Summary0002443: add a run-time warning when trying to save a transformed .vtk file
Description

There is a loss of information when saving a transformed .vtk image as this format doesn't support the concept of an affine tranformation from index space to physical space.

There is a warning in the documentation, but a run-time warning would be a helpful feature.

(http://wiki.slicer.org/slicerWiki/index.php/Documentation/4.1/SlicerApplication/SavingData#Supported_formats)

To reproduce this:

  • download the MRHead dataset
  • apply any rigid linear transform
  • harden the transform
  • save the volume as .vtk
  • reopen the transformed volume and it appears elsewhere in space (not
    in the original position and not in the desired tranformed position)
TagsNo tags attached.

Maybe we could make something like a 'lossy' attribute of the storage classes so that when they are selected in the save dialog they generate a warning?
