Hello, I am resurrecting this thread as I need to impose a certain resolution on a renderer. Even though the window can be 800x600, I want it at 500px x 500px. Does the VTK rendering / openGLrenderwindow have the option such as SetResolution(x,y) ? I couln't find anything. Thanks! -- Sent from: http://vtk.1045678.n5.nabble.com/VTK-Users-f1224199.html
