PDF Form to Image problem

Aspose.PDF Product Family
1

Hi,
I have a PDF form which of I need a preview. When I use this code (from examples):
’ The path to the documents directory.
Dim dataDir As String = Path.GetFullPath("…/…/…/Data/")
'create PdfConverter object
Dim objConverter As New PdfConverter()

'bind input pdf file
objConverter.BindPdf(dataDir & “input.pdf”)

'initialize the converting process
objConverter.DoConvert()
objConverter.ShowHiddenAreas = True

'check if pages exist and then convert to image one by one
Do While objConverter.HasNextImage()
objConverter.GetNextImage(dataDir & DateTime.Now.Ticks.ToString() & “.jpg”, System.Drawing.Imaging.ImageFormat.Jpeg)
Loop

'close the PdfConverter object
objConverter.Close()

I get Object refernce not set to an instance of an object exception on BindPdf function.
When I use this code:
Public Class RenderPdf
Implements IRenderer

Private Pdf As Aspose.Pdf.Document

Public Sub New(FilePath As String)
Pdf = New Aspose.Pdf.Document(FilePath)
End Sub

<MethodImpl(MethodImplOptions.Synchronized)>
Public Function RenderFull(Page As Integer) As Byte() Implements IRenderer.RenderFull
Using imageStream As New MemoryStream()
Dim resolution As New Aspose.Pdf.Devices.Resolution(300)
If Pdf.Pages(Page).Rect.Width >= 2000 Or Pdf.Pages(Page).Rect.Height >= 2000 Then resolution = New Aspose.Pdf.Devices.Resolution(60)
Dim jpegDevice As New Aspose.Pdf.Devices.JpegDevice(resolution)
jpegDevice.Process(Pdf.Pages(Page), imageStream)
RenderFull = imageStream.ToArray()
imageStream.Close()
End Using
End Function

Public Sub Close() Implements IRenderer.Close
Pdf.Dispose()
End Sub

Public Function PageCount() As Integer Implements IRenderer.PageCount
Return Pdf.Pages.Count
End Function
End Class

I get one image saying Please wait… and someother text.
Pdf and image in attachments.

Thanks Pilscom.
