SDL_SetSurfaceRLE

Set the RLE acceleration hint for a surface.

Syntax

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.

Remarks

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