Grabbing screen shots (but not to file)

[farshizzo]

There is no command that will return the raw data of the screen capture. Capturing to a file and reading the file is probably the easiest solution. Do you need this for real-time use?

When you issue the viz.screencapture command the file is not created immediately. It is created at the end of the next frame. So when you issue the command wait until the next frame before reading the file.
