Delete QR-Code signatures from documents Leave feedback
On this page
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.
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 to obtain list of QrCodeSignature;
- 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.
This example shows how to delete QR-Code signature that was found using Search method.
import groupdocs.signature as signature
from groupdocs.signature.options import QrCodeSearchOptions
# Initialize signature
with signature.Signature("signed.pptx") as sign:
# Create search options
options = QrCodeSearchOptions()
# Search for QR-Code signatures in the document
signatures = sign.search(options)
if len(signatures) > 0:
qr_code_signature = signatures[0]
result = sign.delete(qr_code_signature)
if result:
print(
f"QR-Code signature at location {qr_code_signature.left}x{qr_code_signature.top} "
f"and size {qr_code_signature.size} was deleted from document ['{fileName}']."
)
else:
print(
f"Signature was not deleted from the document! "
f"Signature at location {qr_code_signature.left}x{qr_code_signature.top} "
f"and size {qr_code_signature.size} was not found!"
)
