[This is the first released version of the library GPL. It is numbered 2 because it goes with version 2 of the ordinary GPL.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Library General Public License, applies to some specially designated Free Software Foundation software, and to any other libraries whose authors decide to use it. You can use it for your libraries, 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 this service 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 make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library, or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link a program with the library, you must provide complete object files to the recipients so that they can relink them with the library, after making changes to the library and recompiling it. And you must show them these terms so they know their rights. Our method of protecting your rights has two steps: (1) copyright the library, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the library. Also, for each distributor's protection, we want to make certain that everyone understands that there is no warranty for this free library. If the library is modified by someone else and passed on, we want its recipients to know that what they have is not the original version, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that companies distributing free software will individually obtain patent licenses, thus in effect transforming the program into proprietary software. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License, which was designed for utility programs. This license, the GNU Library General Public License, applies to certain designated libraries. This license is quite different from the ordinary one; be sure to read it in full, and don't assume that anything in it is the same as in the ordinary license. The reason we have a separate public license for some libraries is that they blur the distinction we usually make between modifying or adding to a program and simply using it. Linking a program with a library, without changing the library, is in some sense simply using the library, and is analogous to running a utility program or application program. However, in a textual and legal sense, the linked executable is a combined work, a derivative of the original library, and the ordinary General Public License treats it as such. Because of this blurred distinction, using the ordinary General Public License for libraries did not effectively promote software sharing, because most developers did not use the libraries. We concluded that weaker conditions might promote sharing better. However, unrestricted linking of non-free programs would deprive the users of those programs of all benefit from the free status of the libraries themselves. This Library General Public License is intended to permit developers of non-free programs to use free libraries, while preserving your freedom as a user of such programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as regards changes in header files, but we have achieved it as regards changes in the actual functions of the Library.) The hope is that this will lead to faster development of free libraries. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, while the latter only works together with the library. Note that it is possible for a library to be covered by the ordinary General Public License rather than by this special one. GNU LIBRARY GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Library General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also compile or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. c) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. d) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. 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 not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Library 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 specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "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 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY 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 LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Patch from Goetz Waschk and Laurent Montel. 2007-02-28 Kjartan Maraas configure.in: Release 2.3.19 2007-02-28 Kjartan Maraas * configure.in: Fix a typo introduced with the bug fix for bug #131478.

Patch from Christian Persch. Closes bug #131478 2005-10-26 Alexander Larsson * Makefile.am: * configure.in: Cygwin build fixes from Cygwin Ports maintainer (#317562) 2005-10-05 Dom Lachowicz * art-misc.[ch]: Turn memory-managing macros into proper functions instead of preprocessor wrappers around malloc. Win32 ships multiple runtimes, and an art_alloc'd block from one runtime can't be art_free'd by a different runtime. * libart.def: Export the 3 new functions 2005-05-27 Alexander Larsson * art_vpath_bpath.c: (art_vpath_render_bez): Handle the case where start and endpoint are very near in a better way. (#301750) Patch from Bernhard Herzog 2005-03-24 Tor Lillqvist * art_misc.h (ART_GNUC_PRINTF, ART_GNUC_NORETURN): Use __format__, __printf__ and __noreturn__ to avoid warnings in case "format", "printf" or "noreturn" are #defined to something else. For example GNU libintl.h (at least some versions of it) #defines printf as libintl_printf. 2005-01-24 Kjartan Maraas * art_render_gradient.c: (art_render_gradient_radial_render): * testart.c: * testuta.c: (main): Fix some compiler warnings etc. 2005-01-21 Kjartan Maraas * Release 2.3.17 2004-03-22 Michael Meeks * Makefile.am (EXTRA_DIST): add libart.def. 2004-03-04 Glynn Foster * Makefile.am, configure.in, libart-2.0-uninstalled.pc.in: Add uninstalled pkg-config file. Tue Sep 09 16:30:31 2003 George Lebl * Release 2.3.16 * art_render_gradient.c: revert the double comparison test in the asserts and comment out the two asserts causing crashes everywhere, see bug #121850 2003-09-02 Alexander Larsson * configure.in: 2.3.15 2003-08-26 Morten Welinder * art_render_gradient.c (art_render_gradient_linear_render_8): Fix vertical gradients. Fix yet more floating point comparisons using !