Update Barcode Signatures in Document Leave feedback

GroupDocs.Signature for Python via .NET provides functionality to manipulate barcode signatures’ location, size, and textual content. Please note that the update method modifies the same document that was passed to the constructor of the Signature class.

• Create a new instance of the Signature class and pass the source document path as a constructor parameter
• Instantiate the BarcodeSearchOptions object with desired properties
• Call the search method to obtain a list of barcode signatures
• Select from the list the BarcodeSignature object(s) that should be updated
• Call the Signature object’s update method and pass one or several signatures to it

This example shows how to update a Barcode signature that was found using the search method:

import groupdocs.signature as signature
from groupdocs.signature.options import BarcodeSearchOptions

# Initialize signature
with signature.Signature("sample_signed.pdf") as sign:
    # Create search options
    options = BarcodeSearchOptions()
    
    # Search for barcode signatures in document
    signatures = sign.search(options)
    
    if len(signatures) > 0:
        # Get first barcode signature
        barcode_signature = signatures[0]
        
        # Change position
        barcode_signature.left = 100
        barcode_signature.top = 100
        
        # Update the signature
        result = sign.update(barcode_signature)
        
        if result.updated_count > 0:
            print(f"Signature with barcode '{barcode_signature.text}' was updated!")
        else:
            print("Signature was not updated in the document!")
