Accessing all resolutions in a JPEG2000 image
Does this bug mean that it's impossible to access all resolutions inside a JPEG2000 image? http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6175316
For example if I open a JPEG2000 image in Photoshop it asks me which resolution I'd like to open it in: 1280x1024, 640x512, 320x256, 160x128, 80x64, or 40x32
Is it possible to:
1) Find out what resolutions exist?
2) Open an arbitrary resolution on demand?
The obvious benefit here is that I could get at a reduced-size resolution without having to scale the image.
