[GEF 3.2.0 and also GEF CVS head]
I have an ImageFigure subclass which returns true from
useLocalCoordinates(). I also set a border on this ImageFigure.
When the ImageFigure repaints, the image top-left corner is rendered at
(0, 0), and so the image is overlapped by the top & left borders, and
whitespace shows between the image and the bottom & right borders.
I suspect this is a bug; I think the implementation of
ImageFigure.paintFigure() should not call:
graphics.drawImage(getImage(), x, y);
but instead:
graphics.drawImage(getImage(), x + getInsets().left, y + getInsets().top);
Does that sound correct, or am I doing something silly?
Thanks,
Jason.

ImageFigure should work with a border. You've found a bug in that
getClientArea should not be called from paintFigure(). Please open a bug
report.
The fix is something like:
Rect area = getBounds().getCropped(getInsets());
