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 poly-
       gon defined by the points array.  For an explanation of
       fill_rule, see XCreateGC.

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