Returns all of the ink leaf nodes, which are the ContextNodeBase objects that contain stroke data.

Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in iacore.dll)

Syntax

'Declaration
Public Function FindInkLeafNodes As ContextNodeBaseCollection
'Usage
Dim instance As InkAnalyzerBase
Dim returnValue As ContextNodeBaseCollection

returnValue = instance.FindInkLeafNodes

public ContextNodeBaseCollection FindInkLeafNodes ()

public:
ContextNodeBaseCollection^ FindInkLeafNodes ()

public ContextNodeBaseCollection FindInkLeafNodes ()

public function FindInkLeafNodes () : ContextNodeBaseCollection

Not applicable.

Return Value

All of the ink leaf nodes, which are the ContextNodeBase objects that contain stroke data.

Remarks

Examples of ink leaf nodes are nodes with a Type property value of InkWord, InkDrawing, and InkBullet.

Leaf nodes do not contain child nodes.

Example

The following example loops through all the ink leaf nodes of an InkAnalyzerBase, theInkAnalyzerBase, and finds the one with the lowest lower bound.

' Find the ink leaf context node that has the lowest bottom bound.
Dim lowest As Integer = Integer.MaxValue
Dim lowestNode As System.Windows.Ink.AnalysisCore.ContextNodeBase = Nothing

Dim leafNode As System.Windows.Ink.AnalysisCore.ContextNodeBase
For Each leafNode In theInkAnalyzerBase.FindInkLeafNodes()
    ' Find lowest node. Note, AnalysisRegionBase.GetBounds() returns an
    ' array containing the left, top, right, and bottom bounds in order.
    If leafNode.Location.GetBounds()(3) > lowest Then
        lowestNode = leafNode
        lowest = leafNode.Location.GetBounds()(3)
    End If
Next leafNode

// Find the ink leaf context node that has the lowest bottom bound.
int lowest = int.MaxValue;
System.Windows.Ink.AnalysisCore.ContextNodeBase lowestNode = null;
foreach (System.Windows.Ink.AnalysisCore.ContextNodeBase leafNode
    in theInkAnalyzerBase.FindInkLeafNodes())
{
    // Find lowest node. Note, AnalysisRegionBase.GetBounds() returns an
    // array containing the left, top, right, and bottom bounds in order.
    if (leafNode.Location.GetBounds()[3] > lowest)
    {
        lowestNode = leafNode;
        lowest = leafNode.Location.GetBounds()[3];
    }
}
