[gembud] GEMPAK Help needed

Hello,
I could use some help ..
I have been scouring the GEMPAK user files for the better part
of the day, with no sucess on how to convert the NIMAGE feed
West and East Conus to either png or jpg (jpeg) ..

I played with the zlibg2gini and with sucess was able to decompress
the files, but am a bit lost on what to do afterwards ...

any sugestions would be appreciated ..
For the sake of it in case asked here are my ldmd.conf and pqact.conf


REQUEST NIMAGE "SUPER-NATIONAL|EAST-CONUS|WEST-CONUS"   bigbird.tamu.edu:388



NIMAGE ^satz/ch[0-9]/.*/(.*)/([12][0-9])([0-9][0-9])([01][0-9])([0-3][0-9]) ([0-2][0-9])([0-5][0-9])/(.*)/
(.*km)/
       PIPE    -close
       decoders/zlibg2gini -vl logs/ldm-mcidas.log
       data/sats/raw/\8/\9/\1/\1_\2\3\4\5_\6\7

Thanks
