// Title: Code11 barcode generation and checksum‑disabled batch reading
// Description: Demonstrates generating Code11 barcodes, saving them as PNG, and reading them back with checksum validation turned off.
// Prompt: Set BarcodeSettings.ChecksumValidation to Off to disable checksum verification for Code 11 during batch processing.
