//This sample shows how to use QualitySettings with BarCodeReader
let reader = new BarCodeReader("test.png", null,  [ DecodeType.CODE_39, DecodeType.CODE_128 ]);
//set high performance mode
reader.setQualitySettings(QualitySettings.getHighPerformance());
let results = reader.readBarCodes();
for(let i = 0; i < results.length; i++)
{
let result = results[i];
console.log("BarCode CodeText: " + result.getCodeText());
}

let reader = new BarCodeReader("test.png", null,  [ DecodeType.CODE_39, DecodeType.CODE_128 ]);
//normal quality mode is set by default
let results = reader.readBarCodes();
for(let i = 0; i < results.length; i++)
{
let result = results[i];
console.log("BarCode CodeText: " + result.getCodeText());
}

let reader = new BarCodeReader("test.png", null,  [ DecodeType.CODE_39, DecodeType.CODE_128 ]);
//set high performance mode
reader.setQualitySettings(QualitySettings.getHighPerformance());
//set separate options
reader.getQualitySettings().setAllowMedianSmoothing(true);
reader.getQualitySettings().setMedianSmoothingWindowSize(5);
let results = reader.readBarCodes();
for(let i = 0; i < results.length; i++)
{
let result = results[i];
console.log("BarCode CodeText: " + result.getCodeText());
}
