[vtkusers] Saving result of volume rendering in a .pgm 2D image

[R R]

Hello all,

I have a question about how we can save the result of volume rendering in .pgm format. I mean I have a volume from which a 2D image is created using raycasting and is shown on the screen. I want to save this 2D image in a .pgm file. Could any body please give me some hint how I can do that.

Thanks so much.

Regards,
Rane
