pbm2g3: convert portable bitmaps (PBM) into G3 fax files
pbm2g3 - convert portable bitmaps (PBM) into G3 fax files
SYNOPSISpbm2g3 [-r] [-w<pagewidth>] [-h<blanklines>] [-d] [-a] [pbmfile]
DESCRIPTIONReads a portable bitmap as input, converting it into a G3 fax file on stdout. That file is suitable for faxing it with sendfax(8) or queueing it for faxing with faxspool(1) (provided that it gets a ``.g3'' suffix).
- byte-aligns the end-of-line codes, inserting padding bits as necessary.
- -w <page width>
sets the width of the resulting G3 page. Default is 1728. If you want to
be able to fax it with sendfax, don't use anything else. For other fax
programs, 2048, 2432, 864 and 1216 may be useful. For other purposes, use
what you like.
If you set it to 0, the width of the pbm file will be used.
- -h <blank lines>
specifies the number of blank lines
should prepend to each page. Default is 0.
To produce identical output as pbmplus' pbm2g3 program (with my patch!) does, use ``-h 4''.
- reverse the bit order in the bytes.
will one day make pbm2g3 prepend a digifax header to the page.
REFERENCESThe standard for Group 3 fax is defined in CCITT Recommendation T.4.
BUGSThe -d option isn't implemented yet.
