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.

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