Hi Bill,

Thaks for your reply. I don't think we have expressed any issues about 
the exception itself, but motes said that he's defining the PixelType as 
unsigned char/short, yet writing the data fails.

Oh! Is this a problem with any of the intermediate steps changing the 
pixel type?

On a related note: Where is the method GetComponentType() called by 
PNGImageIO::WriteSlice declared? I'm sure it's very obvious where it is, 
but I have been searching for it in the ITK code (grep and [1]), and I 
couldn't find it.

Cheers,
