erase-contents-polygon

Arguments: stream vertices

Erases (i.e. replaces with the background color or texture) the specified filled polygon from stream. A polygon is specified by vertices, which should be a sequence (list or vector) of positions (see make-position). A line is drawn connecting the first vertex with the final vertex.

stream should be a cg-stream.

Contrast with fill-polygon which draws the filled polygon on stream.
