Re: [Visualpython-users] Why no screenshot function?

[Bruce S. <Bru...@NC...>]

But that's the fundamental problem. If I understand your note correctly, you 
want "decent image resolution". The only way I know to get that is to use 
ray-tracing, through POV-ray, which is time-consuming, but no bitmap image can 
give comparable results. Moreover, the real-time shading in Visual is no match 
for ray-tracing, no matter what the resolution in dots per inch.

However, as was pointed out you might be able to get by with using a very large 
Visual window on a very large monitor, if the dots per inch is adequate for your 
purposes and you can tolerate the shading and lighting done by Visual.
