Flatten signature is reversed

[Johnatan.Carlin]

Hi,
i have an issue with a specific pdf file that contains a digital signature, when i flat it with the following code, the signature field is flatten but also mirrored (it's reversed vertically and horizontally).
is it a bug or there are options that can avoid this behaviour ?

Code: Select all

PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile("signed.pdf");
            pdf.Form.IsFlatten = true;
            pdf.SaveToFile("signed_flatten.pdf");

I am using Spire.PDFfor.NETStandard "10.6.25" version

thanks for your help.
