With this fix, the edges do still do not intersect 100% due to the difference in the algorithms. But now a polygon will never draw outside of the area enclosed by a polyline.) Ver 2.0.7 - Sun Jun 8 08:17:38 EDT 2003 * Added MacOS X Project Builder code * changed SDL include to <SDL/SDL.h> * Added bezier curve Ver 2.0.6 - Sat May 25 15:12:17 EDT 2002 * Fixed clipping code for most primitives * Added clipping code for character * Added VC7 project file Ver 2.0.5 - n/a * Removed some unused code Ver 2.0.4 - Sat Feb 9 22:09:45 EST 2002 * Fixed rectangle drawing bug on edges for A<255 * Added trigons (triangles) as wrapper calls to polygon. Ver 2.0.3 - Sat Jan 26 10:06:16 EST 2002 * Zipped VisualC directory to avoid EOL problems. * Fixed aalineColor call (y2 parameter was y1). * Fixed rotozoom bug that caused black or undefined pixels on edges. Ver 2.0.2 - Sat Jan 19 21:41:28 EST 2002 * Removed dependency from GL libraries during compile. * Added VisualC makefile. Ver 2.0.1 - Sat Jan 5 22:08:17 EST 2002 * New better quality aacircle/aaellipse code * Better locking optimization for a 4-8% speed improvement on some primitives (line, aaline, circle, ellipse) Ver 2.0 - Sat Dec 29 16:27:57 EST 2001 * Initial release of SDL_gfx based on SDL_gfxPrimitives and SDL_rotozoom code. * Added framerate code and testprogram. * Added imageFilters code and testprogram. * New distribution: source code, README, configure system etc. Previous versions ================= SDL_gfxPrimitives: ------------------ Ver 1.5 - Mon Jul 2 11:27:40 EDT 2001 * New alpha blending code for factor 4 speedups if a<255 on all functions. * Modified include file for W32 DLL support. * Added VC6 project files for DLL and static library building. * Added simple AA-circle/-ellipse routine - quality needs improvement. * Removed 32bit shift on 64bit number from aaline for better portability across platforms. * Removed a couple more compiler warnings (i.e. purely cosmetic fix). Ver 1.4 - Sun Jun 3 11:52:07 EDT 2001 * Fixed hline, vline and rectangle clipping and result codes. * Fixed AA-line arithmetic (was alpha subtraction, should be alpha ratio). * More caching on fonts for speedups. * More pointer checks in several places. * New special cases for ellipses for rx=0/ry=0. * Same sanity checks for circles/ellipses. * Same return code for polygon/filledpolygon. Ver 1.3 - Thu May 31 12:41:35 EDT 2001 * Minor cleanups and fixes (gcc -Wall is your friend). Ver 1.2 again - Thu Apr 5 07:50:57 EDT 2001 * Fixed lineRGBA and aalineRGBA calls (had coordinate-passing mixed up twice, thanks Lion for pointing this out) Ver 1.2 - Wed Apr 4 08:32:42 EDT 2001 * Changed to a dual, you-have-the-choice(TM) licencing system to accomodate GPL developments using SDL_gfxPrimitives. * Some minor fixes (thanks Karl). * All routines return proper result code now. * Clipping for aaline, circle and ellipse. Ver 1.1 - Thu Mar 22 15:28:27 EST 2001 * Added code for Alpha=255 pixel drawing through direct memory writes to all routines resulting in a much faster performance (factor 5 to 20) for non transparent pixels. * New test and benchmark program with better info and nicer look. * More info in README. Proper licence file. Comment cleanup. Ver 1.0 - Fri Mar 16 08:38:07 EST 2001 * Initial release SDL_rotozoom: ------------- Ver 1.6 - Mon Nov 19 21:19:26 EST 2001 * Added interpolation to alpha channel (simplifies code) * Ran the sourcecode through 'indent' for better readability Ver 1.5 - Sat Jul 7 13:02:07 EDT 2001 * Added project files (VisualC.zip) and modifications for VC project building. * Fixed old versioning in configure.in file. * Fixed LICENSE file and LGPL source reference. Ver 1.4 - Mon Jun 4 12:15:31 EDT 2001 * Removed SDL_SoftStretch call again in favour of an internal zoom routine. * Added new zoomSurface() function with seperate X and Y zoom factors. Ver 1.3 - Thu May 31 08:37:36 EDT 2001 * Modified code to handle RGBA or ABGR source surfaces transparently. * More error checking, source surface locking. * Slighly expanded test program with event handling. Ver 1.2 - Wed May 30 18:18:05 EDT 2001 * Fixed the completely broken 32bit routine's pointer arithmetic. * Uses SDL_SoftStretch in certain cases (angle=0, smooth=0). * Convert source surface on the fly if not 8/32bit. * Added license file - was empty before (duh). Ver 1.1 - Wed May 23 15:04:42 EDT 2001 * Added automake/autoconf scripts and testprogram. Ver 1.0 - Fri Mar 16 08:16:06 EST 2001 * Initial release
