint channels, LqrColDepth colour_depth); void lqr_carver_destroy (LqrCarver *carver); initialization LqrRetVal lqr_carver_init (LqrCarver *carver, gint delta_x, gfloat rigidity); image manipulations LqrRetVal lqr_carver_resize (LqrCarver *carver, gint new_width, gint new_width); LqrRetVal lqr_carver_flatten (LqrCarver *carver); readout gboolean lqr_carver_scan (LqrCarver *carver, gint *x, gint *y, guchar **rgb); gboolean lqr_carver_scan_ext (LqrCarver *carver, gint *x, gint *y, void **rgb); gboolean lqr_carver_scan_by_row (LqrCarver *carver); gboolean lqr_carver_scan_line (LqrCarver *carver, gint *n, guchar **rgb); gboolean lqr_carver_scan_line_ext (LqrCarver *carver, gint *n, void **rgb); get values gint lqr_carver_get_width (LqrCarver *carver); gint lqr_carver_get_height (LqrCarver *carver); gint lqr_carver_get_channels (LqrCarver *carver); LqrColDepth lqr_carver_get_col_depth (LqrCarver *carver); The fastest way to see how they work is having a look at the code of examples/liquidrescale-basic.cpp, which is a very simple and fully commented demostrative program. The return value of many functions is of type LqrRetVal. This is just an enum type which can be used for signal handling, see the Signal handling section. The other classes are optional: the class &vmap_obj; is used to hold the carving information (and the class &vmapl_obj; is used to retrieve it from the &carv_obj; ojects); the class &prog_obj; is used to customize progress report from the resizing engine (by default it is turned off). A complete list of the library public methods can be found in the reference at the end of this document. LqR library API user manual Signal handling Many library functions return a value of type LqrRetVal. This is an enum type which can hold the values: &err_ok; everyting OK &err_err; generic fatal error &err_nomem; not enough memory &err_cancel; action cancelled by the user At top level, it is important that the user handle these values explicitly, because the library functions don't do anything else than stopping and returning an error signal in case of errors. An easy way is setting up some macros and wrap each function call with those, as shown in the example files. Below top level, the library provides some convenient macros which can be used to wrap function calls, in order to propagate these signals: LQR_CATCH (expr) if expr is equal to &err_ok; it does nothing, otherwise it returns expr (or the result of the execution of expr if it happens to be a function) LQR_CATCH_F (expr) returns &err_err; if expr is FALSE LQR_CATCH_MEM (expr) returns &err_nomem; if expr is NULL The names of these macros have changed since version 0.4; the previous names CATCH, CATCH_F and CATCH_MEM are still available, but they can be disabled at configure time if they cause conflicts (configure --help for details). Generating the multi-size image Carver object creation The &carv_obj; objects are initialised from a plain buffer representing an image. The default constructor assumes a colour depth of 8 bits per channel: LqrCarver * lqr_carver_new guchar * buffer gint width gint height gint channels Here, buffer is the array representing an image of size width by height with channels colour channels per pixels. Thus, the overall buffer size has to be of widht * height * channels unsigned characters, and ordered such that the k-th colour of the pixel at row y and column x is found at: buffer[(y * width + x) * channels + k] (this assumes that x, y and k all start from 0 and reach the maximum values widht-1, height-1 and channels-1, respectively) The function returns a pointer to the newly allocated &carv_obj; upon success, or NULL in case of insufficient memory. In order to create &carv_obj; objects with more than 8 bits per channel, an extended version of the constructor must be used: LqrCarver * lqr_carver_new_ext void * buffer gint width gint height gint channels LqrColDepth colour_depth The differnece with the default version is that the input buffer must be passed as void, and its type must be specified through the additional parameter colour_depth, which can take one of the following values: &col_depth_8i; 8 bit unsigned integers (guchar) &col_depth_16i; 16 bit unsigned integers (guint16) &col_depth_32f; 32 bit floating point (gfloat) &col_depth_64f; 64 bit floating point (gdouble) Floating point type values must range between 0 and 1. The library has some support for different image types and color models. When a &carv_obj; object is created, the image type is automatically set from the number of channels (basically, assuming that the image is either grayscale or RGB with possibly an alpha channel), but it is important to set it manually using the function lqr_carver_set_image_type if your program has to deal with different color models. See the section Choosing the image type for more details. By default, the buffer is assumed to be a copy of the original image, and therefore it is owned by the &carv_obj; object and must not be accessed directly any more (and of course it must not be freed, the &carv_obj; destructor does it). If, instead, you want the &lqrl; to keep the buffer intact, you must flag the &carv_obj; after creation (or after activation), using this function: void lqr_carver_set_preserve_input_image LqrCarver * carver This function must be used before any other operation takes place. Carver activation The newly created &carv_obj; consists only of the image buffer plus an uninitialised visibility map. If one had a previously computed visibility map, it could be imported into the &carv_obj; and that would be enough (see the Importing a visibility map in a carver section). If the visibility map has to be computed, the &carv_obj; needs to be initialised through this function: LqrRetVal lqr_carver_init LqrCarver * carver gint delta_x gfloat rigidity Here, delta_x is the maximum allowed transversal step of the seams (0 means straight seams, the typical value is 1), while the rigidity parameter can be used to introduce a global bias for non-straight seams (the typical value is 0; a nonzero value can be modulated locally for specific areas using the functions described in section Adding a rigidity mask). It is currently an error to initalise a carver object if a visibility map has been imported already. Choosing the image type The library supports a small number of different image types/color models in order to correctly compute quantities such as the brightness of a pixel, which are important for automatic feature detection. The image type can be set manually using the function: LqrRetVal lqr_carver_set_image_type LqrCarver * carver LqrImageType image_type The type LqrImageType is an enum which can take these values: &img_type_grey; &img_type_greya; &img_type_rgb; &img_type_rgba; &img_type_cmy; &img_type_cmyk; &img_type_cmyka; &img_type_custom; When creating a &carv_obj; object, the image type is inferred from the number of channels according to this table: Image types assigned by default channels type 1 &img_type_grey; 2 &img_type_greya; 3 &img_type_rgb; 4 &img_type_rgba; 5 &img_type_cmyka; >5 &img_type_custom;
When setting a carver to &img_type_custom;, it is assumed that there are no alpha or black channels, but if there are, their index can be specified with the functions: LqrRetVal lqr_carver_set_alpha_channel LqrCarver * carver gint channel_index LqrRetVal lqr_carver_set_black_channel LqrCarver * carver gint channel_index Use the value -1 in the indices arguments to unset those channels. Note that using &img_type_custom; in a carver normally requires special care in the choice and definitions of the energy functions (see the Automatic feature detection section). Setting manually the alpha or black channel with the above functions automatically sets the carver image type to &img_type_custom;. The support for CMY (and derived) color models is very naïve, since no color profiles are yet managed by the library. Liquid rescaling The resizing method Once initialised, or if a visibility map has been loaded, the image can be resized through this function: LqrRetVal lqr_carver_resize LqrCarver * carver gint new_width gint new_height This function decides automatically whether it can use the already computed visibility map, it has to update it or waste it completely and start afresh. This last event occurs when the map was computed for horizontal resizing and a vertical resize has been requested, or vice versa, and also when the required enlargment is bigger than the enlargement step value (see Setting the enlargement step). Note that only initialised carvers can update or change the visibility map; if this is not the case, an error is returned. The function also takes advantage of the fact that the enlargment process mirrors the shrink process. For example, if the original size of the image is (w0, h0) and lqr_carver_resize is invoked with (w0 - 100, h0) as an argument, then subsequent calls to the function will allow on-the-fly resizing in the whole range from (w0 - 100, h0) to (w0 + 100, h0). (But note that this may be overcome if w0 + 100 is bigger than the enlargement step.) Flattening In order to resize in more than one step, the image can be flattened in its current state, thrugh this function: gboolean lqr_carver_flatten LqrCarver * carver The return value is &ret_false; in case of insufficient memory, &ret_true; otherwise. This function destroys the current visibility map and reinitialises the multi-size image from its current state. Every time that the image is flattened (including when changing the resize direction) the original image and all information about it is lost. Cancelling an action The resizing and flattening operations can be aborted using this function: LqrRetVal lqr_carver_cancel LqrCarver * carver This function can be invoked asynchronously, from a different thread with respect to the one in which the resizing or flattening methods were called. If successful, this function will return &err_ok;, and any ongoing resizing or flattening functions will immidiately abort and return the special value &err_cancel;; however, this function will have no effect if no operation was in progress when calling it. This function can be called multiple times. Whenever a function returns &err_cancel;, it means that the &carv_obj; object is in an inconsistent state, and there is currently no way to recover from this situation. Therefore, any further operation on it must be avoided, and it must be destroyed. The functions lqr_carver_resize and lqr_carver_flatten are not the only ones which can return &err_cancel;; instead, any function in the library whose return type is LqrRetVal and which operates on &carv_obj; objects can return such value: for example, any function will do so if called over a &carv_obj; object for which an operation was actually cancelled (but this is not the only possibility). Reading the multi-size image Pixel by pixel Once you have rescaled the image, you can read out the result through the functions: gboolean lqr_carver_scan LqrCarver * carver gint* x gint* y guchar** rgb or gboolean lqr_carver_scan_ext LqrCarver * carver gint* x gint* y void** rgb Here, x and y are pointers to the varaibles which will hold the pixel coordinate, while rgb is a pointer to an array which will contain the pixel colour information. If the carver was created using the standard 8-bit constructor lqr_carver_new, the first form can be used, otherwise you must use the extended form lqr_carver_scan_ext. In this last case, the output pointer rgb must be passed as a pointer to void*, but the outcome should actually be cast to a pointer to an array of the appropriate type, depending on the &carv_obj; colour depth. The return value is &ret_false; when the end of the image is reached, or the buffer has the wrong number of bits, &ret_true; otherwise. Each time these functions are invoked, they will store the coordinates and rgb information in the output pointers and move to the next pixel. If they reach the end, they reset the reader and return &ret_false;. Here is a sample code usage: A simple readout example gint x, y; guchar *rgb; while (lqr_carver_scan (carver, &x, &y, &rgb) { my_plot (x, y, rgb[0], rgb[1], rgb[2]); } In this example, it is assumed that the image has three 8-bit colour channels, and that there exist some function my_plot which writes out the pixels somewhere. The same readout example with different colour depth would read like this: A simple readout example - extended version gint x, y; void *rgb; gdouble *rgb_out; while (lqr_carver_scan (carver, &x, &y, &rgb) { rgb_out = (gdouble*) rgb; my_plot (x, y, rgb_out[0], rgb_out[1], rgb_out[2]); } In this example it is assumed that the carver was loaded with the &col_depth_64f; as the colour_depth argument in the constructor lqr_carver_new_ext, and that it has 3 colour channels (see the constructor section for details); therefore, the output is cast to type gdouble before using it. The rgb array is owned by to the carver object, so it doesn't need initialization, as in the example. Indeed, it must be used for read-only purposes, and the content should always be copyed after each call to a scan function. One line at a time The image can also be read one line at a time, but it is not possible to freely decide if it is to be read by row or by column. Instead, this has to be queried by calling this function: gboolean lqr_carver_scan_by_row LqrCarver* carver The function returns &ret_true; if the image is read by row, and &ret_false; if it is read by column. Then, the image can be read through these functions: gboolean lqr_carver_scan_line LqrCarver* carver gint* n guchar** rgb or gboolean lqr_carver_scan_line_ext LqrCarver* carver gint* n void** rgb These functions work exactly the same way as lqr_carver_scan and lqr_carver_scan_ext, but only one coordinate is stored (either the row or the column number), and the rgb array will contain a whole line. Here is a sample code usage for the standard 8-bit case: Line-by-line readout example gint n; guchar *rgb; gboolean by_row; by_row = lqr_carver_scan_by_row (carver); while (lqr_carver_scan_line (carver, &n, &rgb) { by_row ? my_plot_row (n, rgb) : my_plot_col (n, rgb); } where, as before, it is assumed that the my_plot_row and my_plot_col functions have been previously defined and "know what to do". The extended version for images with more colour depth is very similar, it only requires an additional cast: Line-by-line readout example - extended version gint n; void *rgb; guchar *rgb_out; gboolean by_row; by_row = lqr_carver_scan_by_row (carver); while (lqr_carver_scan_line_ext (carver, &n, &rgb) { rgb_out = (gboolean*) rgb; by_row ? my_plot_row (n, rgb_out) : my_plot_col (n, rgb_out); } Resetting Normally, it is not needed to reset the image scan. However, if the scan has been stopped at same intermediate step for some reason, the following function can be used to restart from the beginning: void lqr_carver_scan_reset LqrCarver* carver Automatic feature detection Foreword The automatic feature detection relies on the evaluation of the relevance of each pixel; this quantity is called `energy': the higher the energy of a pixel, the less likely it will be that such pixel will be directly involved in the rescaling. The energy function which the library uses can be customised; normally, edge detector filters are the best choices for this purpose. There is a unified framework in the &lqrl; for energy fucntions: briefly, each energy function used by the library receives the current position and image size as parameters, and is provided access to a square of values from the image, centered around the current position. This access is provided through an object which is called a "reading window", and the image pixels are not read directly, but rather they are accessed according to a "reader type", which means that the energy function can get e.g. the brightness of a pixel without needing to care for the underlying image representation, i.e. the image type or the colour depth. The library provides a small set of very simple (yet normally effective) gradient-based energy functions, and a customisation framework for defining more functions. Builtin energy functions The library has some builtin functions for energy evaluation; in order to set one of the builtin functions in a &carv_obj; object this function is used: LqrRetVal lqr_carver_set_energy_function_builtin LqrCarver* carver LqrEnergyFunctionBuiltinType ef_ind The currently available builtin functions which can be used as ef_ind are: LQR_EF_GRAD_XABS absolute value of the brightness gradient in the direction of the rescaling (this is the default) LQR_EF_GRAD_SUMABS sum of absolute values of the brightness gradients in both directions LQR_EF_GRAD_NORM norm of the brightness gradient LQR_EF_LUMA_GRAD_XABS absolute value of the luma gradient in the direction of the rescaling LQR_EF_LUMA_GRAD_SUMABS sum of absolute values of the luma gradients in both directions LQR_EF_LUMA_GRAD_NORM norm of the luma gradient LQR_EF_NULL null All of the above gradient functions have a radius of 1 pixel. Custom energy functions Custom energy functions for a &carv_obj; object are set using this function: LqrRetVal lqr_carver_set_energy_function LqrCarver* carver LqrEnergyFunc ef_func gint radius LqrEnergyReaderType reader_type gpointer extra_data Here, ef_func is the function (the prototype will be explained below), radius is used to set the size of the square region around each pixel which is used to evaluate the energy for that pixel, reader_type is used to set which quantity is used for the energy computation (e.g. brightness, luma etc.) and extra_data is a (void) pointer which can be used to pass additional parameters to the energy function. The LqrEnergyReaderType is an enum which can take these values (also noted is the number of channels of the corresponging output): LQR_ER_BRIGHTNESS brightness (1 channel) LQR_ER_LUMA luma (1 channel) LQR_ER_RGBA RGBA (4 channels) LQR_ER_CUSTOM read the normalised image channels as they are (as many channels as the image has) These readouts always return values beetween 0 and 1. Note that these readouts may have special meanings depending on the image type: for LQR_GREY_IMAGE, LQR_GREYA_IMAGE and LQR_CUSTOM_IMAGE images, the LQR_ER_LUMA readout will yield the same result as LQR_ER_BRIGHTNESS for LQR_CUSTOM_IMAGE images, the LQR_ER_BRIGHTNESS readout will return the average pixel value (additive, i.e. if a black channel is present the channel values will be inverted and multiplied by the black channel inverse), multiplied by the alpha channel value. for LQR_CUSTOM_IMAGE images, the LQR_ER_RGBA readout cannot be used: it will always return 0 The custom energy function must be declared like in the following sample declaration: Custom energy declaration gfloat my_energy (gint x, gint y, gint width, gint height, LqrReadingWindow *rwindow, gpointer extra_data); This function should return the energy at pixel x, y, based on the knowledge of the current image size (obtained from width and height) and the content of the image in a square around that pixel, which is passed through the rwindow reading window: in order to access this content, this function must be used: gdouble lqr_rwindow_read LqrReadingWindow * rwindow gint x gint y channel channel When reading out the content from a window, the x and y parameters are relative to the window centre (which instead is given by the x, y parameters passed to the custom energy function), and they both range between -radius and radius included (radius being the same one which is used in lqr_carver_set_energy_function). The parameter channel specifies which channel to read out; depending on the read_type passed to lqr_carver_set_energy_function the range and meaning of this parameter will change: for the cases LQR_ER_BRIGHTNESS and LQR_ER_LUMA it must be 0, because the readout consists of a single channel, for LQR_ER_RGBA it must be between 0 and 3 (and then the readout will contain the RGBA information), while for LQR_ER_CUSTOM it must be one of the original image channels. The rwindow parameters can be read out from within a custom defined energy function using these functions: LqrEnergyReaderType lqr_rwindow_get_read_t LqrReadingWindow * rwindow gint lqr_rwindow_get_radius LqrReadingWindow * rwindow gint lqr_rwindow_get_channels LqrReadingWindow * rwindow Following is an example of how a simple Sobel fliter can be defined and used within this framework: Custom energy definition and setup /* definition */ gfloat sobel(gint x, gint y, gint width, gint height, LqrReadingWindow *rw, gpointer extra_data) { gint i, j; gdouble ex = 0; gdouble ey = 0; gdouble k[3][3] = {{0.125, 0.25, 0.125}, {0, 0, 0}, {-0.125, -0.25, -0.125}}; for (i = -1; i <=1; i++) { for (j = -1; j <=1; j++) { ex += k[i + 1][j + 1] * lqr_rwindow_read(rw, i, j, 0); ey += k[j + 1][i + 1] * lqr_rwindow_read(rw, i, j, 0); } } return (gfloat) sqrt(ex * ex + ey * ey); } /* usage */ lqr_carver_set_energy_function (carver, sobel, 1, LQR_ER_BRIGHTNESS, NULL); In the above sobel function it is assumed that the radius is 1 and that the readout will consist of a single channel. Furthermore, no boundary checking is performed, and therefore the parameters ¶m_x;, ¶m_y;, ¶m_w; and ¶m_h; are not used. Also, no extra parameters are passed to the function. The function lqr_rwindow_read returns 0 when the requested value is out of the image boundary or beyond the reading window radius. The energy functions are called over the transposed image in case of vertical scaling, therefore, if they are asymmetrical, the result will be different depending on the scaling orientation (this is the case for example for the LQR_EF_GRAD_XABS builtin function). The energy function output should be normalised in order to be comparable with the builtin functions, otherwise the scale of the bias would be different depending on the energy function used. This is the reason why in the Sobel filter written above the kernel k is scaled so that the sum of the absolute values of the matrix is equal to 1. In actual code, the call to lqr_carver_set_energy_function should be protected to test its return value. Reading out the energy The energy can be read out with three similar functions, all of which fill a buffer provided by the user, but in different ways: two of them are suitable for plotting, while the third one can be used to retreive the true values of the energy, as used internally. The first function can be used to get a buffer of normalised values, and it has a simple syntax: LqrRetVal lqr_carver_get_energy LqrCarver * carver gfloat * buffer gint orientation This function writes the the energy values at the time of calling to the given buffer, ordered by row and then by column. All values range between 0 and 1. The buffer must be allocated by the user before calling it. The orientation parameter determines which orientation will be used when computing the energy: 0 means horizontal, 1 means vertical. The carver need not be initialised; if a bias was added to it (see the Adding a bias section), its effect is included in the output. The above function does not return the true energy which is used internally, because that would not be suitable for plotting, since the energy range is arbitrary (only the energy differences are meaningful, and there is no upper nor lower bound to the values). In order to get the true energy values used internally, this function must be used instead (with the same syntax): LqrRetVal lqr_carver_get_true_energy LqrCarver * carver gfloat * buffer gint orientation The last function can be used to fill directly an image buffer: LqrRetVal lqr_carver_get_energy_image LqrCarver * carver void * buffer gint orientation LqrColDepth col_depth LqrImageType image_type In this case, the buffer must be passed as void*, while the col_depth and image_type are used to specify the colour depth and the image type, in the same way as is done when creating an &carv_obj; object (see Carver objcet creation and the Choosing the image type sections). The only restriction is that it is not possible to ask for &img_type_custom; image types. For any choice of the parameters, the buffer will hold a greyscale image, ranging from black (lowest energy) to white (highest energy). The opacity (alpha) will be set to 1, if present. All the information will be stored in the black channel in &img_type_cmyk; and &img_type_cmyka; image types. Calling the function lqr_carver_get_energy_image with &col_depth_32f; and &img_type_grey; arguments will yield the same result as calling the function lqr_carver_get_image, but the latter is slightly more efficient. Adding a bias Foreword The automatic feature detection can be driven manually by adding a bias to the pixels of the image. For example, it is possible to protect regions of the image by adding a positive bias to the corresponding pixels. This will make the seams more unlikely to cross those regions, thus avoiding distortion (but increasing distortion of the other regions). It is also possible to make the seams more likely to cross some regions by adding a negative bias to them. In this case, reducing the size of the image will tend to erase those regions, while (possibly) keeping the rest of the image in a consistent state. The bias has to be added before the resizing takes place (but it can be added before initialisation since version 0.4). In all of the bias-related functions, the bias is added on top of the existing one, so that all of the functions can be called multiple times. Adding a bias pixel by pixel The function to use in order to add a bias to a given pixel is: LqrRetVal lqr_carver_bias_add_xy LqrCarver* carver gdouble bias gint x gint y Typical values for the bias parameter would be between 100 and 10000 in module. Using an array of floating-point values It is possible to use a whole array of floating points at once through this function: LqrRetVal lqr_carver_bias_add LqrCarver* carver gdouble* buffer gint bias_factor Here, buffer is an array contining the bias values, and it is assumed to have the same size as the image loaded in carver, while bias_factor is an overall bias factor, which can be used to affect the global bias level: if the elements of buffer are of order 1, a standard choice for the bias_factor would be between 100 and 10000 (in module). This function, and all the following, will not swallow the buffer (to the contrary of what happens e.g. when creating a new &carv_obj; object and allowing the default behaviour), therefore the buffer must be freed