NAME
       cqtest - HylaFAX copy quality checking test program

SYNOPSIS
       /usr/bin/cqtest [ options ] input.tif

DESCRIPTION
       cqtest 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
       acceptable 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
                     PercentGoodLines configuration parameter; c.f.  hylafax-
                     config(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
       single error on each page.  Each page has acceptable copy quality using
       the default threshold parameters.

       hyla% /usr/bin/cqtest ~/tiff/pics/faxix.tif