=. For the record, Gnumeric is a heavy user. 2003-08-14 Tor Lillqvist Some nitpicking changes for Win32: * libart-features.h.in: Declare the variables from the library as dlimport/dllexport on Win32. * Makefile.am: Don't use -lm on Win32. Use the libart.def file. * makefile.msc: Update to generate same name DLL and import library as auto* and libtool. Add missing objects. (But dunno if it is useful to maintain this file. It isn't distributed in the source tarballs (should it be?). And, if it were distributed, and the intention was to support random people really building libart with MSVC, one should distribute also prebuilt config.h(.win32) and libart-features.h(.win32) files.) * libart-zip.in (DEVZIP): Fix typo. (DLLDIR): libtool 1.5 installs DLLs in $(prefix)/bin, so look there, too. * libart.def: Add missing entry points. * testuta.c: To check that the export/import of the version variables work, print out them in a comment. Undefine LIBART_COMPILATION before including libart-features.h. 2003-08-08 Alexander Larsson * configure.in: 2.3.14 Fri Jul 25 12:29:35 2003 George Lebl * art_render_gradient.c (art_render_gradient_linear_render_8) (art_render_gradient_linear_render) (art_render_gradient_linear) (art_render_gradient_radial_render) (art_render_gradient_radial): Redo the checks where float was compared by == or != to using the EPSILON define. Also copy the ArtGradientLinear and ArtGradientRadial into the source structure, pretending that these are constants that will never change or be freed by the caller is utterly evil and in fact for librsvg it is not constant. This fixes some more very random crashes when using librsvg with libart (which seems to be the only usage of the gradient stuff) Fri Jul 18 12:57:36 2003 George Lebl * art_render_gradient.c: Fix more comparison-of-doubles by == bugs, this code is uber ugly. Should fix the fairly random crashes on asserts I've been having. 2003-07-11 Michael Meeks * Version 2.3.13 2003-07-11 Federico Mena Quintero * art_svp_ops.c (art_svp_minus): impl. Tue Jul 08 01:15:02 2003 George Lebl * art_render_gradient.c: fix comment as pointed out by alex Tue Jul 08 01:13:48 2003 George Lebl * art_render_gradient.c (art_render_gradient_linear_render_8): when we wish to find the current segment and we go beyond the last stop due to float fun, use the last segment as that's really what we want. Avoids a very abrupt assert death. 2003-05-05 Alexander Larsson * configure.in: Bump to 2.3.12 2003-04-24 Alexander Larsson * art_uta_vpath.c (art_uta_from_vpath): Don't silently stomp on memory on bad vpaths. 2003-04-11 Alexander Larsson * art_svp_vpath_stroke.c (render_seg): Handle cases when dmr2 is very small better. 2003-04-10 Alexander Larsson * art_svp_wind.c (x_order_2): Handle horizontally aligned segments. 2002-11-25 Alexander Larsson * configure.in: Bump to 2.3.11 2002-10-16 John Harper * art_render_svp.c (art_render_svp_callback, art_render_svp_callback_span, art_render_svp_callback_opacity, art_render_svp_callback_opacity_span): if no runs would normally be emitted, but start is greater than zero, emit a single run covering the entire width of the rendered region 2002-08-18 Havoc Pennington * autogen.sh: hardcode aclocal-1.4/automake-1.4 so that users with both automake 1.6 and 1.4 installed get the right automake. Means compilation from CVS will now require the latest automake 1.4 release, or manually creating symlinks called "automake-1.4" and "aclocal-1.4" 2002-07-01 Alexander Larsson * Release 2.3.10 2002-07-01 Alexander Larsson * configure.in (LIBART_VERSION_INFO): Bump to 2.3.10 * art_svp_intersect.c (art_svp_intersect_add_seg): Initialize seg->wind_left to zero, this avoids uninitialized memory read later in art_svp_intersect_horiz_commit. 2002-06-24 Alexander Larsson Release 2.3.9. 2002-06-24 Alexander Larsson * configure.in: Bump to 2.3.9 2002-06-04 Balamurali Viswanathan * Makefile.am: Added -lm to libart_lgpl_2_la_LIBADD fixes bug 75711 (Jacob's suggestion) 2002-05-08 Raph Levien * art_uta_vpath.c (art_uta_add_line): Fixes very subtle edge case found by Federico Mena Quintero: (96, 96) - (96.220200017562348, 93.034868598919431). Previously, through numerical error, xn was a hair to the left, throwing off the Bresenham iteration. 2002-03-08 Tor Lillqvist * configure.in: Minor changes for build on Win32. Call AC_LIBTOOL_WIN32_DLL. Set automake conditionals OS_WIN32 and MS_LIB_AVAILABLE. * art_affine.c: Include art_misc.h for M_PI, which not necessarily is in math.h. * Makefile.am: On Win32, build and install import libraries, both for gcc and for MSVC (if available). * libart-zip.in: New file. Used to build runtime and developer package for Win32. 2002-02-06 Laszlo Peter * configure.in: add AC_FUNC_ALLOCA * art_render_gradient.c: copy alloca hacks from glib/galloca.h 2002-02-02 Alexander Larsson * art_render.c: Add special case for art_render_composite_8 for two cases that are very common when rendering SVGs with librsvg. I'm sure these can be optimized further, but i'm feeling very slow today. 2002-02-01 Alex Larsson * art_render_gradient.c: Add optimized case for depth==8, n_channels == 3 * test_gradient.c: Test case for gradients. Uses gtk+, so not built by default. 2002-01-10 Anders Carlsson * Release 2.3.8 2002-01-04 Anders Carlsson * configure.in: Bump version to 2.3.8. 2002-01-03 Darin Adler * Makefile.am: Add art_render_mask.