13 
14 \section intro_sec Introduction
15 
16 The SDL2_gfx library provides the basic drawing functions such as lines,
17 circles or polygons provided by SDL_gfx on SDL2 against renderers of SDL2.
18 
19 The current components of the SDL2_gfx library are:
20 - Graphic Primitives (SDL2_gfxPrimitives.h, SDL2_gfxPrimitives.c)
21 - Surface Rotozoomer (SDL2_rotozoom.h, SDL2_rotozoom.c)
22 - Framerate control (SDL2_framerate.h, SDL2_framerate.c)
23 - MMX image filters (SDL2_imageFilter.h, SDL2_imageFilter.c)
24 - Build-in 8x8 Font (SDL2_gfxPrimitives_font.h)
25 
26 Note that SDL2_gfx is compatible with SDL version 2.0 (not SDL 1.2).
27 
28 \section install_sec Installation
29 
30 \subsection unix Unix/Linux
31 
32 Use the standard autoconf/automake sequence to compile and install the library.
33 \verbatim
34  ./autogen.sh # (optional, recommended)
35  ./configure
36  make
37  make install
38 \endverbatim
39 
40 \\subsubsection nommx Linker Configuration
41 
42 The default location for the installation is /usr/local/lib and /usr/local/include.
43 This libary path may need to be added to the file the linker configuration file:
44 \verbatim
45  vi /etc/ld.so.conf
46  ldconfig
47 \endverbatim
48 
49 \\subsubsection nommx Non-MMX Platforms
50 
51 To build without MMX code enabled (i.e. ARM, PPC, AMD64 architectures):
52 \verbatim
53  ./configure --disable-mmx
54  make
55  make install
56 \endverbatim
57 
58 \subsection visualstudio Windows (VS2012, VS2013)
59 
60 Open the SDL2_gfx.sln solution file, right click on the solution and choose 'Rebuild'.
61 
62 The SDL2 Visual Studio solution must be placed in a directory alongside SDL2_gfx and build in the same configuration, i.e. Debug or Release, beforehand so the referenced SDL2.lib file can be found.
63 
64 \subsection platformosx Mac OSX
65 
66 The usual autotools build chain should be used. MacPorts or fink may be required.
67 
68 Xcode is supported via templates. See Xcode.zip - this template only supports SDL2_gfx
69 and not the tests. For this template, the Deployment Target (the lowest version to run on)
70 is set to 10.11 and expects the SDL2.framework preinstalled in the default location: /Library/Frameworks.
71 
72 \section test_sec Test Programs
73 
74 Change to the ./test directory and run
75 \verbatim
76  ./autogen.sh
77  ./configure
78  make
79 \endverbatim
80 to create several test programs for the libraries functions. This requires
81 the SDL2_gfx library to be previously compiled and installed.
82 
83 See the source in the test/*.c files for some sample code and implementation hints.
84 
85 \section documentation_sec Documentation
86 
87 Please refer to the Doxygen-generated API documentation found in the
88 Docs/html folder as well as the test programs in the test folder.

Function Documentation

Uint32 _getTicks ( )

Internal wrapper to SDL_GetTicks that ensures a non-zero return value.

Returns
The tick count.

Definition at line 37 of file SDL2_framerate.c.

Uint32 SDL_framerateDelay ( FPSmanager *  manager)

Delay execution to maintain a constant framerate and calculate fps.

Generate a delay to accomodate currently set framerate. Call once in the graphics/rendering loop. If the computer cannot keep up with the rate (i.e. drawing too slow), the delay is zero and the delay interpolation is reset.

Parameters
managerPointer to the framerate manager.
Returns
The time that passed since the last call to the function in ms. May return 0.

Definition at line 146 of file SDL2_framerate.c.

int SDL_getFramecount ( FPSmanager *  manager)

Return the current framecount.

Get the current framecount from the framerate manager. A frame is counted each time SDL_framerateDelay is called.

Parameters
managerPointer to the framerate manager.
Returns
Current frame count or -1 for error.

Definition at line 126 of file SDL2_framerate.c.

int SDL_getFramerate ( FPSmanager *  manager)

Return the current target framerate in Hz.

Get the currently set framerate of the manager.

Parameters
managerPointer to the framerate manager.
Returns
Current framerate in Hz or -1 for error.

Definition at line 107 of file SDL2_framerate.c.

void SDL_initFramerate ( FPSmanager *  manager)

Initialize the framerate manager.

Initialize the framerate manager, set default framerate of 30Hz and reset delay interpolation.

