All Changes

Public API and Backward Incompatible Changes

QualitySettings API

Added new enums:

• Recognition.XDimensionMode (values AUTO,SMALL,NORMAL,LARGE,USE_MINIMAL_X_DIMENSION),
• Recognition.BarcodeQualityMode (values HIGH/NORMAL/LOW),
• Recognition.DeconvolutionMode (values FAST/NORMAL/SLOW),
• Recognition.InverseImageMode (values AUTO/DISABLED/ENABLED),
• Recognition.ComplexBackgroundMode (values AUTO/DISABLED/ENABLED).

Added new Recognition.QualitySettings methods:

• setXDimension(value) - Recognition mode which sets size (from 1 to infinity) of barcode minimal element: matrix cell or bar.
• getXDimension() - Recognition mode which sets size (from 1 to infinity) of barcode minimal element: matrix cell or bar.
• setMinimalXDimension(value) - Minimal size of XDimension in pixels which is used with UseMinimalXDimension.
• getMinimalXDimension() - Minimal size of XDimension in pixels which is used with UseMinimalXDimension.
• setBarcodeQuality(value) - 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() - 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(value) - Deconvolution (image restorations) mode which defines level of image degradation.
• getDeconvolution() - Deconvolution (image restorations) mode which defines level of image degradation.
• setInverseImage(value) - Mode which enables or disables additional recognition of barcodes on images with inverted colors (luminance).
• getInverseImage() - Mode which enables or disables additional recognition of barcodes on images with inverted colors (luminance).
• setComplexBackground(value) - Mode which enables or disables additional recognition of color barcodes on color images.
• getComplexBackground() - Mode which enables or disables additional recognition of color barcodes on color images.
• setAllowIncorrectBarcodes(value) - Mode which allows engine to recognize barcodes which has incorrect checksumm or incorrect values.
• getAllowIncorrectBarcodes() - Mode which allows engine to recognize barcodes which has incorrect checksumm or incorrect values.

Added new QualitySettings methods (presets):

• getHighPerformance(): QualitySettings - HighPerformance recognition quality preset. High quality barcodes are recognized well in this mode.
• getNormalQuality(): QualitySettings - NormalQuality recognition quality preset. Suitable for the most of barcodes.
• getHighQualityDetection(): QualitySettings - HighQuality recognition quality preset. This preset is developed for low quality barcodes. Allows to detect highly damaged barcodes.
• getMaxQualityDetection(): QualitySettings - 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/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 Generation.MicroQRVersion (values AUTO,M1,M2,M3,M4) Generation.RectMicroQRVersion (values AUTO,R7x43,R7x59,R7x77,R7x99,R7x139,R9x43,R9x59,R9x77,R9x99,R9x139,R11x27,R11x43,R11x59,R11x77,R11x99,R11x139,R13x27,R13x43,R13x59,R13x77,R13x99,R13x139,R15x43,R15x59,R15x77,R15x99,R15x139,R17x43,R17x59,R17x77,R17x99,R17x139 ) Following members were added to class Recognition.DecodeType const RECT_MICRO_QR const MICRO_QR Following members were added to Generation.EncodeTypes const RECT_MICRO_QR const MICRO_QR New methods were added to Generation.QrParameters getRectMicroQrVersion():RectMicroQRVersion setRectMicroQrVersion(RectMicroQRVersion) getMicroQRVersion():MicroQRVersion setMicroQRVersion(MicroQRVersion)

Sample RectMicroQR generation and recognition code:

        let codetext = "Aspose";
        let generator = new BarcodeGenerator(EncodeTypes.RECT_MICRO_QR, codetext);
        generator.getParameters().getBarcode().getCodeTextParameters().setLocation(CodeLocation.BELOW);
        generator.getParameters().getBarcode().getQR().setRectMicroQrVersion(RectMicroQRVersion.R11x77);
        let image = generator.generateBarCodeImage(BarCodeImageFormat.PNG);
        let reader = new BarCodeReader(image, null, DecodeType.RECT_MICRO_QR);
        let barCodeResults = reader.readBarCodes();
        let barCodeResult = barCodeResults[0];
        console.log('CodeText:' + barCodeResult.getCodeText());
        console.log('CodeType: ' + barCodeResult.getCodeTypeName());

Sample MicroQR generation and recognition code:

        let codetext = "Aspose";
        let generator = new BarcodeGenerator(EncodeTypes.MICRO_QR, codetext);
        generator.getParameters().getBarcode().getQR().setMicroQRVersion(MicroQRVersion.M4);
        let image = generator.generateBarCodeImage(BarCodeImageFormat.PNG);
        let reader = new BarCodeReader(image, null, DecodeType.MICRO_QR);
        let barCodeResults = reader.readBarCodes();
        let barCodeResult = barCodeResults[0];
        console.log('CodeText:' + barCodeResult.getCodeText());
        console.log('CodeType: ' + barCodeResult.getCodeTypeName());