[ch]. * art_bpath.h: * art_rect_svp.h: * art_rect_uta.h: * art_render.h: * art_render_gradient.h: * art_render_mask.h: * art_render_svp.h: * art_rgb_svp.h: * art_svp_intersect.h: * art_svp_ops.h: * art_svp_point.h: * art_svp_render_aa.h: * art_svp_vpath.h: * art_svp_vpath_stroke.h: * art_svp_wind.h: * art_uta.h: * art_uta_rect.h: * art_uta_ops.h: * art_uta_svp.h: * art_uta_vpath.h: * art_vpath_bpath.h: * art_vpath_dash.h: * art_vpath_svp.h: Fix includes so that each header includes what it needs. * art_affine.c: * art_alphagamma.c: * art_bpath.c: * art_gray_svp.c: * art_misc.c: * art_pixbuf.c: * art_rect.c: * art_rect_svp.c: * art_rect_uta.c: * art_render.c: * art_render_gradient.c: * art_render_mask.c: * art_render_svp.c: * art_rgb.c: * art_rgb_a_affine.c: * art_rgb_affine.c: * art_rgb_affine_private.c: * art_rgb_bitmap_affine.c: * art_rgb_pixbuf_affine.c: * art_rgb_rgba_affine.c: * art_rgb_svp.c: * art_rgba.c: * art_svp.c: * art_svp_intersect.c: * art_svp_ops.c: * art_svp_point.c: * art_svp_render_aa.c: * art_svp_vpath.c: * art_svp_vpath_stroke.c: * art_svp_wind.c: * art_uta.c: * art_uta_ops.c: * art_uta_rect.c: * art_uta_svp.c: * art_uta_vpath.c: * art_vpath.c: * art_vpath_bpath.c: * art_vpath_dash.c: * art_vpath_svp.c: Fix order of includes so that the corresponding header is included first, to test that each header includes what it needs. 2002-01-02 Darin Adler * art_alphagamma.h: * art_gray_svp.h: * art_pixbuf.h: * art_render.h: * art_rgb.h: * art_rgba.h: Add some missing includes. 2001-12-26 Raph Levien * art_svp_intersect.c: More fixes to intersector. When tops coincide, full ordering test is performed (with breaking), rather than just comparing b from line eq. Also, had a test for x >= backwards in art_svp_intersect_add_point. Thanks to Bruce Q. Hammond for test cases. 2001-11-21 Raph Levien * art_svp_intersect.c (art_svp_intersect_break): Changed break logic systematically so that new breaks are always in order, rather than allowing them to become out of order, then try to fix them up later. It's no doubt possible to come up with cases in which this reduces precision, but it simplifies life nicely, so I did it. * (art_svp_intersect_horiz): Initialize (a, b, c) values of hs to avoid UMR's when they are tested later. * art_svp_ops.c (print_ps_vpath): Changed the coordinate transform so that it's done in the PostScript rather than the C code that outputs the coordinates. This makes it easier to reconstruct the vector path from the debug output. 2001-11-16 Alex Larsson * art_rect.c (art_drect_svp_union, art_drect_svp): Don't call art_drect_union() in these functions, since it considers zero-width or zero-height svg segments to be empty. This causes it to think i.e. rectangular svps are empty. 2001-11-07 Raph Levien * art_svp_intersect.c (art_svp_intersect_horiz): Fixed important logic bug, failing to test crossings of neighbors when inserting horizontal lines. Also changed printf to art_dprint. * art_misc.c (art_dprint): Added function for debug printing, so verbose intersector output doesn't have to go through printf. * art_misc.h (ART_USE_NEW_INTERSECTOR): I've turned this on now, as the new intersector certainly seems to be performing better than the old one now. 2001-10-31 Anders Carlsson * Release 2.3.7 2001-10-15 Raph Levien * art_svp_intersect.c (art_svp_intersect_horiz): Minor logic fix so that horiz segments successfully cross zero length segments in the active list. (art_svp_intersect_test_cross): Flags indicating whether to do add_point (potentially breaking neighbors) to left and to right. (art_svp_intersect_insert_cross): Provide ART_BREAK_LEFT and ART_BREAK_RIGHT flags to art_svp_intersect_test_cross, depending on direction of search. (art_svp_intersect_advance_cursor): Provide flags (allow both left and right breaking) to test_cross. 2001-10-15 Raph Levien * art_svp_intersect.c (CHEAP_SANITYCHECK): Added an inexpensive sanitycheck to detect multiple insertions of a segment into the horiz list. (art_svp_writer_rewind_add_point): Avoid breaking lines below their bottom point. (art_svp_intersect_test_cross): Handle cases correctly where intersection point matches y0 of left or right segment. These _do_ happen in real world examples. Also, do add_point on newly inserted intersection point. 2001-10-14 Raph Levien * art_svp_intersect.c (art_svp_intersect_add_point): Fixed rather subtle logic bug that misplaced insertion point when seg argument was NULL. 2001-10-11 Raph Levien * art_svp_render_aa.c (art_svp_render_aa_iter_step): Got rid of qsort of steps, and now keep the step list in sorted order. Further, we combine duplicate steps with the same x value, which bounds the size of the step list to x1 - x0, so we don't need to dynamically resize it. Thanks greatly to Bruce Q. Hammond for the original version of this patch. 2001-10-09 Raph Levien * art_svp_intersect.c (art_svp_intersect_test_cross): Breaks bottom part of line segments in "too close" cases. 2001-10-09 Raph Levien * art_svp_intersect.c (art_svp_writer_rewind_add_point): Fixed bbox computation. (art_svp_intersector): Handle degenerate case where input SVP has 0 segments. * art_svp_intersect.h: Moved definition of art_svp_intersector inside #ifdef __cplusplus, so it links properly against C++ 2001-10-09 Raph Levien * art_svp_intersect.c (art_svp_intersect_break): Handle case when break y equals sweep line correctly. Also adds first try at winding number sanitychecker, but that makes too many false positives. 2001-10-07 Raph Levien * art_svp.c (EPSILON): Set to zero if new intersector is in use - we want svp's to be in strict sorted order. * art_svp_intersect.c (art_svp_intersect_test_cross): Explicitly check that top points are equal, and swap immediately if b is out of order. (art_svp_intersect_horiz): Break segments that intersect horizontal lines. Now passes "two squares with offset" test. 2001-10-05 Raph Levien * art_svp_intersect.c: Major changes to accommodate horizontal lines. Intersections of horizontal lines aren't fully processed, but should work a lot better than before. * testart.c: Minor tweaks. testpat now frees memory so it can be run under memprof to detect leaks. 