How to Search for QR Code Signatures Leave feedback
When you search for electronic signatures of QR-Code type inside a document with GroupDocs.Signature for Python via .NET, you only need to pass a QrCodeSearchOptions object to the search method.
Here’s a quick guide on how to search for QR-code signatures:
- Create a new instance of the Signature class and pass the source document path as a constructor parameter.
- Instantiate the QrCodeSearchOptions object according to your requirements and specify search options.
- Call the search method of the Signature class instance and pass the QrCodeSearchOptions to it.
The code snippet below demonstrates how to search for QR-code signatures in a document using Python:
import groupdocs.signature as signature
from groupdocs.signature.options import QrCodeSearchOptions
import groupdocs.signature.domain as gsd
# Initialize signature
with signature.Signature("sample.pdf") as sign:
# Search for signatures in document
signatures = sign.search(gsd.SignatureType.QR_CODE)
print("\nSource document contains the following signatures:")
for qr_code_signature in signatures:
print(f"QR Code signature found at page {qr_code_signature.page_number} "
f"with type {qr_code_signature.encode_type} and text {qr_code_signature.text}")
Here’s an example showing how to use more advanced search options for QR codes:
import groupdocs.signature as signature
from groupdocs.signature.options import QrCodeSearchOptions
from groupdocs.signature.domain import QrCodeTypes
# Initialize signature
with signature.Signature("sample.pdf") as sign:
# Create search options
search_options = QrCodeSearchOptions()
# Search on specific pages
search_options.page_number = 1
search_options.all_pages = False
# Search for specific QR code type
search_options.encode_type = QrCodeTypes.QR
# Search for specific text in QR code
search_options.text = "John"
# Search document
signatures = sign.search(search_options)
# Process found signatures
for qr_code_signature in signatures:
print(f"Found QR Code signature: {qr_code_signature.text}")
print(f"Page number: {qr_code_signature.page_number}")
print(f"Position: X={qr_code_signature.left}, Y={qr_code_signature.top}")
print(f"Size: {qr_code_signature.width}x{qr_code_signature.height}")
print(f"Encode type: {qr_code_signature.encode_type}")
print(f"Error correction level: {qr_code_signature.error_correction_level}")
