[ITK Community] ITK set pixels in a loaded image/Quickview

[Annabelle Dupuis]

Thanks Matt for your awnser but I finally solved it.
However I have another question.

I'm actually doing some segmentation so I started apllying a median filter and a threshold on my image made of 'unsigned short'.
The probleme now is that when I want to apply th morphological filters nothing happens unless If I use an 'unsigned char' image data from the begining wich mess up all the threshold filter.

Is there any way to convert an unsigned short image data to an unsigned char?

Thank you guys
