DESCRIPTION¶
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.
OPTIONS¶
- -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.
