NAME

Map::Tube::Plugin::Graph - Graph plugin for Map::Tube.

VERSION

Version 0.31

DESCRIPTION

It's a graph plugin for Map::Tube to create map of individual lines defined as Moo Role. Once installed, it gets plugged into Map::Tube::* family.

SYNOPSIS

    use strict; use warnings;
    use MIME::Base64;
    use Map::Tube::London;

    my $tube = Map::Tube::London->new;

    # Entire map image
    my $name = $tube->name;
    open(my $MAP_IMAGE, ">", "$name.png")
        or die "ERROR: Can't open [$name.png]: $!";
    binmode($MAP_IMAGE);
    print $MAP_IMAGE decode_base64($tube->as_image);
    close($MAP_IMAGE);

    # Just a particular line map image
    my $line = 'Bakerloo';
    open(my $LINE_IMAGE, ">", "$line.png")
        or die "ERROR: Can't open [$line.png]: $!";
    binmode($LINE_IMAGE);
    print $LINE_IMAGE decode_base64($tube->as_image($line));
    close($LINE_IMAGE);

INSTALLATION

The plugin primarily depends on GraphViz2 library. But the GraphViz2 can only be installed if the perl v5.014002 or above is installed. If your perl environment satisfies this requirement then ignore the rest of instructions.

Having said that I still managed to install GraphViz2 on my box with perl 5.10.1. It requires a bit of nasty hack. If you are willing to do then follow the steps below:

  • Download the tar ball from CPAN. e.g. wget http://search.cpan.org/CPAN/authors/id/R/RS/RSAVAGE/GraphViz2-2.34.tgz

  • Extract the tar ball i.e. tar -xvzf GraphViz2-2.34.tgz

  • Change directory to GraphViz2-2.34 i.e. cd GraphViz2-2.34

  • Edit the Makefile.PL and comment the line (no: 11) that says: require 5.014002; # For the utf8 stuff.

  • Now follow the usual command to make/test/install. If it complains about missing package then install it on demand one at a time.

METHODS

as_image($line_name)

The $line_name param is optional.If it's passed, the method returns the base64 encoded string of the given line map. Otherwise you would get the entire map as base64 encoded string.

See SYNOPSIS for more details on how it can be used.
