[Paraview] WriteImage Arguments

[Andy Bauer]

The third argument is a magnification factor.  I guess there wasn't a
default value of 1 set for the magnification factor so you need to put that
in automatically.

You should be able to just use WriteImage(<output file name>) without using
the view object. It determines the image output type from the file
extension.
