Delete QR-Code signatures from documents Leave feedback

GroupDocs.Signature provides QrCodeSignature class to manipulate QR-Code signatures and delete them from the documents over delete method.
Please be aware that delete method modifies the same document that was passed to constructor of Signature class, so the example below copies the signed document first and deletes the signature from the copy.

Here are the steps to delete QR-Code signature from the document with GroupDocs.Signature:

• Create new instance of Signature class and pass source document path as a constructor parameter;
• Instantiate QrCodeSearchOptions object with desired properties;
• Call search method; the signatures property of the returned SearchResult holds the found QrCodeSignature objects;
• Select from list QrCodeSignature object(s) that should be removed from the document;
• Call Signature object delete method and pass one or several signatures to it; for a single signature it returns True when the signature was deleted.

This example shows how to delete QR-Code signature that was found using search method.

import shutil

from groupdocs.signature import Signature
from groupdocs.signature.options import QrCodeSearchOptions


def delete_qr_code_signature():
    # delete() saves the changes into the opened document, so work on a copy
    shutil.copy("signed.pptx", "qr_code_signature_deleted.pptx")

    with Signature("qr_code_signature_deleted.pptx") as signature:
        signatures = signature.search([QrCodeSearchOptions()]).signatures
        print(f"Found {len(signatures)} QR-Code signature(s)")
        if not signatures:
            return

        qr_code_signature = signatures[0]
        if signature.delete(qr_code_signature):
            print(f"Deleted QR-Code '{qr_code_signature.text}' ({qr_code_signature.encode_type.type_name}) "
                  f"at ({qr_code_signature.left}, {qr_code_signature.top})")
        else:
            print(f"QR-Code '{qr_code_signature.text}' was not deleted")


if __name__ == "__main__":
    delete_qr_code_signature()
