Bitmap Compression class

Ok, I have written code to load a BMP including palette data and image data. To be compatible with the program I am writing for I need to take the image data piece only and compress it using an algorithm as follows

"Algorithm: use open addressing double hashing (no chaining) on the prefix code / next character combination. We do a variant of Knuth's algorithm D (vol. 3, sec. 6.4) along with G. Knott's relatively-prime secondary probe. "

Does anyone know if there is a class out there that will compress the raw image data using this algorithm.

Thanks Andrew