by the user afterwards. Using another image The bias can also be read from an 8-bit rgb buffer. This buffer has to be in the same format as the one used in the 8-bit LqrCarver constructor (but may have a different number of colours per channel). The function is: LqrRetVal lqr_carver_bias_add_rgb LqrCarver* carver guchar* buffer gint bias_factor gint channels As in the previous case, buffer is assumed to hold and image of the same size as the one in the carver. The buffer contents will be transformed into floating-points by averaging the colour components and multiplying the result by the alpha channel (transparency) value. The existence of an alpha channel is inferred from the channels value: if this is 1 or 3, no alpha channel is assumed, if it is 2 or 4 or greater, it is assumed that the last channel holds the alpha value. If this is not what you want, you should resort to one of the previous methods. Operating on a specific area The two previously described functions operate on the whole &carv_obj; image. It is also possible to access specific image regions in a similar way; for the floating point case use: LqrRetVal lqr_carver_bias_add_area LqrCarver* carver gdouble* buffer gint bias_factor gint width gint height gint x_off gint y_off while for the rgb image case use: LqrRetVal lqr_carver_bias_add_rgb_area LqrCarver* carver guchar* buffer gint bias_factor gint channels gint width gint height gint x_off gint y_off In both functions, ¶m_w; and ¶m_h; are used to specify the size of the area of interest, while x_off and y_off specify its offset. For the rest, both functions work in the same way as their global couterpart. The provided buffers have to be of size ¶m_w; * ¶m_h; (or ¶m_w; * ¶m_h; * ¶m_channels; for the rgb case) but the specified areas need not to be strictly included inside the &carv_obj; image area : only the parts which overlap with it will be used. For example, the offsets can also be negative. Adding a rigidity mask Foreword The rigidity parameter which is set at carver activation time (see section Carver activation) normally affects the whole image. It is possible, however, to specify which areas of the image should be affected by using a rigidity mask. When a rigidity mask is used, each pixel of the image acquires an individual rigidity coefficient, which has to be multiplied with the overall rigidity parameter to get the actual pixel's rigidity. This is useful in some situations to reduce distorsions in specific areas of the image while keeping the seams optimal in other areas. The library interface to deal with rigidity masks follows very closely the scheme for bias masks as described in the bias section, the main difference being that no equivalent to the bias factor has to be provided (since it is already given in the lqr_carver_init function). The rigidity mask has to be added always after the &carv_obj; initialization and before resizing takes place. (Note that this is different from the bias, which instead can also be added to non-initialised carver objects.) Whenever a rigidity mask is set, all pixels for which the value is not explicitly defined will have coefficient 0, i.e. the rigidity setting will will be disabled. All of the functions can be called multiple times, but their effect is not summed up, to the contrary of what happens for the bias functions; instead, new values will substitute old ones when the affected regions overlap. Adding an individual rigidity coefficient to a pixel The function to use in order to set the rigidity mask at a given pixel is: LqrRetVal lqr_carver_rigmask_add_xy LqrCarver* carver gdouble rigidity gint x gint y Using an array of floating-point values It is possible to use a whole array of floating points at once through this function: LqrRetVal lqr_carver_rigmask_add LqrCarver* carver gdouble* buffer Here, buffer is an array contining the rigidity coefficients values, and it is assumed to have the same size as the image loaded in carver. This function, and all the following, will not swallow the buffer (to the contrary of what happens e.g. when creating a new &carv_obj; object and allowing the default behaviour), therefore the buffer must be freed by the user afterwards. Using another image The rigidity mask can also be read from an 8-bit rgb buffer. This buffer has to be in the same format as the one used in the 8-bit LqrCarver constructor (but may have a different number of colours per channel). The function is: LqrRetVal lqr_carver_rigmask_add_rgb LqrCarver* carver guchar* buffer gint channels As in the previous case, buffer is assumed to hold and image of the same size as the one in the carver. The buffer contents will be transformed into floating-points by averaging the colour components and multiplying the result by the alpha channel (transparency) value. The existence of an alpha channel is inferred from the channels value: if this is 1 or 3, no alpha channel is assumed, if it is 2 or 4, it is assumed that the last channel is holds the alpha value. If this is not what you want, you should resort to one of the previous methods. Operating on a specific area The two previously described functions operate on the whole &carv_obj; image. It is also possible to access specific image regions in a similar way; for the floating point use: LqrRetVal lqr_carver_rigmask_add_area LqrCarver* carver gdouble* buffer gint width gint height gint x_off gint y_off while for the rgb image use: LqrRetVal lqr_carver_rigmask_add_rgb_area LqrCarver* carver guchar* buffer gint channels gint width gint height gint x_off gint y_off In both functions, ¶m_w; and ¶m_h; are used to specify the size of the area of interest, while x_off and y_off specify its offset. For the rest, both functions work in the same way as their global couterpart. The provided buffers have to be of size ¶m_w; * ¶m_h; (or ¶m_w; * ¶m_h; * ¶m_channels; for the rgb case) but the specified areas need not to be strictly included inside the &carv_obj; image area : only the parts which overlap with it will be used. For example, the offsets can also be negative. Tuning The behaviour can be tuned through some additional functions. Setting the enlargement step As mentioned in About enlarging, if the requested final size is too big, the rescaling is automatically divided in steps. For example, let us suppose that we have created an &carv_obj; object from a 100 by 100 pixels image, and that we call lqr_carver_resize with 600 and 100 as width and height arguments. With the default settings, the rescaling of the width will be performed in 3 steps: first, from 100 to 199, then from 199 to 397, and finally from 397 to 600. The rule here is that the maximum size which can be reached in a single step is equal to twice the original size minus one, and that at each step the original size is reset to the current size (through an internal call to lqr_carver_flatten). In most situations, however, the steps should be smaller in order to obtain good results. This can be set with this function: LqrRetVal lqr_carver_set_enl_step LqrCarver * carver gfloat enl_step The value of enl_step must be strictly grater then 1.0 and less then (or equal to) 2.0. The default value is 2.0 (for back-compatibility reasons); any other value will result in the function returning an error. The new maximum size for a step will then be obtained by multiplying the original size by the enlargement step and subtracting 1. The current value of the enlargement step can be retrieved with this function: gfloat lqr_carver_get_enl_step LqrCarver * carver Choosing the resize order When the function lqr_carver_resize is asked to resize along both directions in a single step, it has to choose which direction to resize first. The resize order can be changed through this function: void lqr_carver_set_resize_order LqrCarver* carver LqrResizeOrder resize_order The possible values for resize_order are: LQR_RES_ORDER_HOR resize horizonally first (this is the default) LQR_RES_ORDER_VERT resize vertically first Choosing the side switch frequency When the function lqr_carver_resize is invoked, it chooses at each step the optimal seam to carve based on the relvance value for each pixel. However, in the case two seams are equivalent (which may happen when large portions of the image have the same colour, for example), the algorithm always chooses the seams from one side, which might be a problem (e.g. an object centered in the original image might not be centered any more in the resulting image). In order to overcome this effect, an option is given to automatically switch the favoured side during rescaling, at the cost of a slightly worse performance. The number of times such a switching event occurs for each rescale operation can be set using the function: void lqr_carver_set_side_switch_frequency LqrCarver* carver guint switch_frequency The default value for newly created &carv_obj; objects is 0, which is equivalent to disabling this feature. Giving a value greater than the number of pixels by which to rescale produces a switch for each pixel, therefore you could set switch_freqency to a ridicolously high value in order to be sure to get this effect. As for the final result, a very small value (e.g. 1 to 4) will normally suffice to balance the left and right side of the image (or the top and the bottom sides for vertical rescalings), without noticeable computational costs. However, in order to obtain a smoother behaviour for the visibiliy map, i.e. for the intermediate steps, higher values may be required. Using the cache By default, the library tries to cache some quantities in order to save computational time. The cache may be disabled in order to save memory instead, using this function: void lqr_carver_set_use_cache LqrCarver* carver gboolean use_cache To disable the cache, set use_cache to FALSE. To re-enable it back, set it to TRUE. Dealing with the visibility maps (the seams) Dumping the visibility map The visibility map can be saved at any moment by calling the function: LqrVMap* lqr_vmap_dump LqrCarver* carver This function will return a pointer to a newly allocated &vmap_obj; object, or &ret_null; in case of failure. See also the section "The visibility map objects". Storing the visibility maps By default, the computed visibility maps are wasted. Instead of saving them individually, it is possible to automatically dump them at the end of the carving process, attaching them to their associated &carv_obj;. In order to activate this feature, the following function has to be called: void lqr_carver_set_dump_vmaps LqrCarver* carver This will have the effect of dumping the visibility map each time lqr_carver_resize is invoked, and storing it internally. When resizing along both directions, two maps will be dumped, one for each direction. In order to revert the effect of lqr_carver_set_dump_vmaps, thus stopping the automatic dumping, use the function void lqr_carver_set_no_dump_vmaps LqrCarver* carver Alternatively, the internal storage mechanism can be called over the current visibility map at any given moment by calling this function: LqrRetVal lqr_vmap_internal_dump LqrCarver* carver The dumped maps are stored inside &vmap_obj; objects, and these are attached to their corresponing &carv_obj; object through a linked list, whose type is &vmapl_obj; Accessing the internally attached visibility maps To access the maps attached to a carver one has first to obtain the pointer to the list, with the function: LqrVMapList* lqr_vmap_list_start LqrCarver* carver Then, one can iterate through the attached maps by using these two functions: LqrVMap* lqr_vmap_list_current LqrVMapList* list LqrVMapList* lqr_vmap_list_next LqrVMapList* list Here is a sample code usage: Accessing visibility maps #1 LqrVMap *vmap; LqrVMapList *list; list = lqr_vmap_list_start (carver); while (list) { vmap = lqr_vmap_list_current (list); /* ... do something on vmap ... */ list = lqr_vmap_list_next (list); } The maps will always be accessed in the order in which they were dumped. Alternatively, one can apply a function to all the elements of the list, through this function: LqrRetVal lqr_vmap_list_foreach LqrVMapList* list LqrVMapFunc func gpointer data To use this second method, you'll need to define a function first, as in this sample code: Accessing visibility maps #2 LqrRetVal my_func (LqrVMap vmap, gpointer data) { /* ... do something on vmap ... */ return LQR_OK; } LqrVMapList *list; list = lqr_vmap_list_start (carver); lqr_vmap_list_foreach (list, my_func, NULL); In the above example, no data is actually passed on to the function. In actual code the call to lqr_vmap_list_foreach should be protected to test its return value, which is &err_ok; if all my_func calls have been successful, or it will hold the first non-successful return value from my_func. The visibility map objects The &vmap_obj; objects contain an int buffer with the actual map data (plain array, ordered by row), plus all the information needed to be able to recover it from scratch. The information can be extracted with these functions: gint* lqr_vmap_get_data (&vmap_obj;* vmap); gint lqr_vmap_get_width (&vmap_obj;* vmap); gint lqr_vmap_get_height (&vmap_obj;* vmap); gint lqr_vmap_get_orientation (&vmap_obj;* vmap); gint lqr_vmap_get_depth (&vmap_obj;* vmap); The first one returns a pointer to the data buffer. The orientation of the map is 0 if the map is to be used for horizontal rescaling, 1 otherwise. The depth of the map is the maximum amount of rescaling possible with that map, either shrinking or enlarging. Reading visibility maps data If we have a &vmap_obj; pointer called vmap, we could access the value at (x,y) by: gint *buffer; gint width; gint vis; buffer = lqr_vmap_get_data (vmap); width = lqr_vmap_get_width (vmap); vis = buffer[y * width + x]; Uninitialised points will yield vis = 0. For initialised points, vis will store a positive value between 1 (least visible points, the first to be carved away or to be duplicated) and (¶m_depth; + 1) (most visible points, the last to be carved away or to be duplicated). If the orientation is 0, the map allows resizing in the whole range form (¶m_w; - ¶m_depth;) to (¶m_w; + ¶m_depth;). If the orientation is 1, the analogue formula holds with ¶m_h; in place of ¶m_w;. Importing a visibility map in a carver Having an &vmap_obj; object, one can load it in an &carv_obj; simply by calling this function: LqrRetVal lqr_vmap_load LqrCarver* carver LqrVMap* vmap The carver must not to be initialised, neither before nor after invoking this function. This implies that the map cannot be updated, and that it will only be possible to resize the carver by an amount ¶m_depth; along the orientation given by lqr_vmap_orientation. The enlargment step is also set to its maximum, 2.0. Invoking lqr_carver_resize with an out-of-bounds argument results in a fatal error (i.e. it returns &err_err;). Do not attach other carvers after you have loaded a visibility map (see also the Attaching extra images section). Saving and loading visibility maps to/from files The library does not include methods to load/save visibility maps to/from files. However, a way to do so is shown in the demo program `liquidrescale' in the `examples' directory. Attaching extra images Attaching a carver Given an &carv_obj; object, it is possible to attach an arbitrary number of extra carvers to it: these will passively undergo the same carving process as the root carver. In order for this to be possible, the carvers must be all of the same size. The function to use is simply: LqrRetVal lqr_carver_attach LqrCarver* carver LqrCarver* aux This attaches aux to carver. It is not necessary that the parent &carv_obj; is activated. In fact, a carver can be attached to a carver which is itself attached to another one. Needless to say, no resizing operation should be done directly on an &carv_obj; once it has been attached to another &carv_obj;, and neither should the cancel method be invoked directly on them. The carvers always have to be attached before loading visibility maps. Accessing attached carvers Attached carvers can be read-out in the same way as their parents. There are however also methods to span all them, in a way very similar to that in which internally dumped &vmap_obj;'s are accessed, but &vmapl_obj; objects are substitued in this case by &carvl_obj; objects. First, the starting point of the list has to be retreived through: LqrCarverList* lqr_carver_list_start LqrCarver* carver Then, one can iterate through the attached carvers by using these two functions: LqrCarver* lqr_carver_list_current LqrCarverList* list LqrCarverList* lqr_carver_list_next LqrCarverList* list Here is a sample code usage: Accessing attached carvers #1 LqrCarver *aux; LqrCarverList *list; list = lqr_carver_list_start (carver); while (list) { aux = lqr_carver_list_current (list); /* ... do something on aux ... */ list = lqr_carver_list_next (list); } The carvers will always be accessed in the order in which they were attached. Alternatively, one can apply a function to all the elements of the list (and recursively to all the elements of their attached lists, if there are any), through this function: LqrRetVal lqr_carver_list_foreach_recursive LqrCarverList* list LqrCarverFunc func LqrDataTok data To use this second method, you'll need to define a function first, as in the following sample code: Accessing attached carvers #2 LqrRetVal my_func (LqrCarver *aux, LqrDataTok data) { /* ... do something on aux ... */ return LQR_OK; } LqrCarverList *list; LqrDataTok data_tok; list = lqr_carver_list_start (carver); data_tok->data = NULL; lqr_carver_list_foreach_recursive (list, my_func, data_tok); The data to be passed on to the LqrCarverFunc is of type LqrDataTok. This is defined as a union, with the following fields: &carv_obj;* carver gint integer gpointer data In the above example, no data is actually passed on to the function. In actual code, the call to lqr_carver_list_foreach_recursive should be protected to test its return value, which is &err_ok; if all my_func calls have been successful (or if the list is empty), or it will hold the first non-successful return value from my_func. Progress indicators By default, the resizing performed silently. However, it is possible to define progress report functions, to receive feedback while the resizing is in progress. This is done through the &prog_obj; objects. Creating and attaching a progress report object A &prog_obj; object is created through the function: LqrProgress* lqr_progress_new and can be associated to an &carv_obj; object through this function: void lqr_carver_set_progress LqrCarver* carver LqrProgress* p Setting up progress hooks Newly created progress objects are inactive, and need to be set up. First, hook functions have to be set, which specify the action to take as the rescaling process starts, progresses, and ends, by using the functions: LqrRetVal lqr_progress_set_init (&prog_obj; * p, LqrProgressFuncInit init_func) LqrRetVal lqr_progress_set_update (&prog_obj; * p, LqrProgressFuncUpdate update_func) LqrRetVal lqr_progress_set_end (&prog_obj; * p, LqrProgressFuncEnd end_func) as in this sample piece of code: Setting progress hooks LqrProgress *p; p = lqr_progress_new(); lqr_progress_set_init (p, my_init); lqr_progress_set_update (p, my_update); lqr_progress_set_end (p, my_end); The above example requires that the hook functions my_init, my_update and my_end are defined as in the following sample declarations: Progress hooks declaration LqrRetVal my_init (const gchar *init_message); LqrRetVal my_update (gdouble percentage); LqrRetVal my_end (const gchar *end_message); Initial and ending progress messages The init and end hooks will be called at the beginning and at the end of each rescaling operation by function lqr_carver_resize. The messages that will be passed to these hooks will change, depending if the resizing is occurring in the horizontal or in the vertical direction. The defaults for newly created &prog_obj; objects are: Default progress messages init end horizontal &prog_init_w_mess; &prog_end_w_mess; vertical &prog_init_h_mess; &prog_end_h_mess;
These can be changed using these functions: LqrRetVal lqr_progress_set_init_width_message (&prog_obj; *p, const gchar * message) LqrRetVal lqr_progress_set_init_height_message (&prog_obj; *p, const gchar * message) LqrRetVal lqr_progress_set_end_width_message (&prog_obj; *p, const gchar * message) LqrRetVal lqr_progress_set_end_height_message (&prog_obj; *p, const gchar * message) Progress update step The update hook will be called at regular intervals, and it will be passed the completion percentage as the argument. The update step can be specified through: LqrRetVal lqr_progress_set_update_step LqrProgress* p gfloat update_step The default step is 0.02 (i.e. 2%). Releasing the memory &carv_obj; objects can be destroyed using this function: void lqr_carver_destroy LqrCarver* carver This function also destroys any attached object, thus it should never be called on attached carvers. &vmap_obj; objects can be destroyed using this function: void lqr_vmap_destroy LqrVMap* vmap LqR library API reference Types defined by the library LqrRetVal 3 LqrRetVal the return value of many &lqrl; functions Description The return type of many functions in the &lqrl; is LqrRetVal, which is an enum type that can take these values: &err_ok; everyting OK &err_err; generic fatal error &err_nomem; not enough memory &err_cancel; action cancelled by the user The user should handle the error values explicitly at each function call returning this type. See also LqrColDepth 3 LqrColDepth carver objects colour depth specification Description The default &carv_obj; object constructor lqr_carver_new uses a colour depth of 8 bits per channel, and therefore its input must be an array of unsigned chars. However, the &carv_obj; objects can handle images of grater colour depth, if they are created with the lqr_carver_new_ext constructor. The possible colour depths are specified through variables of type LqrColDepth, which is an enum type; its possible values, and the type of the input buffer associated with them, are: &col_depth_8i; use type guchar (8 bit unsigned integers) - the default &col_depth_16i; use type guint16 (16 bit unsigned integers) &col_depth_32f; use type gfloat (32 bit floating point) &col_depth_64f; use type gdouble (64 bit floating point) These values are also relevant when reading out a &carv_obj; object with the functions lqr_carver_scan_ext or lqr_carver_scan_line_ext, since the readout buffer must be cast to the appropriate type to be actually read. The colour depth of an &carv_obj; object can be obtained with the function lqr_carver_get_col_depth. See also LqrImageType 3 LqrImageType carver objects image type (colour model) specification Description The &carv_obj; objects use knowledge about the image type they're working on in order to compute correctly some quantities (e.g. the brightness) for the automatic feature detection. Image types are set automatically by the constructors, but they can also be specified manually using quantities of the type LqrImageType, which is an enum which can take these values: &img_type_grey; &img_type_greya; &img_type_rgb; &img_type_rgba; &img_type_cmy; &img_type_cmyk; &img_type_cmyka; &img_type_custom; Use the function to set the image type of a carver, and the function to read it out. See also Carver objects lqr_carver_new 3 lqr_carver_new lqr_carver_new_ext the &carv_obj; object constructors #include <lqr.h> LqrCarver* lqr_carver_new guchar* buffer gint width gint height gint channels LqrCarver* lqr_carver_new_ext void* buffer gint width gint height gint channels LqrColDepth colour_depth Description The functions lqr_carver_new and lqr_carver_new_ext create a new &carv_obj; object from an image of size ¶m_w; * ¶m_h; with ¶m_channels; colour channels. The image must be stored in buffer as a plain array of unsigned chars (for lqr_carver_new) or the appropriate type cast to void (for lqr_carver_new_ext), ordered by row, then by column, then by colour channel. In the extended constructor lqr_carver_new_ext, the additional parameter colour_depth is required to specify the colour depth of the buffer (see for more information). After calling the function, the buffer will be owned by the &carv_obj; object and must not be accessed any more, unless you subsequently call the function. The image type is et automatically from the value of channels according to this table: Image types assigned by default channels type 1 &img_type_grey; 2 &img_type_greya; 3 &img_type_rgb; 4 &img_type_rgba; 5 &img_type_cmyka; >5 &img_type_custom;
Return value The return value is the address of the newly created &carv_obj; object, or &ret_null; in case of failure (insufficient memory). See also lqr_carver_destroy 3 lqr_carver_destroy the &carv_obj; object destructor #include <lqr.h> void lqr_carver_destroy LqrCarver* carver Description The function lqr_carver_destroy destroys the &carv_obj; object pointed to by carver, and all of its attched components (visibility maps and attached carvers). It must never be invoked over a carver which is attached to another one. This function will not release the memory buffer passed to if it was protected by calling . See also lqr_carver_init 3 lqr_carver_init activates an &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_init LqrCarver* carver gint delta_x gfloat rigidity Description The function lqr_carver_init initialises the &carv_obj; pointed to by carver, so that it can compute the visibility maps as needed upon calls of lqr_carver_resize. The parameter delta_x controls the maximum transversal step a seam can make. A value of 0 means straight seams. Normally, it is set to 1. The parameter rigidity can be used to add a negative bias to non-straight seams, and it is normally set to 0. Visibility maps must not be loaded with the function lqr_vmap_load when using this function, neither before nor after invoking it. Return value The return value follows the &lqrl; signalling system. See also lqr_carver_set_image_type 3 lqr_carver_set_image_type sets the image type of an &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_set_image_type LqrCarver* carver LqrImageType image_type Description The function lqr_carver_set_image_type sets the image type of the &carv_obj; pointed to by carver to image_type. If image_type is equal to &img_type_custom;, it is assumed that there are no alpha or black channels. You can set those independently using and . Return value The return value follows the &lqrl; signalling system.

