[Paraview] PNG compression when making screenshot

[Joe Borġ]

I'm trying to reduce the size of the screenshots made in batch.  Using
trace, I found

view = GetRenderView()
view.CompressorConfig = 'vtkZlibImageCompressor 0 9 4 0'
WriteImage('test.png')

...but they're the same size with and without the compression.  The
dimension is 1700x900 and I'm getting 1.4MB per image.  When I make a
similar image in Ensight, I can use the max compression setting to get the
image down to 400KB.

I'm not sure if it's the command or the compression lib that are wrong.
