[ITK-users] [ITK] bug in imageIOFactory

[Scott Pfeifer]

Bradley,
The solution I am using in my application has been to explicitly set the
ImageIO to the ImageFileReader so this is no longer a problem form me, I
just wanted to let everyone know this is an issue.  I appreciate your help
Thanks,
Scott
