#170: r.colors: make nice random colors like r.watershed --------------------------+------------------------------------------------- Reporter: hamish | Owner: [email protected] Type: enhancement | Status: new Priority: minor | Milestone: 6.4.0 Component: default | Version: svn-develbranch6 Resolution: | Keywords: r.colors --------------------------+------------------------------------------------- Comment (by glynn):
Replying to [ticket:170 hamish]: > r.watershed has some color rule creation code it in which makes the random rules not quite pastel in nature, but cool. it's a lot more pleasant than r.color's color=random method. > > see the r.watershed examples here: > http://grass.osgeo.org/screenshots/raster.php > > it would be nice to move that rule generation code into libgis and then add a new "r.colors color=random_cool" or similar option. > (and simplify r.watershed in the process) If I'm reading the code correctly, it creates a set of random colours, then replaces any dark colours with non-random colours selected from generated gradients. IOW, it's a fudge which shouldn't be elevated to a library function. If you just want to eliminate dark or saturated colours, it would be preferable to add transformation functions to adjust and/or clip the intensity, saturation and hue, which could then be applied to any existing colour rule, not just random colours. -- Ticket URL: <http://trac.osgeo.org/grass/ticket/170#comment:2> GRASS GIS <http://grass.osgeo.org>
