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 output.


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.
