New

  • Added a new method getInstancePoolStatus and class InstancePoolStatus to provide a real-time view of how the concurrent instance licenses are being utilized. This applies only if you are using a concurrent instance license.

  • Improved the performance of Direct Part Marking (DPM) barcode decoding.
  • Improved the performance of GS1 Databar barcode decoding.

Fixed

  • Fixed a crash bug when using a online license key on ARM64 environment.

  • Fixed a bug that some OneD barcodes without start & stop characters are not decoded when parameter RequireStartStopChars is set to 0.
  • Other small fixes and tweaks.

9.6.0 (11/29/2022)

Version Highlights

  • Image orientation handling is supported by a new feature. With the new feature, you can:
    • Get a TranformationMatrix along with the barcode location result.
    • Implement coordinates transformation on the barcode location result with the TransformationMatrix.
  • DotCode decoding is improved by optimizing the localization of DotCodes that are close to one another.
  • EAN8 barcode decoding is improved by honing the accuracy of localization algorithms.
  • QR code localizing is improved by reducing the mis-assemble rate of the finder patterns when using the localization mode LM_CONNECTED_BLOCK or LM_SCAN_DIRECTLY, which are designed for speed. The mis-assembling only occurs when there exist dense QR codes on the same image.
  • Mirrored rectangular DataMatrix barcode is supported by implementing MirrorMode when localizing the barcodes.
  • Deformed barcode decoding is improved by extending the supported modes and mode arguments of DeformationResistingModes.

Edition Highlights

  • Added duplicate barcode filter feature in video mode. You can implement duplicate filter to ignore duplicate barcodes for a period.

Changelog

New

  • Added a property orientation to class FrameDecodingParameters to set the orientation information of the video frame.
  • Added orientation to class ImageData to set the orientation information.
  • Enabled decoding methods decodeFile(), decodeFileinMemory() and decodeBase64String() to read EXIF data of the given image so that the library can obtain the orientation information of the image file.
  • Overloaded method decodeBuffer() with a new parameter orientation to set the orientation information of the image data.
  • Added a property transformationMatrix to class LocalizationResult so that the library can output a transformation matrix for transforming the localization coordinates to image’s natural orientation.
  • Added a method transformCoordinates() to support transforming the coordinates of a point based on a given transformation matrix.
  • Added a property duplicateForgetTime to class FrameDecodingParameters to set the time period used to filter out duplicate results found in frames.
  • Added a callback method uniqueBarcodeCallback() to interface TextResultCallback which will be triggered when the library finishes decoding a frame and finds unique barcodes.
  • Added properties hasLeftRowIndicator and hasRightRowIndicator to class PDF417Details to return whether the left and right row indicator of the PDF417 barcode is detected.
  • Added a member BF2_ALL to enumeration BarcodeFormatIds_2 to support setting all barcode formats in BarcodeFormat group 2 with one enumeration.
  • Extended the features of parameter DeformationResistingModes:
    • Extended the valid mode arguments of DRM_BROAD_WARP, DRM_LOCAL_REFERENCE and DRM_DEWRINKLE with two new arguments: GrayscaleEnhancementMode and BinarizationMode.
    • Supported mode DRM_AUTO.

Improved

  • Improved the accuracy when processing multiple QR codes.
  • Improved the processing speed by excluding incorrectly located barcode zones before decoding.
  • Improved the creation, destruction and acquisition logic of concurrent instances.
  • Improved the accuracy of EAN8 localization result(s).
  • Improved the localization of mirrored DataMatrix barcode by implementing MirrorMode.

Fixed

  • Fixed a bug that DotCodes might not be decoded when they are densely arranged.

9.4.0 (08/30/2022)

Highlights

  • DotCode decoding has been improved by optimizing the localization and decoding algorithm.

9.2.0 (06/07/2022)

Version Highlights

  • Barcode boundary-seeking algorithm is refactored to improve stability.
  • Pharmacode decoding is optimized to improve accuracy.
  • The function of device-alias is added to allow users to give each device a readable name. For end-users and administrators, this makes it more friendly to distinguish between devices about license usage statistics.
