clear-page

Arguments: &optional stream

Resets the contents of the argument stream to the background texture that initially filled the stream. The function is useful for clearing windows. Changes to the background-color or background-texture often do not take effect until clear-page is called. stream should be a cg-stream.

If stream is a text-edit-pane, clear-page removes all text in the pane.
