CQTEST(8C)CQTEST(8C)NAMEcqtest - HylaFAX copy quality checking test program
SYNOPSIS
/usr/sbin/cqtest [ options ] input.tif
DESCRIPTIONcqtest is a program for testing the copy quality checking support in
the HylaFAX software (specifically, in the faxgetty(8C) program).
cqtest takes a TIFF/F (TIFF Class F) file and generates a new TIFF/F
file that is a copy of the input file, but with any erroneous scanlines
replaced/regenerated. In addition, cqtest prints diagnostic messages
describing its actions and indicates whether the input data has accept‐
able copy quality according to the copy quality checking threshold
parameters. Options are provided for specifying copy quality checking
threshold parameters
OPTIONS-m badlines Set the maximum consecutive bad lines of data that may
appear in each acceptable page of input data. This is
equivalent to the MaxConsecutiveBadLines configuration
parameter; c.f. hylafax-config(5F). By default cqtest
accepts no more than 5 consecutive bad lines in a page.
-o file Write output to file. By default output is written to
the file cq.tif.
-p %goodlines Set the minimum percentage of ``good lines'' of data that
may appear in acceptable page of input data. A line is
good if it decodes without error to a row of pixels that
is the expected width. This is equivalent to the Per‐
centGoodLines configuration parameter; c.f. hylafax-con‐
fig(5F). By default cqtest requires that 95% of the rows
of each page be good.
EXAMPLES
The following shows a multi-page, high-resolution document with a sin‐
gle error on each page. Each page has acceptable copy quality using
the default threshold parameters.
