[Paraview] Making vtkImageMathematics available in ParaView filters

[Jérôme]

Hi,

Many thanks for your quick answer. The problem I described was observed on
Paraview 3.4 release, debug build. I have a 3.5 CVS (not updated, so bad...)
on which I tried my XML just right now: "Image Math" is no more gray!! I am
able to apply the filter on a single image, with "Add constant", "Multiply
by constant", etc.

The new problem is when I want to add two image. I selected two mandelbrot
sources, then I plugged the "Image Math" filter. The output window claims:
"Input port 0 of algorithm vtkImageMathematics(0x7f081c4bcb70) has 2
connections but is not repeatable".

I tried the repeat_command="1" statement, without optimism and not much
success... It seems that vtkImageMathematics input is old-fashionned, but
the VTK doc says that SetInput1 and SetInput2 is like involking
AddInputConnection. Where do I miss something ???

Thanks for all,

Jerome
