Hello,
I sent you a sample file for which the buffer position of the stamp is not respected.

Best regards

Hello,

Thank you for sharing the sample file.
After analyzing, I found that your file is rotated 270 degrees, when you add the stamp, you need to rotate the page back firstly. Thus, please refer to the following sample code to add a stamp on the top left. If there is any other question, just feel free to contact us.

Code: Select all

 //load original pdf
 PdfDocument doc = new PdfDocument();
 doc.LoadFromFile(@"Test.pdf");
 //create a new pdf
 PdfDocument newPdf = new PdfDocument();
 //load the image to fill stamp
 PdfImage image = PdfImage.FromFile(@"logo.png");
 foreach (PdfPageBase page in doc.Pages)
 {
     PdfPageBase newPage;
     //judge if the page rotated and rotate it back
     if (page.Rotation == PdfPageRotateAngle.RotateAngle90)
         newPage = newPdf.Pages.Add(new SizeF(page.Size.Height, page.Size.Width), new PdfMargins(0));
     else if (page.Rotation == PdfPageRotateAngle.RotateAngle270)
         newPage = newPdf.Pages.Add(new SizeF(page.Size.Height, page.Size.Width), new PdfMargins(0));
     else
         newPage = newPdf.Pages.Add(page.Size, new PdfMargins(0));
     page.CreateTemplate().Draw(newPage, new PointF(0, 0));
     //add an image stamp on the top left
     PdfRubberStampAnnotation loStamp = new PdfRubberStampAnnotation(new RectangleF(new PointF(10, 10), new SizeF(20, 20)));
     PdfAppearance loApprearance = new PdfAppearance(loStamp);
     PdfTemplate template = new PdfTemplate(30, 30);
     template.Graphics.DrawImage(image, 0, 0);
     loApprearance.Normal = template;
     loStamp.Appearance = loApprearance;
     newPage.AnnotationsWidget.Add(loStamp);
 }
 newPdf.SaveToFile(@"result.pdf", Spire.Pdf.FileFormat.PDF);
