XFillRectangles()														 XFillRectangles()

Name
  XFillRectangles - fill multiple rectangular areas.

Synopsis
  XFillRectangles(display, drawable, gc, rectangles, nrectangles)
	Display *display;
	Drawable drawable;
	GC gc;
	XRectangle *rectangles;
	int nrectangles;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  drawable  Specifies the drawable.

  gc	    Specifies the graphics context.

  rectangles
	    Specifies a pointer to an array of rectangles.

  nrectangles
	    Specifies the number of rectangles in the array.

Description
  XFillRectangles() fills multiple rectangular areas in the specified drawable using the graphics context.

  The  x  and  y coordinates of each rectangle are relative to the drawable's origin, and define the upper left corner of the rectangle.  The
  rectangles are drawn in the order listed.  For any given rectangle, no pixel is drawn more than once.  If rectangles intersect, the  inter-
  secting pixels will be drawn multiple times.

  In R4 and earlier there is a limit to the number of rectangles that can be drawn in a single call, based on the maximum request size, which
  varies according to the server.  In R5, Xlib chops your call into as many protocol requests as required.  To determine how many  rectangles
  you  can  draw  in  a single call in R4, find out your server's maximum request size using XMaxRequestSize().  Subtract three and divide by
  two, and this is the maximum number of rectangles you can fill in a single XDrawRectangles() call.

  XFillRectangles() uses these graphics  context  components:	function,  plane_mask,	fill_style,  subwindow_mode,  clip_x_origin,  clip_y_
  origin,  and	clip_ mask.  This function also uses these graphics context components depending on the fill_ style:  foreground, background,
  tile, stipple, ts_x_origin, and ts_y_ origin.

  For more information, see Volume One, Chapter 6, Drawing Graphics and Text, and Chapter 5, The Graphics Context.
