Create Cropped Thumbnail using ASPJPEG

I am using AspJpeg to create thumbnails for images. I need to preserve the aspect ratio and then crop the thumbnail image to fit in a 100 x 100 pixel area. I know how to create the thumbnail and resize it but the AspJpeg manual on cropping does not make sense to me.

To see what I need look here: http://technikcorp.com/crop.jpg

And here is my code:
==========================================================
         Set Jpeg = Server.CreateObject("Persits.Jpeg")
         ResizePath2 = vSitePath & vFolder &"\"& vMediaFile
         Jpeg.Open ResizePath2
                        Jpeg.PreserveAspectRatio = True
                        L = 100

                        If Jpeg.OriginalWidth > Jpeg.OriginalHeight Then
               Jpeg.Width = L
         Else
               Jpeg.Height = L
                        End If

                       Jpeg.Sharpen 1, 150
                       Jpeg.Quality 100
        Jpeg.Save vSitePath & vFolder &"\tn_"& vMediaFile
