[Insight-users] *Can* run the example Image5 after building (cvs source)

[Luis Ibanez]

Hi Robert,

I agree with you that this would be a nice feature
for figuring out the cause of the exception.

This could be done by having the ImageIOFactory
collect lists of supported extensions, and holding
them in an internal list.

Note however that not all readers are based on
extension. Some of them use magic numbers or
other heuristics in order to determine if the
passed file correspond to its known file format.

The criteria for accepting/rejecting a file is
left to the specific ImageIO object. Some of them
use the extensions, some others don't.  At this
point it is not clear if a uniform mechanism is
possible.



   Regards,


      Luis
