GOBLIN Graph Library 2.8b26 (Default branch)
Image The GOBLIN project consists of a C++ class library for a large series of graph optimization problems, GOSH, an extension of the Tcl/Tk scripting language to graph objects, and GOBLET, a graphical user interface to the library functions. GOBLET includes a graph editor and supports the standard graph layout methods. License: GNU Lesser General Public License (LGPL) Changes:
The Tcl API has been completely revised to conform with the method names in the C++ core library. Tcl commands now consistently support optional parameters. The HTML reference now covers all graph methods in the Tcl API. A constructor method for k-ary (cyclic) butterfly graphs has been added. Image

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

       Graph::Easy.

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.
