Usage examples:

The flag indicating that an unreadable barcode has been detected on the image

Code sample:

Bitmap lOrigBmp = new Bitmap(

"Path to File"

);

BarCodeReader reader = new BarCodeReader(lOrigBmp);

reader.SetBarCodeReadType(BarCodeReadType.QR);

//1.method max barcodes mode

reader.RecognitionMode = RecognitionMode.MaxBarCodes;

//2.method manual hints mode

//reader.RecognitionMode = RecognitionMode.ManualHints;

//reader.ManualHints = ManualHint.IncorrectBarcodes;

while (reader.Read())

{

bool isFake = reader.GetIsDeniable();

string lStr = reader.GetReadType().ToString() +

" IsFake:"

\+ isFake.ToString() +

" CodeText:"

\+ reader.GetCodeText();

MessageBox.Show(lStr);

}

lOrigBmp.Dispose();

Another sample:




string filename = @

"G:\prj\aspose\Barcode.Net\testdata\Issues\Issue34189\skipped2.png"

;

using (BarCodeReader reader = new BarCodeReader(filename, BarCodeReadType.Code128))

{

reader.RecognitionMode = RecognitionMode.MaxBarCodes;

while (reader.Read()){

          Console.WriteLine(reader.GetReadType() +

": "

\+ reader.GetCodeText());

          Console.WriteLine(

"IsDeniable: "

\+ reader.GetIsDeniable());

      }

}

Result:

Code128: A;000000014941 IsDeniable: True

Review and include  ECC000-140 algorithm into main project

"BASE-41 ONLY ALPHA, DIGITS AND PUNCTUATION."

;

builder1.Save(

"Barcode1.png"

);

BarCodeBuilder builder2 = new BarCodeBuilder();

builder2.SymbologyType = Symbology.DataMatrix;

builder2.DatamatrixEcc = DataMatrixEccType.Ecc050;

builder2.CodeText =

"ASCII encodes first 128 chars."

;

builder2.Save(

"Barcode2.png"

);

// Recognize

using (BarCodeReader reader = new BarCodeReader(

"Barcode1.png"

, BarCodeReadType.DataMatrix))

{

while (reader.Read()){

		Console.WriteLine(

"Barcode1.png:  "

\+ reader.GetCodeText());
