[Qgis-user] colour gradients

[Giovanni Manghi]

Hi,
color ramps for vectors are now available if you use the new symbology.

Ramps for rasters in qgis are still missing (there is a ticket open in
the trac) but you may want to import them into a GRASS mapset (you can
do it trough (QGIS) and the use the r.colors.table were you can find a
good number of ramps available.

cheers
