Re: jpm (multipage jp2)

IM relies upon the Jasper Delegate library for creating JP2000 image. 
So if the Jasper library does not support multipage JP2000 format 
(jpm), then you are probably out of luck.  That is described in 
http://www.digitalpreservation.gov/formats/fdd/fdd000144.shtml, which 
is JP2000 part 6 and I am not sure that Jasper goes beyond part 1 at 
this time.

see

But I will defer to the IM developers on this question.
