[GRASS-user] Re: Conversion of multiple rasters to PNG files

[Mortsde]

Daniel,

Thanks for that write up. I just wanted to ask what the purpose of the /tmp/
line was. It seems like the conversion ran through just fine, but I don't
see any of the files saved to a specific place. Is the "/tmp/" listing the
folder directory where the files are written?
