[Insight-users] Capturing progress info while loading file

[Luis Ibanez]

Hi Yann,

You are right, invoking the events from the
ImageIO class is not enough since the
visible object is the ImageFileReader or
the ImageFileWriter.

The solution seems to be to make the
ImageFileReader and ImageFileWriter
Observers of their own ImageIO objects.
and make them re-throw the events
comming from the ImageIO objects.

I'll add this to the code and let you
know when is ready.