Parameters
managerPointer to the framerate manager.

Definition at line 62 of file SDL2_framerate.c.

int SDL_setFramerate ( FPSmanager *  manager,
Uint32  rate 
)

Set the framerate in Hz.

Sets a new framerate for the manager and reset delay interpolation. Rate values must be between FPS_LOWER_LIMIT and FPS_UPPER_LIMIT inclusive to be accepted.

Parameters
managerPointer to the framerate manager.
rateThe new framerate in Hz (frames per second).
Returns
0 for sucess and -1 for error.

Sint16  x2,
Sint16  y2,
Uint8  r,
Uint8  g,
Uint8  b,
Uint8  a,
int  draw_endpoint 
)

Internal function to draw anti-aliased line with alpha blending and endpoint control.

This implementation of the Wu antialiasing code is based on Mike Abrash's DDJ article which was reprinted as Chapter 42 of his Graphics Programming Black Book, but has been optimized to work with SDL and utilizes 32-bit fixed-point arithmetic by A. Schiffler. The endpoint control allows the supression to draw the last pixel useful for rendering continous aa-lines with alpha<255.

Parameters
rendererThe renderer to draw on.
x1X coordinate of the first point of the aa-line.
y1Y coordinate of the first point of the aa-line.
x2X coordinate of the second point of the aa-line.
y2Y coordinate of the second point of the aa-line.
rThe red value of the aa-line to draw.
gThe green value of the aa-line to draw.
bThe blue value of the aa-line to draw.
aThe alpha value of the aa-line to draw.
draw_endpointFlag indicating if the endpoint should be drawn; draw if non-zero.
Returns
Returns 0 on success, -1 on failure.

double _evaluateBezier ( double *  data,
int  ndata,
double  t 
)

Internal function to calculate bezier interpolator of data array with ndata values at position 't'.

Parameters
dataArray of values.
ndataSize of array.
tPosition for which to calculate interpolated value. t should be between [0, ndata].
Returns
Interpolated value at position t, value[0] when t<0, value[n-1] when t>n.

Definition at line 3556 of file SDL2_gfxPrimitives.c.

int _gfxPrimitivesCompareInt ( const void *  a,
const void *  b 
)

Internal helper qsort callback functions used in filled polygon drawing.

Parameters
aThe surface to draw on.
bVertex array containing X coordinates of the points of the polygon.

The font data array is organized in follows: [fontdata] = [character 0][character 1]...[character 255] where [character n] = [byte 1 row 1][byte 2 row 1]...[byte {pitch} row 1][byte 1 row 2] ...[byte {pitch} row height] where [byte n] = [bit 0]...[bit 7] where [bit n] = [0 for transparent pixel|1 for colored pixel]

Parameters
fontdataPointer to array of font data. Set to NULL, to reset global font to the default 8x8 font.
cwWidth of character in bytes. Ignored if fontdata==NULL.
chHeight of character in bytes. Ignored if fontdata==NULL.

Macro Definition Documentation

#define GUARD_ROWS   (2)

Number of guard rows added to destination surfaces.

This is a simple but effective workaround for observed issues. These rows allocate extra memory and are then hidden from the surface. Rows are added to the end of destination surfaces when they are allocated. This catches any potential overflows which seem to happen with just the right src image dimensions and scale/rotation and can lead to a situation where the program can segfault.

#define MAX (   a,
  b 
)    (((a) > (b)) ? (a) : (b))

Returns maximum of two numbers a and b.

SDL_Surface* rotateSurface90Degrees ( SDL_Surface *  src,
int  numClockwiseTurns 
)

Rotates a 8/16/24/32 bit surface in increments of 90 degrees.

Specialized 90 degree rotator which rotates a 'src' surface in 90 degree increments clockwise returning a new surface. Faster than rotozoomer since no scanning or interpolation takes place. Input surface must be 8/16/24/32 bit. (code contributed by J. Schiller, improved by C. Allport and A. Schiffler)

Parameters
srcSource surface to rotate.
numClockwiseTurnsNumber of clockwise 90 degree turns to apply to the source.
Returns
The new, rotated surface; or NULL for surfaces with incorrect input format.

Definition at line 803 of file SDL2_rotozoom.c.

SDL_Surface* rotozoomSurface ( SDL_Surface *  src,
double  angle,
double  zoom,
int  smooth 
)

Rotates and zooms a surface and optional anti-aliasing.

Rotates and zoomes a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'angle' is the rotation in degrees and 'zoom' a scaling factor. If 'smooth' is set then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly.

