The CombinePDF sub takes two arguments as well: one for the input document and one for the output document. LogError(Nothing, "PDF Created: " + Path.GetFileName(NewPDF)) Now, add the CombinePDF sub: Private Sub CombinePDF(ExistingPDF As String, NewPDF As String)ĭim outputDocument As PdfDocument = PdfReader.Open(NewPDF)ĭim inputDocument As PdfDocument = PdfReader.Open(ExistingPDF, _ĭim count As Integer = inputDocument.PageCountĭim page As PdfPage = inputDocument.Pages(idx) The XGraphics object draws an XImage object, which hosts the image file that was supplied onto the PDF page. A Page gets added to the newly created PDF document. A PdfDocument gets created and instantiated.
