I would like to create a picture off-screen, but it seems that the view
should be visible and always bigger than my picture otherwise the view is
not completly drawn.
How can I adress this?
I've contributed code in the contrib library (available by anonymous ftp
from cambridge.apple.com in the file
If you examine the oou-utils.lisp file within the binhexed archive,
you'll find routines that manipulate a class of windows called a wmgr-view.
The routines allow you to "save" and "restore" a portion of the screen view
(either in color or 1-bit monochrome). Part of the code appears below. Notice
that it always sets the clip region of a wmgr-view to the maximum extent.
Hopefully, this will help.
(defmethod view-clip-region ((sv WMgr-view))
(declare (ignore sv))
