g3topbm - convert a Group 3 fax file into a portable bitmap
g3topbm [-kludge] [-reversebits] [-stretch] [g3file]
Reads a Group 3 fax file as input. Produces a portable bitmap as
Tells g3topbm to ignore the first few lines of the file;
sometimes fax files have some junk at the beginning.
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.
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.
