Patch Set 2: Fails

Tests are failing

Patch Set 2:

Next patch set allows some more tests to pass, but I do not know if it is the write thing to do. We should try to get backwards-compatible behavior if possible.

Patch Set 3: Do not submit

Must maintain backward compatibility

Patch Set 3:

As I mentioned in an earlier e-,ail, pHYs measures pixel size/aspect ration. sCAL is the proper parameter to change, but as you pointed out, ITK is not writing out a correct sCAL unit type. Since ITK does not have a concept of unit, I think we just need to repair the output image to specify a valid unit type, which probably should be meters rather than radians.

Patch Set 3: Abandoned

This is more than a year old with out any progress on a resoution. If something will be done to address the raised concerns, then re-open the patch.
