[GRASS-user] d.vect not using RGB values in attribute table

[Huidae Cho]

Interesting...  Were these polygons displayed correctly before I added wcolumn=
and wscale=? Or is this the first time you use -a for this map?  try to insert
the following line just above "} /* end if table_colors_flag */" in area.c:

fprintf(stderr, "colorstring:: area=%d cat=%d rgb=%d r=%d g=%d b=%d\n", area, cat, rgb, red, grn, blu);

and run the same command.  If you don't mind, could you send me (without CC to
the list) a copy of the map?
