eSign Document with Multiple Signatures Leave feedback
On this page
GroupDocs.Signature for Python via .NET 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 Python:
import groupdocs.signature as signature
from groupdocs.signature.options import TextSignOptions, BarcodeSignOptions, QrCodeSignOptions, DigitalSignOptions
from groupdocs.signature.domain import BarcodeTypes, QrCodeTypes
import groupdocs.signature.domain as gsd
import sys
import os
def run():
with signature.Signature("./sample.pdf") as sign:
# Define text signature options
text_options = TextSignOptions("This is test message")
text_options.vertical_alignment = gsd.VerticalAlignment.TOP
text_options.horizontal_alignment = gsd.HorizontalAlignment.LEFT
# Define barcode signature options
barcode_options = BarcodeSignOptions("123456")
barcode_options.encode_type = BarcodeTypes.CODE_128
barcode_options.left = 100
barcode_options.top = 100
# Define QR code signature options
qrcode_options = QrCodeSignOptions("JohnSmith")
qrcode_options.encode_type = QrCodeTypes.QR
qrcode_options.left = 100
qrcode_options.top = 200
# Define digital signature options
digital_options = DigitalSignOptions("./certificate.pfx")
digital_options.image_file_path = "./signature.jpg"
digital_options.vertical_alignment = gsd.VerticalAlignment.CENTER
digital_options.horizontal_alignment = gsd.HorizontalAlignment.CENTER
digital_options.password = "1234567890"
# Define list of signature options
list_options = [text_options, barcode_options, qrcode_options, digital_options]
# Sign document
sign.sign("./signed.pdf", list_options)
Here’s a more advanced example showing how to add multiple signatures with different styles and positions:
import groupdocs.signature as signature
from groupdocs.signature.options import TextSignOptions, ImageSignOptions, QrCodeSignOptions
from groupdocs.signature.domain import QrCodeTypes
import groupdocs.signature.domain as gsd
import sys
import os
def run():
with signature.Signature("./sample.pdf") as sign:
# Create text signature options
text_options = TextSignOptions("Approved by John Smith")
text_options.font = gsd.SignatureFont()
text_options.font.bold = True
text_options.font.size = 20.0
text_options.font.family_name = "Arial"
text_options.vertical_alignment = gsd.VerticalAlignment.TOP
text_options.horizontal_alignment = gsd.HorizontalAlignment.RIGHT
text_options.margin = gsd.Padding(10, 10, 0, 0)
# Create image signature options
image_options = ImageSignOptions("./stamp.png")
image_options.width = 200
image_options.height = 100
image_options.vertical_alignment = gsd.VerticalAlignment.BOTTOM
image_options.horizontal_alignment = gsd.HorizontalAlignment.LEFT
image_options.margin = gsd.Padding(0, 0, 10, 10)
# Create QR code signature options
qrcode_options = QrCodeSignOptions("https://www.example.com/verify")
qrcode_options.encode_type = QrCodeTypes.QR
qrcode_options.width = 100
qrcode_options.height = 100
qrcode_options.vertical_alignment = gsd.VerticalAlignment.CENTER
qrcode_options.horizontal_alignment = gsd.HorizontalAlignment.CENTER
# Define list of signature options
list_options = [text_options, image_options, qrcode_options]
# Sign document
sign.sign("./signed.pdf", list_options)
### Summary
This guide demonstrates how to apply multiple types of electronic signatures (e.g., text, barcode, image) to a document using [**GroupDocs.Signature for Python via .NET**](https://products.groupdocs.com/signature/python-net). It explains how to combine different signature types, configure each one, and save the signed document with multiple signature styles.