Parameters
srcThe surface to rotozoom.
angleThe angle to rotate in degrees.
zoomThe scaling factor.
smoothAntialiasing flag; set to SMOOTHING_ON to enable.
Returns
The new rotozoomed surface.

Definition at line 1035 of file SDL2_rotozoom.c.

Returns the size of the resulting target surface for a rotozoomSurfaceXY() call.

Parameters
widthThe source surface width.
heightThe source surface height.
angleThe angle to rotate in degrees.
zoomxThe horizontal scaling factor.
zoomyThe vertical scaling factor.
dstwidthThe calculated width of the rotozoomed destination surface.
dstheightThe calculated height of the rotozoomed destination surface.

SDL_Surface* rotozoomSurfaceXY ( SDL_Surface *  src,
double  angle,
double  zoomx,
double  zoomy,
int  smooth 
)

Rotates and zooms a surface with different horizontal and vertival scaling factors and optional anti-aliasing.

Rotates and zooms a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'angle' is the rotation in degrees, 'zoomx and 'zoomy' scaling factors. If 'smooth' is set then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly.

Parameters
srcThe surface to rotozoom.
angleThe angle to rotate in degrees.
zoomxThe horizontal scaling factor.
zoomyThe vertical scaling factor.
smoothAntialiasing flag; set to SMOOTHING_ON to enable.
Returns
The new rotozoomed surface.

SDL_Surface* shrinkSurface ( SDL_Surface *  src,
int  factorx,
int  factory 
)

Shrink a surface by an integer ratio using averaging.

Shrinks a 32bit or 8bit 'src' surface to a newly created 'dst' surface. 'factorx' and 'factory' are the shrinking ratios (i.e. 2=1/2 the size, 3=1/3 the size, etc.) The destination surface is antialiased by averaging the source box RGBA or Y information. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly. The input surface is not modified. The output surface is newly allocated.

Parameters
srcThe surface to shrink.
factorxThe horizontal shrinking ratio.
factoryThe vertical shrinking ratio.
Returns
The new, shrunken surface.

void transformSurfaceY ( SDL_Surface *  src,
SDL_Surface *  dst,
int  cx,
int  cy,
int  isin,
int  icos,
int  flipx,
int  flipy 
)

Rotates and zooms 8 bit palette/Y 'src' surface to 'dst' surface without smoothing.

Rotates and zooms 8 bit RGBA/ABGR 'src' surface to 'dst' surface based on the control parameters by scanning the destination surface. Assumes src and dst surfaces are of 8 bit depth. Assumes dst surface was allocated with the correct dimensions.

Parameters
srcSource surface.
dstDestination surface.
cxHorizontal center coordinate.
cyVertical center coordinate.
isinInteger version of sine of angle.
icosInteger version of cosine of angle.
flipxFlag indicating horizontal mirroring should be applied.
flipyFlag indicating vertical mirroring should be applied.

SDL_Surface* zoomSurface ( SDL_Surface *  src,
double  zoomx,
double  zoomy,
int  smooth 
)

Zoom a surface by independent horizontal and vertical factors with optional smoothing.

Zooms a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'zoomx' and 'zoomy' are scaling factors for width and height. If 'smooth' is on then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly. If zoom factors are negative, the image is flipped on the axes.

Parameters
srcThe surface to zoom.
zoomxThe horizontal zoom factor.
zoomyThe vertical zoom factor.
smoothAntialiasing flag; set to SMOOTHING_ON to enable.
Returns
The new, zoomed surface.

Definition at line 1361 of file SDL2_rotozoom.c.

void zoomSurfaceSize ( int  width,
int  height,
double  zoomx,
double  zoomy,
int *  dstwidth,
int *  dstheight 
)

Calculates the size of the target surface for a zoomSurface() call.

The minimum size of the target surface is 1. The input factors can be positive or negative.

Parameters
widthThe width of the source surface to zoom.
heightThe height of the source surface to zoom.
zoomxThe horizontal zoom factor.
zoomyThe vertical zoom factor.
dstwidthPointer to an integer to store the calculated width of the zoomed target surface.
dstheightPointer to an integer to store the calculated height of the zoomed target surface.

Function Documentation

SDL2_ROTOZOOM_SCOPE SDL_Surface* rotateSurface90Degrees ( SDL_Surface *  src,
int  numClockwiseTurns 
)

Rotates a 8/16/24/32 bit surface in increments of 90 degrees.

