fillRects method

bool fillRects(
  1. List<Rectangle<double>> rects,
  2. int color
)

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

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.

\param dst the SDL_Surface structure that is the drawing target. \param rects an array of SDL_Rects representing the rectangles to fill. \param count the number of rectangles in the array. \param color the color to fill with. \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.

Implementation

bool fillRects(List<math.Rectangle<double>> rects, int color) {
  var rectsPointer = rects.callocInt();
  var result = sdlFillSurfaceRects(this, rectsPointer, rects.length, color);
  calloc.free(rectsPointer);
  return result;
