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!

jasper is a dead project. It is no longer consider an active reference JPEG 2000 implementation, why would anyone use japser these days ?

OpenJPEG does implement the simple ROI upshift a whole component, if you can pick an active JPEG 2000 implementation.
