Help wanted clipping an image region and saving as new image

Help wanted clipping an image region and saving as new image....

Can someone please help me.

What I what to do is display a picture (image) and drawer a clip region using the mouse on a selected area on the image, this could be a retangle, square or a freehand shape.

I can display the image and clipped region using WPF as below. But what I cannot work out is how to save the clipped region of the image as a new bitmap image. The same problem if I create a image using pathgeometry, I cannot work out how to save the cropped part of the image.

If there is an alternative method instead of using WPF, please advice me.

Thanks

Dim myImage As Image = New Image
Dim imageUri As Uri = New Uri("C:\\Documents and Settings\\All Users\\Documents\My Pictures\\Sample Pictures\\Water lilies.jpg", UriKind.Relative)
myImage.Source = New BitmapImage(imageUri)
myImage.Width = 200
myImage.Height = 150
myImage.HorizontalAlignment = HorizontalAlignment.Left
Dim myEllipseGeometry2 As EllipseGeometry = New EllipseGeometry
myEllipseGeometry2.Center = New Point(100, 75)
myEllipseGeometry2.RadiusX = 100
myEllipseGeometry2.RadiusY = 75
myImage.Clip = myEllipseGeometry2
