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.
