NAME

       genpng - Generate an overview image from a source file

SYNOPSIS

       genpng [-h|--help] [-v|--version]
              [-t|--tab-size tabsize] [-w|--width width]
              [-o|--output-filename output-filename]
              source-file

DESCRIPTION

       genpng  creates  an  overview  image  for a given source code file of either plain text or
       .gcov file format.

       Note that the GD.pm Perl module has to be installed for this script to  work  (it  may  be
       obtained from http://www.cpan.org).

       Note  also  that  genpng is called from within genhtml so that there is usually no need to
       call it directly.

OPTIONS

       -h
       --help
              Print a short help text, then exit.

       -v
       --version
              Print version number, then exit.

       -t tab-size
       --tab-size tab-size
              Use tab-size spaces in place of tab.

              All occurrences of tabulator signs in the source code file will be replaced by  the
              number of spaces defined by tab-size (default is 4).

       -w width
       --width width
              Set width of output image to width pixel.

              The resulting image will be exactly width pixel wide (default is 80).

              Note that source code lines which are longer than width will be truncated.

       -o filename
       --output-filename filename
              Write image to filename.

              Specify a name for the resulting image file (default is source-file.png).
