sdlSetSurfaceRle function surface

bool sdlSetSurfaceRle(
  1. Pointer<SdlSurface> surface,
  2. bool enabled
)

Set the RLE acceleration hint for a surface.

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

\param surface the SDL_Surface structure to optimize. \param enabled true to enable RLE acceleration, false to disable it. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function is not thread safe.

\since This function is available since SDL 3.2.0.
