I have an image 1-band with 16bit values,
and need to convert to a 1-band with 8bit values.

I like to have a linear conversion.
To have this is right the use of the

r.rescale command with to parameter "to=0,255"

Or should instead use however the r.recode command even if the
convertion is linear ?
