[vtkusers] Saving images

[Christian Chilan]

Hi there,

I'm trying to save rendered images in a file (bmp,
jpg, ...). I've used the documented methods but they
only appear to do a screen capture. Thus, the user
must clear the rendering window of any object (dialog
boxes, widgets) that might be in front of it before
saving the image. Otherwise, the overlapping object
appears in the saved file.

I'd appreciate any idea in how to perform the saving
without the clearance procedure.

Christian
