NAME
SDL_FillSurfaceRects - Perform a fast fill of a set of rectangles with a specific color.
HEADER FILE
Defined in SDL3/SDL_surface.h
SYNOPSIS
#include "SDL3/SDL.h" bool SDL_FillSurfaceRects(SDL_Surface *dst, const SDL_Rect *rects, int count, Uint32 color);
DESCRIPTION
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 .
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 true on success or false on failure; call SDL_GetError () for more information.
AVAILABILITY
This function is available since SDL 3.2.0.
