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 out-
    put.

OPTIONS
    -kludge
    Tells g3topbm to ignore the first few lines of the file;  some-
    times 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.

BUGS
    Probably.
