I'm a developing an application using jasper library and i need to encode ROI some ROI (region of interest). I read in the jasper official website https://www.ece.uvic.ca/~frodo/jasper/ that, only the decoder support ROI. But i saw in the jpc codec source code https://github.com/mdadams/jasper/blob/master/src/libjasper/jpc/jpc_cs.h a field call "roishift".
Did someone know what it is for?
Thank you for your answer!
