Release Notes for Python SDK - 9.x

9.2.0 (06/21/2022)

Barcode boundary-seeking algorithm is refactored to improve stability.
Pharmacode decoding is optimized to improve accuracy.
The function of device-alias is added to allow users to give each device a readable name. For end-users and administrators, this makes it more friendly to distinguish between devices about license usage statistics.

Added a new method set_device_friendly_name to set a human-readable name that identifies the device.

Simplified the license activation steps. Different license activation APIs are integrated into initLicense method.
Added support for Pharmacode.
Added support for Code 11, a 1D format.
Deformation resisting modes DRM_BROAD_WARP, DRM_LOCAL_REFERENCE and DRM_DEWRINKLE are optimized and detached from DRM_GENERAL. Users can specify a more effective deformation resisting mode when processing QRCode and DataMatrix codes.
Optimized the confidence scoring system for PDF417 codes.

Added BF_CODE_11 under Enumeration EnumBarcodeFormat to specify newly supported barcode format, Code 11.
Added BF2_PHARMACODE_ONE_TRACK, BF2_PHARMACODE_TWO_TRACK and BF2_PHARMACODE under Enumeration EnumBarcodeFormat_2 to specify newly supported barcode format, Pharmacode.
Added error code DBRERR_PHARMACODE_LICENSE_INVALID which will be returned when the license of Pharmacode is invalid.
Added DRM_BROAD_WARP, DRM_LOCAL_REFERENCE and DRM_DEWRINKLE under Enumeration EnumDeformationResistingMode to apply new deformation resisting modes.
Added a parameter FormatSpecification.PartitionModes
Added a parameter FormatSpecification.VerifyCheckDigit
Added an Argument ConfidenceThreshold to the LocalizationModes mode arguments.

Changed method init_license to a static method.
Changed value of BF_ONED under Enumeration EnumBarcodeFormat to 0x003007FF to have BF_CODE_11 combined.
Changed value of BF_ALL under Enumeration EnumBarcodeFormat to 0xFE3FFFFF to have BF_CODE_11 combined.
Changed the behaviour of DeformationResistingMode DRM_GENERAL which now only applies basic process to resist deformation.
Changed the return value of the method get_idle_instances_count from 0 to -1 when the available count needs to be updated from server by calling init_license.

Fixed a bug that might cause a crash when using multiple threads for barcode decoding.
Fixed a bug that throws exceptions when using method get_idle_instances_count.
Fixed a bug that Function Code 1 (FNC1) character would not return if it was in the first position of GS1-128 codes.
Other small fixes and tweaks.

The following items are now deprecated. They still work in this version but could be removed in the near future.
