7.3.0-v2 (7.3.0.2) (02/14/2020)

IMPROVED

Improved the process to release a camera in use. This makes it easier to destroy a Barcode Scanner instance in a component (Angular, Vue, React, etc.)

FIXED

Fixed the bug on iOS 12 where 1D barcode can’t be read by a Barcode Scanner instance when the default “speed” template is used by fixing the localization mode “LM_CONNECTED_BLOCKS” and restoring it as the default mode.

7.3.0-v1 (7.3.0.1) (01/20/2020)

FIXED

Fixed a bug on iOS 12 where 1D barcode can’t be read by a Barcode Scanner instance when the default “speed” template is used by changing the default localization mode from “LM_CONNECTED_BLOCKS” to “LM_SCAN_DIRECTLY”. “LM_CONNECTED_BLOCKS” is the mode with the bug.

7.3.0 (01/14/2020)

NEW

Added a new barcode type Postal codes including USPS Intelligent Mail, Postnet, Planet, Australia Post barcode, RM4SCC. Added a new localization mode LM_STATISTICS_POSTAL_CODE in the struct PublicRuntimeSettings -> LocalizationModes to recognize Postal codes.
Implemented the feature of recognizing distorted QR barcode. It can be enabled by turning on the struct PublicRuntimeSettings -> FurtherModes -> DeformationResistingModes.
Implemented the feature of complementing missing parts of QR Code & DataMatrix barcodes. It can be enabled by turning on the struct PublicRuntimeSettings -> FurtherModes -> BarcodeComplementModes.
Added a new setting ScaleUpModes to set the scale-up mode for linear barcodes with small module size. It can be enabled by turning on the struct PublicRuntimeSettings -> ScaleUpModes.
Added a new API Dynamsoft.BarcodeReader.detectEnvironment() that returns information like the OS type, browser type, WASM support, camera support, etc.
Added an instance property singleFrameMode, which when enabled, allows the user to open a UI to snap a single frame from the camera instead of showing its video stream in the browser for barcode reading.
Added two new APIs pauseScan() and resumeScan() to better handle the scanning process while showing the video stream.
Built-in several customizable UI elements and instruction sounds so that users can easily distinguish the following
Whether the BarcodeScanner instance is scanning
Which region the BarcodeScanner instance is scanning
Where the found barcode symbols are

IMPROVED

Improved the decoding accuracy for DataMatrix that has a narrow quiet zone.
Improved the decoding accuracy for 1D barcode that has a small module size.
Improved the logic for camera selecting so that a better camera may be selected by default in the case of having multiple cameras available.
Improved the method updateRuntimeSettings so that it accepts three default profiles namely “speed”, “coverage” & “balance” thus making it easier to use. Note that “speed” is the default profile for each BarcodeScanner instance and “coverage” for each BarcodeReader instance.

7.2.2 (11/27/2019)

NEW

Added frame filtering feature so that out-of-focus frames are discarded during the scanning operation.

IMPROVED

Updated algorithm to 7.2.2.
Improved the accuracy for OneD barcode decoding.
Two WASMs are provided for deployment
1. Compact WASM: Default. Smaller but only supports OneD, PDF417, QR and DataMatrix codes.
2. Full WASM: Bigger but has all features.

7.1.0 (08/29/2019)

IMPROVED

Updated algorithm to 7.1.
Improved the speed to download, build and initialize the library
Improved the readability of barcode result text by using UTF-8 encoding
Improved developer’s guide to be clearer and more precise
Renamed setScanSettings for updateScanSettings for naming consistence.

7.0.0 (08/09/2019)

NEW

Added the capability to enable/disable the torch/flashlight of a mobile device (when available, only Chrome on Android).
Added APIs for finer video control. These APIs are getAllCameras, getCurrentCamera, setCurrentCamera, getResolution, setResolution.

IMPROVED

Updated algorithm to 7.0.
Updated default runtimeSettings for BarcodeScanner.
Improved 1D barcode decoding accuracy by comparing results from multiple frames.
Improved the namespace and overall structure of the APIs while maintaining backward compliance.

FIXED

Small fixes and tweaks.

6.5.2 (06/12/2019)

NEW

Added compatibility for CSP (Content Security Policy).
Added samples for Vue, React and Angular.

IMPROVED

Optimized 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, resulting in a higher chance to successfully confirm a 1D barcode result whose confidence is not extremely high.
Reduced the possibility of conflicts with neighbour barcodes, improving the precision of the zone to be deleted when a barcode is recognized successfully.
Super large-size (4096x4096 pixels) images can be processed and decoded. The license key can be written in the script label.

FIXED

Enhanced the robustness of the image processing algorithm. This resolved segmentation faults when a 0-size image is passed to our SDK or when there are a few small barcode zones which require spatial transformation.
Small fixes and tweaks.

6.5.1 (04/28/2019)

NEW

Added d.ts file to support typescript.
Added the UMS/ESM export for Node.js.
Added a built-in scanner construct to support video settings.

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

Decreased error recognition rate for Aztec Codes.

FIXED

Small fixes and tweaks.

6.4.1 (12/11/2018)

IMPROVED

Fast loading and initialization and support of Web Worker to ensure seamless and smooth barcode scanning instantly.
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.

6.3.0 (08/16/2018)

NEW

New JavaScript Preview Edition - a JavaScript API for barcode scanning based on the WebAssembly technology - is now available.

5.2.0 (09/18/2017)

IMPROVED

Optimized the de-blur algorithm for 1D barcodes to improve the recognition accuracy.
Optimized the timeout support. Now it is possible to stop barcode recognition by timeout.

FIXED

Small fixes and tweaks.

5.1.0 (05/25/2017)

NEW

Added the JavaScript Edition to support reading barcodes in JavaScript on the client side. It used to act as an add-on to our browser-based document scanning SDK - Dynamic Web TWAIN. It is now a separate edition, which enables you to seamlessly embed barcode reading functionality with Dynamic Web TWAIN for online document scanning and Dynamsoft Camera SDK for webcam capture in your application.

FIXED

Small fixes and tweaks.
