StrokeCollection.Erase Method (IEnumerable<Point>)

Removes the ink that is within the bounds of the specified area.

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

public void Erase(
	IEnumerable<Point> lassoPoints
)

Parameters

lassoPoints
Type: System.Collections.Generic.IEnumerable<Point>

An array of type Point that specifies the area to be erased.

The Erase method connects the first and last points in lassoPoints to create the lasso.

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.

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

The following example demonstrates how to erase strokes in a StrokeCollection. This example assumes that there is an InkPresenter called presenter.

// Erase the selected strokes. 
public void EraseStrokes(Stroke lasso)
{
    Point[] strokePoints = (Point[])lasso.StylusPoints;
    presenter.Strokes.Erase(strokePoints);
}
