Cut and Paste Utilities
The next two utility commands, g3chop and g3combin, permit
cutting and pasting of fax images at the command line. These two
commands are most commonly used to create letterhead and
signature files.
Cut Utility (g3chop)
Removes portions of Brooktrout Group 3 fax files and stores them in
a separate file.
Command Syntax
g3chop -sx -cy -ifile1.301 -ofile2.301
Where:
For example:
g3chop -s5 -c20 -isalute.301 -oadvert.301
skips the first five lines of the file salute.301, chops the next 20 lines,
and puts them into the output file advert.301.
-s
(start chop) Specifies the distance in 1/10" units, from
the top of the file, to skip before chopping.
-c
(chop size) Specifies the distance in 1/10" units to chop.
-ifile1.301
(input file) Specifies the name of the file to chop.
-ofile2.301
(output file) Specifies the name of the output file which
contains the resulting chopped file.
-l
(lines) Changes the -s and -c arguments to work with
G3 lines as the units.
The number of lines are calculated in inches using the
file resolution if you know how far down in inches you
want to start and you use the -l argument: to skip 2
inches from the top of the file in normal resolution, skip
200 lines; for fine resolution, skip 400 lines.
The number of lines to chop can also be calculated based
on the file resolution and the number of inches to remove
from the file.
