Release Notes for Dynamsoft Barcode Reader - 8.x

8.9

First released: 12-16-2021

Highlights

• Preset templates are available for users to configure the PublicRuntimeSettings parameters. Users can set the template via the method updateRuntimeSettings by specifying an EnumPresetTemplate member.

8.8

First released: 10-12-2021

Highlights

• Added a new localization mode ONED_FAST_SCAN, which significantly improved the localization speed for 1D barcodes.
• Added the ability to specify barcode width, height, angle to improve the recognition speed if you have advance information about barcodes.
• Optimized the logic of confidence scoring for 2D barcodes. The 2D barcode results with confidence greater than 30 are more accurate.

8.6

First released: 07-15-2021

Highlights

• Improved the confidence calculating algorithm for 1D barcodes. Misreading rate of results with confidence between 30-100 has been significantly reduced.
• Improved the reading speed on clear images by implementing a new deblur mode DM_BASED_ON_LOC_BIN.

8.4

First released: 06-08-2021

Highlights

• Added a new method GetIdleInstancesCount to return the number of available instances when using the ‘per concurrent instance’ licensing model.
• Added the organizationID property for license authentication.
• Added new attributes isMirrored to the TextResult class. IsMirrored returns whether the barcode is mirrored.
• Added a new argument, ThresholdCompensation, to the BinarizationModes mode arguments.
• Faster recognition speeds when detecting dense QR Codes.
• Improved the performance of boundary identification for DataMatrix codes.
• ThreshValueCoefficient is now deprecated. It still works in this version but could be removed in the near future. We recommend using ThresholdCompensation instead.
• Fixed an issue that happens when calling initLicenseFromLTS if handShakeCode is not set.

8.2

First released: 03-17-2021

Highlights

• Added a new mode argument, FindAccurateBoundary, to RegionPredetectionModes that determines if the SDK attempts to find an accurate boundary when RegionPredetectionModes is set to RPM_GENERAL_HSV_CONTRAST.
• Improved both the localization and decoding algorithms for Postal Codes.
• LocalizationMode LM_STATISTICS_POSTAL_CODE will not be added automatically when enabling Postal Code in your runtime settings. Instead, users must manually add it to the LocalizationMode array if it is required.
• Resolved a bug that infrequently causes the application to crash when decoding a MicroPDF417 barcode.

8.1

First released: 01-22-2021

Highlights

• 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. Previously, it is only available in the JSON template. It can be now configured by setting the struct PublicRuntimeSettings -> barcodeZoneMinDistanceToImageBorders.
• Added exception error message to TextResult when license initialization fails or decoding authorization fails.
• 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.
• 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.

8.0

First released: 11-17-2020

Highlights

• Implemented the mechanism of loading libraries dynamically at runtime when Parameter Mode Enumerations are used (except *_AUTO and *_SKIP). Use LibraryFileName and LibraryParameters to configure.
• (For IntermediateResult Advanced Module) Added support for decoding IntermediateResult. For example, users with a binarized image could use this function to skip some image preprocessing steps.
• 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 the localization speed for the ScanDirectly mode.
• Improved the localization accuracy for DataMatrix codes with a narrow quiet zone.
• Fixed a crash issue that could happen when conflicts occur on Linux.
• DeblurLevel is now deprecated. It still works in this version but could be removed in the near future. We recommend using DeblurModes instead.
