NAME

Graph::Easy::Layout::Grid - Grid management and size calculation

SYNOPSIS

         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 |
         # +------+     +--------+
 
 

DESCRIPTION

"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.

EXPORT

Exports nothing.

SEE ALSO

METHODS

This module injects the following methods into Graph::Easy:

_prepare_layout()

         my ($rows,$cols,$max_x,$max_y, \@V) = $graph->_prepare_layout();
 
 

Returns two hashes ($rows and $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.