2001-10-03 Raph Levien * art_svp_intersect.c (art_svp_intersect_advance_cursor): Made test_cross for inserted segments common between intersection processing and cursor advance, and also took care of a case that hadn't been handled before. Also added invariant sanitychecker for debugging purposes. 2001-10-02 Raph Levien * art_svp_ops.c: ART_USE_NEW_INTERSECTOR variants of svp ops changed to do shallow free of merged svp. 2001-10-01 Raph Levien * art_svp_intersect.c: * art_svp_intersect.h: * Makefile.am: * art_misc.h: * art_svp_wind.h: First commit of new intersector code. It is turned off by default, but can be enabled by #defining ART_USE_NEW_INTERSECTOR in art_misc.h. * art_svp_ops.c: Make svp ops use new intersector if enabled. * art_svp_vpath_stroke.c: Make vpath stroking use new intersector if enabled. * testart.c: New test case for intersector. Wed Sep 26 03:48:13 2001 George Lebl * Release 2.3.6 Wed Sep 26 03:11:40 2001 George Lebl * gen_art_config.c: Fix 64bit issues, cast sizeof return when using %d to print it. 2001-09-13 Havoc Pennington * Makefile.am: rename library to libart_lgpl_2 * libart-2.0.pc.in (Cflags): move includes * libart-config.in: move includes * Makefile.am: delete libartConf.sh, rename libart-config (EXTRA_DIST): don't install m4 files (libart_lgplincdir): move headers 2001-08-03 Michael Meeks * Version 2.3.5 for the API freeze. 2001-07-12 Darin Adler * art_affine.c: (art_affine_expansion): Fix handling of negative numbers. We ran into this bug a while back when figuring out why librsvg couldn't handle certain svg files. 2001-07-12 Darin Adler * art_misc.h: Change art_expand macro so it's a single statement, using the do while (0) trick, which gets rid of some warnings. * art_pixbuf.c: Add a missing include. * art_vpath_svp.c: (art_vpath_from_svp): Initialize a variable to avoid a compiler warning. * gen_art_config.c: Add a missing include. 2001-03-24 Martin Baulig Applied the patch from Alexander Larsson which was sitting in gnome-libs/patches/libart.diff since February. [FIXME: Alex, can you please provide a ChangeLog?]) * art_rgb_a_affine.[ch]: New files. 2001-01-07 Hans Breuer * art_misc.c : embryonic change to use libart_lgpl on win32 * libart.def : new file, exported functions for win32 dll * makefile.msc : handwritten for MSVC compiler 2000-09-30 Martin Baulig * libart-2.0.pc.in: Provide pkg-config script. * configure.in: Create libart-2.0.pc from libart-2.0.pc.in. * Makefile.am (pkgconfig_DATA): Install the libart-2.0.pc script in `$(libdir)/pkgconfig'. 2000-08-15 Raph Levien * art_render.c (art_render_image_solid_negotiate): Only sets ART_IMAGE_SOURCE_CAN_COMPOSITE when a compositing callback is selected. Previously was causing segfaults on non-alpha images. Thanks to Leonard Rosenthol for spotting the bug. Fri Jun 30 22:56:58 2000 Raph Levien * art_render.c (art_render_composite): Fixed a bug that caused it to ignore the alpha setting. Also art_render_composite_8(). 2000-06-01 John Sullivan * art_svp_render_aa.c: (art_svp_render_aa_iter_step): Made it build by correcting struct member name from Raph's previous checkin. Wed May 31 11:10:58 2000 Raph Levien * art_svp_render_aa.c (art_svp_render_aa_iter_step): Updated n_steps_max in iter structure after steps reallocation. Tue May 30 10:33:13 2000 Raph Levien * art_svp_render_aa.c (art_svp_render_aa_iter_step): Fixed not updating iter->steps when steps gets reallocated. 2000-05-30 Pavel Cisler * art_rgba.c: Make it build -- fix a broken include. Tue May 30 00:09:21 2000 Raph Levien * art_render_gradient.c (art_render_gradient_setpix): Fixed an off-by-one loop error. Mon May 29 15:00:39 2000 Raph Levien * Makefile.am: Moved relevant .h files into HEADERS stanza. Mon May 29 13:48:49 2000 Raph Levien This is a fairly major commit, as it adds both the new, modular rendering architecture and gradients. Quite a bit of the code feels like "reference code" now, in that it is (hopefully) correct, but not necessarily very fast. In addition, there remain a few things not done, including the use of SVP's as non-driver mask sources. AlphaGamma and filter level also remain unimplemented. No compositing modes other than ART_NORMAL are implemented. All in good time! * configure.in: added -Wmissing-prototypes flag. Bumped version number to 2.3.0. * art_render.h: * art_render.c: Added new rendering architecture. * art_render_svp.h: * art_render_svp.c: Added renderers to use SVP's as mask sources in new rendering architecture. * art_render_gradient.h: * art_render_gradient.c: Added linear and radial gradients as image sources in new rendering architecture. * art_rgba.h: * art_rgba.c: Added functions for manipulating and compositing RGBA pixels. * art_svp_wind.c: Added static to trap_epsilon(), #ifdef'd out traverse(). * art_uta_ops.c: Added #include "art_uta_ops.h". * art_uta_rect.c: Added #include "art_uta_rect.h". * art_uta_svp.h: fixed __ART_UTA_SVP_H__ name. * art_misc.h: Added ART_GNUC_NORETURN attribute, added that to the prototype for art_die(). Added "static" to function declarations to avoid warnings when compiled with * testart.c: Added gradient test. Thu May 25 23:30:39 2000 Raph Levien * art_svp_render_aa.h: * art_svp_render_aa.c: Added art_svp_render_aa_iter functions, suitable for iterative rendering of an svp, one scan line at a time. * configure.in: Bumped version to 2.2.0. Tue May 16 15:03:35 2000 Raph Levien * art_rgb_pixbuf_affine.c: Included corresponding .h file. * art_rgb_pixbuf_affine.h: Put recursive #includes inside LIBART_COMPILATION test. * art_gray_svp.c: * art_rgb_svp.c: Explicit casts for callback data. Also removed "render the steps into tmpbuf" comment. * gen_art_config.c: * Makefile.am: * configure.in: Added code to automatically generate an art_config.h file, to be installed in libart's include dir. This file defines ART_SIZEOF_{CHAR,SHORT,INT,LONG} and art_u{8,16,32}. * art_misc.h: Moved definition of art_u8 and art_u32 into art_config.h. Added GCC printf format attributes. * art_svp_wind.c (traverse): Fixed UMR bug here. The function isn't actually used, so it's just for cleanliness. 