此示例显示如何将 QualitySettings 与 BarCodeReader 一起使用

[C#]
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39Standard, DecodeType.Code128))
{
   //设置高性能模式
   reader.QualitySettings = QualitySettings.HighPerformance;
   foreach (BarCodeResult result in reader.ReadBarCodes())
      Console.WriteLine("BarCode CodeText: " + result.CodeText);
}
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39Standard, DecodeType.Code128))
{
   //默认设置正常质量模式
   foreach (BarCodeResult result in reader.ReadBarCodes())
      Console.WriteLine("BarCode CodeText: " + result.CodeText);
}
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39Standard, DecodeType.Code128))
{
   //设置高性能模式
   reader.QualitySettings = QualitySettings.HighPerformance;
   //设置单独的选项
   reader.QualitySettings.AllowMedianSmoothing = true;
   reader.QualitySettings.MedianSmoothingWindowSize = 5;
   foreach (BarCodeResult result in reader.ReadBarCodes())
      Console.WriteLine("BarCode CodeText: " + result.CodeText);
}
[VB.NET]
Using reader As New BarCodeReader("c:\test.png", DecodeType.Code39Standard, DecodeType.Code128)
    '设置高性能模式
    reader.QualitySettings = QualitySettings.HighPerformance
    For Each result As BarCodeResult In reader.ReadBarCodes()
        Console.WriteLine("BarCode Type: " + result.CodeTypeName)
    Next
End Using
Using reader As New BarCodeReader("c:\test.png", DecodeType.Code39Standard, DecodeType.Code128)
    '默认设置正常质量模式
    For Each result As BarCodeResult In reader.ReadBarCodes()
        Console.WriteLine("BarCode Type: " + result.CodeTypeName)
    Next
End Using
Using reader As New BarCodeReader("c:\test.png", DecodeType.Code39Standard, DecodeType.Code128)
   '设置高性能模式
   reader.QualitySettings = QualitySettings.HighPerformance
   '设置单独的选项
   reader.QualitySettings.AllowMedianSmoothing = True
   reader.QualitySettings.MedianSmoothingWindowSize = 5
   For Each result As BarCodeResult In reader.ReadBarCodes()
       Console.WriteLine("BarCode Type: " + result.CodeTypeName)
   Next
End Using
