XPolygonRegion(3X11)

     NAME
          XPolygonRegion, XClipBox - generate regions

     SYNTAX
          Region XPolygonRegion(points, n, fill_rule)
                XPoint points[];
                int n;
                int fill_rule;

          XClipBox(r, rect_return)
                Region r;
                XRectangle *rect_return;

     ARGUMENTS
          fill_rule Specifies the fill-rule you want to set for the
                    specified GC.  You can pass EvenOddRule or
                    WindingRule.

          n         Specifies the number of points in the polygon.

          points    Specifies an array of points.

          r         Specifies the region.

          rect_return
                    Returns the smallest enclosing rectangle.

     DESCRIPTION
          The XPolygonRegion function returns a region for the polygon
          defined by the points array.  For an explanation of
          fill_rule, see XCreateGC.

          The XClipBox function returns the smallest rectangle
          enclosing the specified region.
