Public Methods

Method	Description
Dispose ( ) : void
GenerateTree ( int width, int height, string startFromNodeId, ImageFormat imageType ) : Stream	Creates the tree
GenerateTree ( string startFromNodeId, ImageFormat imageType ) : Stream	This overloaded method can be used to return the image using it's default calculated size, without resizing
GetRectangleFromNode ( XmlNode oNode ) : Rectangle	the node holds the x,y in attributes use them to calculate the position This is public so it can be used by other classes trying to calculate the cursor/mouse location
TreeBuilder ( Tree data ) : System	ctor

Private Methods

Method	Description
BuildTree ( XmlNode oNode, int y ) : void	convert the datatable to an XML document
CalculateImageMapData ( ) : void	After resizing the image, all positions of the rectanlges need to be recalculated too.
DrawChart ( XmlNode oNode ) : void	Draws the actual chart image.
GetMaxXOfDescendants ( XmlNode currentNode ) : int	Get the maximum x of the lowest child on the current tree of nodes Recursion does not work here, so we'll use a loop to climb down the tree Recursion is not a solution because we need to return the value of the last leaf of the tree. That would require managing a global variable.
GetXPosByOwnChildren ( XmlNode currentNode ) : int
GetXPosByParentPreviousSibling ( XmlNode currentNode ) : int
GetXPosByPreviousSibling ( XmlNode currentNode ) : int
GetXmlNode ( string nodeId, string nodeDescription, string nodeNote, Color backColor, Color foreColor ) : XmlNode	create an xml node based on supplied data
OverlapExists ( ) : bool	used for testing purposes, to see if overlap exists between at least 2 boxes.