Specialized 90 degree rotator which rotates a 'src' surface in 90 degree increments clockwise returning a new surface. Faster than rotozoomer since no scanning or interpolation takes place. Input surface must be 8/16/24/32 bit. (code contributed by J. Schiller, improved by C. Allport and A. Schiffler)

Parameters
srcSource surface to rotate.
numClockwiseTurnsNumber of clockwise 90 degree turns to apply to the source.
Returns
The new, rotated surface; or NULL for surfaces with incorrect input format.

SDL2_ROTOZOOM_SCOPE SDL_Surface* rotozoomSurface ( SDL_Surface *  src,
double  angle,
double  zoom,
int  smooth 
)

Rotates and zooms a surface and optional anti-aliasing.

Rotates and zoomes a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'angle' is the rotation in degrees and 'zoom' a scaling factor. If 'smooth' is set then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly.

Parameters
srcThe surface to rotozoom.
angleThe angle to rotate in degrees.
zoomThe scaling factor.
smoothAntialiasing flag; set to SMOOTHING_ON to enable.
Returns
The new rotozoomed surface.

SDL2_ROTOZOOM_SCOPE void rotozoomSurfaceSize ( int  width,
int  height,
double  angle,
double  zoom,
int *  dstwidth,
int *  dstheight 
)

Returns the size of the resulting target surface for a rotozoomSurface() call.

Parameters
widthThe source surface width.
heightThe source surface height.
angleThe angle to rotate in degrees.
zoomThe scaling factor.
dstwidthThe calculated width of the rotozoomed destination surface.
dstheightThe calculated height of the rotozoomed destination surface.

Definition at line 1013 of file SDL2_rotozoom.c.

SDL2_ROTOZOOM_SCOPE void rotozoomSurfaceSizeXY ( int  width,
int  height,
double  angle,
double  zoomx,
double  zoomy,
int *  dstwidth,
int *  dstheight 
)

Returns the size of the resulting target surface for a rotozoomSurfaceXY() call.

Parameters
widthThe source surface width.
heightThe source surface height.
angleThe angle to rotate in degrees.
zoomxThe horizontal scaling factor.
zoomyThe vertical scaling factor.
dstwidthThe calculated width of the rotozoomed destination surface.
dstheightThe calculated height of the rotozoomed destination surface.

SDL2_ROTOZOOM_SCOPE SDL_Surface* rotozoomSurfaceXY ( SDL_Surface *  src,
double  angle,
double  zoomx,
double  zoomy,
int  smooth 
)

Rotates and zooms a surface with different horizontal and vertival scaling factors and optional anti-aliasing.

Rotates and zooms a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'angle' is the rotation in degrees, 'zoomx and 'zoomy' scaling factors. If 'smooth' is set then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly.

Parameters
srcThe surface to rotozoom.
angleThe angle to rotate in degrees.
zoomxThe horizontal scaling factor.
zoomyThe vertical scaling factor.
smoothAntialiasing flag; set to SMOOTHING_ON to enable.
Returns
The new rotozoomed surface.

Definition at line 1056 of file SDL2_rotozoom.c.

SDL2_ROTOZOOM_SCOPE SDL_Surface* shrinkSurface ( SDL_Surface *  src,
int  factorx,
int  factory 
)

Shrink a surface by an integer ratio using averaging.

Shrinks a 32bit or 8bit 'src' surface to a newly created 'dst' surface. 'factorx' and 'factory' are the shrinking ratios (i.e. 2=1/2 the size, 3=1/3 the size, etc.) The destination surface is antialiased by averaging the source box RGBA or Y information. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly. The input surface is not modified. The output surface is newly allocated.

Parameters
srcThe surface to shrink.
factorxThe horizontal shrinking ratio.
factoryThe vertical shrinking ratio.
Returns
The new, shrunken surface.

Definition at line 1512 of file SDL2_rotozoom.c.

SDL2_ROTOZOOM_SCOPE SDL_Surface* zoomSurface ( SDL_Surface *  src,
double  zoomx,
double  zoomy,
int  smooth 
)

Zoom a surface by independent horizontal and vertical factors with optional smoothing.

Zooms a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'zoomx' and 'zoomy' are scaling factors for width and height. If 'smooth' is on then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly. If zoom factors are negative, the image is flipped on the axes.

Parameters
srcThe surface to zoom.
zoomxThe horizontal zoom factor.
zoomyThe vertical zoom factor.
smoothAntialiasing flag; set to SMOOTHING_ON to enable.
Returns
The new, zoomed surface.

