Public API and Backward Incompatible Changes

QualitySettings API

Added new Enums:

  • com.aspose.barcode.barcoderecognition.XDimensionMode (AUTO,SMALL,NORMAL,LARGE,USE_MINIMAL_X_DIMENSION),
  • com.aspose.barcode.barcoderecognition.BarcodeQualityMode (HIGH/NORMAL/LOW),
  • com.aspose.barcode.barcoderecognition.DeconvolutionMode (FAST/NORMAL/SLOW),
  • com.aspose.barcode.barcoderecognition.InverseImageMode (AUTO/DISABLED/ENABLED),
  • com.aspose.barcode.barcoderecognition.ComplexBackgroundMode (AUTO/DISABLED/ENABLED).

Added new QualitySettings methods:

  • setXDimension(XDimensionMode) - Recognition mode which sets size (from 1 to infinity) of barcode minimal element: matrix cell or bar.
  • getXDimension():XDimensionMode - Recognition mode which sets size (from 1 to infinity) of barcode minimal element: matrix cell or bar.
  • setMinimalXDimension(float) - Minimal size of XDimension in pixels which is used with UseMinimalXDimension.
  • getMinimalXDimension():float - Minimal size of XDimension in pixels which is used with UseMinimalXDimension.
  • setBarcodeQuality(BarcodeQualityMode) - Mode which enables methods to recognize barcode elements with the selected quality. Barcode element with lower quality requires more hard methods which slows the recognition.
  • getBarcodeQuality():BarcodeQualityMode - Mode which enables methods to recognize barcode elements with the selected quality. Barcode element with lower quality requires more hard methods which slows the recognition.
  • setDeconvolution(DeconvolutionMode) - Deconvolution (image restorations) mode which defines level of image degradation.
  • getDeconvolution():DeconvolutionMode - Deconvolution (image restorations) mode which defines level of image degradation.
  • setInverseImage(InverseImageMode) - Mode which enables or disables additional recognition of barcodes on images with inverted colors (luminance).
  • getInverseImage():InverseImageMode - Mode which enables or disables additional recognition of barcodes on images with inverted colors (luminance).
  • setComplexBackground(ComplexBackgroundMode) - Mode which enables or disables additional recognition of color barcodes on color images.
  • getComplexBackground():ComplexBackgroundMode - Mode which enables or disables additional recognition of color barcodes on color images.

Added new QualitySettings methods (presets):

  • getHighPerformance() - HighPerformance recognition quality preset. High quality barcodes are recognized well in this mode.
  • getNormalQuality() - NormalQuality recognition quality preset. Suitable for the most of barcodes.
  • getHighQuality() - HighQuality recognition quality preset. This preset is developed for low quality barcodes. Allows to detect highly damaged barcodes.
  • getMaxQuality() - MaxQuality recognition quality preset. This preset is developed to recognize all possible barcodes, even incorrect barcodes.

Following QualitySettings API members were removed:

  • getMaxBarCodes(),
  • getHighQualityDetection(),
  • getMaxQualityDetection().
  • get/setAllowInvertImage,
  • get/setReadTinyBarcodes,
  • get/setCheckMore1DVariants,
  • get/setAllowComplexBackground,
  • get/setAllowMedianSmoothing,
  • get/setMedianSmoothingWindowSize,
  • get/setAllowRegularImage,
  • get/setAllowDecreasedImage,
  • get/setAllowWhiteSpotsRemoving,
  • get/setAllowOneDAdditionalScan,
  • get/setAllowOneDFastBarcodesDetector,
  • get/setFastScanOnly,
  • get/setAllowMicroWhiteSpotsRemoving,
  • get/setAllowSaltAndPaperFiltering,
  • get/setAllowDetectScanGap,
  • get/setAllowDatamatrixIndustrialBarcodes,
  • get/setAllowQRMicroQrRestoration,
  • get/setUseOldBarcodeDetector,
  • get/setAllowAdditionalRestorations,
  • get/setAllowOneDWipedBarsRestoration,
  • setDetectorSettings(BarcodeSvmDetectorSettings),
  • getDetectorSettings():BarcodeSvmDetectorSettings, Following BarcodeSvmDetectorSettings API members were removed:
  • ScanWindowSizes,
  • SimilarityCoef,
  • RegionLikelihoodThresholdPercent,
  • SkipDiagonalSearch,
  • HighPerformance,
  • NormalQuality,
  • HighQuality,
  • MaxQuality.

Micro QR and rMQR codes

Added enums com.aspose.barcode.generation.MicroQRVersion com.aspose.barcode.generation.RectMicroQRVersion Following members were added to com.aspose.barcode.barcoderecognition.DecodeType RECT_MICRO_QR:SingleDecodeType and MICRO_QR:SingleDecodeType Following members were added to com.aspose.barcode.generation.EncodeTypes RECT_MICRO_QR:SymbologyEncodeType MICRO_QR:SymbologyEncodeType New methods were added to com.aspose.barcode.generation.QrParameters getRectMicroQrVersion():RectMicroQRVersion setRectMicroQrVersion(RectMicroQRVersion) getMicroQRVersion():MicroQRVersion setMicroQRVersion(MicroQRVersion)

Sample RectMicroQR generation and recognition code:

public void example1()
{
    String codetext = "Aspose";
    BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.RECT_MICRO_QR, codetext);
    {
        generator.getParameters().getBarcode().getCodeTextParameters().setLocation(CodeLocation.BELOW);
        generator.getParameters().getBarcode().getQR().setRectMicroQrVersion(R11x77);
        BufferedImage image = generator.generateBarCodeImage();
        BarCodeReader reader = new BarCodeReader(image, DecodeType.RECT_MICRO_QR);
        BarCodeResult[] barCodeResults = reader.readBarCodes();
        System.out.println("Codetext: " + reader.getFoundBarCodes()[0].getCodeText());
    }
}

Sample MicroQR generation and recognition code:

public void example2()
{
    String codetext = "Aspose";
    BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.MICRO_QR, codetext);
    {
        generator.getParameters().getBarcode().getQR().setMicroQRVersion(M4);
        BufferedImage image = generator.generateBarCodeImage();
        BarCodeReader reader = new BarCodeReader(image, DecodeType.MICRO_QR);
        BarCodeResult[] barCodeResults = reader.readBarCodes();
        System.out.println("Codetext: " + reader.getFoundBarCodes()[0].getCodeText());
    }
}
