[Qgis-user] How to reclassify?

[Etienne Tourigny]

I don't know how to do it in QGis, but I do it with a python script
using the GDAL Python bindings and numpy.

It's a little slow but works well, and I use a csv file to write the
mapping values.
The code is not very clean, but I could post it if you like.
