CHOPTEST(8C) CHOPTEST(8C)
NAME
choptest - HylaFAX page chopping test program
SYNOPSIS
/usr/sbin/choptest [ options ] input.tif
DESCRIPTION
choptest is a program for testing the page chopping support in the HylaFAX software (specifically, in the faxq(8C) program). choptest ana-
lyzes a TIFF/F (TIFF Class F) file with 1-D MH- or 2-D MR-encoded data and reports what the automatic page chopping logic would do if the
file were submitted for transmission. Options are provided for controlling whether choptest checks the last page or all pages of the docu-
ment, and what whitespace threshold to use in deciding if a page should be chopped.
OPTIONS
-a Chop all pages in the document. This is equivalent to setting the PageChop configuration parameter to ``all''; c.f. hylafax-
config(5F). By default only the last page of the document is considered.
-t inches Set the minimum whitespace threshold that must be present on a page for it to be chopped. This is equivalent to the Page-
ChopThreshold configuration parameter; c.f. hylafax-config(5F). By default choptest requires that at least 3 inches of trailing
whitespace be present.
EXAMPLES
The following shows a multi-page, high-resolution document. Each page has insufficient whitespace for it to be chopped.
hyla% ./choptest -a ~/tiff/pics/faxix.tif
Chop pages with >=3" of white space at the bottom.
Don't chop, found 67 rows, need 588 rows
Don't chop, found 67 rows, need 588 rows
Don't chop, found 67 rows, need 588 rows
Don't chop, found 53 rows, need 588 rows
Don't chop, found 91 rows, need 588 rows
Don't chop, found 99 rows, need 588 rows
Don't chop, found 47 rows, need 588 rows
