Change Log

2.5.1 (2018-07-02)

• Fixed a bug that caused the library to fail when showing video output in some browsers.
• Updated external Scandit Engine library with a fix for a rare QR code bug.

2.5.0 (2018-06-29)

• Added a new BarcodePicker.setCameraSwitcherEnabled() function to dynamically show or hide the GUI button to switch between different cameras, plus a relative BarcodePicker.isCameraSwitcherEnabled() function to get the current status.
• Added a new BarcodePicker.setTorchToggleEnabled() function to dynamically show or hide a GUI button to toggle device torch on/off, plus a relative BarcodePicker.isTorchToggleEnabled() function to get the current status.
• Added a new BarcodePicker.setTapToFocusEnabled() function to dynamically enable or disable manual camera focus when clicking/tapping on the video, plus a relative BarcodePicker.isTapToFocusEnabled() function to get the current status.
• Added a new BarcodePicker.setPinchToZoomEnabled() function to dynamically enable or disable camera zoom control via pinching gesture on the video, plus a relative BarcodePicker.isPinchToZoomEnabled() function to get the current status.
• Added a new BarcodePicker.getScanner() function to retrieve the initialized (and possibly configured) Scanner object internally used by the BarcodePicker instance.
• Added a new scanner option to BarcodePicker.create() to pass and use an already initialized (and possibly configured) Scanner object on creation. Using this when needed can lead to faster component initalization thanks to the reuse of the already available external Scandit Engine library in the object.
• Added a new destroyScanner argument (enabled by default) to the BarcodePicker.destroy() function, allowing to prevent Scanner destruction on BarcodePicker destruction.
• Changed BarcodePicker.setActiveCamera()'s camera argument to be optional: when not provided the default camera is selected.
• Fixed BarcodePicker.pauseScanning() not pausing camera input if the relative argument is passed and the BarcodePicker is already in a paused state.
• Fixed BarcodePicker.accessCamera() not re-accessing the camera when camera access was previously paused via BarcodePicker.pauseScanning().
• Improved error reporting when getting/setting symbology settings for invalid symbologies.
• Updated external Scandit Engine library to version 5.8.0.
• Documented new Samsung Internet Browser 7+ support

2.4.5 (2018-06-13)

• Fixed an important bug causing the external Scandit Engine library to regularly block while making network requests on startup and regularly after scanning a barcode, this is now correctly handled in the background. Now startup times are slightly faster, online status is not required after library initialization and subsequent scans of barcodes are smoother and without interruptions (network conditions don't affect all these scenarios anymore).

2.4.4 (2018-06-05)

• Correctly throw UnsupportedBrowserError in case one of the WebAssembly-bugged iOS versions is used (11.2.2/11.2.5/11.2.6).
• Show alerts about internal engine errors by default only when running on a local IP address (still always logged to console).
• Updated adapter library to version 6.2.1.
• Updated howler library to version 2.0.12.
• Updated tslib library to version 1.9.2.

2.4.3 (2018-05-31)

• Removed automatic WebView classification as unsupported in Android, as actual support might work depending on the containing app.

2.4.2 (2018-05-22)

• Updated external Scandit Engine library to version 5.8-beta.2.
• Further optimized WebAssembly code size.
• Improved general frame processing speed.

2.4.1 (2018-04-27)

• Updated external Scandit Engine library to version 5.7.2.
• Fixed incorrect behaviour of some browsers causing an error when trying to load cached compiled WebAssembly code.

2.4.0 (2018-04-25)

• Implemented caching of compiled WebAssembly code on browsers that support this (currently only Firefox), this makes subsequent loads of the library much faster and don't require re-downloading WebAssembly files.
• Improved detection of missing browser / OS functionality in WebView scenarios on Android devices.
• Implemented functionality to retrieve image data information whenever a frame is processed by a BarcodePicker.
• Added a new imageData property to the ScanResult object, containing the raw image byte data of the processed frame.
• Added a new imageSettings property to the ScanResult object, containing the image settings used to parse the image data of the processed frame.
• Added a new BarcodePicker.onProcessFrame() function to register a listener to get a ScanResult at every frame that is processed, independently from the number of recognized barcodes.
• Added new BarcodePicker.removeProcessFrameListener() and BarcodePicker.removeProcessFrameListeners() functions to remove the new "processFrame" listeners.
• Updated adapter library to version 6.1.5.
• Improved CHANGELOG format.

2.3.0 (2018-04-12)

• Fixed and improved camera enumeration and selection in Firefox.
• Fixed incorrect video feed display in some situations in Edge.
• Improved localization and scanning performance of challenging 1D codes in the center of the video frame.
• Fixed incorrect application of scanning search area settings in some edge cases.
• Implemented object fit options for BarcodePicker objects, to set the video feed to "cover" or "contain" and thus be resized differently inside the given origin element.
• Added a new videoFit option to BarcodePicker.create() to set video element fit type on creation.
• Added a new BarcodePicker.setVideoFit() function to set fit type dynamically for the video element.
• Added a new BarcodePicker.ObjectFit enum to list the different types of object fit types available.
• Deprecated BarcodePicker.GUIStyle numerical enumeration values in favor of string values for optional easier JavaScript usage (ex. BarcodePicker.GUIStyle.LASER is now "laser" instead of 1).
• Deprecated Camera.Type numerical enumeration values in favor of string values for optional easier JavaScript usage (ex. Camera.Type.FRONT is now "front" instead of 0).

2.2.1 (2018-04-04)

• Fixed failing camera video feed recovery after unexpected camera identifier changes in Safari.

2.2.0 (2018-03-28)

• Implemented scanning speed throttling functionality to allow tradeoffs between scan performance and power usage.
• Added a new targetScanningFPS option to BarcodePicker.create to set target frames per seconds to be processed/scanned.
• Added a new BarcodePicker.setTargetScanningFPS() function to set target frames per seconds to be processed/scanned.

• Added a new enablePinchToZoom option to BarcodePicker.create() to enable/disable pinch-to-zoom (when available).

• Fixed tap-to-focus functionality failing to work on some devices.

2.0.0 (2018-03-15)

• Updated external Scandit Engine library to version 5.7-beta.1.
• Added functionalities for easier/better usage of single-instance background BarcodePickers that don't acccess cameras all the time and are shared for different elements.
• Added a new pauseCamera option to BarcodePicker.pauseScanning() to also pause camera input, allowing to interrupt (and later resume) the current camera stream.
• Added a new BarcodePicker.reassignOriginElement() function to re-assign the BarcodePicker to a different HTML element.
• Breaking change: BarcodePicker.resumeScanning() function now returns a promise resolving to the object instance instead of directly to the instance; this is due to the fact that the method might need to access the camera again.
• Removed deprecated BarcodePicker.UIStyle enum.
• Removed deprecated BarcodePicker.UIStyle.SCANLINE enum value.
• Removed deprecated BarcodePicker.create()'s uiStyle option.
• Updated adapter library to version 6.1.4.
