Hi I have been meaning to post this for a while, It is some source for a logoPainter that I made for an upcomming bioinformatics paper regarding the correction for signals in a biased genome.
It is based on a Biojava-live (although perhaps a slightly earlier
release so it made need the odd tweak) Anyhow it demonstrates some writing
to Jpeg Tiff bmp etc. Uses the Java Advanced Image Library (JAI 1.1 from
Sun). Please feel free to use / review the code as you see fit. Perhaps
ask permission before selling it ;)
I would be happy for it to be made part of the CVS if people want. It
could probably do with some peer review so to speak as it has a few rough
edges in the code that others might be able to make more elegant.
Enjoy
Mark
