Nouvelle Version

Fonctionnalités

  • Added support for QR Code Model 1 (an older version of the QR Code specification). It can be enabled by setting FormatSpecification.EnableQRCodeModel1 in the JSON template file.
  • Added a new localization mode LM_CENTRE to localize barcodes from the centre, which can improve the localization speed if the barcode is in the centre of the image. It can be enabled by setting the struct PublicRuntimeSettings -> LocalizationModes -> LM_CENTRE.
  • Added a new binarization mode BM_THRESHOLD to set the BinarizationThreshold value which is used to convert the grayscale image to binary image.
  • Added startPatternRange, middlePatternRange and endPatternRange properties to the struct OneDCodeDetails for UPC_A, UPC_E, EAN_8 and EAN_13 codes.
  • Added the following new arguments for RegionPredetectionMode.RPM_GENERAL_RGB_CONTRAST and RegionPredetectionMode.RPM_GENERAL_GRAY_CONTRAST:
    • RelativeBarcodeRegions: Sets the barcode regions relative to the pre-detected region.
    • ForeAndBackgroundColours: Specifies a set (or multiple sets) of the foreground and background colours used for region pre-detection algorithm.
    • AspectRatioRange: Sets the height range of the bounding rectangle of the pre-detected region.
    • HeightRange: Sets the width range of the bounding rectangle of the pre-detected region.
    • WidthRange: Sets the aspect ratio range of the bounding rectangle of the pre-detected region.
  • Optimized the binarization process for 1D barcode zones.
  • Improved the decoding accuracy for 1D barcodes.
  • Improved the decoding speed by 5%-20%.
  • Improved the decoding accuracy for Data Matrix code with broken finder pattern.

Correctifs

  • Fixed a bug where the coordinates of barcodes are calculated incorrectly under some situations.