Use a negative value for cahnnel_index to specify that no alpha channel is present. If the specified channel coincides with the current value of the black channel, the black channel is unset. Calling this function sets the image time of the carver to &img_type_custom;. Return value The return value follows the &lqrl; signalling system. See also lqr_carver_set_black_channel 3 lqr_carver_set_black_channel sets the black channel index in a &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_set_black_channel LqrCarver * carver gint channel_index Description The function lqr_carver_set_black_channel sets the black channel index of the image stored in the &carv_obj; pointed to by carver to channel_index (between 0 and channels - 1, where channels is the number of colour channels of the carver). Use a negative value for cahnnel_index to specify that no black channel is present. If the specified channel coincides with the current value of the alpha channel, the alpha channel is unset. Calling this function sets the image time of the carver to &img_type_custom;. Furthermore, the image color model will be assumed to be subtractive by the function when it computes the brightness or the luma. Return value The return value follows the &lqrl; signalling system. See also lqr_carver_resize 3 lqr_carver_resize liquid rescale a &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_resize LqrCarver* carver gint new_width gint new_height Description The function lqr_carver_resize performs the liquid rescaling over the &carv_obj; object pointed to by carver. If a visibility map was loaded through the function lqr_vmap_load, and the carver was not initialised, the resizing operations must be limited to the direction and the sizes included in the loaded map. If the carver was initialised through the function lqr_carver_init, there are no limitations to the final size. The resizing function can be called multiple times, and it will decide automatically whether the computation of the visibility map is necessary or not. In case it isn't, the function returns almost immediately, otherwise operations will proceed following the order given through the function lqr_carver_set_resize_order. Currently, on-the-fly rescaling without computation is only possible for a single direction at a time. If the new size (in one direction or in both) is greater than or equal to the original size multiplied by the enlargement step of the carver object (as obtained through ), the rescaling will be performed in multiple steps. At each step, the original size stored internally is reset to the new value; therefore, each step in the process can be bigger then the previous one. Whenever the resizing dirction changes (this may happen in a single call of the rescaling function or through multiple calls), or if performing a multiple steps enlargement as per the previous paragraph, the visibility map computed during the first direction rescale is dropped to make place for the one for the second (and the original size of the image is reset to the current value). These visibility maps can be saved by using the lqr_carver_set_vmap_dump function, for inspection or future use. Return value The return value follows the &lqrl; signalling system. It returns an error if trying to exceed the limitations of a loaded visibility map, or if passed a negative or null size. See also lqr_carver_flatten 3 lqr_carver_flatten flatten a &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_flatten LqrCarver* carver Description The function lqr_carver_flatten can be used to discard the visibility map information and flatten the multi-size image contained in the &carv_obj; object pointed to by carver to its current state. It will also reset the internally stored original width and height, as if the image was just loaded in the &carv_obj; object. This function must only be invoked over initialised &carv_obj; objects. This function is called internally each time the rescaling direction changes, or at each new step in a multiple-step enlargement, but, when calling it manually, the discarded visibility map will not be dumped automatically by it; use the functions or in order to save it before invoking this function. Return value The return value follows the &lqrl; signalling system. Errors can occur for non-initialised &carv_obj; objects or in case of insufficient memory. See also lqr_carver_cancel 3 lqr_carver_cancel cancel ongoing operations on a &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_cancel LqrCarver* carver Description The function lqr_carver_cancel can be used to cancel an ongoing operation which is currently being performed on the the &carv_obj; object pointed to by carver. It must be used asynchronouly, from within an independent thread. If an operation is in fact cancelled by this function, the function which was performing the operation will return the value &err_cancel;, and so will do any other operation successively called on the same &carv_obj; object whose return type is LqrRetVal; otherwise it will have no effect. Whenever a function returns &err_cancel;, it means that the &carv_obj; object is in an inconsistent state, and, since there is currently no way to recover from this situation, any further operation on that object must be avoided, and it must be destroyed. This function will fail if invoked over attached &carv_obj; objects. Return value The return value follows the &lqrl; signalling system. However, it can be called multiple times, so it will never return &err_cancel; itself. See also lqr_carver_scan_reset 3 lqr_carver_scan_reset reset the readout cursor of a multi-size image #include <lqr.h> void lqr_carver_scan_reset LqrCarver* carver Description The function lqr_carver_scan_reset resets the readout pointer associated with the &carv_obj; object pointed to by carver to the start of the image. (Normally, calling this function isn't needed, as the pointer is reset automatically whenever an operation is performed or once a readout has completed.) See also lqr_carver_scan 3 lqr_carver_scan lqr_carver_scan_ext read out a multi-size image one pixel at a time #include <lqr.h> gboolean lqr_carver_scan LqrCarver* carver gint* x gint* y guchar** rgb gboolean lqr_carver_scan_ext LqrCarver* carver gint* x gint* y void** rgb Description The functions lqr_carver_scan and lqr_carver_scan_ext are used to read out the multi-size image contained in the &carv_obj; object pointed to by carver one pixel at a time. They store the pixel coordinates in the variables pointed to by x and y, and the pixel content in the array pointed to by rgb; then they move the readout pointer to the next pixel, or they reset it if the end of the image is reached. The first one must only be used on the &carv_obj; objects created with lqr_carver_new, i.e. with 8-bit images, while the second one is general (see ), but the rgb pointer must be cast to the appropriate type to be used (i.e pass the address of a pointer to void to the function lqr_carver_scan_ext, then cast it to a pointer of the appropriate type and use this last one for reading the output). The rgb variable will point to an array which is internal to the &carv_obj; object, so there is no need to allocate memory for it. However, it should only be accessed right after a call to the scan functions, and writing to it must be avoided. Return value These functions return &ret_true; in case the readout is successful and the end of the image was not reached, &ret_false; otherwise. If lqr_carver_scan is called over a non-8-bit &carv_obj; object, it will return &ret_false;.

