IInkStrokeContainer IInkStrokeContainer IInkStrokeContainer IInkStrokeContainer Interface

Definition

Represents a manager for the collection of InkStroke objects rendered by the InkPresenter.

Modifications made to any of the ink strokes in the stroke container are immediately rendered to the drawing surface associated with the InkPresenter.

Methods

AddStroke(InkStroke) AddStroke(InkStroke) AddStroke(InkStroke) AddStroke(InkStroke)

Adds an InkStroke object to the collection managed by the InkStrokeContainer.

public : void AddStroke(InkStroke stroke)
public void AddStroke(InkStroke stroke)
Public Function AddStroke(stroke As InkStroke) As void
iInkStrokeContainer.addStroke(stroke);
Parameters
stroke
InkStroke InkStroke InkStroke InkStroke

The ink stroke to be added.

stroke must be created by using the Clone method, or through a call to EndStroke or ProcessPointerUp. Empty or existing strokes are not valid.

Remarks

The StrokesCollected event is fired when ink strokes are processed ("wet" to "dry") on the UI thread.

See Also

public bool CanPasteFromClipboard()
Public Function CanPasteFromClipboard() As bool
var bool = iInkStrokeContainer.canPasteFromClipboard();
Returns
Platform::Boolean bool bool bool

var rect = iInkStrokeContainer.deleteSelected();
Returns

The bounding rectangle of the selected ink strokes, or the invalidated rectangle (0, 0, 0, 0) if no strokes were removed (no selected strokes).

Remarks

This method does not cause the StrokesErased event to fire.

See Also

GetRecognitionResults() GetRecognitionResults() GetRecognitionResults() GetRecognitionResults()

Gets the collection of recognition matches previously processed by an InkRecognizer and stored in an InkRecognizerContainer.

Recognition is not supported by InkStrokeContainer, you must use an InkRecognizerContainer object.

public : IVectorView<InkRecognitionResult> GetRecognitionResults()
public IReadOnlyList<InkRecognitionResult> GetRecognitionResults()
Public Function GetRecognitionResults() As IReadOnlyList<InkRecognitionResult>( Of InkRecognitionResult )
var iVectorView = iInkStrokeContainer.getRecognitionResults();
Returns
IVectorView<InkRecognitionResult> IReadOnlyList<InkRecognitionResult> IReadOnlyList<InkRecognitionResult> IReadOnlyList<InkRecognitionResult>

The results of the recognition as a collection of InkRecognitionResult objects.

See Also

GetStrokes() GetStrokes() GetStrokes() GetStrokes()

Retrieves all ink strokes in the collection managed by the InkStrokeContainer.

public : IVectorView<InkStroke> GetStrokes()
public IReadOnlyList<InkStroke> GetStrokes()
Public Function GetStrokes() As IReadOnlyList<InkStroke>( Of InkStroke )
var iVectorView = iInkStrokeContainer.getStrokes();
Returns
IVectorView<InkStroke> IReadOnlyList<InkStroke> IReadOnlyList<InkStroke> IReadOnlyList<InkStroke>

The ink strokes managed by the InkStrokeContainer as a collection of InkStroke objects.

See Also

LoadAsync(IInputStream) LoadAsync(IInputStream) LoadAsync(IInputStream) LoadAsync(IInputStream)

Asynchronously loads all InkStroke objects from the specified stream to the InkStroke collection that is managed by the InkStrokeContainer.

public : IAsyncActionWithProgress<ulong> LoadAsync(IInputStream inputStream)
public IAsyncActionWithProgress<ulong> LoadAsync(IInputStream inputStream)
Public Function LoadAsync(inputStream As IInputStream) As IAsyncActionWithProgress( Of ulong )
var iAsyncActionWithProgress = iInkStrokeContainer.loadAsync(inputStream);
Parameters
inputStream
IInputStream IInputStream IInputStream IInputStream

The stream that contains the stroke collection. An IRandomAccessStream (requires IOutputStream ) object can be specified instead.

Returns

The status of the asynchronous operation as the number of bytes fetched. For more information, see ReadAsync method.

See Also

MoveSelected(Point) MoveSelected(Point) MoveSelected(Point) MoveSelected(Point)

Moves the selected strokes. All affected strokes are re-rendered.

public : Rect MoveSelected(Point translation)
public Rect MoveSelected(Point translation)
Public Function MoveSelected(translation As Point) As Rect
var rect = iInkStrokeContainer.moveSelected(translation);
Parameters
translation
Point Point Point Point

The destination screen coordinates for the upper-left corner of the bounding rectangle of the selected strokes.

Returns

The bounding rectangle of the selected ink strokes.

Remarks

The following can result from a call to MoveSelected:

  • Moving one or more strokes that make up part of a word results in the reprocessing of existing ink recognition results.
  • Moving all strokes that make up a word results in the recalculation of the BoundingRect of the InkRecognitionResult. Ink recognition is not reprocessed.
  • Moving one or more strokes results in the recalculation of the BoundingRect for each stroke.
  • Moving one or more strokes results in the recalculation of the BoundingRect of the InkStrokeContainer.
