Can anyone confirm that this is a real bug? Or does it come from
not
using d.rast first? (AFAICT, d.rast.num draws the text in either
black
or white, depending upon whether the cell is light or
dark
respectively).
In any case, there should probably be an option to set the
text
colour, so that d.rast doesn't have to be used first. |

Yes i can confirm this behaviour. d.rast.num works if one draws the raster
first with d.rast. Obviously the text colours have to be either white (lighter
than background) or black (darker than background), d.rast.num checks for the
colour of the backdrop cell before drawing (white or black). But this
obviously only works correct if you draw the numbers on the same raster. If
one selects a different raster for backdrop the text number may be unredable.
In the source there is a part commented out that selects the colour. Perhaps
someone can tell if the old algorithm is better?
