* [FOD] Changed the ROI parameter in the image_to_j2k codec to make it correspond to the documentation (i.e. -ROI c=0,U=25)
October 12, 2007
* [FOD] Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard.
This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter)
