SDL_FillSurfaceRect - Man Page
Perform a fast fill of a rectangle with a specific color.
Synopsis
#include <SDL3/SDL_surface.h> bool SDL_FillSurfaceRect(SDL_Surface *dst, const SDL_Rect *rect, 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.
- 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 true on success or false on failure; call SDL_GetError() for more information.
Thread Safety
This function can be called on different threads with different surfaces.
Availability
This function is available since SDL 3.2.0.
