You might use a macro, either this: #define getpixel(s,x,y) \ (getpixel_fns[(s)->format->BytesPerPixel]((s),(x),(y))) Or this: #define DECL_PUTPIXEL(s) \ void (*putpixel)(SDL_Surface *, int, int, Uint32) = \ putpixels[(s)->format->BytesPerPixel]) Maybe it would be less painful to just have a plain function pointer, ensuring that all surfaces are in the screen format. Add an assert() for BytesPerPixel being wrong, and you'll see that very little is in any other format. Alternately, leave the screen using a function pointer and have everything else just use the 32-bit version. _______________________________________________ Tuxpaint-dev mailing list [email protected] http://tux4kids.net/mailman/listinfo/tuxpaint-dev
