Map::Tube::Plugin::Graph - Graph plugin for Map::Tube.
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.
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);
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:
$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.
