[Insight-users] Tif RGB wrong way around?

[John Biddiscombe]

Thanks. I should have thought of trying that! I'll look for a mistake in my
code somewhere.

Hi John,

I just tried to read a RGB tiff image and write it as JPEG and BMP using ITK
and the resulting image appears to be valid so I guess the channels are in
the correct order when reading the file.

Hope this helps,

Julien
