Hi,
I am currently modifying the logic example to create a program to suit
my needs. However, i have no need for the outline and overview and has
removed it. Strangely, i found my program creating images of the snap shot
of the canvas. I suspect that this is done for displaying the contents of
the canvas for the overview which i no longer have? When are these snap
shots executed? How does the overview of the Logic Example works, i simply
cannot trace where this originates. Thanks in advance!
Regards,
Evon

draw2d is double buffered, so Images are used for painting in general.

Does that mean that those images must be created regardless of whether i'm
using the outline or not? I just discovered that these images is quite
heavy and they don't seem to get disposed. Is there no way i can clear
these images? are they absolutely necessary?

Which version of GEF are you using? Look at BufferedGraphicsSource.flush()
to see the behavior for your version.
