g3tolj
g3tolj(1) mgetty+sendfax manual g3tolj(1)
NAME
g3tolj - converts a Group 3 fax file into a printable HP-PCL file
SYNOPSIS
g3tolj [-kludge] [-reversebits] [-scale N] [-aspect N] [-resolution 75|100|150|300] [-compress 0|1|2] [-pagelength N] [-duplength N]
[g3file]
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.
REFERENCES
The standard for Group 3 fax is defined in CCITT Recommendation T.4.
