JPEG2000 support?

I've also been using ImageMagick to do some conversions.  (In fact, I'm going
to try it soon to see if it can handle converting a ~12GB image without first
loading it all into memory.)  I was hoping that PyMagick might be able to
also handle JPEG2000.

A few days ago when I was searching for this information I recall seeing that
someone was having problems using ImageMagick for JPEG2000 because he could
not find a way to specify some of the JPEG2000-specific features.  I will
need to be able to, for example, set the progression order for creating
JPEG2000 images but I'm o.k. with creating the image with something else.

It's vital, however, that I find a way to extract images efficiently.  When I
timed ImageMagick by using "convert" to extract various resolutions of a
JPEG2000 image (simply using "-scale"), it was not clear to me that it was
taking advantage of JPEG2000's multi-resolution capabilities.

Thank you for the reference.  I'll try a PyMagick implementation.  (I would
have done it sooner but it's not a Debian package.)
