SYNOPSISsff2g3 [-r] [-d] [-v] input.SFF output.%03d.g3
DESCRIPTIONReads a Common ISDN API (CAPI) structured file format (SFF) input file, and converts every fax page contained in it to a raw G3 fax file.
The input SFF files typically come from fax reception programs using CAPI on active ISDN cards (isdn4linux, AVM or DIVA cards) or similar. The output G3 files are in the ``native'' format that all other G3 utilites in the mgetty+sendfax package use.
If the input file name is ``-'', sff2g3 will read from stdin.
- reverse the bit order in the bytes of the output G3 file. The input bit order is fixed.
- will one day make sff2g3 prepend a digifax header to the page.
verbose mode - show what's going on. Multiple
arguments increase debug output level.
REFERENCESThe standard for Group 3 fax is defined in CCITT Recommendation T.4. The SFF file format is specified in the CAPI specs (http://www.capi.org).
BUGSThe -d option isn't implemented yet.
The output file name is not yet robust against format string attacks.
