[Paraview] Image Mathematics

[Jérôme]

Hi again,
I found the origin of the pipeline issue: The XML description of the filter
must set the name of one input to "Input". The 2-inputs ImageMathematics
works well with first input name="Input" rather than name="Input1".
Second input name="Input2" does not have to be changed.

Should I fill a bug entry for that? Is it a design constraint?

Best regards,
Jerome
