[Insight-users] ImageFileWriter not throwing exceptions

Hi Viet,


That's an interesting functionality to add
to the ImageIO classes. Unfortunately this
will have to be done class by class since
each one of them is very particular.

Most of the ImageIO classes use third party
libraries (png, tiff, jpeg, Meta).  We could
certainly add this feature to most of the ImageIO
classes whose full code is in Insight/Code/IO.

It will take a while to have it cleared over
all the platforms....

I would suggest you to enter this issue as
a "feature requrest" in the ITK bug tracker.

You can create yor own account at

      http://www.itk.org/Bug/

If you have already modified any ImageIO
writers in order to include this feature
we will be happy to give them a try on
the Dashboard and see how many platforms
support them. (It will be hard to setup
a nightly test for disk full though :-) )

Are you interested in a particular file
format at this point ?



Please let us know if you have further
questions,


    Thanks


      Luis
