Delete blank pages from a pdf file

[Ambrogio Brambilla]

How can I delete blank pages from an existing pdf file?

Hi Ambrogio,

Thank you for using Syncfusion products.

At present, removing a blank page is possible in the PDF document contains images and text only. If the document contains shapes such as rectangle circle etc,. removing the blank page will not be possible. Please find the sample to remove the blank page when the page does not contain any images and text. However, we have logged this as a feature request in our database. We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. We will update you when this feature has been implemented.

I am sorry. Bue we use VB. Could you please provide us with the VB code?
Thanks

Moreover, I succeeded in translating to VB.
The only problem I have is the size of the new pdf file (bigger than the original one!)
I tried to manage it if the compression but it doesn't work.
Here is my code:

Dim pdfDoc1 As PdfLoadedDocument = New PdfLoadedDocument(Oggetto)

Dim i As Integer
Dim img As Image()
Dim text As String
Dim pagenum As Integer = (pdfDoc1.Pages.Count - 1)

For i = 0 To pagenum
If i > (pdfDoc1.Pages.Count - 1) Then
Exit For
End If
img = pdfDoc1.Pages(i).ExtractImages()
text = pdfDoc1.Pages(i).ExtractText()
If (text Is DBNull.Value) Then
text = ""
End If
If img.Length = 0 And Len(text) = 0 Then

pdfDoc1.Pages.RemoveAt(i)

End If
Next i
pdfDoc1.Compression = PdfCompressionLevel.Best

pdfDoc1.Save(OggettoSave)
pdfDoc1.Close(True)
pdfDoc1 = Nothing
