Dear support,
We have some PDF documents with Landscape view that has some signature fields. We use Syncfusion PDF library to sign documents, but what it's happening, is that the signature value being placed in the fields is getting rotated.
I'm attaching the original document as well as the output document after signing the document. Also here is the code that I'm using to sign and fill signature fields.
//// Get the file data as binary
//var file = await _mediaFileService.GetMediaFileByIdAsync(doc.CurrentFileId);
//Load PDF document
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(file.FileData);
//Gets the first page of the document
PdfLoadedPage page = loadedDocument.Pages[0] as PdfLoadedPage;
//Gets the first signature field of the PDF document
PdfLoadedSignatureField signatureField1 = loadedDocument.Form.Fields[currentSignatory.PdfFieldRef] as PdfLoadedSignatureField;
//Creates a certificate
Stream stream = new MemoryStream(userCert.CertificateFileData);
PdfCertificate certificate1 = new PdfCertificate(stream, model.CertificatePass);
signatureField1.Signature = new PdfSignature(loadedDocument, page, certificate1, currentSignatory.PdfFieldRef, signatureField1);
signatureField1.Signature.DocumentPermissions = PdfCertificationFlags.AllowComments | PdfCertificationFlags.AllowFormFill | PdfCertificationFlags.ForbidChanges;
//Save the current graphics state
PdfGraphicsState state = signatureField1.Signature.Appearance.Normal.Graphics.Save();
PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 6);
PdfBitmap signatureImage;
if (userCert.SignatureImage != null)
{
//Draw image
RectangleF imageArea = new RectangleF(new PointF(0, 0), new SizeF(signatureField1.Signature.Bounds.Size.Width / 3, signatureField1.Signature.Bounds.Size.Height));
Stream signatureImageStream = new MemoryStream(userCert.SignatureImage);
signatureImage = new PdfBitmap(signatureImageStream);
signatureField1.Signature.Appearance.Normal.Graphics.DrawImage(signatureImage, imageArea);
}
RectangleF textArea = new RectangleF(new PointF((signatureField1.Signature.Bounds.Size.Width / 3) + 2, 0), new SizeF(signatureField1.Signature.Bounds.Size.Width / (userCert.SignatureImage != null ? 3 : 1), signatureField1.Signature.Bounds.Size.Height));
signatureField1.Signature.ContactInfo = currentSignatory.StaffName;
signatureField1.Signature.Appearance.Normal.Graphics.DrawString(String.Format("{0} on {1}", signatureField1.Signature.ContactInfo, DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss +03'00'").Replace("+0300", "+03\'00\'")), font, PdfBrushes.Black, textArea, new PdfStringFormat(PdfTextAlignment.Left, PdfVerticalAlignment.Top));
// Restore Graphics state
signatureField1.Signature.Appearance.Normal.Graphics.Restore(state);
//Save the document into stream
MemoryStream fileStream = new MemoryStream();
loadedDocument.Save(fileStream);
Appreciate your help.
Best regards,
Fady
