此示例显示如何使用 QualitySettings 与 BarCodeReader

//set HighPerformance recogition mode
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39Extended, DecodeType.Code128))
{
    reader.QualitySettings = QualitySettings.HighPerformance;
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

//set HighQuality recognition mode
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39Extended, DecodeType.Code128))
{
    reader.QualitySettings = QualitySettings.HighQuality;
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

//set HighPerformance recogition mode for low sized barcodes
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39Extended, DecodeType.Code128))
{
    reader.QualitySettings = QualitySettings.HighPerformance;
    reader.QualitySettings.XDimension = XDimensionMode.Small;
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

//set HighPerformance recogition mode for low quality barcodes
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39Extended, DecodeType.Code128))
{
    reader.QualitySettings = QualitySettings.HighPerformance;
    reader.QualitySettings.BarcodeQuality = BarcodeQualityMode.Low;
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

Properties

AllowIncorrectBarcodes

允许发动机识别错误的条码或错误的值,模式可以用来识别错误的条码。

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