PHP Tree Graph Ext 0.1 (Default branch)
04-16-2008
PHP Tree Graph Ext is a PHP package that can be used to render graphical diagrams of hierarchical trees of nodes. Each node may be associated with a title, text, an image, and a desired width and height that it will occupy in the tree's graphical diagram. The colors of the image background, node, node links, and node texts are configurable. The node link style, node text font, and node border width can also be configured. The user can also choose which node will be the root, such that all nodes that aren't a descendant of the root won't be shown. License: GNU Lesser General Public License (LGPL) Changes:|

Graph::Writer::XML(3pm) User Contributed Perl Documentation Graph::Writer::XML(3pm) NAME
Graph::Writer::XML - write out directed graph as XML SYNOPSIS
use Graph; use Graph::Writer::XML; $graph = Graph->new(); # add edges and nodes to the graph $writer = Graph::Writer::XML->new(); $writer->write_graph($graph, 'mygraph.xml'); DESCRIPTION
Graph::Writer::XML is a class for writing out a directed graph in a simple XML format. The graph must be an instance of the Graph class, which is actually a set of classes developed by Jarkko Hietaniemi. The XML format is designed to support the Graph classes: it can be used to represent a single graph with a collection of nodes, and edges between those nodes. The graph, nodes, and edges can all have attributes specified, where an attribute is a (name,value) pair, with the value being scalar. METHODS
new() Constructor - generate a new writer instance. $writer = Graph::Writer::XML->new(); This doesn't take any arguments. write_graph() Write a specific graph to a named file: $writer->write_graph($graph, $file); The $file argument can either be a filename, or a filehandle for a previously opened file. KNOWN BUGS
Attribute values must be scalar. If they're not, well, you're on your own. SEE ALSO
