Scandit Data Capture SDK 6.8 Release Notes (June 3, 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.Create().
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 while in On or Standby state.
Fixed a bug that would cause TrackedBarcode.Barcode to have an outdated position.
MRTD parser: Fixed an issue where the name field could have numeric characters.
MRTD parser: Fixed an issue with parsing some Belgian TD1 documents.
DLID parser: Fixed issues with parsing day of expiration date for a magstripe format.
GS1 AI parser: Fixed an issue causing some human-readable GS1 codes to not be parsed.
Fixed a memory leak when using a TorchSwitchControl with the DataCaptureView being invisible.
Fixed a crash 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.
Deprecations
Deprecated SpotlightViewfinder. Use RectangularViewfinder with one of the new styles (Rounded or Square) and non-zero Dimming instead.
Deprecated constructors for Sound in favour of AssetSound and ResourceSound. They will be removed in the next major release.
Updates
Scandit Data Capture SDK 6.8.1 Bug Fixes (June 18, 2021)
Fixed a memory leak when repeatedly recreating the DataCaptureView.
Fixed a rare crash that could be triggered if the camera experienced an error while running.
