Since it deals for the most part about graphics (and colormaps), I think it's the appropriate forum. If not, well sorry for the inconveniance.I have finished a doc about the use of the transform / invtrans / transformcolor columns we can find in some .txt files. I have give the links to phrozenkeep for some days, but they may have bigger occupation than to put it into (or maybe there's only 1 update of the site per week, and the doc will appeared only then, if I have understodd correctly). I tall them I was not hurried, which is still true, but finally, while it is not published, I can still modified it if some of you think there are things to be made in it. I never saw some doc dealings with this in the keep's tutorials/ressources.
the doc itself is at http://paul.siramy.free.fr/_divers/colormaps.zip (5 kB, a simple html page)
while a program that can be used for test of it is at http://paul.siramy.free.fr/_divers/dc6color.zip (187 kB, usefull tool, with source)
Any suggestions are welcome. Thanks.
