[GRASSLIST:4046] GIMP & GRASS?

[Du Chavoux luyt]

Hi

1. I've read about using Photoshop together with GRASS 
(http://www.pdcarto.com/mtncarto02/GRASS.htm) and would like to know if 
there is any tutorials or documentation for using GRASS together with 
the GIMP... spesifically in what format to export GRASS raster files to 
GIMP and how to get them back into GRASS without losing their 
"georeferencing".

2. If anybody has some experience using these 2 programs together, I'd 
like to know which is easier to use for supervised classification. I 
know that the threshold tool (or to a lesser degree the "magic wand") 
can be used in the GIMP for this purpose, I'm still reading the GRASS 
manuals to find the tool to use for this.

Thanks
