[Insight-users] Tiff reading problem

[Julien Jomier]

Hi Nicolas,

The TIFFImageIO class was not supporting 16bits PALETTE_RGB images.
I've just checked in a fix in the cvs repository and I'm able to read 
your image using a pixel type of unsigned short.

Let me know if that works for you or not.
Thanks for the report,

Julien
