This looks really bad. Please try to reduce this to the smallest amount of
code possible, and open a bugzilla with "regression" in the title.
Hopefully, you can create an SWT-only test case by creating your own Printer
device and drawing the Image straight to the printer.

Has anything come of this problem? I never saw where a new bugzilla
was created.
We have moved to GEF 3.0 and want to use the built-in printing support
to print our diagrams. It all works great except that any GIF's on the
diagram print as a small black dot as shown in the PDF's posted in an
earlier message by someone else in this thread. Are there any
workarounds? Could we use another image format like PNG?
By "built-in" printing I mean that we are just using your PrintAction
class with no subclassing, and other than this problem it all works
great, much better than 2.1.