2000-04-18 Lauris Kaplinski * art_affine.c (art_affine_to_string): Replaced snprinf with art_ftoa to avoid localisation of generated numbers 2000-04-18 ERDI Gergo * art_rgb_pixbuf_affine.h: Included the ArtPixBuf declaration Fri Apr 14 16:33:55 2000 Raph Levien * art_svp_wind.c (art_svp_uncross, art_svp_rewind_uncrossed): Fixed uninitialized memory reads when inserting new segment into active_segs. * art_bpath.c (art_bpath_affine_transform): Made it avoid potential uninitialized memory reads when not all the coordinates are needed. Thanks to Morten Welinder for spotting both of these problems. 2000-04-05 Raph Levien * art_svp_wind.c: Make "colinear" warnings go to stderr instead of stdout. Of course, when I finish the new intersector, these will go away entirely. 2000-04-04 Raph Levien * art_uta_vpath.c (art_uta_add_line): Fixed bug that was causing segfaults on alphas. Thanks to msw for localizing it. 2000-01-17 Raph Levien * art_svp_vpath_stroke.c (art_svp_vpath_stroke): Typo in api header (thanks rak). 2000-01-16 Timur Bakeyev * autoconf.sh: Instead of jumping between srdir and builddir just process all the auto* staff in srcdir. In fact, just saying the same things in other words. 2000-01-10 Elliot Lee * Makefile.am, *.h: Add rather bad hacks to the header files to allow compilation * Makefile.am: Distribute libart-config.in 2000-01-09 Raph Levien art_rgb_pixbuf_affine.c, art_rgb_rgba_affine.c, art_rgb_svp.c, art_svp.c, art_svp_ops.c, art_svp_point.c, art_svp_render_aa.c, art_svp_vpath.c, art_svp_vpath_stroke.c, art_svp_wind.c, art_uta.c, art_uta_ops.c, art_uta_rect.c, art_uta_svp.c, art_uta_vpath.c, art_vpath.c, art_vpath_bpath.c, art_vpath_dash.c, art_vpath_svp.c: Added API documentation. Fri Sep 24 17:53:21 1999 Raph Levien * art_svp_render_aa.c (art_svp_render_insert_active): Avoid reading undefined memory (thanks to Morten Welinder). 1999-09-19 Raph Levien * art_pixbuf.c (art_pixbuf_duplicate): Added a duplicate function at the request of Michael Meeks. 1999-09-11 Raph Levien * art_affine.c (art_affine_to_string): Tightened the predicate for matching rotate-only affines, which was too weak. Thanks to lewing for spotting it! 1999-09-01 Raph Levien * art_affine.c, art_alphagamma.c, art_bpath.c, art_gray_svp.c, art_misc.c, art_pixbuf.c, art_rect.c, art_rect_svp.c, art_rect_uta.c, art_rgb.c, art_rgb_affine.c, art_rgb_bitmap_affine.c: Updates to api doc headers. 1999-08-24 Raph Levien * art_affine.c, art_alphagamma.c, art_alphagamma.h, art_bpath.c, art_bpath.h, art_gray_svp.c, art_misc.c, art_pixbuf.c, art_pixbuf.h, art_point.h, art_rect.c, art_rect.h: Added api documentation headers. * testart.c: Added "dash" test, for testing the vpath_dash functions. * art_rgb_pixbuf_affine.h: Fixed the #ifdef for conditional inclusion. Thanks to Kristian Hogsberg Kristensen for spotting the bug. 1999-08-24 Raph Levien * art_svp_render_aa.c (art_svp_render_aa): Added some tests to avoid NaN for infinite slopes, which were causing problems on Alphas. Closes bug #1966. 1999-08-20 Federico Mena Quintero * configure.in: Fixed library's libtool version number. 1999-08-03 Larry Ewing * art_vpath_dash.c (art_vpath_dash): fix a bug/typo that was causing certain paths to loop infinitely. 1999-07-28 Raph Levien * art_vpath_dash.[ch]: Added a function to add a dash style to vpaths. It is tested, but has a couple of rough edges (see code for details). * testart.c: added tests for the new vpath_dash functionality. * Makefile.am: added art_vpath_dash.[ch] files. 1999-07-26 Raph Levien * art_rgb.c (art_rgb_fill_run): fixed incorrect test for big-endianness. Thanks to Michael Zucchi for spotting it. Fri Jul 16 23:42:59 1999 Tim Janik * art_affine.c (art_affine_flip): flip translation matrixes as well, by inverting matrix[4] if (horz) and inverting matrix[5] if (vert). Fri Jul 16 23:03:26 1999 Tim Janik * art_pixbuf.[hc]: deprecated art_pixbuf_free_shallow(), people should always free pixbufs with art_pixbuf_free() and use the _dnotify variants for specific destruction behaviour. added art_pixbuf_new_rgb_dnotify() and art_pixbuf_new_rgba_dnotify() which allow for a destruction notification function. (this involved adding two extra pointers to the ArtPixBuf structure, and removal of the recently introduced int flags field). Mon Jul 12 01:13:23 1999 Tim Janik * art_affine.[hc]: added art_affine_equal(), which checks two matrixes for equality within grid alignment. Fri Jul 9 17:50:19 1999 Tim Janik * art_affine.[hc]: added art_affine_flip() to flip a matrix horizontally and/or vertically, or just copy it. added art_affine_shear() to setup a shearing matrix. Tue Jul 6 19:03:39 1999 Tim Janik * art_pixbuf.h: added an int flags; member to the end of the structure, it currently only holds information about whether the pixels member should be freed. (raph: i think flags is more generic than free_pixels, so we can reuse that field if further demands popup in the future). * art_pixbuf.c: (art_pixbuf_new_const_rgba): (art_pixbuf_new_const_rgb): new functions that prevent the pixels member from being freed upon art_pixbuf_free (). (art_pixbuf_free): only free the pixels member if it is non-NULL and the PIXBUF_FLAG_DESTROY_PIXELS is set. 1999-07-02 Raph Levien * art_vpath_bpath.c (art_vpath_render_bez): Bad bad uninitialized variables. * configure.in: added compile warnings. Guess why :) 1999-06-28 Raph Levien * art_svp_point.h: * art_svp_point.c: Added methods for insideness and distance testing, very useful for ::point methods in canvas items. * testart.c: test code to exercise the art_svp_point functions. * Makefile.am: Additional entries for art_svp_point. 