make-graphics-context

Arguments: stream

Creates and returns a graphics-context object that is valid for use with stream. stream should be a cg-stream.

A graphics-context object is useful only for passing to copy-graphics-context multiple times as the value of the optional result-context argument, in order to avoid consing a graphics-context object on each call. The stream should be the same value as passed to copy-graphics-context.
