JLM library and utilities
-------------------------------
A JLM file is a dct-compressed lightspace map. If you are unaware about lightspace maps, do a google search on lightspace. As this document matures, I plan on including specific references to this research area.
However, regular lightspace maps are double-precision values representing photoquantimetric readings from a light sensor (such as a camera). These files are usually quite large and are not easily compressible by a utility such as "cjpeg" which is meant to work on 8-bit unsigned char values.
This library and the associated utilities are designed to give JPEG-like DCT compression to lightspace maps.
Examples to follow.
