[vtkusers] Generate in-memory JPEG images in Python

[Shead, Timothy]

Gang:

I'm experimenting with generating an offscreen JPEG image on a web-server using VTK and Python, but I'm hung-up on how to convert the vtkUnsignedCharArray returned by vtkJPEGWriter::GetResult() into a Python string or buffer.  Any thoughts?  I see that it's easy to create a numpy array that points to the same memory, maybe there's something I could do with it?

Many thanks,
Tim
