- Fixed a bug where it takes more time than expected when creating a
- Fixed a bug which makes the building fail in frameworks such as Angular, React, Vue, etc.
- Added a new localization mode
ONED_FAST_SCAN, which significantly improved the localization speed for 1D barcodes.
- Added the ability to specify barcode
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.
- Reading speed has significantly increased based on better camera control and optimized memory usage in the core algorithm.
- Misreading of 2D barcodes has been significantly reduced as a result of better result filtering based on the optimized algorithm in reading confidence calculating.
- Refactored camera related APIs internally for easier maintenance.
- Improved result filtering so that misread 2D barcodes are not returned.
The class names of the built-in UI elements have changed
Fixed an issue where the scanning page may freeze when debugging in the Developer Tools with Chromium-94 browsers on PCs.
Fixed a bug where an error occurs when switching region setting from a JSON object to an array of objects.
- 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
- Continuous reading of barcodes from a video input is now significantly faster thanks to optimized frame fetching logic.
- Camera selecting on devices with multiple cameras has been optimized so that the main camera is always used by default. This is especially helpful on high-end Android devices.
- Misreading of 1D barcodes has been significantly reduced as a result of better result filtering based on the optimized algorithm in reading confidence calculating.
- Improved frame fetching so that more frames are read for the same time period.
- Improved camera selecting so that the initial camera used is the main camera.
- Improved result filtering so that misread 1D barcodes are not returned.
- Improved WebGL implementation so that much less time is required for image preprocessing.
- Added method isWasmLoaded() to return whether the engine file is loaded.
- Added method isContextDestroyed() to return whether a BarcodeReader or BarcodeScanner instance has been destroyed.
- Added method getOriginalImageInACanvas() to return the actual image the engine tried to read barcodes from.
- Added method destroyContext() to destroy the BarcodeReader or BarcodeScanner instance itself.
- Added property ifSaveOriginalImageInACanvas to control whether the actual image to read is saved for debugging.
- Added property whenToPlaySoundforSuccessfulRead to control when the beep sound should be played.
- Added property whenToVibrateforSuccessfulRead to control when the device should vibrate.
- Change the default engine from the compact engine to the full-featured engine.
- The method destroy() is deprecated, Use the method destroyContext() instead.
- The property isLoaded is deprecated. Use the method isWasmLoaded() instead.
- The property bDestroyed is deprecated. Use the method isContextDestroyed() instead.
- The property oriCanvas is deprecated. Use the method getOriginalImageInACanvas() instead.
- The property bVibrateOnSuccessfulRead is deprecated. Use whenToVibrateforSuccessfulRead instead.
- The property bPlaySoundOnSuccessfulRead is deprecated. Use whenToPlaySoundforSuccessfulRead instead.
- The property bSaveOriCanvas is deprecated. Use ifSaveOriginalImageInACanvas instead.
- Added a new argument,
ThresholdCompensation, to the
BinarizationModes mode arguments.
- Improved the speed of identifying 1D codes from still images.
- Improved the speed of identifying dense QR codes.
- Improved the performance of boundary identification for DataMatrix codes.
- Improved camera selection in some browsers on Android devices.
- Improved the
createInstance() method to avoid unnecessary download of the file “dbr.scanner.html”.
- Moved the following APIs from
Please note that these APIs still exist under
Dynamsoft. DBR. BarcodeReader , but they have been deprecated and replaced by APIs in the new namespace.
- Added property
organizationID which can be used to fetch license(s) belonging to the specified organization from the License Tracking Server.
- Added a class name to the powered-by message element on the built-in UI so that it can be manipulated in CSS.
- Removed redundant warning messages for duplicate barcodes.
- Fixed a bug with the API
bSaveOriCanvas where the same canvas is reused resulting in duplicated original image for different barcodes.
- Added properties
vibrateDuration to control the vibration of a device when barcodes are found.
- Added methods
decodeCurrentFrame() to make it possible for users to show the video and manually trigger the decoding of a frame.
- Added a sample for Vue 3.
- Optimized how the WASM files are created to make them smaller (18% smaller).
- When opening a camera takes too long and times out, an exception will be thrown.
- When the webpage in which a
BarcodeScanner instance is running gets hidden (not visible to the user), the barcode scanning will stop automatically. Later when it becomes visible again, the scanning will resume automatically.
- Added a “Powered by Dynamsoft” logo to the default Barcode Scanner UI.
- Resolved a bug that returns the error as a Promise object instead of a string when calling the method loadWasm().
- Added a new mode argument,
RegionPredetectionModes that determines if the SDK attempts to find an accurate boundary when RegionPredetectionModes is set to
- Improved both the localization and decoding algorithms for Postal Codes.
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.
- Added support for SSR (Server-side Rendering) and 3 related samples for Nextjs, Nuxtjs and gatsby respectively.

scanner.destroy() is called before
scanner.show() finishes, the camera will not be released.
parityData in the
