For the VM700T+ are there any commands or hints for obtaining a screen image capture via GPIB?

The VM700A/T documentation does not provide commands or recommended mechanisms for obtaining a screen capture of a displayed waveform or measurement screen.  Some hints on possible ways to do a GPIB capture have been gleaned from conversations with various programmers.  These hints and code samples are provided in an attached document, and are offered on an "as is" basis.  No in-depth additional programming assistance is expressed or implied beyond "best effort only".
