Subject: gis.m: intelligent defaults for d.rast.arrow
Hi,
The new gis.m makes it easy to use d.rast.arrow, but the defaults are all
wrong for the typical gis.m experience.
suggestion:
calculate the canvas size in pixels as well as the region size, then calculate
what gives you an arrow every 8-12 pixels.
set the arrow scaling to about 2 times the grid spacing.
set the grid color to "none".
It will be nice for these things right out of the box whenever possible.
Is it possible? (then what happens on resizing monitor or zoom?)
thanks,
Hamish

I'll see if there is a way to set these as defaults.
Why can't grid color = none be the default on the underlying C module?
It might or might not be complicated for the arrow spacing. D.rast.arrows is
not designed to make dynamic arrow spacing (a flag to add???), so I suppose
that you would have to reset it all manually if you zoomed in or out.
