JPEG-LS is a lossless image compression algorithm for continuous-tone images. Images compressed using JPEG-LS results to a file with an extension of ".jls". How may I access this file, or how may I access its bitstream, so that I may further compress it? Access it in a programming language, e.g. (C#). I'd like to maybe save the bit stream maybe in a string, or so. e.g. string s= bitstream. And from then on, I may compress it.
