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.
