g3tolj - converts a Group 3 fax file into a printable HP-PCL
file
g3tolj [-kludge] [-reversebits]

[-pagelength N] [-duplength N]
[g3file]
Reads a Group 3 fax file (raw or digifax) as input. If no filename
is given, stdin is used. Produces a printable HP-PCL file as output.
- -kludge
- Tells g3tolj to skip the first lines for synchronisation.
- -reversebits
- Tells g3tolj 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
"invalid code" messages, try using this flag.
- -scale N
- Scale the output to match the printer resolution and paper size, the
default of 1.40 will do in most cases.
- -aspect N
- Scale the output to match the printer resolution and paper size, the
default of 1.0 will do for high resolution faxes, 2.0 will do for low
resolution faxes.
- -resolution
75|100|150|300
- Selects print resolution. The default is 300.
- -compress
0|1|2
- Selects compression method for the print output. 0 = none, 1 = rll, 2 =
tiff. The default is 0.
- -pagelength
N
- Defines the pagelength in inches, the default is 10.95. After this length
a pagebreak is generated and the last part of the previous page is
duplicated on the next page
- -duplength
N
- Defines the length in inches that will be duplicated after a pagebreak,
The default is 0.7.
The standard for Group 3 fax is defined in CCITT Recommendation
T.4.
