[GRASS-dev] Rast_add_d_colour

[Yann Chemin]

Hi,

I am working on beautifying the output of i.theilsen, a new addon.

For some reason, I cannot apply a grayscale palette.
---------------
Rast_init_colors(&colors);
DCELL val1 = ts_min;
DCELL val2 = ceil(ts_max);
Rast_add_d_color_rule(&val1, 0, 0, 0, &val2, 255, 255, 255, &colors);
---------------

ts_min, ts_max are known from the data processed,
val1 and val2 are declared as DCELL instead of const DCELL as required,
but if I declare const DCELL val1, then I cannot write stats to it for
palette definition...

What I am doing wrong?
Yann
