SDL_FillRect
Use this function to perform a fast fill of a rectangle with a specific color.
Contents
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; see Remarks for details |
Return Value
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
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));
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.
