Remarks

The PdfDocumentFacade.Pages property returns a list of objects used to organize the PDF page without access to its inner structure. Call the PdfPageFacade.FlattenAnnotations() method to flatten the page annotations.

The code sample below flattens all annotations that are located on the lower half of the page:

C#

using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
  // Load a document:
  processor.LoadDocument("..\\..\\Document.pdf");

  // Flatten annotations located
  // on the lower half of the page:
  PdfPageFacade pageFacade = documentFacade.Pages[0];

  double halfPage = processor.Document.Pages[0].CropBox.Top / 2;
  pageFacade.FlattenAnnotations(x => x.Rectangle.Top < halfPage);

  // Save the result:
  processor.SaveDocument("..\\..\\Result.pdf");
}

VB.NET

Using processor As New PdfDocumentProcessor()
  ' Load a document:
  processor.LoadDocument("..\..\Document.pdf")

  ' Flatten annotations located
  ' on the lower half of the page:
  Dim pageFacade As PdfPageFacade = documentFacade.Pages(0)

  Dim halfPage As Double = processor.Document.Pages(0).CropBox.Top / 2
  pageFacade.FlattenAnnotations(Function(x) x.Rectangle.Top < halfPage)

  ' Save the result:
  processor.SaveDocument("..\..\Result.pdf")
End Using

You can also flatten a specific annotation. Use the PdfPageFacade.Annotations property to retrieve a list of annotation facade objects and utilize the PdfAnnotationFacade.Flatten() method.
