Public API changes and New Features

OnlyRequestedTypes property for strict barcode type filtering

Methods setOnlyRequestedTypes(bool $value) and isOnlyRequestedTypes() have been added to the Aspose\Barcode\Recognition\BarcodeSettings class.

When enabled, Aspose\Barcode\Recognition\BarCodeReader returns only the barcode types explicitly specified in the decoding settings. Compatible or equivalent barcode types are excluded from the results, even if they can be successfully recognized.

When disabled, compatible and equivalent barcode types may be returned according to internal type mapping. For example, EAN-13 may also be returned when UPC-A is specified as the decoding type.

public function test()
{
    $file_name = "test.png";
    // generate barcode
    $generator = new BarcodeGenerator(EncodeTypes::EAN_13, "2383823482894");
    $generator->save(self::FOLDER . $file_name, BarCodeImageFormat::PNG);

    // recognize only UPCA barcodes (no results, because source is EAN13)
    $reader1 = new BarCodeReader(self::FOLDER . $file_name, null, DecodeType::UPCA);
    $reader1->getBarcodeSettings()->setOnlyRequestedTypes(true);

    $results1 = $reader1->readBarCodes();

    if (count($results1) === 0) {
        echo "No barcodes found (OnlyRequestedTypes = true)\n";
    }

    foreach ($results1 as $result) {
        echo "BarCode CodeText: " . $result->getCodeText() . "\n";
    }

    // recognize compatible types: EAN13, UPCA, ISSN, ISMN, ISBN (EAN13 will be returned as UPCA-equivalent)
    $reader2 = new BarCodeReader(self::FOLDER . $file_name, null, DecodeType::UPCA);
    $reader2->getBarcodeSettings()->setOnlyRequestedTypes(false);

    $results2 = $reader2->readBarCodes();

    if (count($results2) === 0) {
        echo "No barcodes found (OnlyRequestedTypes = false)\n";
    }

    foreach ($results2 as $result) {
        echo "BarCode CodeText: " . $result->getCodeText() . "\n";
    }
}
