I believe I have written and read 16 bit png files with ITK. I definately
know that I have written them. And I think I have read them back into ITK.
Did you change the pixel type on the ImageFileReader when switching from 8
bit to 16 bit images?
Are you confident your 16 bit images are "good" png files?

Hi,
I have a number of 16-bit grayscale .png files that I wish to process using
ITK. When using the itkImageFileReader class to read them in, the following
message occurred
This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.
This program works fine with the 8-bit .png file.
Does anyone know if the .png 16-bit support in itk works?
Thanks!
