Subject: System Response when no colortable is present

Platform: GNU/Linux/i386
grass obtained from: CVS
grass binary for platform: Compiled from Sources
GRASS Version: CVS

Dear developers,

not really a bug, but a proposal for a message when importing Raster-maps without
colortables. The Problem appears when importing a rastermap without a proper
colortable. When trying to display this map, nothing appears on the screen even
when setting the region to the imported map. The system should then give a message,
that no appropriate colortable is present and give a hint to using r.colors.
Especially for new users it might be a great help so that they can be sure, no
errors occured during import and they additionally should set a colortable.
Cheers
        Stephan Holl

A map with no defined colour table should automatically use the
"rainbow" colour table.

If this isn't happening, file a bug report with details of how to
reproduce the problem.

It happened to me the other day.
v.in.ascii to get points data then v.to.rast to convert to a raster.
There were some points that appeared (about 4 out of thousands).
I was really wondering if v.to.rast actually works in 5.7 till I tried 
r.colors and it suddenly appeared.

Regards
Gordon

That's a separate problem; v.to.rast explicitly sets a random
colourtable.

In the test cases I've tried, it seems to work ok. If you know of a
case which doesn't work, please submit a bug report with sufficient
details to allow reproduction.
