choptest - HylaFAX page chopping test program
/usr/local/sbin/choptest [ options ] input.tif
choptest is a program for testing the page chopping support in the
HylaFAX software (specifically, in the faxq(8C) program).
choptest analyzes 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 document, and what whitespace threshold to use in deciding if
a page should be chopped.
- -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 PageChopThreshold
configuration parameter; c.f. hylafax-config(5F). By default
choptest requires that at least 3 inches of trailing whitespace be
present.
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
