Dynamsoft Barcode Reader 7.4

Adds support for DotCode barcode format.
April 20, 2020 - 10:14
New Version


  • Added new barcode format support for DotCode.
  • Added relative ROI (Region of Interest) detection to optimize the localization results in the high colour contrasted scenarios.
  • Added a new type of output IRT_PREDETECTED_QUADRILATERAL, to identify regions with user-define HSV colour space.
  • Implemented a feature for recognizing distorted DataMatrix barcodes. It can be enabled by turning on the struct PublicRuntimeSettings -> furtherMode -> DeformationResistingModes.
  • Added an optimized decoding method for linear barcodes in vector PDF files. The vector PDF file can be decoded without rasterizing, increase decoding efficiency.
  • Added two Enumerations for FrameDecodingParameters: ClarityCalculationMethod and ClarityFilterMode, to improve input image quality.
  • Enhanced QR Code deformation, resistance, to improve the success rate of decoding the QR code with square symbol at the center.
  • Optimized the algorithm for decoding large and dense QR and DataMatrix codes.
  • Optimized deblurring algorithm for linear barcodes.
  • Combined Windows and Linux Java libraries into one JAR file to support both platforms. The JAR file is also available on Dynamsoft server for developers to add dependencies easily via Maven repositories.
  • Improved a character display issue on some platforms where BarcodeText returns an extra "\uFEFF" if the barcode is encoded in UTF-8 with BOM (Byte Order Mark).
  • Simplified the process to enable DPM, DotCode and Postal Codes. Now the library will automatically turn on the corresponding localization mode while following settings are applied:


  • Fixed a bug where the BinarizationModes settings do not work in the DPM mode.
  • Fixed a bug where the barcode location returns incorrect when the barcode is close to the border of the scanning region.
  • Fixed a bug in the calculation of deblur confidence.
  • Fixed a bug where the ColourConversionModes RGB weights setting does not work when CICM_GENERAL is enabled.
