- 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.
