copy-graphics-context

Arguments: stream &optional (result-context (make-graphics-context stream))

Returns a graphics-context object that stores the current drawing style options of stream. stream should be a cg-stream.

The graphics-context can later be given to the same or another stream to resume using the saved drawing style options. The specific values saved are foreground-color, background-color, font, line-width, line-dashing, line-end, line-join, line-texture, fill-texture, background-texture, current-position, and stream-origin.

If a graphics-context is passed as the result-context argument, then this object is filled in and returned. Otherwise a new graphics-context is created and returned. (You create a graphics context object with make-graphics-context. Pass the same stream to that function as was passed as the first argument to this function.)