Return value This function returns &ret_true; in case the image is going to be scanned by row, &ret_false; in case it is going to be scanned by column; See also lqr_carver_scan_line 3 lqr_carver_scan_line lqr_carver_scan_line_ext read out a multi-size image one line at a time #include <lqr.h> gboolean lqr_carver_scan_line LqrCarver* carver gint* n guchar** rgb gboolean lqr_carver_scan_line_ext LqrCarver* carver gint* n void** rgb Description The functions lqr_carver_scan_line and lqr_carver_scan_line_ext are used to read out the multi-size image contained in the &carv_obj; object pointed to by carver one line at a time. They store the line number (row or column) in the variable pointed to by n and the colour values in the array pointed to by rgb; then they move the readout pointer to the next line, or they reset it if the end of the image is reached. The first one must only be used on the &carv_obj; objects created with lqr_carver_new, i.e. with 8-bit images, while the second one is general, but the rgb pointer must be cast to the appropriate type to be used (i.e pass the address of a pointer to void to the function lqr_carver_scan_line_ext, then cast it to a pointer of the appropriate type and use this last one for reading the output). Use the function before calling these to know whether your image will be scanned by row or by column. Return value These functions return &ret_true; in case the readout is successful and the end of the image was not reached, &ret_false; otherwise. If lqr_carver_scan_line is called over a non-8-bit &carv_obj; object, it will return &ret_false;.

