End UsingProcessorSettings
Er erhält eine Einstellung der Verwendung von Prozessorkoren.
public static ProcessorSettings ProcessorSettings { get; }Eigentumswert
Examples
Dieses Muster zeigt, wie Sie ProcessorSettings verwenden, um maximale Multi-Thread-Performance hinzuzufügen
//this allows to use all cores for single BarCodeReader call
BarCodeReader.ProcessorSettings.UseAllCores = true;
//this allows to use current count of cores
BarCodeReader.ProcessorSettings.UseAllCores = false;
BarCodeReader.ProcessorSettings.UseOnlyThisCoresCount = Math.Max(1, Environment.ProcessorCount / 2);
'this allows to use all cores for single BarCodeReader call
BarCodeReader.ProcessorSettings.UseAllCores = True
'this allows to use current count of cores
BarCodeReader.ProcessorSettings.UseAllCores = False
BarCodeReader.ProcessorSettings.UseOnlyThisCoresCount = Math.Max(1, Environment.ProcessorCount / 2)QualitySettings
QualitySettings ermöglicht es, die Erkennungsqualität und Geschwindigkeit manuell zu konfigurieren.Sie können Qualitätsinstellungen schnell durch eingebettete Pre-Sets einrichten: HighPerformance, NormalQuality,HighQuality, MaxBarCodes oder Sie können manuell separate Optionen konfigurieren.Der Standardwert von QualitySettings ist NormalQuality.
[XmlSerialization(Type = XmlSerializationType.Element)]
public QualitySettings QualitySettings { get; set; }Eigentumswert
