Problem adding annotation for a rotated PDF

[Hashim Saleem]

Hi,

I am facing a problem adding annotation on a PDF which has non zero rotation. The following code works fine for a PDF which has zero rotation. I have added stp.RotateContents = false; and also setting text rotation to the PDF rotation while adding text in the appearance of annotation but the output is not correct. Please guide me about what I am missing here. I am using itextsharp v4.0.8. Thanks.

                // Add annotation
                stp.AddAnnotation(pdfAnnotation, 1);
                stp.RotateContents = false;
                stp.Close();
                File.WriteAllBytes(outFile, ((MemoryStream)s).ToArray());
            }
