genpng - Generate an overview image from a source file


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


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.


Print a short help text, then exit.

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).
