Hi Stefan,
The JUMP rendering architecture was never designed for something like
animation. The only way I have found to make it work is to turn off the
RenderManager and do the rendering yourself. You should be able to find
some hints on how to do that in LayerPrinter2, if I remember correctly.
Perhaps AbstractZoom too.
I could also make some changes to RenderManager to support notification that
rendering is complete as I did in SkyJUMP, but it doesn't completely make
the problem go away.
regards,
Larry
