ChecksumValidation

Enable checksum validation during recognition for 1D and Postal barcodes.

Default is treated as Yes for symbologies which must contain checksum, as No where checksum only possible.

Checksum never used: Codabar, PatchCode, Pharmacode, DataLogic2of5

Checksum is possible: Code39 Standard/Extended, Standard2of5, Interleaved2of5, ItalianPost25, Matrix2of5, MSI, ItalianPost25, DeutschePostIdentcode, DeutschePostLeitcode, VIN

Checksum always used: Rest symbologies

[XmlSerialization(Type = XmlSerializationType.Element)]
public ChecksumValidation ChecksumValidation { get; set; }

Returns

ChecksumValidation

Returns

Tämä esimerkki osoittaa ChecksumValidationin vaikutuksen havaitsemisen laatuun ja tuloksiin.

DetectEncoding

Lippu, joka pakottaa moottorin tunnistamaan tekstin koodauksen Unicode-merkkejä varten. Oletusarvo on true.

[XmlSerialization(Type = XmlSerializationType.Element)]
public bool DetectEncoding { get; set; }

Returns

Returns

Returns

Tämä esimerkki näyttää, miten tekstin merkistökoodaus tunnistetaan reaaliaikaisesti, kun DetectEncoding on käytössä.

using (MemoryStream ms = new MemoryStream())
{
    using (BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR))
    {
        generator.SetCodeText("Слово", Encoding.UTF8);
        generator.Save(ms, BarCodeImageFormat.Png);
    }
    //detects encoding for Unicode codesets is enabled
    ms.Position = 0;
    using (BarCodeReader reader = new BarCodeReader(ms, DecodeType.QR))
    {
        reader.BarcodeSettings.DetectEncoding = true;
        foreach (BarCodeResult result in reader.ReadBarCodes())
            Console.WriteLine("BarCode CodeText: " + result.CodeText);
    }
    //detect encoding is disabled
    ms.Position = 0;
    using (BarCodeReader reader = new BarCodeReader(ms, DecodeType.QR))
