Scandit Data Capture SDK 6.8 Release Notes (June 3rd 2021)

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

New Features

• Added support for Data Matrix Rectangular Extension (ISO/IEC21471:2020).

• Added blurry barcode reader support for Codabar, increasing the decode range by up to 60% (may vary by device).

• Added “strict” symbology extension for 1d symbologies. It enforces strict standard adherence to eliminate false positives in blurry, irregular or damaged barcodes at the cost of reduced scan performance. See also Symbology Properties.

• Added ECI (Extended Channel Interpretation) support for DataMatrix codes.

• Added ECI (Extended Channel Interpretation) support for Aztec codes.

• Added GS1 support for Aztec codes.

• RectangularViewfinder can now be instantiated with a RectangularViewfinderStyle to customize the style of the viewfinder. The new viewfinder styles can be further customized through lineStyle, animation and dimming.

• LaserlineViewfinder can now be instantiated with a LaserlineViewfinderStyle to customize the style of the viewfinder.

• Added DataCaptureView.logoStyle to customize the style of the logo shown if no viewfinder is already drawing the logo.

• Added RectangularViewfinder.setShorterDimensionAndAspectRatio() which is used as the default sizing for the new styles of the RectangularViewfinder.RectangularViewfinder().

• Added CameraSettings.shouldPreferSmoothAutoFocus property.

• Added TorchSwitchControl to allow toggling the torch on and off non-programmatically. You can add this control to a view by calling DataCaptureView.addControl() and remove it with DataCaptureView.removeControl().

• Added support for null-safety.

Performance Improvements

• Improved 1d barcode scanning performance for codes with perspective distortion.

• Improved decoding performance of large Data Matrix codes.

• Improved 1d barcode reader decode range on the iPhone 12, iPhone 12 Mini and iPhone 12 Pro.

Bug Fixes

• Corrected encoding names to true IANA names, i.e. from “ASCII” to “US-ASCII”, from “ISO8859-x” to “ISO-5589-x” and from “UTF8” to “UTF-8”. Note that this change might break existing code. Please update your code in case it relies on these corrected encoding names.

• Corrected reported encoding for QR codes to “ISO-8859-1” if not explicitly specified otherwise. Previous to this release, when the character encoding is not explicitly specified, the QR code reader would attempt to guess the encoding. This behaviour goes counter to what’s written in the QR code specification. The new default is to assume an encoding of ISO-8859-1 (latin-1).

• Corrected reported encoding for (Micro-)PDF417 codes to “ISO-8859-1” if not explicitly specified with ECI. Previous to this release, in some cases “US-ASCII” was returned.

• Fixed a rare bug that caused PDF417 codes that are part of a Composite Code to be highlighted twice.

• Fixed a bug of routing code length in the USPS intelligent mail symbology. With this release leading zeros are newly included in routing data.

• Fixed camera resolution not being updated on Android while in on or standby state.

• Fixed a bug that would cause TrackedBarcode.barcode to have an outdated position.

• Fixed a crash on Android that could be triggered on certain devices when deallocating the data capture view.

API Changes

• SymbologyDescription.forIdentifier() now returns a nullable SymbologyDescription. Previously it would crash for invalid identifiers.

Updates

Scandit Data Capture SDK 6.8.1 Bug Fixes (June 18th 2021)

• Fixed a memory leak on Android when repeatedly recreating the DataCaptureView.

• Fixed a rare crash on Android that could be triggered if the camera experienced an error while running.
