This is probably a question for Frank W.. I'd like to re-write the raster classifier in Mapserver so that it can apply a linear color gradient using LUTs. I've got code written already to do this with the Python API to GDAL, and would like to be able to do the same thing in Mapserver. Can someone point me to the right C code?
Roger, The core of the existing classification logic is msGetClass() in mapraster.c. Also if you search on "classified" in mapdrawgdal.c you will see most of the places it gets used. I believe that ramp based gradients should be written up as an RFC. There was a previous effort which I think was partially implemented. I would suggest you dig up information on it, before going too far. http://mapserver.org/development/rfc/ms-rfc-6.html Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, warmer...@pobox.com light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