SDL2_ROTOZOOM_SCOPE void zoomSurfaceSize ( int  width,
int  height,
double  zoomx,
double  zoomy,
int *  dstwidth,
int *  dstheight 
)

Calculates the size of the target surface for a zoomSurface() call.

The minimum size of the target surface is 1. The input factors can be positive or negative.

Parameters
widthThe width of the source surface to zoom.
heightThe height of the source surface to zoom.
zoomxThe horizontal zoom factor.
zoomyThe vertical zoom factor.
dstwidthPointer to an integer to store the calculated width of the zoomed target surface.
dstheightPointer to an integer to store the calculated height of the zoomed target surface.

Their only effect is that within double quotes, space and tab are treated like normal characters. - Backslashes not followed by double quotes are not special. - But 2*n+1 backslashes followed by a double quote become n backslashes followed by a double quote (n >= 0): \" -> " \\\" -> \" \\\\\" -> \\" */ #define SHELL_SPECIAL_CHARS "\"\\ \001\002\003\004\005\006\007\010\011\012\013\014\015\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037" #define SHELL_SPACE_CHARS " \001\002\003\004\005\006\007\010\011\012\013\014\015\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037" char ** prepare_spawn (char **argv) { size_t argc; char **new_argv; size_t i; /* Count number of arguments. */ for (argc = 0; argv[argc] != NULL; argc++) ; /* Allocate new argument vector. */ new_argv = XMALLOC (char *, argc + 1); /* Put quoted arguments into the new argument vector. */ for (i = 0; i < argc; i++) { const char *string = argv[i]; if (string[0] == '\0') new_argv[i] = xstrdup ("\"\""); else if (strpbrk (string, SHELL_SPECIAL_CHARS) != NULL) { int quote_around = (strpbrk (string, SHELL_SPACE_CHARS) != NULL); size_t length; unsigned int backslashes; const char *s; char *quoted_string; char *p; length = 0; backslashes = 0; if (quote_around) length++; for (s = string; *s != '\0'; s++) { char c = *s; if (c == '"') length += backslashes + 1; length++; if (c == '\\') backslashes++; else backslashes = 0; } if (quote_around) length += backslashes + 1; quoted_string = XMALLOC (char, length + 1); p = quoted_string; backslashes = 0; if (quote_around) *p++ = '"'; for (s = string; *s != '\0'; s++) { char c = *s; if (c == '"') { unsigned int j; for (j = backslashes + 1; j > 0; j--) *p++ = '\\'; } *p++ = c; if (c == '\\') backslashes++; else backslashes = 0; } if (quote_around) { unsigned int j; for (j = backslashes; j > 0; j--) *p++ = '\\'; *p++ = '"'; } *p = '\0'; new_argv[i] = quoted_string; } else new_argv[i] = (char *) string; } new_argv[argc] = NULL; return new_argv; } EOF ;; esac cat <<"EOF" void lt_dump_script (FILE* f) { EOF func_emit_wrapper yes | $SED -e 's/\([\\"]\)/\\\1/g' \ -e 's/^/ fputs ("/' -e 's/$/\\n", f);/' cat <<"EOF" } EOF } # end: func_emit_cwrapperexe_src # func_emit_exe_manifest # emit a Win32 UAC manifest for executable on stdout # Must ONLY be called from within func_mode_link because # it depends on a number of variable set therein. func_emit_exe_manifest () { cat < EOF } # func_win32_import_lib_p ARG # True if ARG is an import lib, as indicated by $file_magic_cmd func_win32_import_lib_p () { $opt_debug case `eval $file_magic_cmd \"\$1\" 2>/dev/null | $SED -e 10q` in *import*) : ;; *) false ;; esac } # func_mode_link arg... func_mode_link () { $opt_debug case $host in *-*-cygwin* | *-*-mingw* | *-*-pw32* | *-*-os2* | *-cegcc*) # It is impossible to link a dll without this setting, and # we shouldn't force the makefile maintainer to figure out # which system we are compiling for in order to pass an extra # flag for every libtool invocation. # allow_undefined=no # FIXME: Unfortunately, there are problems with the above when trying # to make a dll which has undefined symbols, in which case not # even a static library is built.

