Release Notes - JavaScript 2.x

2.2.31 (08/07/2023)

Fixed an issue where TypeScript 5 cannot locate the declaration file when importing package.
Fixed a regular expression error in the MRZ template that could lead to misrecognition.

Added option captureAndRecognizeInParallel to the interface ScanSettings to control whether to speed up the recognition by capturing the next frame in advance.

The method setImageSource() now takes an additional parameter options which helps to pass the information needed by the LabelRecognizer object, such as the definition (Dynamsoft.DCE.DrawingItem) for creating the shapes that highlight barcodes.
The method pauseScanning() now accepts an optional parameter options, which can control the behavior of the pause, such as whether to keep results highlighted (keepResultsHighlighted).
This version uses Dynamsoft Camera Enhancer version 3.0.1.

Fix a bug with VIN result verification, which may lead to errors when the VIN code start and end with the character “1”.

Added event onVINRead. This event is used when the SDK is configured with the template “VIN” or “video-VIN” in which case extra processing is applied for better recognition of VIN codes.

Reduced the size of MRZ model from 10MB to 2.56MB. This significantly reduces the time for the initialization of the SDK for MRZ recognition.
Improved single-line text confidence. This enables users to perform confidence filtering on the generated results to improve recognition accuracy.
Improved character segmentation when dealing with some connected characters. This improves the recognition accuracy.

Added method setImageSource() to specify an Image Source which provides images of the type DSImage for continuous scanning.

Improved the built-in sound which is played when recognition succeeds. Check out more on whenToPlaySoundforSuccessfulRead and soundOnSuccessfullRead.

Renamed event onFrameRead to onImageRead.
Moved the following properties to ScanSettings.
- whenToPlaySoundforSuccessfulRead
- soundOnSuccessfullRead
- whenToVibrateforSuccessfulRead
- vibrateDuration

Removed property singeleFrameMode which should be taken care of by a CameraEnhancer instance.

Removed the following UI related APIs, use the bound CameraEnhancer instance to manipulate UI instead.
- getUIElement()
- setUIElement()
- defaultUIElementURL
- highlightFillStyle
- highlightStrokeStyle

- regionMaskLineWidth

Added event onResourcesLoadProgress which is triggered multiple times when the resource file for a particular template is beling loaded.

Added a new template MRZ for recognizing Passports, Visas and IDs with Machine-readable zones.
Added property isCheckDigitMatched to the interface DLRLineResult.
Added events onResourcesLoadStarted / onResourcesLoaded which gets triggered when the resource file for a particular template starts to be loaded / finishes loading.
Added method updateReferenceRegionFromBarcodeResults to make it possible for a DLR instance to use the results of DLR as the reference region.

Renamed the template visaMRZ_A to visaMRZ and updated it to support both Format-A machine readable visas (MRV-A) and Format-B machine readable visas (MRV-B).
Improved the method recognize() to support DCEFrame objects.

Supports decoding of various formats of source data.
Integrated with Dynamsoft Camera Enhancer v2.0.3 to support continuous label scanning of frames from a video input.
Supports various use cases with multiple built-in templates.
