sdlxGetSurfaceColorMod function surface

SdlxColor? sdlxGetSurfaceColorMod(Pointer<SdlSurface> surface)

Get the additional color value multiplied into blit operations.

\param surface the SDL_Surface structure to query. \param r a pointer filled in with the current red color value. \param g a pointer filled in with the current green color value. \param b a pointer filled in with the current blue color value. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function can be called on different threads with different surfaces.

\since This function is available since SDL 3.2.0.