The reference width is set as the original height at carver initialization, and reset any time the carver gets subsequently flattened, either explicitly through or implicitly when the rescale direction changes or an enlargment beyond the maximum enlargement step is performed.

The returned value is strictly greater than 1 and less than 2. See also lqr_carver_get_orientation 3 lqr_carver_get_orientation get the orientation of a &carv_obj; object #include <lqr.h> gint lqr_carver_get_orientation LqrCarver* carver Description The function lqr_carver_get_orientation returns the current orientation of the visibility map internal to the &carv_obj; object pointed to by carver, which is 0 if the last rescale operation has been in the horizontal direction, 1 if it has been in the vertical direction. See also lqr_carver_get_depth 3 lqr_carver_get_depth get the depth of a &carv_obj; object #include <lqr.h> gint lqr_carver_get_depth LqrCarver* carver Description The function lqr_carver_get_depth returns the current depth of the visibility map internal to the &carv_obj; object pointed to by vmap, i.e. the maximum amount of scaling which can be performed with respect to the internal reference sizes in the current orientation without updating the internal map. See also lqr_carver_set_enl_step 3 lqr_carver_set_enl_step set the enlargement step of a &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_set_enl_step LqrCarver* carver gfloat enl_step Description The function lqr_carver_set_enl_step sets the enlargement step of the &carv_obj; object pointed to by carver to the value specified in enl_step, which must be strictly greater than 1 and less than 2. The enlargement step is the maximum enlargement ratio (with respect to either the original width or original height of carver) which the function lqr_carver_resize applies in a single step; if that function is asked a greater enlargement, it divides the process in multiple steps (and updates the original sizes accordingly at each new step - these can be readout at any time with and ). The default value for new &carv_obj; objects is 2.0. Return value The return value follows the &lqrl; signalling system. &err_err; is returned if the enl_step parameter is out of bounds. See also lqr_carver_set_resize_order 3 lqr_carver_set_resize_order set &carv_obj; object resize order #include <lqr.h> void lqr_carver_set_resize_order LqrCarver* carver LqrResizeOrder resize_order Description When the function is invoked and both the horizontal and vertical sizes are different from the current ones, the rescaling occurs first in one direction and then in the other. The function lqr_carver_set_resize_order can be used to set which direction to rescale first for the &carv_obj; object pointed to by carver. The parameter resize_order can take either the value LQR_RES_ORDER_HOR (horizontal rescale first) or LQR_RES_ORDER_VERT (vertical rescale first). By default, when an &carv_obj; object is created, the value is set to LQR_RES_ORDER_HOR See also lqr_carver_set_dump_vmaps 3 lqr_carver_set_dump_vmaps lqr_carver_set_no_dump_vmaps set the visibility maps autodump for an &carv_obj; object #include <lqr.h> void lqr_carver_set_dump_vmaps LqrCarver* carver void lqr_carver_set_no_dump_vmaps LqrCarver* carver Description Invoking function lqr_carver_set_dump_vmaps over the &carv_obj; object pointed to by carver has the effect of activating the automatic dumping of visibility maps at each rescale operation (which by default is turned off). Rescale operations involving both directions will dump two maps. The dumped maps will be attached to the &carv_obj; object and can be accessed at any later time using the functions or a combination of , and . Using this setting is pointless if the &carv_obj; object is not initialised. The function lqr_carver_set_no_dump_vmaps reverts the effect of the previous one (but the maps dumped so far will be kept). Note that it is also possible to dump the visibility maps manually; however, using the automatic dump is the only way to get intermidiate maps when the function performs the rescaling in both directions, or in more than one step. See also lqr_carver_set_side_switch_frequency 3 lqr_carver_set_side_switch_frequency set &carv_obj; object side switch frequency #include <lqr.h> void lqr_carver_set_side_switch_frequency LqrCarver* carver guint switch_frequency Description When the function is invoked, it computes a relevance value for each pixel in the image, then chooses the optimal seam to carve based on such relvance values. However, in the case two seams are equivalent (which may happen when large portions of the image have the same colour, for example), the algorithm always chooses the seams from one side. In order to overcome this effect, an option is given to automatically switch the favoured side during rescaling, at the cost of a slightly worse performance. The function lqr_carver_set_side_switch_frequency sets the side switch frequency to switch_frequency for the &carv_obj; object pointed to by carver. This will have the effect that, for each rescale operation, the favoured side will be switched switch_frequency times (or as much times as the number of pixels to rescale). The default value for newly created &carv_obj; objects is 0. As for the final result, a very small value (e.g. 1 to 4) will normally suffice to balance the left and right side of the image (or the top and the boddom sides for vertical rescalings), without noticeable computational costs. However, in order to obtain a smoother behaviour for the visibiliy map, i.e. for the intermediate steps, higher values may be required.

