'Declaration

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

imageLoadingProgress: Delegate of the image loading progress. Can be set to null (Nothing in Visual Basic).
intermediateImageRequest: Delegate for requesting intermediate image. Can be set to null (Nothing in Visual Basic)

Return Value

Scaled rectangle of image.
