ContextNodeCollection Class
Contains a collection of ContextNode objects that are the result of an ink analysis.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)
Syntax
'Declaration
Public Class ContextNodeCollection _
Implements ICollection, IEnumerable
'Usage
Dim instance As ContextNodeCollection
public class ContextNodeCollection : ICollection,
IEnumerable
public ref class ContextNodeCollection : ICollection,
IEnumerable
public class ContextNodeCollection implements ICollection, IEnumerable
Examples
The following example shows how to loop through a ContextNodeCollection from the InkAnalyzer. FindNodesOfType(ContextNodeType, ContextNode) method of an InkAnalyzer, theInkAnalyzer. The example loops through all of the line nodes and, if two ink word nodes are present with the same word, then it marks them as red.
' If two identical ink words occur next to each other, mark them as red.
' Note: This doesn't actually look for pairs that go across two lines.
Dim lines As ContextNodeCollection = _
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line)
Dim lineNode As ContextNode
Dim stroke As Stroke
For Each lineNode In lines
Dim previousWord As InkWordNode = Nothing
Dim inkWord As InkWordNode
For Each inkWord In _
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, lineNode)
If Not (previousWord Is Nothing) AndAlso _
previousWord.GetRecognizedString() = inkWord.GetRecognizedString() Then
For Each stroke In previousWord.Strokes
stroke.DrawingAttributes = New DrawingAttributes(Color.Red)
Next stroke
For Each stroke In inkWord.Strokes
stroke.DrawingAttributes = New DrawingAttributes(Color.Red)
Next stroke
End If
previousWord = inkWord
Next inkWord
Next lineNode
// If two identical ink words occur next to each other, mark them as red.
// Note: This doesn't actually look for pairs that go across two lines.
ContextNodeCollection lines =
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
InkWordNode previousWord = null;
foreach (InkWordNode inkWord in
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, lineNode))
{
if (previousWord != null &&
previousWord.GetRecognizedString() == inkWord.GetRecognizedString())
{
foreach (Stroke stroke in previousWord.Strokes)
stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
foreach (Stroke stroke in inkWord.Strokes)
stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
}
previousWord = inkWord;
