Set the RLE acceleration hint for a surface.


int SDL_SetSurfaceRLE(SDL_Surface * surface,
                      int flag);

Function Parameters

surface the SDL_Surface structure to optimize
flag 0 to disable, non-zero to enable RLE acceleration

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.


If RLE is enabled, color key and alpha blending blits are much faster, but the surface must be locked before directly accessing the pixels.


This function is available since SDL 2.0.0.
