Release Notes

7.1 (08/15/2019)

New

• Added automatic blurry frame filtering for the video frame decoding, reducing incorrect barcode recognition.
• Added three arguments for the CICM_GENERAL of ColourConversionModes to set the weights for the color conversion, providing more flexibility to deal with various kinds of backgrounds by using different weights of three colors: red, green and blue.
• For C/C++ - Added a new struct FrameDecodingParameters, added methods DBR_InitFrameDecodingParameters()/InitFrameDecodingParameters(), and DBR_StartFrameDecodingEx()/StartFrameDecodingEx() to start a new thread to decode barcodes.
• For .NET - Added a new struct FrameDecodingParameters, added methods InitFrameDecodingParameters(), and StartFrameDecodingEx() to start a new thread to decode barcodes.

IMPROVED

• The output of intermediate results can be saved either directly to a folder or to memory or both, by introducing a new parameter, intermediateResultSavingMode, to the struct PublicRuntimeSettings.

FIXED

• Updated PDF component to v10.3.2.0806
• Fixed a bug that the deblur function might malfunction in some rare cases.
• Fixed a bug that the coordinates of barcodes may be calculated incorrectly under some situations.
• Fixed a bug that the parameter, RequireStartStopChars, might malfunction in some rare cases.
• Fixed a bug that the angle of barcodes might not be calculated correctly sometimes.
• Fixed a bug that GetIntermediateResults would throw exception “Value cannot be null.\r\nParameter name: destination”(for .NET version)
• Fixed a misspelling on Dynamsoft.Barcode.EnumBinarizationMode.BM_LOCAL_BLCOK(for .NET version)

7.0 (07/11/2019)

New

• Refactored most modules to provide a flexible barcode reading framework that allows for parameter customization suited for a variety of barcode scenarios.
• Enabled access to intermediate results (grayscale image, binarized image, text zone, etc) during the decoding process.
• Added new interfaces to support video decoding, and frame decoding to improve interactive sensitivity.
• Provided methods to terminate the decoding process at different phases such as during binarization, localization or barcode type identification.
• Added a new barcode localization method, Scan Directly, to reduce decoding time significantly for high-quality images.

IMPROVED

• Enhanced error messages related to the license initiation failure.
• Improved detailed results for decoded barcodes, including more barcode format specification.
• Improved results output to enable outputting barcode results in the order of confidence level, barcode position or format.

FIXED

• Fixed an issue where the barcode could be calculated incorrectly in some occasions.

6.5.3 (07/03/2019)

FIXED

• Updated the license verification process for development license and desktop runtime license. The old license verification process may lead to license error on some computers.
• Small fixes and tweaks.

6.5.2 (05/28/2019)

IMPROVED

• Optimized barcode reading workflow for QRCode/DataMatrix/Aztec code recognition. A QRCode/DataMatrix/Aztec barcode zone will be submitted to the deblurring process when its decoding results vary with different binarization arguments.
• Reduced the error rate of 1D barcode recognition. Giving more chances for confirmation of a 1D barcode decoding result whose confidence isn’t extreme high.
• Reduced the possibility of conflicts with neighbour barcodes. This improved the precision of the zone to be deleted when a barcode is recognized successfully.

FIXED

• [.NET only] Added a new Dispose method to help release resources in time in the BarcodeReader Class.
• Enhanced the robustness of the image processing algorithm. This resolved segmentation faults when a 0-size image is passed to our SDK or there are a few small-size barcode zones which need to do spatial transformation.

6.5.1 (04/16/2019)

IMPROVED

• Improved deblur algorithm for OneD, enhancing the recognition rate for blurry/out-of-focus barcodes.
• Improved the accuracy of border location and symbol segmentation for AZTEC.
• Optimized line scanning algorithm for OneD, decreasing the computation load for character recognition.
• DecodeBuffer now supports 48-bit and 64-bit image data.

FIXED

• Small fixes and tweaks.

6.5 (02/26/2019)

IMPROVED

• Improved average reading speed by 5-10%.
• Greatly improved the image-processing performance for blurry PDF417 codes.
• Improved decoding performance for blurry 1D, QRCode and DataMatrix codes.
• Decreased error recognition rate for Aztec codes.

FIXED

• Small fixes and tweaks.

6.4.1 (11/22/2018)

IMPROVED

• Improved the decoding performance for Aztec, increasing the recognition rate.
• Improved the decoding performance for OneD, decreasing the error recognition rate.
• Added further check points for Timeouts, enhancing the timeout control on large scale images for decoding.

FIXED

• Small fixes and tweaks.

6.4 (10/15/2018)

New

• Added a BatchDecode tool which helps developers evaluate the recognition performance and speed of the Dynamsoft Barcode Reader SDK.
• Added a new sample demonstrates how to use Dynamsoft Barcode Reader in multiple threads.

IMPROVED

• Improved barcode reading speed by 10%, especially for small-sized images.
• Reorganized API documentation to help you find content more easily.
• Simplified Developer's Guide to guide you through creating a HelloWorld project more quickly.

FIXED

• Small fixes and tweaks.

6.3 (08/16/2018)

New

• Added the support for Aztec codes.
• New developer's guide (.pdf) to cover common use cases,and re-worked existing PDF content to improve its usability.
• New API documentation (.chm) to help you find content more easily.
• Added GetRuntimeSettings and UpdateRuntimeSettings to help you adjust runtime barcode reading settings.
• Added ResetRuntimeSettings to reset runtime barcode reading settings to default values.
• Added InitRuntimeSettingsWithString and InitRuntimeSettingsWithFile to initialize barcode reading settings at runtime.
• Added OutputSettingsToString and OutputSettingsToFile to review runtime barcode reading settings.
• Added AppendTplStringToRuntimeSettings and AppendTplFileToRuntimeSettings to append a new template string/file to the current runtime settings.

IMPROVED

• Improved the logic for ExpectedBarcodesCount. Previously the barcodes it returned may be greater than the given value of ExpectedBarcodesCount. Now as long as the expected barcodes found, it will stop continue searching and decoding barcodes.

FIXED

• Small fixes and tweaks.

6.2 (06/28/2018)
