[GRASS-dev] [bug #5432] (grass) gis.m: display option (e.g. contrast stretch)

[Michael Barton]

The GUI is built using existing GRASS commands. The raster display panel
uses d.rast and d.his to produce the display options. There is no option in
d.rast (or d.his) to control the display in the monitor like you are
suggesting (though this could be nice).

The only way I can think of to do what you request is to wrap in r.colors
into the display panel. However, this would change the color table for the
map. That is, this would be the new default color table until you select a
new color table. A button to launch r.colors might be handy, though it's
pretty accessible from the menu too.
