g3topbm(1) Unix Programmer's Manual g3topbm(1)
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.
BUGS
Probably.
