###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_FillSurfaceRect Perform a fast fill of a rectangle with a specific color. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_surface.h) ## Syntax ```c bool SDL_FillSurfaceRect(SDL_Surface *dst, const SDL_Rect *rect, Uint32 color); ``` ## Function Parameters | | | | | ---------------------------- | --------- | ---------------------------------------------------------------------------------------------------------- | | [SDL_Surface](SDL_Surface) * | **dst** | the [SDL_Surface](SDL_Surface) structure that is the drawing target. | | const [SDL_Rect](SDL_Rect) * | **rect** | the [SDL_Rect](SDL_Rect) structure representing the rectangle to fill, or NULL to fill the entire surface. | | [Uint32](Uint32) | **color** | the color to fill with. | ## Return Value (bool) Returns true on success or false on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Remarks `color` should be a pixel of the format used by the surface, and can be generated by [SDL_MapRGB](SDL_MapRGB)() or [SDL_MapRGBA](SDL_MapRGBA)(). If the color value contains an alpha component then the destination is simply filled with that alpha information, no blending takes place. If there is a clip rectangle set on the destination (set via [SDL_SetSurfaceClipRect](SDL_SetSurfaceClipRect)()), then this function will fill based on the intersection of the clip rectangle and `rect`. ## Version This function is available since SDL 3.1.3. ## See Also - [SDL_FillSurfaceRects](SDL_FillSurfaceRects) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategorySurface](CategorySurface)
