Search for Barcode e-Signatures Leave feedback
GroupDocs.Signature provides the ability to search for barcode signatures in documents. Barcode signatures can be used to store various types of information in a compact format.
A barcode signature is a visual representation of data that can be scanned and read by machines. It typically consists of parallel black lines and white spaces of varying widths. Barcodes are commonly used for:
- Product identification
- Inventory tracking
- Document verification
- Data encoding
The Signature class provides the Search method which allows you to search for barcode signatures in documents. Here’s how to use it:
- Create a new instance of the Signature class and pass the source document path as a parameter.
- Instantiate the BarcodeSearchOptions object with the required options.
- Call the Search method of the Signature class instance and pass the BarcodeSearchOptions to it.
- Process the search results.
Here’s an example of how to search for barcode signatures in a document:
from groupdocs.signature import Signature
from groupdocs.signature.options import BarcodeSearchOptions
from groupdocs.signature.domain import BarcodeSignature
# Initialize Signature with input document
with Signature("sample.pdf") as signature:
# Create search options
options = BarcodeSearchOptions()
# Search for signatures
result = signature.search(options)
print(f"Found {len(result)} signatures")
# Process found signatures
for barcode_signature in result:
print(f"Barcode type: {barcode_signature.barcode_type}")
print(f"Barcode text: {barcode_signature.text}")
print(f"Page number: {barcode_signature.page_number}")
print(f"Position: X={barcode_signature.left}, Y={barcode_signature.top}")
print(f"Size: Width={barcode_signature.width}, Height={barcode_signature.height}")
The BarcodeSearchOptions class provides various properties to customize the search process:
from groupdocs.signature import Signature
from groupdocs.signature.options import BarcodeSearchOptions
from groupdocs.signature.domain import BarcodeSignature
# Initialize Signature with input document
with Signature("sample.pdf") as signature:
# Create search options
options = BarcodeSearchOptions()
# Specify pages to search
options.pages = [1, 2] # Search only on pages 1 and 2
# Specify barcode types to search for
options.barcode_type = "Code128" # Search only for Code128 barcodes
# Search for signatures
result = signature.search(options)
print(f"Found {len(result)} signatures")
# Process found signatures
for barcode_signature in result:
print(f"Barcode type: {barcode_signature.barcode_type}")
print(f"Barcode text: {barcode_signature.text}")
print(f"Page number: {barcode_signature.page_number}")
print(f"Position: X={barcode_signature.left}, Y={barcode_signature.top}")
print(f"Size: Width={barcode_signature.width}, Height={barcode_signature.height}")
