Public API and Backward Incompatible Changes

Enum BarCodeReadType has been marked as [OBSOLETE]

Since enum BarCodeReadType allows us to support only first 62 symbologies, new type has been added, and it is highly recommended to use new type called DecodeType instead.

BarCodeReadType will be unavailable within two months term.

New types have been added to support more BarCode types

DecodeType, BaseDecodeType, SingleDecodeType, MultyDecodeType

These types will be further used in BarCodeReader instead of BarCodeReadType.

Create single decode type

 SingleDecodeType singleType = DecodeType.QR

Creates compound MultyDecode types that combine SingleDecodeType and MultiDecode types.

 MultyDecodeType types1 = new MultyDecodeType(DecodeType.QR, DecodeType.DATA_MATRIX);

MultyDecodeType types2 = new MultyDecodeType(types1, DecodeType.CODE_128, DecodeType.CODE_39_STANDARD);
Namespaces have been updated

Public Namespaces have been re-arranged according to Microsoft guidelines.

The namespace com.aspose.barcoderecognition has been replaced with com.aspose.barcode.barcoderecognition; barcode.common has been replaces with com.aspose.barcode.common.

Thus, the namespaces com.aspose.barcoderecognition, barcode.common are not available anymore.

BARCODENET-34399 Add a manual hint “SkipRotatedBarcodes”

New manual hint has been added to the available API: SkipRotatedBarcodes

It turns off rotation algorithms, and  therefore, increases the recognition speed. It is available only for Datamatrix and the linear barcodes. Code sample

 long s = System.currentTimeMillis();

String filename = folder + "/Datamatrix12.jpg";

BarCodeReader reader = new BarCodeReader(filename, BarCodeReadType.GS1DataMatrix);

System.out.println("Skip rotated barcodes");

reader.setRecognitionMode(RecognitionMode.ManualHints);

reader.setManualHints(ManualHint.SkipRotatedBarcodes);

while (reader.read())

{

   System.out.println(reader.getReadType() + ": " + reader.getCodeText() + " QA:" + reader.getRecognitionQuality());

}

long res1 = System.currentTimeMillis() - s;

System.out.println(res1);

System.out.println();

s = System.currentTimeMillis();

reader = new BarCodeReader(filename, BarCodeReadType.GS1DataMatrix);

System.out.println("Not skip rotated barcodes");


while (reader.read())

{

    System.out.println(reader.getReadType() + ": " + reader.getCodeText() + " QA:" + reader.getRecognitionQuality());

}

long res2 = System.currentTimeMillis() - s;

System.out.println(res2);

Result:

 Skip rotated barcodes

DataMatrix: Wikipedia on erinomainen tietosanakirja, josta l?¶ytyy paljon tietoa mm. viivakoodeista. QA:0

Time: 116ms.

Time: 436ms.
BARCODENET-34368 Add new BarCode type: MICR (only reader)

New barcode type MICR has been added*.*

It is available only as a feature of BarCodeReader class. Code sample

 BarCodeReader reader = new BarCodeReader("MICR.jpg", BarCodeReadType.MicrE13B);

while (reader.read())

{

    System.out.println(reader.getReadType() + ": " + reader.getCodeText());

}

Result:

 A011234567A001234567C243
BARCODENET-34364 Add new BarCode type: Datalogic2of5Code

Code sample (Generate)

 BarCodeBuilder builder = new BarCodeBuilder("8500060000", Symbology.DataLogic2of5);

builder.save("DataLogic2of5.png");

Code sample (Recognize)

 BarCodeReader reader = new BarCodeReader("DataLogic2of5.png", DecodeType.DataLogic2of5);

while (reader.read())

{

    System.out.println(reader.getDecodeType() + ": " + reader.getCodeText());

}

Result:

 DataLogic2of5: 8500060000
BARCODENET-34363 Add new BarCode type: Code32

New barcode type Code32 has been added. Code sample (Generate)

 BarCodeBuilder builder = new BarCodeBuilder("123456788", Symbology.Code32);

builder.save("code32.png");

Code sample (Recognize)

 BarCodeReader reader = new BarCodeReader("code32.png", BarCodeReadType.Code32))

while (reader.read())

{

    System.out.println(reader.getReadType() + ": " + reader.getCodeText());

}

Result:

  Code32: 123456788
