OK, so I'll reply to the list (I already replied to Andrew in private). I don't know much about this. Prabhu Ramachandran might know more. I can however point you to where this is used in Mayavi2: The file where the tvtk code is, is: https://svn.enthought.com/enthought/browser/branches/enthought.mayavi_2.0/tests/ common.py the function you are interested in is "compare_image". It is used in tests in the directory: https://svn.enthought.com/enthought/browser/branches/enthought.mayavi_2.0/tests I hope you'll find what you are interested in with this info and the tvtk code related. From the tvtk code you can go up to the vtk code (the functions have the same name). If you don't find what you are interested in, you will have to ask Prabhu or someone who knows vtk better than I do.
