range.tgz
I have also made a fast and easy to use rangecoder (source code in C). It can compress as good as the old CACM arithmetic coder but 2-4 times faster! The latest modifications 13 january, 2002.

The main difference in this range coder compared to others is how the cumulative frequency, cumFreq, is calculated. The start of a symbol's range in the total range is then known which is necessary to encode it.

It's simple, it just remembers what the last symbol was and cumFreq and then decides if it should start calculating what is to be added or subtracted to cumFreq, from the remembered value, the beginning of the frequency table, or from the end of the frequency table, depending on which is the closest.

Read the documentation in the archive for more about usage.

I've developed and compiled a Windows executable of a Burrows and Wheeler's Transform (BWT) compressor.

Translation tools
I'm the author of the two translation tools between Xfig and Framemaker mif format documents. I created these two tools when I were doing my xjob, finishing studies at the university in Linköping.
