Summary0013137: Cannot save images created using python calculator
DescriptionCannot save image data that was created using the python calculator. Often I use paraview to do simple arithmetic on image data, which I then would like to save for further processing. Not being able to do so with the python calculator is quite limiting.

Minimal example, with Paraview 3.14.0 on Ubuntu.
- Load image
- Python calculator:
Expression: inputs[0].PointData['MetaImage'] // i.e. just copy data over
Array Association: point data
Copy arrays: off
- Resulting image looks good
- Select python calculator result, File->Save Data, save as .mhd
- Reload image - data extents are correct, but all values are 0

Somewhat similarly -
If you use the Calculator instead of the Python Calculator, there is no way to turn off "copy arrays", so the output image typically has two data arrays - the original input array, and the result of the calculation. If you save this as .mhd, the result has only one data array - the result of the calculation. I would expect a .mhd with two channels.
