Extract Stamp from PDF in C#


I want to see all stamps on a document and which StampID they have, but the GetStamps() method does always return an empty list.

		public void LogAllStampIDsTest()
			StringBuilder sb = new StringBuilder();
			var pdfContentEditor = new PdfContentEditor();



			for (int i = 1; i <= pdfContentEditor.Document.Pages.Count; i++)
				foreach (var stamp in pdfContentEditor.GetStamps(i))

			File.WriteAllText(@"C:\Stamps.txt", sb.ToString());


We use Apose.PDF (for .NET) version 22.1.0.

Am I doing something wrong here?StampedDocument.pdf (54.6 KB)
