InkAnalyzerBase.FindInkLeafNodes Method (array<Int32[])
Returns the ink leaf nodes that contain the specified stroke data.
Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)
Syntax
'Declaration
Public Function FindInkLeafNodes ( _
strokeIds As Integer() _
) As ContextNodeBaseCollection
'Usage
Dim instance As InkAnalyzerBase
Dim strokeIds As Integer()
Dim returnValue As ContextNodeBaseCollection
returnValue = instance.FindInkLeafNodes(strokeIds)
public ContextNodeBaseCollection FindInkLeafNodes(
int[] strokeIds
)
public:
ContextNodeBaseCollection^ FindInkLeafNodes(
array<int>^ strokeIds
)
public function FindInkLeafNodes(
strokeIds : int[]
) : ContextNodeBaseCollection
Parameters
strokeIds
Type: array<System.Int32[]The identifiers for the strokes that the ink leaf nodes contain.
Return Value
Type: System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
The ink leaf nodes that contain the specified 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.
If no nodes contain the stroke data, an empty ContextNodeBaseCollection is returned. Similarly, if an empty stroke identifier array is passed in, an empty ContextNodeBaseCollection is returned.
Examples
The following example loops through all the ink leaf nodes containing the strokes specified by the 32-bit signed integer array, theStrokeIds, in the InkAnalyzerBase, theInkAnalyzerBase. It then adds the identifiers for all of the strokes in those ink leaf nodes to an expanded collection of stroke identifiers, expandedStrokeIds.
' Find the ink leaf context nodes that contain the strokes, and
' add all of the stroke identifiers for strokes in those nodes to
' a collection of stroke identifiers.
Dim expandedStrokeIds As New System.Collections.ArrayList()
Dim leafNode As System.Windows.Ink.AnalysisCore.ContextNodeBase
For Each leafNode In theInkAnalyzerBase.FindInkLeafNodes(theStrokeIds)
expandedStrokeIds.AddRange(leafNode.GetStrokeIds())
Next leafNode
// Find the ink leaf context nodes that contain the strokes, and
// add all of the stroke identifiers for strokes in those nodes to
// a collection of stroke identifiers.
System.Collections.ArrayList expandedStrokeIds =
new System.Collections.ArrayList();
foreach (System.Windows.Ink.AnalysisCore.ContextNodeBase leafNode
in theInkAnalyzerBase.FindInkLeafNodes(theStrokeIds))
{
expandedStrokeIds.AddRange(leafNode.GetStrokeIds());
