Release Notes for JavaScript SDK - 8.x

8.1.2 (01/22/2021)

New

• Added mode, page, totalPage and parityData in the QRCodeDetails Class.

Improved

• Improved the recognition accuracy for GS1 Databar.
• Removed the exception code from barcodeText when using a valid trial license.
• Optimized memory usage when using WebGL for mapping color images into grayscale images which made the process faster.

Fixed

• Fixed a bug where barcodeFormatString, barcodeFormatString_2, regionName and documentName don’t have value in the IRT_TYPED_BARCODE_ZONE intermediate result.

8.1 (01/19/2021)

New

• Added support for MSI Code (Modified Plessey).
• Added a new member BarcodeZoneMinDistanceToImageBorders in the PublicRuntimeSettings struct to set the minimum distance (in pixels) between barcode zone and image borders.
• Added exception error message to TextResult when license initialization fails or decoding authorization fails.

Improved

• Improved the localization robustness for QR Code.
• Improved the localization for low quality 1D barcodes.
• Improved the deblurring performance and recognition rate for DataMatrix.
• Improved the recognition rate for Aztec.
• Improved runtime setting presets to use BarcodeZoneMinDistanceToImageBorders.

Fixed

• Fixed a bug where Micro PDF417 may not be localized in multiple-barcode scenarios.
• Fixed a bug where the ExpectedBarcodesCount and BarcodeFormat parameters do not work in the RegionDefinition.
• Fixed a memory issue in iOS Safari caused by enabling sound.
• Fixed an issue with UTF-8 character encoding.

8.0 (11/25/2020)

New

• Added support for decoding barcodes from an existing video stream.
• Introduced new namespace Dynamsoft.DBR.
• Implemented a new licensing tracking mechanism, License 2.0, which makes it easier for users to track license usage.
• Added a new format control parameter, BarcodeZoneMinDistanceToImageBorders, to set the minimum distance (in pixels) between the barcode zone and image borders.
• Added a new format control parameter, MinRatioOfBarcodeZoneWidthToHeight, to set the minimum ratio (width/height) of the barcode zone.
• Added a new format control parameter, BarcodeZoneBarCountRangeArray, to set the barcode zone’s range of bar count for barcode search.
• Added a new argument, SpatialIndexBlockSize, for RPM_GENERAL_RGB_CONTRAST, RPM_GENERAL_GRAY_CONTRAST and RPM_GENERAL_HSV_CONTRAST.
• Added a new parameter, DeblurModes, so users can use different deblur algorithms for different scenarios. DeblurModes has the following enum types: DirectBinarization, ThresholdBinarization, GrayEqulization, Smoothing, Morphing, DeepAnalysis and Sharpening.

Improved

• Changed the default runtime preset setting of BarcodeScanner from speed to single.
• Improved the localization speed for the ScanDirectly mode.
• Improved the localization accuracy for DataMatrix codes with a narrow quiet zone.

Fixed

Feature Deprecated

• DeblurLevel is now deprecated. It still works in this version but could be removed in the near future. We recommend using DeblurModes instead.
