--------/END OF REFERENCE
I would like to thank Brent for his answers.
I agree for my error n�1, 2, 4 and 5.
The problem comes from the n�3.
# # It returned no PERL error but the dot.exe gives a long
# # unreadable strange characters string
# # in the black dos window.
# This is the third error. It's also the one that's causing your trouble.
# The output from that Perl script is a PNG file--it shouldn't be run
# through dot.
Here again I agree. The dot.exe shouldn't been called.
But it's not the case : if you read the CPAN GraphViz.pm code
(at line 987)
my $program = $self->{DIRECTED} ? 'dot' : 'neato';
run [$program, $type], \$dot, ">", binary(), $out;
return $buffer unless defined $output;
It tries to run DOT.EXE (from which the output is awfull).
My own code doesn't call the binary but the .PM does.
Perhaps is there something I misunderstand with this package...
Can anybody help me ?
Christophe
