[Insight-users] Problem with FloodFilledFunctionConditionalConstIterator

[Luis Ibanez]

Hi Mathias,


Thanks for pointing this out.

The code in

  FloodFilledFunctionConditionalConstIterator::InitializeIterator()

has been modified according to your suggestion.

The tempRegion is now equal to the LargestPossibleRegion().
a CVS update should give you the new version.


Please let us know if you find further problems,


Regards,


    Luis
