[Insight-users] ImageFileWriter not throwing exceptions

[Luis Ibanez]

Hi Viet,


This progress reporting was done with a simplified
version of the MetaImage reader that was used in
Code/IO at the time (june 2002).

In August 2002 we start using the MetaImage library
from the Utilities directory, just as we do with png,
jpeg and tiff now.  In this arrangement it is no longer
possible to invoke progress events from the readers since
the code in /Utilities is not aware of the existence
of ITK.

In order to get around this we will have to modify
the IO third party libraries to insert some sort of
callbacks, then provide such callbacks from the
respective ImageIO classes and translate the calls
into InvokeEvent() calls.

You are welcome to enter this also as a 'feature
request' in the bug tracker. I agree with you in
that this is a neat functionality to have. However
it may not make it to the top of the priority list.



Regards,


     Luis
