Initial Comment: as reported on the mailing list: http://article.gmane.org/gmane.comp.gis.grass.devel/22645 There seems to be a bug in r.colors in 6.2 and 6.3. e.g. for a CELL map containing values of [0-255], if the rules file looks like this: 0% 0:0:0 37.5% 255:0:0 37.5% 255:0:0 75% 255:255:0 75% 255:255:0 100% 255:255:255 the colr/ file looks like this: % 0 191.25 0:0 95.625:255:0:0 95.625:255:0:0 191.25:255:255:0 ie the last 100% rule is forgotten. Same if I give it real values: G63> r.colors gebco_bathy col=rules << EOF > 0 0:0:0 95.625 255:0:0 > 95.625 255:0:0 191.25 255:255:0 > 191.25 255:255:0 255 255:255:255 > EOF WARNING: Your color rules do not cover the whole range of data! (rules 0.000000 to 191.250000 but data 0.000000 to 255.000000) ??? the usual way to give percentage is typically 1 rule per line, which is why we haven't noticed this before: 0% 0:0:0 37.5% 255:0:0 75% 255:255:0 100% 255:255:255 ---------------------------------------------------------------------- You can respond by visiting: http://wald.intevation.org/tracker/?func=detail&atid=204&aid=508&group_id=21 _______________________________________________ grass-dev mailing list [email protected] http://grass.itc.it/mailman/listinfo/grass-dev
