Dear all,
I've got a view questions about plotting with the cairo driver. Is there a way to overlay rasters with d.rast? Somehow the -o flag dosen't seem to work when using the cairo driver. Is it possible to plot an overlaying raster in a transparent way? And can I change the size of d.barscale in a high quality plot?
Many thanks,
Niklas

It doesn't work in 6.x; r40501 needs to be back-ported.

No. d.barscale chooses the size based upon the physical dimensions of
the visible region.

really, if you want a high quality plot in GRASS 6 (for printing)
you will want to use ps.map, or ps.output (from addons). Then
paste in the EPS file, tweak with Inkscape or Adb. Illustrator, ...
for a large graphic on a poster or projector presentations the
d.* display outputs can be ok, but as you discovered this is
primarily designed for on-screen display so many things like
d.barscale, d.rast.arrow, and d.grid are hardcoded with lines as
one pixel wide. The d.mon PostScript driver may be easier, but
you may have to use GRASS 7.svn to get good results there.

Done for 6.4.svn and 6.5.svn.
