The only other idea I have is to load the information directly from the
programmable source.
I once wrote a programmable source that queried an external process to populate
data arrays.

I thought one needs to convert a vtkarray to a numpy array with
x = numpy.array(inputs[0].PointData['Scalars_'])
before doing anything with it.

The legacy VTK formats are agnostic with respect to endinaness, which is
one reason why I almost never use the binary versions of them.
If you can't link to VTK and use vtkXMLImageDataWriter, as David

to convert from lega

Use a glyph filter, then set the glyph type to 2D glyph, and then set
the glyph type to filled circle.

Unfortunately, this tends to fail because
paraview.vtk.vtkXMLImageDataWriter does not exist.
The only way I can get this to work is to install both VTK and ParaView
and mix calls to the paraview.vtk the vtk modules. This seems
redundant. Is there a better way?
Thanks,

Ignore this part of my email. I hadn't realized that 3.12 already has

It was
