SDL_FillRects

Perform a fast fill of a set of rectangles with a specific color.

Header File

Defined in SDL_surface.h, but apps should only #include "SDL.h"!

Syntax

int SDL_FillRects
    (SDL_Surface * dst, const SDL_Rect * rects, int count, Uint32 color);

Function Parameters

dst	the SDL_Surface structure that is the drawing target
rects	an array of SDL_Rects representing the rectangles to fill.
count	the number of rectangles in the array
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_SetClipRect()), then this function will fill based on the intersection of the clip rectangle and rect.

Version

This function is available since SDL 2.0.0.