Progress indicators objects are created with the function . By default, no progress indicator is used.

It must be used before any resizing-related operation takes place, either after the carver construction or after the calls to or .

By default, the caching is on. See also lqr_carver_attach 3 lqr_carver_attach attach an &carv_obj; to another &carv_obj; #include <lqr.h> LqrRetVal lqr_carver_attach LqrCarver* carver LqrCarver* aux Description The function lqr_carver_attach is used to attach an &carv_obj; object (pointed to by aux) to another one (pointed to by carver). This will have the effect that each operation performed over the carver object will be reflected on aux (they will share the same visibility map). This function must not be used after a visibility map was loaded into the base object (the one pointed to by carver). The object pointed to by aux must have the same original size as the base object. Note that the original size information is reset whenever a flattening operation occurs, or the rescaling direction changes, so that this function should be called befor rescaling occurs. There is no limitation on the number of &carv_obj; objects which is possible to attach. Nesting is also possible. It is irrelevant if the aux carver is initialised or not; from the moment of attachment, it will passively undergo all transformations performed over carver. Return value The return value follows the &lqrl; signalling system. &err_err; is returned if the sizes of carver and aux don't match.

The returned value is &ret_null; if there are no attached carvers. Use the functions and to access the list element individually, or the function to operate on whole lists.

The parameter data is used to pass arguments to the function. The list value should be obtained through the function . The order in the list will then follow the one in which carver objects were attached. The function func is of type LqrCarverFunc, whose prototype is defined by: typedef LqrRetVal (*LqrCarverFunc) (LqrCarver *carver, LqrDataTok data); The data argument is of type LqrDataTok, which is defined as a union with the following fields: &carv_obj;* carver gint integer gpointer data The function lqr_carver_list_foreach_recursive is equivelant to lqr_carver_list_foreach, but it works recursively if the &carv_obj; objects in list have themselves other attached &carv_obj; objects attached. In this case, the function func will be applied to each element of the list and to each element of the attached list recursively, before moving on to the next element. See also Visibiliy maps lqr_vmap_new 3 lqr_vmap_new the &vmap_obj; object constructor #include <lqr.h> LqrVMap* lqr_vmap_new gint* buffer gint width gint height gint depth gint orientation Description The function lqr_vmap_new is the constructor for &vmap_obj; objects. It can be used to convert saved data in a format which can be loaded in an &carv_obj; object. The parameter buffer must point to an an array of width * height ints holding the visibility information. The parameter depth represents the maximum possible amount of rescaling with the given map. The parameter orientation must be 0 if the map is to be used for horizontal rescaling, 1 if it is to be used for vertical rescaling. Visibility maps format The buffer must be an array of integers of size width * height. For an horizontally oriented visibility map, the format is as such: each row must contain all values between 1 and depth (included) exactly once, with low values indicating the pixels which will be operated on first during rescaling. All other pixels must be 0, which means that they won't be affected by rescaling. Such a map allows for horizontal rescaling in the range from width - depth to width + depth. The same applies to vertically oriented visibility maps, with columns in place of rows and height in place of width. Return value The function returns the newly created &vmap_obj; if successful, or &ret_null; in case of insufficient memory.

The returned value is &ret_null; if there are no dumped visibility maps.

The parameter data is used to pass arguments to the function. The list value should be obtained through the function . The function func is of type LqrVMapFunc, whose prototype is defined by: typedef LqrRetVal (*LqrVMapFunc) (LqrVMap *vmap, gpointer data); The data argument is of type gpointer, which is just a pointer to void.

The possible values for ef_ind are: LQR_EF_GRAD_XABS absolute value of the brightness gradient in the direction of the rescaling (this is the default) LQR_EF_GRAD_SUMABS sum of absolute values of the brightness gradients in both directions LQR_EF_GRAD_NORM norm of the brightness gradient LQR_EF_LUMA_GRAD_XABS absolute value of the luma gradient in the direction of the rescaling LQR_EF_LUMA_GRAD_SUMABS sum of absolute values of the luma gradients in both directions LQR_EF_LUMA_GRAD_NORM norm of the luma gradient LQR_EF_NULL null All of the above gradient functions have a radius of 1 pixel. Return value The return value follows the &lqrl; signalling system. See also lqr_carver_set_energy_function 3 lqr_carver_bias_set_energy_function set a custom energy function for a &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_set_energy_function LqrCarver* carver LqrEnergyFunc en_func gint radius LqrEnergyReaderType reader_type gpointer extra_data Description The function lqr_carver_set_energy_function assigns the energy function en_func to the &carv_obj; object pointed to by carver (see below for more details on custom functions definitions). The parameter radius determines the size of the square region which affects the computation around each pixel (the side of the square will be 2 * radius + 1 pixels long). The parameter reader_type sets the reader type used when reading the image, and therefore it determines what quantity will be passed on to the function en_func (see below for more details on reader types). The parameter extra_data is a (void) pointer which can be used to pass on additional values to the function ef_func. Custom functions definition The function en_func must be of type LqrEnergyFunc, whose prototype is defined by: typedef gfloat (*LqrEnergyFunc) (gint x, gint y, gint img_width, gint img_height, LqrReadingWindow * rwindow, gpointer extra_data); Such a function is expected to compute the energy at pixel ¶m_x;, ¶m_y; based on the knowledge of the current image size (obtained from ¶m_w; and ¶m_h;) and the content of the image in a square around that pixel, which is passed through the rwindow reading window. In most cases, the parameters ¶m_x;, ¶m_y;, ¶m_w; and ¶m_h; would only be used to determine whether the region under consideration is at the image boundary or not. The rwindow content must be read using the function . Reader types The LqrEnergyReaderType is an enum which can take these values (also noted is the number of channels of the corresponging reading window): LQR_ER_BRIGHTNESS brightness (1 channel) LQR_ER_BRIGHTNESS luma (1 channel) LQR_ER_RGBA RGBA (4 channels) LQR_ER_CUSTOM read the normalised image channels as they are (as many channels as the image has) These readouts always return values beetween 0 and 1. Note that these readouts may have special meanings depending on the image type: for LQR_GREY_IMAGE, LQR_GREYA_IMAGE and LQR_CUSTOM_IMAGE images, the LQR_ER_LUMA readout will yield the same result as LQR_ER_BRIGHTNESS for LQR_CUSTOM_IMAGE images, the LQR_ER_BRIGHTNESS readout will return the average pixel value (additive, i.e. if a black channel is present the channel values will be inverted and multiplied by the black channel inverse), multiplied by the alpha channel value. for LQR_CUSTOM_IMAGE images, the LQR_ER_RGBA readout cannot be used: it will always return 0 Return value The return value follows the &lqrl; signalling system. See also lqr_carver_get_energy 3 lqr_carver_get_energy lqr_carver_get_true_energy lqr_carver_get_energy_image get the energy map for a &carv_obj; object #include <lqr.h> LqrRetVal lqr_carver_get_energy LqrCarver* carver gfloat * buffer gint orientation #include <lqr.h> LqrRetVal lqr_carver_get_true_energy LqrCarver* carver gfloat * buffer gint orientation #include <lqr.h> LqrRetVal lqr_carver_get_energy LqrCarver* carver void * buffer gint orientation LqrColDepth col_depth LqrImageType image_type Description The function lqr_carver_get_energy writes the energy map of the &carv_obj; object pointed to by carver to the given buffer, in a format suitable for plotting: all values are in the range between 0 and 1, and the true values are mapped nonlinearly and stretched on this whole range, so that the differences between the middle values are enhanced with respect to very high or very low values. The orientation parameter must be either 0 to get the energy map used for horizontal scalings, or 1 to get the map for vertical scalings. The buffer must be allocated by the user before calling this function, and its size must be at least ¶m_w; * ¶m_h;, where ¶m_w; and ¶m_h; are the current width and height of the carver. The energy values are ordered by row first, then by column. The outcome will include the effect of the bias added to the carver, if any. This function can be called over non-initialised &carv_obj; objects, e.g. to provide previews on the effect of different energy functions, but it can also be invoked at any later time. Note, however, that in this latter case the carver could be flattened if necessary, therefore the function invocation is potentially destructive of the internal visibiliy map. The function lqr_carvet_get_true_energy is identical to the previous one, but the resulting buffer will contain the true energy, not scaled nor shifted. The function lqr_carver_get_energy_image is very similar to the function lqr_carveR_get_energy, but it can be used to fill directly an image buffer of the format specified through the additional parameters col_depth and image_type (see and ). The buffer must be passed as void*, but it must point to a memory area with sufficient allocated space for the chosen image type and colour depth. The image type cannot be &img_type_custom;. For any choice of the parameters describing the image, the resulting buffer will hold a greyscale image, ranging from black (lowest energy) to white (highest energy). The opacity (alpha) will be set to 1, if present. All the information will be stored in the black channel in &img_type_cmyk; and &img_type_cmyka; image types. Return values The return values follow the &lqrl; signalling system. The function lqr_carver_get_energy_image will return an error if image_type is &img_type_custom;. See also lqr_rwindow_read 3 lqr_rwindow_read read the content of a &rwin_obj; object #include <lqr.h> gfloat lqr_rwindow_read LqrReadingWindow* rwindow gint x gint y gint channel Description The function lqr_rwindow_read returns the content of the reading window rwindow at point ¶m_x;, ¶m_y; and at channel channel. The coordinates ¶m_x; and ¶m_y; are relative to the rwindow centre, and they both can range from -radius to radius (extremes included), where radius can be obtained with the function . The function returns 0 when the coordinates are out of range, either because they are beyond the rwindow radius or because they are outside the image boundary. The channel parameter specifies which channel to read out; depending on the rwindow reader type, the range and meaning of this parameter changes: for the cases LQR_ER_BRIGHTNESS and LQR_ER_LUMA it must be 0, because the readout consists of a single channel, for LQR_ER_RGBA it must be between 0 and 3 (and then the readout will contain the RGBA information), while for LQR_ER_CUSTOM it must be one of the original image channels.

