⚠️Vincent: added a trick to handle GRASS color rules export to QGIS

	You can then copy the resulting .svg file into <tt>/usr/share/qgis/resources/cpt-city-qgis-min/grass/</tt> on Linux (or <tt>C:\Program Files\QGIS VERSION\apps\qgis\resources\cpt-city-qgis-min\grass\</tt> on MS Windows).

			Another solution to export raster color tables is to slightly tweak the output of {{Cmd\|r.colors.out}}, in order to provide QGIS with a regular color chart source file. It might be handy when dealing with maps produced by {{Cmd\|r.composite}}, i.e. unregistered color charts. The example bellow may be adapted to ones needs (here the alpha channel defaults to 255):
			<source lang="bash">
			r.colors.out map=my_raster rules=~/in.colors
			cat in.colors\|sed 's/:/,/'g\|sed 's/ /,/'g\|awk 'BEGIN {FS=",";OFS=","};{print $1,$2,$3,$4,255,$1}'>out.colors
			</source>

			Currently the GRASS 6 addon module {{AddonCmd\|r.cpt2grass\|version=64}} seems to hit a bug, but the general idea is to use the ''svgx'' command line program from the <tt>cptutils</tt> package, using [[GMT]]'s .cpt color table format as a go-between:

			<source lang="bash">
			svgx --output dkbluered.cpt --type cpt /usr/share/qgis/resources/cpt-city-qgis-min/h5/dkbluered.svg

	Most of them can already be found there, you just have to hunt for them. In the raster layer properties window's style tab, select "Singleband pseudocolor" as the type, "Generate new color map", "New color ramp", for ramp type choose ~~the~~ "cpt-city", change to the ~~sort~~ by ~~author~~ tab, and look for "grass".

	If there's a new set of color rules which are not in [[QGIS]], you can prepare a .svg palette file for use with QGIS using the following commands. Consider to then open a ticket in the QGIS issue tracker asking them to add it (and attach the file of course to save someone some work :)		If there's a new set of color rules which are not in [[QGIS]], you can prepare a .svg palette file for use with QGIS using the following commands.
