[vtk-developers] Problem of how to get the dimension of a picture

[Joachim Pouderoux]

What do you mean by "is wrong"? Are the returned values in the orignalDims
array incorrect or do you have a compilation error?

If the returned dimensions are incorrect, please provide an image example,
what are expected dimensions and what are the one returned by GetDimensions?
