[Paraview] Saving image in VTK format

[Moreland, Kenneth]

VTK has a data type called structured grid that is different than image data (and also different than unstructured grid).  If ParaView is not telling you that your data is image data or a uniform grid, then the data you write out will be necessarily incompatible with reading it as an image file.

Hello,

I'm new to Paraview and am trying to use it to edit a VTK image.  My
original image is in the structured points format.  I'm using the
ExtractCellsByRegion filter to select a subset, which I save using
Save Data with a VTK extension like the original.  However, I could
not open this file using the ITK ImageFileReader.  I believe this is
because the VTK file was saved as an unstructured grid instead of
structured points.

Does anyone know why this is happening and how to change it?  I can
look at converting it using ITK, but I'd like to know if there's a
better solution.

Thanks,
Sara