1999-06-28 Raph Levien * art_svp_render_aa.c (art_svp_render_aa): Subtle boundary case in realloc code -- was causing nasty segfaults. Wed Jun 23 15:05:43 1999 Raph Levien * art_rgb_svp.c (art_rgb_svp_alpha_opaque_callback): Missed a case in the anti-segfault crusade. Thanks lewing! Wed Jun 23 11:16:42 1999 Raph Levien * art_rgb_svp.c: Made these routines so they won't segfault even if alpha is out of range. Of course, that begs the question of fixing the render routines so they won't _make_ alpha go out of range, but all in good time. Fri Jun 18 17:32:34 1999 Raph Levien * art_vpath_bpath.c (art_bez_path_to_vec): Switched to a new adaptive subdivision algorithm, which (finally!) takes flatness into account. This should result in both smoother curves and faster operation. Sun Jun 13 21:07:20 1999 Raph Levien * art_svp_wind.c (art_svp_rewind_uncrossed): Made the winding rule logic even more correct :). I somehow missed the fact that a clockwise path should be given a winding number of zero; last night's commit tried to make it -1 (which worked for the test cases I was using). Sun Jun 13 01:23:14 1999 Raph Levien * art_svp_wind.c (art_svp_rewind_uncrossed): Change to winding rule logic so that it correctly handles the case where the leftmost segment is negative. * Makefile.am (libart_lgplinc_HEADERS): made art_svp_wind.h a public headerfile. This is needed for the bpath canvas item. I'm not sure this is the correct way to do it, but it will do for now. * art_vpath_bpath.h: * art_vpath_bpath.c (art_bez_path_to_vec): Added const to arg. * art_vpath_bpath.h: Embarrassing typo. * art_bpath.h: Minor tweaks to the #include paths. It is now consistent with the other header files. Wed Jun 9 20:24:45 1999 Raph Levien * art_svp_vpath_stroke.c: Added all remaining line join and cap types, including round, which takes flatness into account. Several new internal functions (art_svp_vpath_stroke_arc) and added flatness argument to a few internal functions. I might want to change the BEVEL join type to MITER for very small turn angles (i.e. within a flatness threshold) for efficiency. * art_misc.h: Added M_SQRT2 constant. Wed Jun 2 21:56:30 1999 Raph Levien * art_svp_vpath_stroke.c (art_svp_vpath_stroke_raw): Made the closed path detection capable of PostScript semantics (i.e. it now senses the difference between ART_MOVETO and ART_MOVETO_OPEN). * art_svp_vpath_stroke.c (art_svp_vpath_stroke_raw): it now filters out successive points that are (nearly) coincident. This fixes some of the crashes and hangs, including Tim Janik's singularity (trying to stroke MOVETO 50, 50; LINETO 50, 50; END). * art_svp_wind.c (art_svp_rewind_uncrossed): added a test to correctly handle empty input svp's. * art_svp_wind.c (art_svp_uncross): added a test to correctly handle empty input svp's. Sun Jan 17 20:53:40 1999 Jeff Garzik * art_affine.c: Include string.h for memcpy. * art_svp_vpath.c: Remove conflicting static func definition. * art_uta_svp.c: Include art_vpath_svp.h for func definition. Mon Jan 4 12:47:47 1999 Raph Levien * art_bpath.c (art_bpath_affine_transform): Stupid misnaming of this function (forgot the "art_"). Thu Dec 31 09:04:23 1998 Raph Levien * art_affine.c (art_affine_rectilinear): Added this function. * art_rect.c (art_drect_affine_transform): Corrected the name (it was right in the .h). Also made it work with non-rectilinear transforms, while I was at it. Thu Dec 17 11:58:24 1998 Raph Levien * art_alphagamma.h: * art_alphagamma.c: The real code for alphagamma. Wed Dec 16 14:18:46 1998 Raph Levien * art_alphagamma.h: * art_alphagamma.c: Added. At present, it only contains a dummy stub. When the real code is added, it supports doing alpha compositing in a gamma-corrected color space (suppressing jaggies). * art_pixbuf.h: * art_pixbuf.c: Added. This is a virtualization layer over a few different kinds of image formats. * art_rgb_pixbuf_affine.h: * art_rgb_pixbuf_affine.c: Added. Supports compositing of generic images over an rgb buffer. * art_affine.h: * art_affine.c (art_affine_expansion): Added this function, which reports the exact scale factor in the case of rotation, scaling, and transformation (an approximate number in the case of shearing or anamorphic distortion). * art_misc.h: * art_misc.c (art_warn): Added. * art_rgb_affine.h: * art_rgb_affine.c: Added alphagamma argument (not yet implemented). * art_rgb_affine_private.c: Fixed typo bug that was causing repaint problems for nonsquare images. * art_rgb_bitmap_affine.h: * art_rgb_bitmap_affine.c: Major speed improvement, probably fixed correctness while I was at it. Added alphagamma argument (not yet implemented). * art_rgb_svp.h: * art_rgb_svp.c: Added alphagamma argument (only implemented in aa case, not yet alpha case). * art_vpath.c: increased perturbation to 2e-3, because the old value (1e-6) was too small. * testart.c: added alphagamma. * Makefile.am: added new files Sun Dec 27 21:45:03 1998 Raph Levien * art_rect.h: * art_rect.c: Added DRect versions of the basic ops (double rather than int). * art_rect_svp.h: * art_rect_svp.c: Added. This computes the bounding box of an svp. Wed Dec 16 14:18:46 1998 Raph Levien * art_alphagamma.h: * art_alphagamma.c: Added. At present, it only contains a dummy stub. When the real code is added, it supports doing alpha compositing in a gamma-corrected color space (suppressing jaggies). * art_pixbuf.h: * art_pixbuf.c: Added.

