CQTEST(8C)																CQTEST(8C)

NAME

       cqtest - HylaFAX copy quality checking test program

SYNOPSIS

       /usr/sbin/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  scan-
       lines 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  con-
		     secutive 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	configura-
		     tion 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/sbin/cqtest ~/tiff/pics/faxix.tif
       1728 x 297, 7.7 line/mm, 1-D MH, lsb-to-msb
       RECV/CQ: Bad 1D pixel count, row 245, got 1616, expected 1728
       RECV: 2234 total lines, 1 bad lines, 1 consecutive bad lines
       1728 x 297, 7.7 line/mm, 1-D MH, lsb-to-msb
       RECV/CQ: Bad 1D pixel count, row 148, got 3023, expected 1728
       RECV: 2234 total lines, 1 bad lines, 1 consecutive bad lines
       1728 x 297, 7.7 line/mm, 1-D MH, lsb-to-msb
       RECV/CQ: Bad 1D pixel count, row 151, got 1722, expected 1728
       RECV: 2234 total lines, 1 bad lines, 1 consecutive bad lines
       1728 x 297, 7.7 line/mm, 1-D MH, lsb-to-msb
       RECV/CQ: Bad 1D pixel count, row 148, got 1776, expected 1728
       RECV: 2234 total lines, 1 bad lines, 1 consecutive bad lines
