Allegro CL version 8.2
Unrevised from 8.1 to 8.2.
8.1 version

erase-polyline

Arguments: stream vertices

Erases (i.e. replaces with the background color or texture) the specified polyline from stream. A polyline is specified by vertices, which should be a sequence (list or vector) of positions (see make-position). Lines connect each vertex with the next vertex but (in contrast to a polygon) no line connects the last vertex to the first vertex.

stream should be a cg-stream.

Contrast with draw-polyline which draws the polyline on stream.
