Public API changes and backwards compatibility

PDF file format

Added ability to save text as a graphic path when exporting to PDF format. This allows barcode text to be rendered as vector shapes, which improves compatibility with systems that do not embed fonts.

    public function example1()
    {
        $barcodeGenerator = new BarcodeGenerator(EncodeTypes::QR, "Aspose");
        $barcodeGenerator -> getParameters() -> getImage() -> getPdf() -> setTextAsPath(true);
        $barcodeGenerator -> getParameters() -> getBarcode() -> getCodeTextParameters() -> setLocation(CodeLocation::BELOW);
        $barcodeGenerator -> getParameters() -> getBarcode() -> getCodeTextParameters() -> setColor("GREEN");
        $barcodeGenerator -> save(self::filePath . "barcode-PHP.pdf", BarCodeImageFormat::PDF);
    }

Code39 recognition quality

Recognition quality for Code39 barcodes has been enhanced, especially on low-quality or degraded images.

    public function example2(): void
    {
          $path = $this::filePath . 'code39.png';
          $reader = new BarCodeReader($path, null, DecodeType::CODE_39_FULL_ASCII);
          foreach ($reader->readBarCodes() as $result) {
              echo "CodeType: " . $result->getCodeTypeName() . PHP_EOL;
              echo "CodeText: " . $result->getCodeText("UTF-8") . PHP_EOL;
          }
    }

Default recognition types for BarCodeReader

The default recognition types for BarCodeReader have been updated from DecodeType.AllSupportedTypes to DecodeType.MostCommonTypes. This change improves performance for typical recognition scenarios by reducing the number of barcode types scanned by default.

    /** Recognize using default (MostCommonTypes) **/
    public function example3(): void
    {
        $path = $this::filePath . 'barcode.png';
        $reader = new BarCodeReader($path, null, DecodeType::CODE_128);

        foreach ($reader->readBarCodes() as $result) {
            echo "CodeType: " . $result->getCodeTypeName() . PHP_EOL;
            echo "CodeText: " . $result->getCodeText("UTF-8") . PHP_EOL;
        }
    }

    /** Explicitly use MostCommonTypes **/
    public function example4(): void
    {
        $path = $this::filePath . 'barcode-PHP.png';
        $reader = new BarCodeReader($path, null, DecodeType::MOST_COMMON_TYPES);

        foreach ($reader->readBarCodes() as $result) {
            echo "CodeType: " . $result->getCodeTypeName() . PHP_EOL;
            echo "CodeText: " . $result->getCodeText("UTF-8") . PHP_EOL;
        }
    }

    /** Fallback to AllSupportedTypes (slower scan) **/
    public function example5(): void
    {
        $path = $this::filePath . 'barcode-PHP.png';
        $reader = new BarCodeReader($path, null, DecodeType::ALL_SUPPORTED_TYPES);

        foreach ($reader->readBarCodes() as $result) {
            echo "CodeType: " . $result->getCodeTypeName() . PHP_EOL;
            echo "CodeText: " . $result->getCodeText("UTF-8") . PHP_EOL;
        }
    }

1D barcodes recognition speed

Recognition speed for most 1D barcode types has been increased when working with high-quality images. This enhancement is especially beneficial for barcode recognition from web pages or generated images, where input quality is typically high and distortion minimal.

    /** Generate a high-quality 1D barcode **/
    public function example6(): void
    {
        // 1) Generate
        $out = $this::filePath . 'barcode_code_128-PHP.png';
        $gen = new BarcodeGenerator(EncodeTypes::CODE_128, 'Aspose');
        $gen->getParameters()->getBarcode()->getXDimension()->setPixels(2);
        $gen->getParameters()->getBarcode()->getBarHeight()->setPixels(150);
        $gen->save($out, BarCodeImageFormat::PNG);

        // 2) Read with explicit set of 1D types
        $reader = new BarCodeReader(
            $out,null,
            DecodeType::CODE_11,
            DecodeType::IATA_2_OF_5,
            DecodeType::EAN_13,
            DecodeType::EAN_8,
            DecodeType::INTERLEAVED_2_OF_5,
            DecodeType::STANDARD_2_OF_5,
            DecodeType::UPCA,
            DecodeType::DATA_LOGIC_2_OF_5,
            DecodeType::DATABAR_OMNI_DIRECTIONAL,
            DecodeType::DATABAR_EXPANDED,
            DecodeType::CODE_128,
            DecodeType::CODE_93,
            DecodeType::MATRIX_2_OF_5,
            DecodeType::UPCE,
            DecodeType::DATABAR_LIMITED,
            DecodeType::CODE_39,
            DecodeType::MSI
        );

        foreach ($reader->readBarCodes() as $result) {
            echo "CodeType: " . $result->getCodeTypeName() . PHP_EOL;
            echo "CodeText: " . $result->getCodeText("UTF-8") . PHP_EOL;
        }
    }
