A little question of a sdl beginner

SDL Development

Can i invert the SDL_BlitSurface by setting the src rect to
src.w = -32;
src.h = -32;
src.x = x+w;
src.y = y+h;

This is very important for me to take down animation frame number.!
Thanxs in advance…to all who answer.
And big thanx especially to Sam Lantinga for his great API.!

no, the src/dest rects only control position and clipping
(width and height are unsigned by the way)

thanxs… and i forgot that they are Uint32’s …
Is there any other fast way for inverting Bitmaps…
