Hi Anna
Just an idea I got when using r.ctp2grass for some climate data.
Climate data layers are often multiplied by a factor 10 so they
can be distributed as integer rasters while still maintaining a
desired degree of precision. This made me think that it would be
nice if I could create a color rules file using r.ctp2grass with
the option to multiply the default values as defined in the ctp
file. Perhaps something along the lines of attached patch file for
r.ctp2grass (for illustrative purposes, I am sure things can be
done better)? Is that something that could be implemented?
Something similar could perhaps be nice for r.colors as well when
using one of the included color tables (but only those based on
values rather than percentages obviously).
Cheers,
Paulo
I can't really judge the usefulness of such option, but if you find it
useful, then go ahead and commit it. I would just use 'multiply' or
'multiplier', not 'multi' as the option name.
Hi Anna, I have been rethinking this option, and it is probably
something that is too specific. For linear scales, the -s flag will be
sufficient, while other color scales will often be tailored to specific
cases anyway.
Best,
Anna
