I would be interested in doing this, I can probably create a doc that
outlines JP2/NITF C8 at a high level.
Most of the JP2 people I know (myself included) aren't doing JP2 anymore,
but it is a very useful format.

Even, Jukka,
the NPJE end EPJE specifications are both good for understanding
progression order in JP2. It all depends on what you are trying to do, so a
default is just that, something that can be changed.
A JP2 file with PLT markers (packet markers) in my experience removes most
of the overhead

Folks,
I don't know what's the amount of use of the Perl bindings, my feeling
is that it is not so much since there's not so much discussion on this
list or elsewhere. Anyway, I use them and want to develop them further.
Version 2.0 is chance to do some improvements, so I'm trying.

Hi,
It defaults to "LRCP". Is it really a good selection? JP2KAK defaults to
"PRCL" and JP2ECW to "RPCL" which both feels better choices than LRCP. But
perhaps it has been considered to be good for OpenJPEG because it must
practically be used with tiled output which may guarantee fast locational
