cqtest - HylaFAX copy quality checking test program
/usr/local/sbin/cqtest [ options ] input.tif
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
- -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.
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.
