erase-by

Arguments: stream offset

Erases (i.e. replaces with the background color or texture) from stream the line from the current position (see current-position) to the position

(position+ (current-position stream) offset)

offset must be a position object (see make-position). stream should be a graphical-stream.

Contrast with draw-by which draws the line on stream.

position+ adds two positions.

To use individual coordinates rather than creating position objects, see erase-by-x-y.
