'Declaration

Public Function GetImageRect( _
   ByVal rectIndexThe zero based the rectangle index.
 As System.Int32, _
   ByVal scaleScale factor. Possible values: 1 - original image rect should be get; N - reduced image rect should be get.
 As System.Int32, _
   ByVal imageLoadingProgressDelegate of the image loading progress. Can be set to null (Nothing in Visual Basic).
 As Vintasoft.Imaging.Codecs.Decoders.DecodingSettings, _
   ByVal intermediateImageRequestDelegate for requesting intermediate image. Can be set to null (Nothing in Visual Basic)
 As System.EventHandler(Of ProgressEventArgs), _
   ByVal decodingSettingsThe decoding settings that should be used for decoding of page image.
 As System.EventHandler(Of IntermediateImageRequestEventArgs) _
) As Vintasoft.Imaging.VintasoftImage
