Hi Mark,

If I understand correctly, you've got the complete transformation matrix
(with e.g. pfGetDCSMat) and also the rotation matrix.
Mathematically you should be able to get the scaling if you do the
following: Multiply the complete transformation matrix with the
inverse rotation matrix. Then you should be able to retrieve the scaling
values from the diagonal elements of the resulting matrix.

Cheers,
Sven
