public final void setQualitySettings(QualitySettings value)
QualitySettings allows to configure recognition quality and speed manually. You can quickly set up QualitySettings by embedded presets: HighPerformance, NormalQuality, HighQuality, MaxBarCodes or you can manually configure separate options. Default value of QualitySettings is NormalQuality.
This sample shows how to use QualitySettings with BarCodeReader BarCodeReader reader = new BarCodeReader("c:\\test.png", DecodeType.CODE_39_STANDARD, DecodeType.CODE_128); //set high performance mode reader.setQualitySettings(QualitySettings.getHighPerformance()); for(BarCodeResult result : reader.readBarCodes()) System.out.println("BarCode CodeText: " + result.getCodeText()); BarCodeReader reader = new BarCodeReader("c:\\test.png", DecodeType.CODE_39_STANDARD, DecodeType.CODE_128); //normal quality mode is set by default for(BarCodeResult result : reader.readBarCodes()) System.out.println("BarCode CodeText: " + result.getCodeText()); BarCodeReader reader = new BarCodeReader("c:\\test.png", DecodeType.CODE_39_STANDARD, DecodeType.CODE_128); //set high performance mode reader.setQualitySettings(QualitySettings.getHighPerformance()); //set separate options reader.getQualitySettings().setAllowMedianSmoothing(true); reader.getQualitySettings().setMedianSmoothingWindowSize(5); for(BarCodeResult result : reader.readBarCodes()) System.out.println("BarCode CodeText: " + result.getCodeText());
Value: QualitySettings to configure recognition quality and speed.
