Hello,

Thanks for your inquiry.
Sorry we have not received any attached documents from this post.
I used the latest Spire.PDF Pack(Hot Fix) Version:8.10.5 to do an initial test, and I found that the signature picture is clear. If you are using an older version, I suggest you test again with this version. If your problem persists after the test, to help us further investigate it, please upload your file and image again, if they exceed the size limitation for attachment. You could upload them to the DropBox or OneDrive and then share the download link with us. Thank you in advance.

Sincerely,

Hello,

Thank you for sharing.
I used the following code to test your files, the signature picture of "signOut.pdf" is clear when viewing in 100% zoom mode. If you want to view in a larger zoom mode, the clarity will be changed definitely. You can zoom it in the picture viewer tool to have a test. If there is still any issues, just feel free to write back.

Code: Select all

        //Load a sample PDF file
            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile(@"sample.pdf");
            PdfCertificate cert = new PdfCertificate(@"my.pfx", "password");
            //Create a PdfSignature object and specify its position and size
            PdfSignature signature = new PdfSignature(doc, doc.Pages[0], cert, "MySignature");
            RectangleF rectangleF = new RectangleF(150, 450, 150, 100);
            signature.Bounds = rectangleF;
            signature.Certificated = true;
            //Set the graphics mode to image only
            signature.GraphicsMode = GraphicMode.SignImageOnly;
            Image image = Image.FromFile(@"Signature file.png");
            //Set the sign image source
            signature.SignImageSource = PdfImage.FromImage(image);
            signature.DocumentPermissions = PdfCertificationFlags.ForbidChanges | PdfCertificationFlags.AllowFormFill;
            //Save to file
            doc.SaveToFile(@"signOut.pdf");
            doc.Close();