The function should be used instead. The function lqr_carver_set_gradient_function is still maintained for backwards compatibility reasons; its result is equivalent to calling lqr_carver_set_energy_function_builtin, with the following mapping between the argument gs_ind of the former and the argument ef_ind of the latter: LqrGradFuncType LqrEnergyFuncBuiltinType LQR_GF_XABS LQR_EF_GRAD_XABS LQR_GF_SUMABS LQR_EF_GRAD_SUMABS LQR_GF_NORM LQR_EF_GRAD_NORM LQR_GF_NULL LQR_EF_NULL See also Bias lqr_carver_bias_add 3 lqr_carver_bias_add_xy lqr_carver_bias_add_area lqr_carver_bias_add lqr_carver_bias_add_rgb_area lqr_carver_bias_add_rgb update an &carv_obj; bias #include <lqr.h> LqrRetVal lqr_carver_bias_add_xy LqrCarver* carver gdouble bias gint x gint y LqrRetVal lqr_carver_bias_add_area LqrCarver* carver gdouble* buffer gint bias_factor gint width gint height gint x_off gint y_off LqrRetVal lqr_carver_bias_add LqrCarver* carver gdouble* buffer gint bias_factor LqrRetVal lqr_carver_bias_add_rgb_area LqrCarver* carver gdouble* buffer gint bias_factor gint channels gint width gint height gint x_off gint y_off LqrRetVal lqr_carver_bias_add_rgb LqrCarver* carver gdouble* buffer gint bias_factor gint channels Foreword All the functions described in this page are used to add a bias to &carv_obj; objects. A positive biased pixel will be more likely to be avoided by seams, and thus be preserved during rescaling, while a negative bias has the opposite effect. All of these functions must be called before . If called multiple times, the biases added at each call will sum up. Adding a bias pixel by pixel The function lqr_carver_bias_add_xy adds a bias to the ¶m_x;, ¶m_y; pixel of the image loaded into the &carv_obj; object pointed to by carver A typical value for bias_factor would be 1000 (in absolute value). Adding a bias from a buffer The function lqr_carver_bias_add_area adds a bias to an area of the image loaded into the &carv_obj; object pointed to by carver. The parameter buffer must point to an array of doubles of size width * height, ordered first by rows, then by columns. The offset of the area relative to the image can be specified through x_off and y_off. The bias area can exceed the boundary of the image, and the offsets can be negative. The parameter bias_factor is an overall bias scale. A typical value when the buffer contents are of the order of 1 would be 1000 (in absolute value). The function lqr_carver_bias_add can be used when the area to add is of the same size of the image loaded in the &carv_obj; object and the offsets are 0. Adding a bias from an image The functions lqr_carver_bias_add_rgb_area and lqr_carver_bias_add_rgb are very similar to lqr_carver_bias_add_area and lqr_carver_bias_add, except that they use 8-bit multi-channel images as inputs. The number of channels in the image is passed via the parameter channels. The last channel is assumed to be the alpha (opacity) channel if channels is equal to 2 or greater than 3 (if this is not the case, use the previous functions). The bias is computed from the average of the colour channels, multiplied by the value of the alpha channel if present. For example, in RGBA images a white, nontransparent pixel is equivalent to a value of 1.0 when using a buffer in lqr_carver_bias_add_area. Return values The return values follow the &lqrl; signalling system.

Whenever one of these functions is called, a rigidity mask is activated for the whole image; the mask contains coefficients which modulate the value of the rigidity (which is set with ) in different areas of the image. It is very important to note that using no rigidity masks at all is equivalent to use a rigidity mask over the whole image with all the values set to 1.0, but, when first adding a rigidity mask to a &carv_obj; object, all the pixels outside the affected area will have their rigidity set to zero; therefore, the functions lqr_carver_rigmask_add_xy, lqr_carver_rigmask_add_area and lqr_carver_rigmask_add_rgb_area actually affect the whole image, despite their name. All the functions must be called after lqr_carver_init and before lqr_carver_resize. If called multiple times over the same area, new values will replace the old ones. Setting the rigidity mask pixel by pixel The function lqr_carver_rigmask_add_xy sets the rigidity mask value of the ¶m_x;, ¶m_y; pixel of the image loaded into the &carv_obj; object pointed to by carver Setting the rigidity mask from a buffer The function lqr_carver_rigmask_add_area adds a rigidity mask to an area of the image loaded in the &carv_obj; object pointed to by carver. The parameter buffer must point to an array of doubles of size width * height, ordered first by rows, then by columns. The offset of the area relative to the image are specified through x_off and y_off. The rigidity mask area can exceed the boundary of the image, and the offsets can be negative. The values in the given buffer are scaled by the overall rigidity value set when calling the function lqr_carver_init. The function lqr_carver_rigmask_add can be used when the area to add is of the same size of the image loaded in the &carv_obj; object and the offsets are 0. Setting the rigidity mask from an image The functions lqr_carver_rigmask_add_rgb_area and lqr_carver_rigmask_add_rgb are very similar to lqr_carver_rigmask_add_area and lqr_carver_rigmask_add, but use 8-bit multi-channel images as inputs. The number of channels in the image is passed via the parameter channels. The last channel is assumed to be the alpha (opacity) channel if channels is equal to 2 or greater than 3 (if this is not the case, use the previous functions). The rigidity value is computed from the average of the colour channels, multiplied by the value of the alpha channel if present. For example, in RGBA images a white, nontransparent pixel is equivalent to a value of 1.0 when using a buffer in lqr_carver_rigmask_add_area.

Stylesheets and a makefile are also provided to get html versions and manual pages. *) Issuing `make' or `make html' will produce the manual in html format, with the file `liblqr_manual.html' pointing to the manual index. *) Issuing `make onepage' will produce the manual in html formal in a single page, under the name `liblqr_manual_onepage.html'. *) Issuing `make man' will produce the man pages in the directory `man3/'. However, these assume that `xsltproc' is installed in your system and that your docbook specifications are located at: html: /usr/share/xml/docbook/stylesheet/nwalsh/html/chunk.xsl onepage: /usr/share/sgml/docbook/stylesheet/xsl/nwalsh/html/docbook.xsl man: /usr/share/xml/docbook/stylesheet/nwalsh/manpages/docbook.xsl If this is not the case, edit the `lqr_style.xsl', `lqr_style_onepage.xsl' and `lqr_style_man.xsl' files accordingly. liblqr-1-0.4.1/examples/0000777000175000017500000000000011202134135011752 500000000000000liblqr-1-0.4.1/examples/liquidrescale.cpp0000644000175000017500000010577411201666506015251 00000000000000/* LiquidRescaling Library DEMO program * Copyright (C) 2007-2009 Carlo Baldassi (the "Author") . * All Rights Reserved. * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; version 3 dated June, 2007. * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The first one is a full-featured command-line application, while the second one is just a minimalistic version of the first. These programs are meant to be used as reference code, and to integrate the documentation, and they are fully commented. The provided Makefile is also meant to demonstrate the required compilation options, and it is commented as well. In order to compile the two programs, you will need the pngwriter library to be properly installed on your system. If your distribution doesn't include it, you can download it from: http://pngwriter.sourceforge.net/ Once compiled, you can see the command line options by issuing: ./liquidrescale --help or ./liquidrescale-basic --help liblqr-1-0.4.1/README0000644000175000017500000001005411202131310010720 00000000000000 LiquidRescale library 0.4.0 =========================== Table of contents ----------------- * Introduction + Library features * Installation + Requirements + Normal setup * Using the library * References * Copyright + Introduction -------------- The LiquidRescale (lqr) library provides a C/C++ API for performing non-uniform resizing of images by the seam-carving technique. ++ Library features The library takes images in plain array format as input and converts them to a multi-size representation. Following is a list of features: * Easy to use and fully documented API * Currently supports 8 bit to 64 bit per channel images * Support for different color models: grayscale, RGB, CMY and their variants, and even custom ones * Areas in the image can be marked for preservation or discard, or for additional seam rigidity * Once the image has been fully processed, the scaling can be done in real-time. In fact, the information can be saved and read out later without any further processing * The resizing is done with a single function which automatically performs all the necessary operations; it can also work in successive steps without wasting computational time * Possibility to tune the carving operation by letting the seams be less connected, or more rigid, or both (the rigidity can be also be modulated through a mask, to get a differnet behaviour in different areas of the image) * Can export and import the visibility map (the seams) * Other images can be attached and undergo the same carving process as the parent image * The automatic feature detection algorithm can be tuned by selecting among different energy gradient functions, and easily defining custom ones * Reports progress through a customisable interface * A signalling system permits to cleanly handle errors * Portable to all major OS's + Installation -------------- ++ Dependencies The lqr library depends on the glib-2.0 libraries ++ Normal setup The build package uses autotools and libtool, so the installation commands on Unix systems are simply ./configure && make && sudo make install The last step requires administrative privileges. (Note: the default installation path is /usr since version 0.4) If you want to also install the man pages for the library functions, add the option `--enable-install-man' in the call to ./configure. If you want to disable legacy macro names which do not begin with LQR_ then add the option `--diable-legacy-macros' See the INSTALL file for a full description. + Using the library for development ------------------------------------- In order to use the library functions and structures from a C or C++ program, you have to add this include line in your program: #include At compile time, you can take advantage of pkg-config to set the proper flags. In the `examples' directory you can find a basic example program, `liquidrescale-basic', and a full-featured demo program, `liquidrescale', together with a simple Makefile. Both programs are fully commented. The "basic" version demonstrates how to use the strictly-needed library functions, while the full version uses almost all of the API methods provided. The Makefile shows how to set the compilation flags. See the README file in that directory for more information. The complete manual and reference for the library, together with some additional notes, can be found in the `docs' directory in docbook format. The reference is also provided in man page format. The makefile in that directory (hopefully) generates the manual in html format, using xsltproc; then you'll find the index named after `liblqr_manual_index.html'. See the README file in that directory for further information. + References ------------ The library implements the algorithm described in the paper "Seam Carving for Content-Aware Image Resizing" by Shai Avidan and Ariel Shamir, which can be found at http://www.faculty.idc.ac.il/arik/imret.pdf + Copyright ----------- Copyright (C) 2007-2009 Carlo Baldassi liblqr-1-0.4.1/configure.ac0000644000175000017500000001072711202133034012342 00000000000000dnl Process this file with autoconf to produce a configure script.

