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).
