[Insight-users] Bug or error in Docu

[Luis Ibanez]

Hi Gerald,

                 Thanks for pointing this out.

You found indeed a bug in the ITK Software Guide.


According to the CVS logs, I wrote incorrectly the text
of that table in June 2005.

The Doxygen documentation is the one that is consistent
with the implemented code.

I have just committed a fix to the CVS repository of the
software guide:
http://public.kitware.com/cgi-bin/viewcvs.cgi/SoftwareGuide/Latex/Transforms.tex?root=InsightDocuments&r1=1.54&r2=1.55&sortby=date


The online version of the PDF file is the most recent
version. We don't have immediate plans for updating
the ITK Software Guide.


       Luis

The strange thing is that all parameters except the last is 0, the last one is 1. That means that the scaling is 0 and the translation in z is 1 (referring to the doku)?
