Produces a portable bitmap as output.\n\n### OPTIONS\n\n#### -kludge\n\nTells g3topbm to ignore the first few lines of the file; sometimes fax files have some\njunk at the beginning.\n\n#### -reversebits\n\nTells g3topbm to interpret bits least-significant first, instead of the default  most-\nsignificant  first.   Apparently  some  fax  modems do it one way and others do it the\nother way.  If you get a whole bunch of \"bad code word\" messages, try using this flag.\n\n#### -stretch\n\nTells g3topbm to stretch the image vertically by duplicating each row.   This  is  for\nthe low-quality transmission mode.\n\nAll flags can be abbreviated to their shortest unique prefix.\n\n### REFERENCES\n\nThe standard for Group 3 fax is defined in CCITT Recommendation T.4.\n\n### BUGS\n\nProbably.\n\n### SEE ALSO\n\npbmtog3(1), pbm(5)\n\n### AUTHOR\n\nCopyright (C) 1989 by Paul Haeberli <paul@manray.sgi.com>.\n\n\n\n02 October 1989                                g3topbm(1)\n\n"
