[Insight-users] Parameters of ScalableAffineTransform

[Hendrik Belitz]

Hi, fellow ITK users,

I am using the itk framework for some simple 2D affine registrations and I'm 
wondering if my interpretation of the final transformation is correct.

itk::ScalableAffineTransform for 2D images of type double returns 6 
parameters. Is it right that the first two parameters represent the 
translation of the moving image, while the latter four are a representation 
of the rotation/scaling matrix?

Regards
 Hendrik
