Graph::Easy::Layout::Grid - Grid management and size calculation
use Graph::Easy; my $graph = Graph::Easy->new(); my $bonn = Graph::Easy::Node->new( name => 'Bonn', ); my $berlin = Graph::Easy::Node->new( name => 'Berlin', ); $graph->add_edge ($bonn, $berlin); $graph->layout(); print $graph->as_ascii( ); # prints: # +------+ +--------+ # | Bonn | --> | Berlin | # +------+ +--------+
Graph::Easy::Layout::Grid contains routines that calculate cell sizes on the grid, which is necessary for ASCII, boxart and SVG output.
Used automatically by Graph::Easy.
This module injects the following methods into Graph::Easy:
my ($rows,$cols,$max_x,$max_y, \@V) = $graph->_prepare_layout();
Returns two hashes (
$cols), containing the columns and rows of the layout with their nec. sizes (in chars) plus the maximum framebuffer size nec. for this layout. Also returns reference of a list of all cells to be rendered.
