StrokeCollection.Erase Method (Rect)

 

Replaces all strokes that are clipped by the specified rectangle with new strokes that do not enter the bounds of the specified rectangle.

Namespace:   System.Windows.Ink
Assembly:  PresentationCore (in PresentationCore.dll)

public void Erase(
	Rect bounds
)

Parameters

bounds
Type: System.Windows.Rect

A Rect that specifies the area to be erased.

The StrokeCollection might contain new strokes after the Erase method is called. For example, if the specified area is through the middle of a Stroke, the erase method removes that Stroke and creates two new strokes. All strokes that are entirely inside the specified rectangle are removed.

The Erase method raises the StrokesChanged event for each Stroke it erases.

The following example demonstrates how to erase the ink within the Rect. This example assumes that there is an InkPresenter called presenter.

Rect rect = new Rect(100, 100, 200, 200);
presenter.Strokes.Erase(rect);
