Aspose.BarCode for Java 24.2 Release Notes

All Changes

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());
    }
}