Added alphagamma argument (not yet implemented). * art_rgb_svp.h: * art_rgb_svp.c: Added alphagamma argument (only implemented in aa case, not yet alpha case). * art_vpath.c: increased perturbation to 2e-3, because the old value (1e-6) was too small. * testart.c: added alphagamma. * Makefile.am: added new files Mon Dec 14 00:16:53 1998 Raph Levien * art_affine.c (art_affine_to_string): re-added the "scale" method that was accidentally deleted before check-in. * Makefile.am: added new files Sun Dec 13 00:52:39 1998 Raph Levien * art_affine.h: * art_affine.c: Added. Everything you ever wanted to do with an affine transform. Especially check the functions that generate concise PostScript strings for affine transforms. * art_filterlevel.h: A simple enum for selecting filtering style. * art_rgb_affine.h: * art_rgb_affine.c (art_rgb_affine): Added. This function composites an (opaque) rgb image over an rgb pixel buffer. At present, it's slow and only nearest neighbor filtering is enabled. * art_rgb_rgba_affine.h: * art_rgb_rgba_affine.c: Analogous, but for compositing rgba images. * art_rgb_bitmap_affine.h: * art_rgb_bitmap_affine.c: Analogous, but for compositing bitmap images. * art_rgb_affine_private.c (art_rgb_affine_run): Added. This is a common function used by all the rgb_affine modules to move testing for source image bbox out of the inner loop. * Makefile.am: added the new files * testart.c: exercise the image compositors Wed Dec 9 23:36:35 1998 Raph Levien * art_vpath.c (art_vpath_perturb): Made it deal correctly with closed paths (the MOVETO and closing LINETO have to agree). * art_svp_wind.c: Made the bbox calculations for the resulting svp's correct. * art_svp.h: * art_svp.c: The art_svp_seg_compare function moved here, because it's required in art_svp_ops. * art_svp.c (art_svp_add_segment): It now does bbox calculations. * art_svp_ops.h: * art_svp_ops.c: Added. Populated with basic union, intersection, and diff functions. * art_vpath_svp.h: * art_vpath_svp.c: Added. Populated with a function to convert from sorted to unsorted vector paths * Makefile.am: added the new files * testart.c: exercise the stroke outline and vector path operations. 1998-12-08 Herbert Valerio Riedel * art_svp_wind.c: added #include for memcpy() Sun Dec 6 22:15:12 1998 Raph Levien * art_svp_wind.[ch], art_svp_vpath_stroke.[ch]: Added, but it doesn't work yet. These will do stroke outline and basic vector ops like union, intersect, etc. * art_svp_render_aa.c: Added a simple speedup based on bbox culling. I will want to do more speedups, but none of this is necessary for the freeze. * art_svp_vpath.c: Fixed some bugs in the art_svp_from_vpath in cases where there is more than one subpath. * art_vpath.h: * art_vpath.c (art_vpath_perturb): Added this function. This will help cheat as long as the basic vector ops have numerical stability problems. Fri Dec 4 18:00:38 1998 Raph Levien * art_svp_render_aa.c (art_svp_render_aa): Changed the api slightly, to guarantee that the steps are all within the range from x0 (inclusive) to x1 (exclusive). * art_gray_svp.c, art_gray_svp.h: Added. Populated with functions to render into a simple graymap. * art_rgb.c, art_rgb.c: Added. Populated with fill_run and run_alpha methods. * art_rgb_svp.c, art_rgb_svp.h: Added. Populated with functions to render into an RGB buffer, and to composite over an RGB buffer. * Makefile.am: added art_gray_svp, art_rgb, and art_rgb_svp. * testart.c: test the color and layered rendering. Mon Nov 30 01:30:25 1998 Raph Levien * testart.c: added vector path rendering stuff. Some of it needs to go out of the test framework and into the module, but the api hasn't settled down entirely yet (in the real code, all x's in the step field are within bounds). * art_svp_render_aa.c, art_svp_render_aa.c.h: added. * art_svp_vpath.c, art_svp_vpath.h: added. * art_pathcode.h: added ART_MOVETO_OPEN (libart uses an ART_MOVETO_OPEN code at the beginning to indicate an open path, while PostScript uses the lack of a closepath at the end). * art_vpath_bpath.c, art_vpath_bpath.h: fixed it up, added flatness arg to api. * Makefile.am: added new source files. Wed Nov 25 17:19:44 1998 Raph Levien * art_svp.h, art_svp.c: added, basic constructors for sorted vector paths. Sun Nov 22 23:21:09 1998 Raph Levien * Makefile.am (libart_lgplincdir): Fixed stupid bug in naming of the variable. Sun Nov 22 21:41:13 1998 Raph Levien * art_uta_vpath.c: moved art_uta_union into art_uta_ops. * art_uta_ops.[ch]: added, populated with art_uta_union. Thu Nov 19 00:19:40 1998 Raph Levien * libartConf.sh.in: added * Makefile.am: added creation of libartConf.sh, added -version-info * configure.in: added LIBART_VERSION_INFO, support for libartConf.sh * libart.m4: updated version history :) Wed Nov 18 18:15:20 1998 Raph Levien * configure.in (LIBART_VERSION): set this, so that libart-config --version now works. Wed Nov 18 16:50:58 1998 Raph Levien * libart.m4: added (just copied from esound) * configure.in, Makefile.am: added support for libart-config * libart-config.in: added (mostly copied from esound) Tue Nov 10 12:43:30 1998 Raph Levien * Getting the library in shape for initial checkin to CVS. libart_lgpl-2.3.21/art_render_svp.c0000644000175000001440000002345411172343645014206 00000000000000/* * art_render_gradient.c: SVP mask source for modular rendering. * * Libart_LGPL - library of basic graphic primitives * Copyright (C) 2000 Raph Levien * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Library General Public * License as published by the Free Software Foundation; either * version 2 of the License, or (at your option) any later version. * * This library 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.

