XPolygonRegion, XClipBox - generate regions


Region XPolygonRegion(XPoint points[], int n, int fill_rule); int XClipBox(Region r, XRectangle *rect_return);


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.


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.
