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::VCG(3pm) User Contributed Perl Documentation Graph::Writer::VCG(3pm) NAME
Graph::Writer::VCG - write out directed graph in VCG format SYNOPSIS
use Graph; use Graph::Writer::VCG; $graph = Graph->new(); # add edges and nodes to the graph $writer = Graph::Writer::VCG->new(); $writer->write_graph($graph, 'mygraph.vcg'); DESCRIPTION
Graph::Writer::VCG is a class for writing out a directed graph in the file format used by the VCG tool, originally developed for Visualising Compiler Graphs. The graph must be an instance of the Graph class, which is actually a set of classes developed by Jarkko Hietaniemi. If you have defined any attributes for the graph, nodes, or edges, they will be written out to the file, as long as they are attributes understood by VCG. METHODS
new() Constructor - generate a new writer instance. $writer = Graph::Writer::VCG->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 AND LIMITATIONS
o Attributes with non-atomic values aren't currently handled. This includes the loc, classname, colorentry, and infoname attributes for graphs, and the loc attribute for nodes, o Can currently only handle graph, node, and edge elements and their attributes. So doesn't know about foldnode_defaults and things like that. SEE ALSO
