[Insight-developers] doubts regarding incrementing the operator

[Luis Ibanez]

Hi Aarthy,

The ITK image iterators do not provide the
API for integer arithmetics.

You should call the increment operator twice.

Just like

                           ++it;   ++it;

BTW, if what you are trying to do is to subsample
an image, you may be interested in looking at
the ShrinkImageFilter.


     Regards,


           Luis
