Scandit Data Capture SDK 6.3 Release Notes (May 12th 2020)

See also the System Requirements of the Scandit Data Capture SDK across all platforms.

New Features

• Added SDCSymbologyIATATwoOfFive.

• Code 128 now always uses relaxed quiet zone rules. It is no longer necessary to use the relaxed quiet zone symbology extension.

• Added SDCImageFrameSource. This new type of SDCFrameSource allows to capture data inside UIImages (for example scanning barcodes in a UIImage).

• Introduced an experimental torch state (SDCTorchStateAuto) that turns the torch on or off based on the current illumination.

• Added SDCTorchListener - a delegate to be invoked when SDCTorchState of a SDCCamera changes.

• The ScanditLabelCapture framework (containing SDCLabelCapture) no longer requires ScanditTextCapture (containing SDCTextCapture) as a dependency if the label to be recognized does not require any text recognition.

• Added SDCRectangularViewfinder.disabledColor to set color of the viewfinder when the mode is disabled.

• When the shouldShowScanAreaGuides option is enabled point of interest is always drawn. When the radius for radius location selection is set to 0 then a small circle is drawn.

• Added SDCDataCaptureContext.deviceID to get the unique identifier of the device.

• Added SDCFeedback deserialization (feedbackFromJSONString:error:).

• Added SDCBarcodeTrackingAdvancedOverlay deserialization (barcodeTrackingAdvancedOverlayFromJSONString:mode:error: and updateFromJSONString:error:).

• Added SDCTextCapture deserialization (SDCTextCapture.textCaptureFromJSONString:context:error: and SDCTextCapture.updateFromJSONString:error:) and SDCTextCaptureSettings updating through deserialization (SDCTextCaptureSettings.updateFromJSONString:error:).

• Added SDCTextCaptureFeedback deserialization (SDCTextCaptureFeedback.textCaptureFeedbackFromJSONString:error:).

• Added SDCParser deserialization (SDCParser.parserFromJSONString:context:error: and SDCParser.updateFromJSONString:error:).

• DLID parser: Added the “issuer” field, its value is the ISO code of the issuing state.

• SwissQr parser: minimalVersion option added to the parser. The default minimal version of SwissQr codes that are parsed was changed to 2.0.

• MRTD parser: allowFalsePositiveCompensation option added.

• US Uniformed Services ID (UsUsid) parser support for PDF417 barcodes.

Behavioral Changes

No behavioral changes have been made.

Performance Improvements

• Improved recognition for 1d barcodes close to 1px per bar.

Bug Fixes

• Fixed a very rare infinite loop in the QR code reader.

• Fixed an unhandled intersection error in the Data Matrix Decoder.

• Fixed a bug causing the scan area to be miscalculated in certain scenarios.

• SDCBarcodeTrackingSettings.settingsForSymbology: now returns a nonnull SDCSymbologySettings instance.

• SwissQr parser: fixed bug where additional, empty sections were treated as an error.

Deprecations

No deprecations have been made.
