## Overview

This is a small PHP barcode-generation library. Applications select a barcode type and output options through the service, which delegates encoding and rendering to the bundled legacy generator and returns a result object for retrieval, encoding, or file saving. The README documents broad QR, Data Matrix, and 1D symbology support; the sampled legacy source is incomplete, so those capabilities are represented together rather than as unsupported per-encoder components.

Main entry points: [`src/BarcodeService.php`](https://github.com/emirustaoglu/barcode/blob/main/src/BarcodeService.php) (Barcode Service), [`src/BarcodeResult.php`](https://github.com/emirustaoglu/barcode/blob/main/src/BarcodeResult.php) (Barcode Result), [`src/Barcode.php`](https://github.com/emirustaoglu/barcode/blob/main/src/Barcode.php) (Barcode Facade), [`src/BarcodeType.php`](https://github.com/emirustaoglu/barcode/blob/main/src/BarcodeType.php) (Barcode Types)
