Problem exporting powerpoint slides to jpg

[Cubaman]

Hello:
I'm currently exporting a powerpoint presentation to jpg. It works
fine till there is a graph object embed in the presentation. In this
case the resulting image apears as a white empty image. The code i'm
using is as follows:

Private Shared Sub ConvertToImageInternal(ByVal params As Object)
Dim paramList As Object() = CType(params, Object())
Dim inPath As String = paramList(0)
Dim outPath As String = paramList(1)
Dim powerPointApp As Application = New Application()
Dim presentation As Presentation = Nothing
Try
presentation = powerPointApp.Presentations.Open(inPath, _

MsoTriState.msoTrue, _

MsoTriState.msoFalse, _

MsoTriState.msoFalse)
presentation.SaveAs(outPath, _
PpSaveAsFileType.ppSaveAsJPG, _
MsoTriState.msoCTrue)
presentation.Close()
powerPointApp.Quit()
Finally
GC.Collect()
GC.WaitForPendingFinalizers()
If Not presentation Is Nothing Then
Marshal.FinalReleaseComObject(presentation)
presentation = Nothing
End If
If Not powerPointApp Is Nothing Then
Marshal.FinalReleaseComObject(powerPointApp)
powerPointApp = Nothing
End If
End Try

If i export the same slides using PowerPoint app in normal way, it
just works fine. Any sugestion on how to correctly export the images?
Thanks!

Do you face the same problem if you make use of the Slide Export method,
instead of the Presentation Save As method?
