File opens fine in Seamonkey
Can open the file fine in GBM Viewer or editor though its a bit slow but then it is over 20M in size.
Converts fine to JPG in GBM Editor.
The GBM I'm using is the latest one, wonder if its something to do with the j2kcodec_134.zip file, I have the exe's from this package in my path.
See attached screen grab
PS,
However, I was hoping to find some means to manipulate the image as well.
Best option after a bit of messing around is convert to TIF with GBM then edit in PMview or another
editor with options to suit.