But we'll never go from static-only to shared-only. # ### BEGIN LIBTOOL TAG CONFIG: disable-shared build_libtool_libs=no build_old_libs=yes # ### END LIBTOOL TAG CONFIG: disable-shared # ### BEGIN LIBTOOL TAG CONFIG: disable-static build_old_libs=`case $build_libtool_libs in yes) echo no;; *) echo yes;; esac` # ### END LIBTOOL TAG CONFIG: disable-static # Local Variables: # mode:shell-script # sh-indentation:2 # End: # vi:sw=2 SDL2_gfx-1.0.4/Makefile.am100777 0 0 1532 12345353754 10253 0# Makefile.am for the SDL2_gfx library lib_LTLIBRARIES = libSDL2_gfx.la libSDL2_gfxincludedir = \ $(includedir)/SDL2 libSDL2_gfxinclude_HEADERS = \ SDL2_framerate.h \ SDL2_gfxPrimitives.h \ SDL2_imageFilter.h \ SDL2_rotozoom.h libSDL2_gfx_la_SOURCES = \ SDL2_framerate.c \ SDL2_gfxPrimitives.c \ SDL2_imageFilter.c \ SDL2_rotozoom.c EXTRA_DIST = \ autogen.sh libSDL2_gfx_la_LDFLAGS = \ -no-undefined \ -release $(LT_RELEASE) \ -version-info $(LT_CURRENT):$(LT_REVISION):$(LT_AGE) %.o : %.rc $(WINDRES) $< $@ # Rule to build tar-gzipped distribution package $(PACKAGE)-$(VERSION).tar.gz: distcheck pkgconfigdir = $(libdir)/pkgconfig pkgconfig_DATA = SDL2_gfx.pc # Additional cleanup rules DISTCLEANFILES = \ *~ \ SDL2_gfx.sdf \ SDL2_gfx.suo \ SDL2_gfx.vcxproj.user \ autom4te.cache/* \ Win32/Debug/* \ Win32/Release/* SDL2_gfx-1.0.4/Makefile.in100777 0 0 65530 12345353754 10314 0# Makefile.in generated by automake 1.11.6 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011 Free Software # Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ # Makefile.am for the SDL2_gfx library VPATH = @srcdir@ am__make_dryrun = \ { \ am__dry=no; \ case $$MAKEFLAGS in \ *\\[\ \ ]*) \ echo 'am--echo: ; @echo "AM" OK' | $(MAKE) -f - 2>/dev/null \ | grep '^AM OK$$' >/dev/null || am__dry=yes;; \ *) \ for am__flg in $$MAKEFLAGS; do \ case $$am__flg in \ *=*|--*) ;; \ *n*) am__dry=yes; break;; \ esac; \ done;; \ esac; \ test $$am__dry = yes; \ } pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ subdir = .

The current components of the SDL2_gfx library are: - Graphic Primitives (SDL2_gfxPrimitives.h, SDL2_gfxPrimitives.c) - Surface Rotozoomer (SDL2_rotozoom.h, SDL2_rotozoom.c) - Framerate control (SDL2_framerate.h, SDL2_framerate.c) - MMX image filters (SDL2_imageFilter.h, SDL2_imageFilter.c) - Build-in 8x8 Font (SDL2_gfxPrimitives_font.h) Note that SDL2_gfx is compatible with SDL version 2.0 (not SDL 1.2). \section install_sec Installation \subsection unix Unix/Linux Use the standard autoconf/automake sequence to compile and install the library. \verbatim ./autogen.sh # (optional, recommended) ./configure make make install \endverbatim \\subsubsection nommx Linker Configuration The default location for the installation is /usr/local/lib and /usr/local/include. This libary path may need to be added to the file the linker configuration file: \verbatim vi /etc/ld.so.conf ldconfig \endverbatim \\subsubsection nommx Non-MMX Platforms To build without MMX code enabled (i.e. ARM, PPC, AMD64 architectures): \verbatim ./configure --disable-mmx make make install \endverbatim \subsection visualstudio Windows (VS2015) Open the SDL2_gfx.sln solution file, right click on the solution and choose 'Rebuild'. The SDL2-2.0.5 folder must be placed in a directory alongside SDL2_gfx (or sdl2gfx-code) and build in the same configuration, i.e. Debug or Release, beforehand so the referenced SDL2.lib file can be found. \subsection platformosx Mac OSX The usual autotools build chain should be used. MacPorts or fink may be required. Xcode is supported via templates. See Xcode.zip - this template only supports SDL2_gfx and not the tests. For this template, the Deployment Target (the lowest version to run on) is set to 10.11 and expects the SDL2.framework preinstalled in the default location: /Library/Frameworks. \section test_sec Test Programs Change to the ./test directory and run \verbatim ./autogen.sh ./configure make \endverbatim to create several test programs for the libraries functions. This requires the SDL2_gfx library to be previously compiled and installed.
