[Insight-users] 32-bit PNG input trouble

[Zachary Pincus]

Hello,

I noticed that the file reader doesn't appear to deal properly with 32 
bit PNG files. Perhaps this is by design, however, in that case trying 
to read in such a file should raise an exception.

Here is simple test code (it just reads a file to unsigned char, and 
writes it again) and a couple 32-bit png files which this code garbles, 
either by inverting the image, or just breaking it entirely:
