eSign document with multiple signatures Leave feedback
GroupDocs.Signature allows signing a document with several signatures simultaneously and even apply signatures of different types to the same document.
Doing this is as simple as:
- Create a new instance of the Signature class and pass the source document path or stream as a constructor parameter.
- Instantiate all required sign options objects depending on signature type:
- BarcodeSignOptions - for Barcode signatures;
- DigitalSignOptions - for Digital signatures;
- FormFieldSignOptions - for Form-field signatures;
- ImageSignOptions - for Image signatures;
- MetadataSignOptions - for Metadata signatures;
- QrCodeSignOptions - for QR-code signatures
- StampSIgnOptions - for Stamp signatures;
- TextSignOptions - for Text signatures.
- Fill the collection with sign options from the previous step.
- Call the Sign method of the Signature class instance and pass the collection of sign options to it.
This code snippet below demonstrates how to eSign a PDF document with multiple signatures at the same time.
using (Signature signature = new Signature("sample.pdf"))
{
// define several signature options of different types and settings
TextSignOptions textOptions = new TextSignOptions("This is test message")
{
VerticalAlignment = VerticalAlignment.Top,
HorizontalAlignment = HorizontalAlignment.Left
};
BarcodeSignOptions barcodeOptions = new BarcodeSignOptions("123456")
{
EncodeType = BarcodeTypes.Code128,
Left = 100,
Top = 100
};
QrCodeSignOptions qrcodeOptions = new QrCodeSignOptions("JohnSmith")
{
EncodeType = QrCodeTypes.QR,
Left = 100,
Top = 200
};
DigitalSignOptions digitalOptions = new DigitalSignOptions("certificate.pfx")
{
ImageFilePath = Constants.ImageHandwrite,
VerticalAlignment = VerticalAlignment.Center,
HorizontalAlignment = HorizontalAlignment.Center,
Password = "1234567890"
};
// define list of signature options
List<SignOptions> listOptions = new List<SignOptions>();
listOptions.Add(textOptions);
listOptions.Add(barcodeOptions);
listOptions.Add(qrcodeOptions);
listOptions.Add(digitalOptions);
// sign document to file
signature.Sign("signed.pdf", listOptions);
}
