Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in microsoft.ink.dll)

Syntax

'Declaration
Public Function ExtractStrokes ( _
    extractionRectangle As Rectangle, _
    extractionFlags As ExtractFlags _
) As Ink
'Usage
Dim instance As Ink
Dim extractionRectangle As Rectangle
Dim extractionFlags As ExtractFlags
Dim returnValue As Ink

returnValue = instance.ExtractStrokes(extractionRectangle, extractionFlags)

public Ink ExtractStrokes (
    Rectangle extractionRectangle,
    ExtractFlags extractionFlags
)

public:
Ink^ ExtractStrokes (
    Rectangle extractionRectangle, 
    ExtractFlags extractionFlags
)

public Ink ExtractStrokes (
    Rectangle extractionRectangle, 
    ExtractFlags extractionFlags
)

public function ExtractStrokes (
    extractionRectangle : Rectangle, 
    extractionFlags : ExtractFlags
) : Ink

Not applicable.

Parameters

extractionRectangle
The Rectangle that delimits the ink to extract from the Ink object.

extractionFlags
One of the ExtractFlags values that specifies whether the ink is cut or copied into the new Ink object.

Return Value

Returns an Ink object that contains the extracted Strokes collection.

Remarks

The new Ink object retains the drawing attributes, properties, and coordinates of the original Ink object.

The default behavior for this method is to remove the Strokes collection from the original Ink object. To preserve the Strokes collection in the original Ink object and make a copy of the Ink, call either the ExtractStrokes or ExtractStrokes overload of this method with the extractionFlags parameter set to the CopyFromOriginal value from the ExtractFlags enumeration.

Example

This C# example creates a new Ink object, theNewInk. The new Ink object contains a copy of the Strokes collection from the Ink object that is in an InkCollector object, theInkCollector, and that is bounded by the Rectangle, rectSelection. The Strokes collection is preserved in the original Ink object, because the extractionFlags parameter is set to the CopyFromOriginal value from the ExtractFlags enumeration.

Ink theNewInk = theInkCollector.Ink.ExtractStrokes(rectSelection,
    ExtractFlags.CopyFromOriginal);

This Microsoft Visual Basic.NET example creates a new Ink object, theNewInk. The new Ink object contains a copy of the Strokes collection from the Ink object that is in an InkCollector object, theInkCollector, and that is bounded by the Rectangle, rectSelection. The Strokes collection is preserved in the original Ink object, because the extractionFlags parameter is set to the CopyFromOriginal value from the ExtractFlags enumeration.

Dim theNewInk As Ink = theInkCollector.Ink.ExtractStrokes(rectSelection, _
    ExtractFlags.CopyFromOriginal)
