Detailed Description

Image File Type to read/write and store/restore Image objects as JPEG-2000 data.

To be able to load JP2 images you need the Jasper library. The lib comes with all Linux distributions. http://www.ece.uvic.ca/~mdadams/jasper/

You have to --enable-jasper in the configure line to enable the singleton object.
