  I have imported StitchEngine.dll into my .NET program and I am trying to use it with following lines: 

       Dim Stitch As New StitchEngineWrapper
       Dim opt As New OutputOptions(ExportFormat.JPEG, 100, False, True, True)
       Dim img As New List(Of String)
  
          img.Add("c:\image 1.jpg")
          img.Add("c:\image 2.jpg")
          Stitch.AddImageCacheLocations(img)
          Stitch.StartAligning()
          Stitch.StartCompositing()
          Stitch.StartCompleting()
  Dim v As System.ValueType

  v=1        

  Stitch.StartExporting("C:\export", v, 1.0, opt, False)
  

  the problem is that I can not initialize v as a crop rectangle. and I got the following error :

  An unhandled exception of type 'System.InvalidCastException' occurred in StitchEngine.dll
  Additional information: Specified cast is not valid.

  Can you please help me with this?

  Thank you,
