Distorted image after including image in a PDF signature

[emirdeliz]

I'm adding an image to a PDF signature. For some reason the quality of the image is lost and it becomes distorted.

I'm using .Net 6(C#) with the code below:

Code: Select all

    RectangleF rectangleF = new RectangleF(x, y, width, height);
    signature.Bounds = rectangleF;
    signature.Certificated = true;
    //Set the graphics mode
    signature.GraphicsMode = imageSignatureAsBase64 != null ? GraphicMode.SignImageAndSignDetail : GraphicMode.SignDetail;
    //Timezone Sao_Paulo UTC-3
    signature.DateLabel = $"{locationInfoLabel}, {DateTime.UtcNow.AddHours(-3).ToString("dd/MM/yyyy HH:mm:ss")}";
    signature.ContactInfoLabel = contactInfoLabel;
    signature.DistinguishedNameLabel = "Assinado digitalmente por Orizon";
    signature.ReasonLabel = $"Certificado: {cert.GetNameInfo(X509NameType.SimpleName, false)}";

    //Set the signature content
    if (imageSignatureAsBase64 != null)
    {
      MemoryStream msImageSignature = new MemoryStream(Convert.FromBase64String(imageSignatureAsBase64));
      signature.SignImageSource = PdfImage.FromStream(msImageSignature);
    }
   
    //Save to another stream file
    MemoryStream msResult = new();
    doc.SaveToStream(msResult);
    doc.Close();


Does anyone know what I can do to fix this problem?

Thanks!

Hello,

Thanks for your inquiry.
For your issue, please first check if the image itself is clear. If there is no problem with the image itself, please provide us with your image and the current input pdf file to help us further investigate. Thank you in advance.

Sincerely,
William