For enlargement, it is equivalent to point-sampling the ideal bilinear-interpolated image. For reduction, it is equivalent to laying down small tiles and integrating over the coverage area. HYPER is the highest quality reconstruction function. It is derived from the hyperbolic filters in Wolberg's "Digital Image Warping," and is formally defined as the hyperbolic-filter sampling the ideal hyperbolic-filter interpolated image (the filter is designed to be idempotent for 1:1 pixel mapping). It is the slowest and highest quality. Note: at this stage of implementation, most filter modes are likely not to be implemented.

This interface uses a callback for the actual pixel rendering. The callback is called y1 - y0 times (once for each scan line). The y coordinate is given as an argument for convenience (it could be stored in the callback's private data and incremented on each call). The rendered polygon is represented in a semi-runlength format: a start value and a sequence of "steps". Each step has an x coordinate and a value delta. The resulting value at position x is equal to the sum of the start value and all step delta values for which the step x coordinate is less than or equal to x. An efficient algorithm will traverse the steps left to right, keeping a running sum. All x coordinates in the steps are guaranteed to be x0 <= x < x1. (This guarantee is a change from the gfonted vpaar renderer, and is designed to simplify the callback). There is now a further guarantee that no two steps will have the same x value. This may allow for further speedup and simplification of renderers. The value 0x8000 represents 0% coverage by the polygon, while 0xff8000 represents 100% coverage. This format is designed so that >> 16 results in a standard 0x00..0xff value range, with nice rounding. Status of this routine: Basic correctness: OK Numerical stability: pretty good, although probably not bulletproof. Speed: Needs more aggressive culling of bounding boxes. Can probably speed up the [x0,x1) clipping of step values. Can do more of the step calculation in fixed point.

It follows roughly the structure of traverse (above), but is obviously quite a bit more complex. Here are a few important data structures: A new sorted vector path (new_svp). For each (active) segment in the original, a list of intersection points. Of course, the original being traversed. The following invariants hold (in addition to the invariants of the traverse procedure). The new sorted vector path lies entirely above the y scan line. The new sorted vector path keeps the nocross invariant. For each active segment, the y scan line crosses the line from the first to the second of the intersection points (where the second point is cursor + 1 if there is only one intersection point). The list of intersection points + the (cursor + 1) point is kept in nondecreasing y order. Of the active segments, none of the lines from first to second intersection point cross the 1st ip..2nd ip line of the left or right neighbor. (However, such a line may cross further intersection points of the neighbors, or segments past the immediate neighbors). Of the active segments, all lines from 1st ip..2nd ip are in strictly increasing x_order (this is very similar to the invariant of the traverse procedure, but is explicitly stated here in terms of ips). (this basically says that nocross holds on the active segments) The combination of the new sorted vector path, the path through all the intersection points to cursor + 1, and [cursor + 1, n_points) covers the same area as the argument. Another important data structure is mapping from original segment number to new segment number. The algorithm is perhaps best understood as advancing the cursors while maintaining these invariants. Here's roughly how it's done. When deleting segments from the active list, those segments are added to the new sorted vector path. In addition, the neighbors may intersect each other, so they are intersection tested (see below). When inserting new segments, they are intersection tested against their neighbors. The top point of the segment becomes the first intersection point. Advancing the cursor is just a bit different from the traverse routine, as the cursor may advance through the intersection points as well. Only when there is a single intersection point in the list does the cursor advance in the original segment. In either case, the new vector is intersection tested against both neighbors. It also causes the vector over which the cursor is advancing to be added to the new svp. Two steps need further clarification: Intersection testing: the 1st ip..2nd ip lines of the neighbors are tested to see if they cross (using intersect_lines). If so, then the intersection point is added to the ip list of both segments, maintaining the invariant that the list of intersection points is nondecreasing in y). Adding vector to new svp: if the new vector shares a top x coordinate with another vector, then it is checked to see whether it is in order. If not, then both segments are "broken," and then restarted. Note: in the case when both segments are in the same order, they may simply be swapped without breaking. For the time being, I'm going to put some of these operations into subroutines. If it turns out to be a performance problem, I could try to reorganize the traverse procedure so that each is only called once, and inline them. But if it's not a performance problem, I'll just keep it this way, because it will probably help to make the code clearer, and I believe this code could use all the clarity it can get. */ /** * art_svp_uncross: Resolve self-intersections of an svp. * @vp: The original svp. * * Finds all the intersections within @vp, and constructs a new svp * with new points added at these intersections. * * This routine needs to be redone from scratch with numerical robustness * in mind.
