The rotozoom code is not ASM-speed quality, but it should be fast enough even for some realtime effects if the CPU is good or bitmaps small. Note: All _Color routines expect the color to be in the format 0xRRGGBBAA. Surface locking is implemented in each routine and the library should work well with hardware accelerated surfaces.Ĭurrently, The following Anti-Aliased drawing primitives are available: Surface depths supported are 1,2,3 and 4 bytes per pixel. Build-in 8x8 Font ( SDL_gfxPrimitives_font.h)Ĭare has been taken so that all routines are fully alpha-aware and can blend any primitive onto the target surface if ALPHACustom Blit functions ( SDL_gfxBlitFunc.h, SDL_gfxBlitFunc.c).MMX image filters ( SDL_imageFilter.h, SDL_imageFilter.c).

Framerate control ( SDL_framerate.h, SDL_framerate.c).Rotozoomer ( SDL_rotozoom.h, SDL_rotozoom.c).Graphic Primitives ( SDL_gfxPrimitives.h, SDL_gfxPrimitives.c).The current components of the SDL_gfx library are: Note that SDL_gfx is compatible with SDL version 1.2 (not SDL2).

The SDL_gfx library evolved out of the SDL_gfxPrimitives code which provided basic drawing routines such as lines, circles or polygons for SDL Surfaces and adding a couple other useful functions for zooming images for example and doing basic image processing on byte arrays.

I tried to exclude LIBCMT as advised here, but then I get a bunch of unresolved externals.Email aschiffler at ferzkopp dot net to contact the author or better check author's homepage at for the most up-to-date contact information. I added dependencies to winmm.lib, imm32.lib, version.lib as explained here. If I build with SDL2 static lib, but with Runtime Library 'Multi-threaded debug' instead of 'Multi-threaded', my application works. I can build SDL2 as dynamic dll or static dll, and in both cases my application is working. The application builds, but at execution it crashes with 'application.exe has triggered a breakpoint.'Īccording to Visual debugger, this happens line 98 in SDL_stdlib.c: (the line after _chktsk() below) I built SDL2 from latest repository, using the Visual 2012 project provided, with modifications so that it builds as a static lib with static VC runtime. I encounter an error when statically linking SDL2 in my application with Visual 2012.
