NAME

       g3topbm - convert a Group 3 fax file into a portable bitmap

SYNOPSIS

       g3topbm [-kludge] [-reversebits] [-stretch] [g3file]

DESCRIPTION

       Reads  a  Group  3  fax  file  as input.  Produces a portable bitmap as
       output.

OPTIONS

       -kludge
              Tells g3topbm to  ignore  the  first  few  lines  of  the  file;
              sometimes fax files have some junk at the beginning.

       -reversebits
              Tells g3topbm to interpret bits least-significant first, instead
              of the default  most-significant  first.   Apparently  some  fax
              modems do it one way and others do it the other way.  If you get
              a whole bunch of "bad code word" messages, try using this flag.

       -stretch
              Tells g3topbm to stretch the  image  vertically  by  duplicating
              each row.  This is for the low-quality transmission mode.

       All flags can be abbreviated to their shortest unique prefix.

REFERENCES

       The standard for Group 3 fax is defined in CCITT Recommendation T.4.

       Probably.
