[vtkusers] Question on Image Background transparency

[rakesh patil]

Hello,


Well, isnt there any method to make the background of an image
transparent.?? Whatever exists as white color on the renderer, should be
trasparent. Because, the output of my application should be an image which
can be ported onto the Google Earth. Now on google earth it wont look good
with white background stuff. So i need to make that background transparent.
How is it possible..??

Thanks


Regards
Rakesh Patil
