Hi all;
I'm getting beautiful maps to be used in a presentation. And I'm usin "black"
as background color. So, when I want to display a map (this is a coastal
area) I use:
d.rast -o rastermap
In this way, null values are not displayed, and all cells belonging to sea
area black as the background.
The problem is when I use d.his, because this command doesn't allow to use a
color for nulls or to use -o to do nothing with nulls.
So, my question is:
Is it possible to get a new map with the output of d.his?
Or
Do you have any idea about how get a whole black background (including nulls)
with d.his?
Best regards
Javier

Yes, with r.his.

If you have the source, the attached patch makes "d.his -n" behave
like "d.rast -o".

Hello javier,

I wrote a module, which does this.
But be aware, that the resulting Map is only for diplaying-purpose,
because the colors are reduced, so further anaysis on this maps be
generalized and maybe wrong...
Basicly this script mainly combines r.his and r.composite in one
command.
