SDL_FillRect

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

Syntax

int SDL_FillRect
    (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_SetClipRect()), then this function will fill based on the intersection of the clip rectangle and rect.

Code Examples

/* Declaring the surface. */
SDL_Surface *s;

/* Creating the surface. */
s = SDL_CreateRGBSurface(0, width, height, 32, 0, 0, 0, 0);

/* Filling the surface with red color. */
SDL_FillRect(s, NULL, SDL_MapRGB(s->format, 255, 0, 0));
