Subject: Add like option in clitkExtrude tool
X-Git-Url: https://git.creatis.insa-lyon.fr/pubgit/?p=clitk.git;a=commitdiff_plain;h=22aac696ea46e2e4f989d8893bcb978f63715aef

Add like option in clitkExtrude tool

Before we had to set size, spacing and origin for the new dimension
But we could want to have the same size, spacing and origin than another image.
So I add the like option

I remove the required for the size option because if like is set , size is not mandatory
I controled that like and origin, size or spacing are not set at the same time
