[Insight-users] Capturing progress info while loading file

[Luis Ibanez]

Hi Yann,

You are right,

the ImageIO was not invoking ProgressEvents.

I just modified the MetaImageIO class in order
to invoke ProgressEvents.

It was originally reading the whole image in
a single Read(char *buffer, imagesize) operation.

Now this has been divided into 100 reads() and
in between them, ProgressEvents are invoked.

The GaussianFilter example (3D) has been modified
in order to reflect these updates.

If you CVS update now, you will be able to get the
updated version of IO.


Please let us know if you find further problems.


Thanks for your feedback.


    Luis