That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read . liblqr-1-0.4.1/COPYING.LESSER0000644000175000017500000001672710776235417012140 00000000000000 GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library. liblqr-1-0.4.1/ChangeLog0000644000175000017500000000614111202133142011621 000000000000002009-05-12 Carlo Baldassi * Forgot (undocumented) legacy macro 2009-05-09 Carlo Baldassi * Changed lqr_carver_get_[true_]energy * Added lqr_carver_get_energy_image 2009-05-05 Carlo Baldassi * Updated the example files with the new features 2009-05-04 Carlo Baldassi * Added lqr_carver_bias/rigmask_clear 2009-05-03 Carlo Baldassi * Changed CATCH* macros to LQR_CATCH* * No alpha by default for LQR_CUSTOM_IMAGE * Improved set alpha/black channel * Bias activates energy (for using with lqr_carver_get_energy) * Fixes in lqr_carver_bias/rigmask_add_area * Added lqr_carver_rigmask_add_xy * Don't call transpose when adding rigmasks * Rigmask init set to 0 instead of 1 * Removed energy previews * Added lqr_carvre_get_true_energy 2009-04-28 Carlo Baldassi * Heavily optimised the update_mmap code * Progress report spans whole sessions instead of being divided into steps when enlagement exceeds the enl_step 2009-04-27 Carlo Baldassi * New framework for energy definition, including energy previews * Added lqr_carver_bias_add_xy * Better bias managment (saves memory if bias is not used, no unnecessary transpositions) 2009-04-16 Carlo Baldassi * Added cancel methods and structures * Fixed recursiveness of some calls to lqr_carver_list_foreach * Fixed return value of lqr_carver_resize 2009-04-09 Carlo Baldassi * Added lqr_carver_set_preserve_input_image * Version bump 0.4 2009-04-08 Carlo Baldassi * Fixed bug with 16-bit images 2009-01-26 Carlo Baldassi * Added readouts for current visiblity map 2008-11-01 Carlo Baldassi * Bugfix in update_mmap causing crashes with delta_x > 1 * Removed unnecessary includes of stdio.h * Added debug_checkrows 2008-10-22 Carlo Baldassi * Moved classes definitions to private headers 2008-10-21 Carlo Baldassi * Removed 2-fold scale-up limit, added enl_step setting 2008-10-12 Carlo Baldassi * Added 32 bit and 64 bit floating point support * Added get_col_depth * Turned all internal floating point maps from gdouble to gfloat * Collapsed all the nonstandard constructors and span functions to a single version (*_ext) 2008-09-04 Carlo Baldassi * Added set_no_dump_vmaps 2008-09-04 Carlo Baldassi * Hid private symbols 2008-07-30 Carlo Baldassi * Optimized vsmap memory management * Bugfixes 2008-04-06 Carlo Baldassi * Added 16 bit support 2008-02-25 Carlo Baldassi * Added left-right switches 2008-02-20 Carlo Baldassi * Added rigidity mask 2007-12-07 Carlo Baldassi * initial revision. liblqr-1-0.4.1/INSTALL0000644000175000017500000002243210722735022011114 00000000000000Installation Instructions ************************* Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free Software Foundation, Inc. This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Here is a another example: /bin/bash ./configure CONFIG_SHELL=/bin/bash Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent configuration-related scripts to be executed by `/bin/bash'. `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. liblqr-1-0.4.1/NEWS0000644000175000017500000000316411201667723010570 00000000000000Version 0.4: * New features: * Support for image types (color models): GREY, GREYA, RGB, RGBA, CMY, CMYK, CMYKA and custom * Additional builtin energy functions based on luma instead of brightness * Support for custom energy functions * Functions to read out the energy map * Cancel function to interrupt computations * Additional methods for bias and rigidity masks * Use a single progress instead of several ones when the update is performed in steps * Can handle input buffers non-destructively * Performace related: * Faster rescaling thanks to optimisations in the code * Spare memory when not using features (e.g. the bias) * Configuration * The default installation directory is now /usr instead of /usr/local * Compiling under MinGW now correctly produces a DLL with the default settings * Now it also compiles under MS Visual C++ * All public macro names start with LQR_* (old versions are still available but can be disabled at configure time) Version 0.3: * New features: * Enlargement is not limited to 200% any more (it is automatically performed in steps) * Added readout functions for the internal visibility map Version 0.2: * New fetures: * Support for 16-bit, 32-bit and 64-bit per channel images * Rigidity masks * Left-right/top-bottom balance * Performace related: * Improved attached visibility maps management (lower memory requirements) * All internal buffers turned from double to float, improving both speed and memory requirements * Documentation: * Reviewed manual and completed refence * Added man pages liblqr-1-0.4.1/TODO0000644000175000017500000000004111163516123010542 00000000000000* use babl library * exceptions? liblqr-1-0.4.1/config.guess0000755000175000017500000012753411202133707012410 00000000000000#! /bin/sh # Attempt to guess a canonical system name. # Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, # 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 # Free Software Foundation, Inc. timestamp='2008-01-23' # This file is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

With the default options, the `configure' sctipt produces a DLL. If you want to build a static library, you should pass the options --disable-shared and --disable-declspec to `configure', and make sure you define the preprocessor LQR_DISABLE_DECLSPEC whenever you want to compile/link against the static library. 2) Using MS Visual C++ The library compiles at least under `Microsoft Visual C++ 2008 Express edition'. You can create an empty DLL project with the default setup (choose Console Application then Advanced Settings -> DLL + Empty Project), then put the `lqr' directory in the project directory and add all of the files within that dir to the project with `Add Exisitng Item'. Then, you must modify the project properties like this: a) C/C++ -> General -> Additional Include Directories: add the directory `lqr' and its parent, and also the directory where all the necessary glib-2.0 headers are found. b) C/C++ -> Preprocessor -> Preprocessor Definitions: add LQR_EXPORT to the list c) C/C++ -> Advanced -> Compile As: Compile as C Code (it also works otherwise, but this option seems to make sense given that the library is ANSI C) d) Linker -> General -> Version: set version (don't know if this is really needed or has any purpose at all though) e) Linker -> Additional Library Directories: add the directory where glib-2.0.lib is found f) Linker -> Input -> Additional Dependencies: add glib-2.0.lib When you build the project, it should produce the library liblqr-1-0.lib and liblqr-1-0.dll files (assuming your project is called `liblqr-1-0'). liblqr-1-0.4.1/autogen.sh0000755000175000017500000001125611201664540012065 00000000000000#!/bin/sh # This script does all the magic calls to automake/autoconf and # friends that are needed to configure a cvs checkout.

\fIbuffer\fR, in a format suitable for plotting: all values are in the range between 0 and 1, and the true values are mapped nonlinearly and stretched on this whole range, so that the differences between the middle values are enhanced with respect to very high or very low values\&. .PP The \fIorientation\fR parameter must be either 0 to get the energy map used for horizontal scalings, or 1 to get the map for vertical scalings\&. .PP The buffer must be allocated by the user before calling this function, and its size must be at least \fIwidth\fR * \fIheight\fR, where \fIwidth\fR and \fIheight\fR are the current width and height of the \fIcarver\fR\&. The energy values are ordered by row first, then by column\&. .PP The outcome will include the effect of the bias added to the \fIcarver\fR, if any\&. .PP This function can be called over non\-initialised LqrCarver objects, e\&.g\&. to provide previews on the effect of different energy functions, but it can also be invoked at any later time\&. Note, however, that in this latter case the \fIcarver\fR could be flattened if necessary, therefore the function invocation is potentially destructive of the internal visibiliy map\&. .PP The function \fBlqr_carvet_get_true_energy\fR is identical to the previous one, but the resulting buffer will contain the true energy, not scaled nor shifted\&. .PP The function \fBlqr_carver_get_energy_image\fR is very similar to the function \fBlqr_carveR_get_energy\fR, but it can be used to fill directly an image buffer of the format specified through the additional parameters \fIcol_depth\fR and \fIimage_type\fR (see \fBLqrColDepth\fR(3) and \fBLqrImageType\fR(3))\&. The \fIbuffer\fR must be passed as \fBvoid*\fR, but it must point to a memory area with sufficient allocated space for the chosen image type and colour depth\&. The image type cannot be LQR_CUSTOM_IMAGE\&. .PP For any choice of the parameters describing the image, the resulting \fIbuffer\fR will hold a greyscale image, ranging from black (lowest energy) to white (highest energy)\&. The opacity (alpha) will be set to 1, if present\&. All the information will be stored in the black channel in LQR_CMYK_IMAGE and LQR_CMYKA_IMAGE image types\&. .SH "RETURN VALUES" .PP The return values follow the Liquid Rescale library signalling system\&.

If a visibility map was loaded through the function \fBlqr_vmap_load\fR, and the carver was not initialised, the resizing operations must be limited to the direction and the sizes included in the loaded map\&.

In case it isn\'t, the function returns almost immediately, otherwise operations will proceed following the order given through the function \fBlqr_carver_set_resize_order\fR\&. Currently, on\-the\-fly rescaling without computation is only possible for a single direction at a time\&. .PP If the new size (in one direction or in both) is greater than or equal to the original size multiplied by the enlargement step of the \fIcarver\fR object (as obtained through \fBlqr_carver_get_enl_step\fR(3)), the rescaling will be performed in multiple steps\&. At each step, the original size stored internally is reset to the new value; therefore, each step in the process can be bigger then the previous one\&. .PP Whenever the resizing dirction changes (this may happen in a single call of the rescaling function or through multiple calls), or if performing a multiple steps enlargement as per the previous paragraph, the visibility map computed during the first direction rescale is dropped to make place for the one for the second (and the original size of the image is reset to the current value)\&.

The rigidity mask area can exceed the boundary of the image, and the offsets can be negative\&. .PP The values in the given \fIbuffer\fR are scaled by the overall \fIrigidity\fR value set when calling the function \fBlqr_carver_init\fR\&. .PP The function \fBlqr_carver_rigmask_add\fR can be used when the area to add is of the same size of the image loaded in the LqrCarver object and the offsets are 0\&. .SH "SETTING THE RIGIDITY MASK FROM AN IMAGE" .PP The functions \fBlqr_carver_rigmask_add_rgb_area\fR and \fBlqr_carver_rigmask_add_rgb\fR are very similar to \fBlqr_carver_rigmask_add_area\fR and \fBlqr_carver_rigmask_add\fR, but use 8\-bit multi\-channel images as inputs\&. .PP The number of channels in the image is passed via the parameter \fIchannels\fR\&.

It can be used to convert saved data in a format which can be loaded in an LqrCarver object\&. .PP The parameter \fIbuffer\fR must point to an an array of \fIwidth\fR * \fIheight\fR \fBint\fRs holding the visibility information\&. .PP The parameter \fIdepth\fR represents the maximum possible amount of rescaling with the given map\&. .PP The parameter \fIorientation\fR must be 0 if the map is to be used for horizontal rescaling, 1 if it is to be used for vertical rescaling\&. .SH "VISIBILITY MAPS FORMAT" .PP The \fIbuffer\fR must be an array of integers of size \fIwidth\fR * \fIheight\fR\&. For an horizontally oriented visibility map, the format is as such: each row must contain all values between 1 and \fIdepth\fR (included) exactly once, with low values indicating the pixels which will be operated on first during rescaling\&. All other pixels must be 0, which means that they won\'t be affected by rescaling\&.
