BarCodeConfidence

BarCodeConfidence enumeration

Contains recognition confidence level

public enum BarCodeConfidence

Values

Name	Value	Description
NONE	0	Recognition confidence of barcode where codetext was not recognized correctly or barcode was detected as posible fake
MODERATE	80	Recognition confidence of barcode (mostly 1D barcodes) with weak checksumm or even without it. Could contains some misrecognitions in codetext or even fake recognitions if is low
STRONG	100	Recognition confidence which was confirmed with BCH codes like Reed–Solomon. There must not be errors in read codetext or fake recognitions

Examples

//This sample shows how BarCodeConfidence changed, depending on barcode type
//Moderate confidence
let generator = new BarcodeGenerator(EncodeTypes.CODE_128, "12345");
generator.save("test.png");
let reader = new BarCodeReader("test.png", null,  [DecodeType.CODE_39, DecodeType.CODE_128]);
let results = reader.readBarCodes();
for(let i = 0; i < results.length; i++)
{
let result = results[i];
console.log("BarCode Type: " + result.getCodeTypeName());
console.log("BarCode CodeText: " + result.getCodeText());
console.log("BarCode Confidence: " + result.getConfidence());
console.log("BarCode ReadingQuality: " + result.getReadingQuality());
}

//Strong confidence
let generator = new BarcodeGenerator(EncodeTypes.QR, "12345");
generator.save("test.png");
let reader = new BarCodeReader("test.png", null,  [DecodeType.CODE_39, DecodeType.QR]);
let results = reader.readBarCodes();
for(let i = 0; i < results.length; i++)
{
let result = results[i];
console.log("BarCode Type: " + result.getCodeTypeName());
console.log("BarCode CodeText: " + result.getCodeText());
console.log("BarCode Confidence: " + result.getConfidence());
console.log("BarCode ReadingQuality: " + result.getReadingQuality());
}
