InkAnalyzer.AddStroke Method (Stroke)
Adds a Stroke to the InkAnalyzer and assigns the active input thread's locale identifier to the stroke.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)
'Declaration
Public Function AddStroke ( _
strokeToAdd As Stroke _
) As ContextNode
'Usage
Dim instance As InkAnalyzer
Dim strokeToAdd As Stroke
Dim returnValue As ContextNode
returnValue = instance.AddStroke(strokeToAdd)
public ContextNode AddStroke(
Stroke strokeToAdd
)
public:
ContextNode^ AddStroke(
Stroke^ strokeToAdd
)
public function AddStroke(
strokeToAdd : Stroke
) : ContextNode
strokeToAdd
Type: Microsoft.Ink.StrokeThe Stroke to add to the InkAnalyzer.
Type: Microsoft.Ink.ContextNode
The ContextNode to which strokeToAdd was added.
The InkAnalyzer adds the Stroke to an UnclassifiedInkNode in the RootNode property's SubNodes collection. The Stroke, strokeToAdd, is assigned the locale identifier of the active input thread and is added to the first UnclassifiedInkNode containing strokes with the same locale identifier. If no such UnclassifiedInkNode exists, a new UnclassifiedInkNode is created and strokeToAdd is added to the new UnclassifiedInkNode.
This method expands the DirtyRegion to the union of the region's current value and the bounding box of the added stroke.
If the stroke is already attached to the InkAnalyzer, the InkAnalyzer throws an exception.
This example does the following.
Initializes a new Microsoft.Ink.InkCollector object, theInkCollector.
Attaches a InkCollector.Stroke event handler, theInkCollector_Stroke, to theInkCollector.
Initializes a new InkAnalyzer, theInkAnalyzer, that can analyze stroke data from the InkCollector object's Ink.
' Create and enable the InkCollector and attach event handlers.
Me.theInkCollector = New Microsoft.Ink.InkCollector(Me.theInkingPanel)
AddHandler Me.theInkCollector.Stroke, AddressOf Me.theInkCollector_Stroke
Me.theInkCollector.Enabled = True
' Create the InkAnalyzer.
Me.theInkAnalyzer = New Microsoft.Ink.InkAnalyzer(Me.theInkCollector.Ink, Me)
// Create and enable the InkCollector and attach event handlers.
this.theInkCollector =
new Microsoft.Ink.InkCollector(this.theInkingPanel);
this.theInkCollector.Stroke +=
new Microsoft.Ink.InkCollectorStrokeEventHandler(
this.theInkCollector_Stroke);
this.theInkCollector.Enabled = true;
// Create the InkAnalyzer.
this.theInkAnalyzer =
new Microsoft.Ink.InkAnalyzer(this.theInkCollector.Ink, this);
In this example, the theInkCollector_Stroke event handler then takes the stroke that has been added to the theInkCollector and adds it to theInkAnalyzer.
