SDL_FillSurfaceRect

Perform a fast fill of a rectangle with a specific color.

Header File

Syntax

int SDL_FillSurfaceRect(SDL_Surface *dst, const SDL_Rect *rect, Uint32 color);

Function Parameters

dst	the SDL_Surface structure that is the drawing target
rect	the SDL_Rect structure representing the rectangle to fill, or NULL to fill the entire surface
color	the color to fill with

Return Value

Returns 0 on success or a negative error code on failure; call 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() or 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()), then this function will fill based on the intersection of the clip rectangle and rect.

Version

This function is available since SDL 3.0.0.
