Hi Matthieu, by accident I stumbled over the same problem some days ago. I wanted to use MITK rendering only in a small part (viewport) of a render window. If you modify the viewport of the vtkRenderer by SetViewport(..), this seems to work fine with all VTK mappers. For the few OpenGL mappers in MITK I had to implement a fix: http://bugs.mitk.org/show_bug.cgi?id=13543 This basically scales the OpenGL mapper outputs into the defined viewport. Comments on this fix are very welcome. I didn't check how vtkMitkRectangleProp is integrated into rendering but I find the same OpenGL code pieces which were wrong in the bug I fixed (the lines around glOrtho()). You could try if a fix similar to mine will help you (and then file a bug and patch if you want).
