BARCODENET-33812 Add support to encode GS1QR code

Code sample:

 string text =

"(01)04912345123459(15)970331(30)128(10)ABC123"

;

BarCodeBuilder builder = new BarCodeBuilder(text, Symbology.GS1QR);

builder.Save(@

"GS1QR.png"

, BarCodeImageFormat.Png);

BARCODENET-34310 Implement GS1 QR decoding

Code sample

 using (BarCodeReader reader = new BarCodeReader(

"GS1QR.png"

, BarCodeReadType.GS1QR))

{

while (reader.Read()){

		Console.WriteLine(reader.GetReadType() +

": "

\+ reader.GetCodeText());

	}

}

Result:

GS1QR: (01)04912345123459(15)970331(30)128(10)ABC123

BARCODENET-34319 DataBarStackedOmniDirectional encoding, BarCodeBuilder.BarHeight property does not work properly

Code sample:

 BarCodeBuilder b = new BarCodeBuilder(

"(01)90013670000396(3200)15(11)150819"

);

b.SymbologyType = Symbology.DatabarStackedOmniDirectional;

b.xDimension = 0.330f;

b.BarHeight = 27.77f;

b.Resolution = new Resolution(1200.0f, 1200.0f, ResolutionMode.Customized);

b.Save(

"Barheight.png"

, BarCodeImageFormat.Png);

Results in case of resolution 1200:

BARCODENET-34311 Unwanted White Space at the bottom of Barcode Image

Code sample

 BarCodeBuilder builder = new BarCodeBuilder()

{

SupplementSpace = 0,

CodeTextSpace = 0,

Margins = new MarginsF(0, 0, 0, 0),

SymbologyType = Symbology.EAN13,

CodeText =

"000080283188"

,

};

builder.Save(@

"image.bmp"

);

To set barcode height or width, please use BarHeight and xDimension properties.


Changing ImageHeight or ImageWidth will not affect the barcode size,


but Only image size will be affected, in case Autosize has been set to false.

BARCODENET-34309 Reorganize the logic of recognition in manual hint mode to speed up the detection

The calculated time using manual hints must be lesser than using max quality mode.

Code sample (manual hints )

 Stopwatch watch = new Stopwatch();

string filename = @

"Untitled22.jpg"

;

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

{

watch.Start();

reader.RecognitionMode = RecognitionMode.ManualHints;

reader.ManualHints = ManualHint.MedianSmoothing;

while (reader.Read()){

		Console.WriteLine(reader.GetReadType() +

": "

\+ reader.GetCodeText());

	}

watch.Stop();

Console.WriteLine(

"Time: "

\+ watch.ElapsedMilliseconds +

"ms."

);

}

Result:

DataMatrix: :AAAAvGg0ByEJ9w\|ac

Time: *2344ms*.

Code sample (max quality mode):

{code:xml}


Stopwatch watch = new Stopwatch();

string filename = @

"Untitled22.jpg"

;

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

{

watch.Start();

reader.RecognitionMode = RecognitionMode.MaxQuality;

while (reader.Read()){

		Console.WriteLine(reader.GetReadType() +

": "

\+ reader.GetCodeText());

	}

watch.Stop();

Console.WriteLine(

"Time: "

\+ watch.ElapsedMilliseconds +

"ms."

);

}

Result:

DataMatrix: :AAAAvGg0ByEJ9w\|ac

Time: *6003ms*.

BARCODENET-34295 AI Codes Not Accepting Valid Values for GS1DataMatrix

Code sample:

BarCodeBuilder builder = new BarCodeBuilder(

"(01)90013670000396(3400)123456"

); // Or any of the above values

builder.SymbologyType = Symbology.GS1DataMatrix;

builder.Save(

"GS1DataMatrix.png"

, BarCodeImageFormat.Png);

BARCODENET-34294 AI Codes Not Accepting Valid Values for GS1Code128

Code sample:

BarCodeBuilder b = new BarCodeBuilder(

"(01)90013670000396(3400)123456"

); // Or any of the above values

b.SymbologyType = Symbology.GS1Code128; // Or GS1DataMatrix

b.Save(

"OutGS1Code128.png"

, BarCodeImageFormat.Png);

BARCODENET-34292 Barcode Reader skips a binary character

Code sample

BarCodeReader reader = new BarCodeReader(@

"TestY.jpg"

,BarCodeReadType.Pdf417);

reader.Read();

byte\[\] bytes = reader.GetCodeBytes();

// bytes to hex

StringBuilder sb = new StringBuilder();

for (int i = 0; i < bytes.Length; i++)

{

if (i%16 == 0)

sb.AppendLine();

sb.Append(Convert.ToString(bytes[i], 16).PadLeft(2, '0') +

" "

);

}

Console.WriteLine(sb.ToString());

BARCODENET-33843 Can’t recognize all DataMatrix/Code128 codes from a tif file

Improved recognition.

Now we can recognize all DataMatrix barcode (without MaxQuality).

Sample code:

 int

count = 0;

using (BarCodeReader reader =

new

BarCodeReader(imgPath, BarCodeReadType.DataMatrix))

{

while

(reader.Read()){

        count++;

        Console.WriteLine(count +

" - Code Text: "

\+ reader.GetCodeText() +

" - Type: "

\+ reader.GetReadType());

About Code128


We can not recognize Code128 barcodes, but we have several fakes (4 fakes).



Sample code:

int

count = 0;

using (BarCodeReader reader =

new

BarCodeReader(imgPath, BarCodeReadType.DataMatrix \| BarCodeReadType.Code128))

{

while

(reader.Read()){

        count++;

        Console.WriteLine(count +

" - Code Text: "

\+ reader.GetCodeText() +

" - Type: "

\+ reader.GetReadType());
