[GRASS-user] Make transparent null data.

[Luis Miguel Royo Perez]

Hi everyone,

maybe the question is not difficult, but i couldn't find the way to make 
null data transparent, i've been reading the documentation, but still i 
can't found the answer, if anyone could help me i'll apreciate a lot.

Just indicate the name of algorythm that makes this and i'll study the 
documentation.

Thank you.
