ChecksumValidation

Permet la validació del xec durant el reconeixement dels codis de barres 1D i Postal.

Default és tractat com Sí per a símbols que han de contenir el checksum, com No on el checksum només és possible.

Checksum mai utilitzat: Codabar, PatchCode, Pharmacode, DataLogic2of5

El preu és possible: Code39 Standard/Extended, Standard2of5, Interleaved2of5, ItalianPost25, Matrix2of5, MSI, ItalianPost25, DeutschePostIdentcode, DeutschePostLeitcode, VIN

Checksum sempre utilitzat: símbols de descans

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

Examples

Aquesta mostra mostra la influència de la Validació de Checksum sobre la qualitat del reconeixement i els resultats

using (BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.EAN13, "1234567890128"))
{
    generator.Save(@"c:\test.png");

DetectEncoding

La bandera que obliga el motor a detectar la codificació de text de codis per a units de codis Unicode.

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

Valor de la propietat

Examples

Aquesta mostra mostra com detectar el codificació de text en el vol si DetectEncoding és activat

using (MemoryStream ms = new MemoryStream())
{
    using (BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR))
    {
        generator.SetCodeText("Слово", Encoding.UTF8);
        generator.Save(ms, BarCodeImageFormat.Png);
