It is interesting to know about the differences in vtkMassProperties for VTK 5.04 and VTK 5.4.2

I have a little function

Note

Checking both VTK-5.4.2 and VTK-5.2.1, I narrowed the situation a bit and I think that this behavior was introduced between versions 5.0.4 and 5.2.1.

Update

In VTK-5.4.2, it seems that vtkTIFFReader ignores the x and y values ​​set in the SetDataSpacing method. Instead, vtkTIFFReader computes x and y dataspacing from the resolution reported by the TIFF files.
