[GRASS-dev] r.cpt2grass - add option to multiply values

[Paulo van Breugel]

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
