Method Detail



	
	
Image_GraphViz (Constructor)   [line 121]

	

    

    

		Image_GraphViz Image_GraphViz(
[boolean
$directed = TRUE], [array
$attributes = array()], [string
$name = NULL])
    

    


	
		Constructor.
Setting the name of the Graph is useful for including multiple image maps on  one page. If not set, the graph will be named 'G'.


    

  • Access: public
    • 








        
Parameters:

    

    

          

        boolean  
        $directed  
        — 
        Directed (TRUE) or undirected (FALSE) graph.
      

          

        array  
        $attributes  
        — 
        Attributes of the graph
      

          

        string  
        $name  
        — 
        Name of the Graph

addAttributes   [line 311]

	

    

    

		void addAttributes(
array
$attributes)
    

    


	
		Add attributes to the graph.


    

  • Access: public
    • 








        
Parameters:

    

    

          

        array  
        $attributes  
        — 
        Attributes to be added to the graph.

addCluster   [line 214]

	

    

    

		void addCluster(
string
$id, array
$title, [array
$attributes = array()])
    

    


	
		Add a cluster to the graph.


    

  • Access: public
    • 








        
Parameters:

    

    

          

        string  
        $id  
        — 
        ID.
      

          

        array  
        $title  
        — 
        Title.
      

          

        array  
        $attributes  
        — 
        Attributes of the cluster.

addEdge   [line 255]

	

    

    

		void addEdge(
array
$edge, [array
$attributes = array()])
    

    


	
		Add an edge to the graph.
Caveat! This cannot handle multiple identical edges. If you use non-numeric  IDs for the nodes, this will not do (too much) harm. For numeric IDs the  array_merge() that is used will change the keys when merging arrays, leading  to new nodes appearing in the graph.


    

  • Access: public
    • 








        
Parameters:

    

    

          

        array  
        $edge  
        — 
        Start and End node of the edge.
      

          

        array  
        $attributes  
        — 
        Attributes of the edge.
