Draw and redraw orthogonal projections

[thehobbit]

Hello everyone,
I have a problem using Orthogonal_Views in my JAVA plugin.
When I draw something on a slice on the main image(for example: imp.setOverlay(overlay)), I need the orthogonal projections(xz_image, yz_image) to be redrawn according to the changes I made.
There is a way to do it? Because it seems that the orthogonal projections works only with ImageProcessors,
I hope I'm wrong.

Another thing I need is the exact opposite.
If I draw something on one of the orthogonal projections(on xz_image or on yz_image), the changes have to be drawn accordingly on the others. The problem I noticed about this, is that the projections are not stacks, so I have problem also drawing polygon, or using brush tool, and also with other things like mouseListener ecc.
There's a solution also for this or another way to work with those images?

Thanks in advance.
