Release Notes for C++ Edition - 2.x

2.6.1000 (11/28/2024)

Enhanced document detection delivers more reliable results, particularly for single-document scenarios. Key improvements include:
- Strengthened detection algorithms for greater accuracy and robustness.
- Optimized parameter configurations for better adaptability across diverse scenarios.
- Refined cross-verification rules to ensure more consistent detection outcomes.

Added a new mode, CICM_EDGE_ENHANCEMENT, to the ColourConversionModes parameter, designed to enhance edge details when converting a color image to grayscale.
Introduced the concept of LogicLines to enhance the processing and analysis of document structures.
- Added a new value, IRUT_LOGIC_LINES, to the IntermediateResultUnitType enumeration.
- Added a new function OnLogicLinesReceived to the class CIntermediateResultReceiver which will be called when logic lines have been received.
- Added a new class, CLogicLinesUnit, to represent an intermediate result unit containing logic lines.
Added the GetCrossVerificationStatus function to both the CDetectedQuadResultItem and CNormalizedImageResultItem classes, along with a new CrossVerificationStatus enumeration, to retrieve the cross-verification status of the result.
Added the GetParameterTemplateCount and GetParameterTemplateName functions to the CCaptureVisionRouter class to improve accessibility and usability of templates.
Added the GetFieldRawValue method to the CParsedResultItem class to retrieve the raw value of the field.

Fixed a bug in CTextZone caused by the absence of a custom copy constructor, which led to improper memory management with the default copy constructor.
Fixed a bug where the Default preset template was not used when the default value was passed for the templateName parameter.
Fixed a potential crash bug during template reading.
Fixed a bug in DPM mode where the isMirrored value in the CBarcodeResultItem was not correctly assigned.
Fixed a bug where DotCode could not be decoded in certain scenarios.
Small fixes and tweaks.

Updated the parameter configurations for the DetectDocumentBoundaries_Default and DetectAndNormalizeDocument_Default preset templates to default to single-document mode.
Changed default value of ExpectedDocumentsCount paramter from 0 to 1 to better support single-document mode.
Changed default value of CornerAngleRange paramter from [70, 110] to [60, 120] to support a wider range of document capture angles.
Modified the return logic for DetectedQuadResultItem and NormalizedImageResultItem when ResultCrossVerification is enabled. Previously, only verified results were returned; now, results are returned regardless of verification status, and the results include a CrossVerificationStatus to indicate the verification state.
Removed the LineExtractMode parameter and replaced it with ShortlineDetectionMode and LineAssemblyMode for more flexible and precise configuration.

Added to-the-latest overlapping feature.
Added ARM64 and macOS components back to the SDK.
Improved the error handling logic of methods Capture, StartCapturing and InitLicense to clearly report a licensing issue.

Added new functions SetMaxOverlappingFrames, GetMaxOverlappingFrames, EnableLatestOverlapping and IsLatestOverlappingEnabled to the class CMultiFrameResultCrossFilter.
Added new error codes
- EC_LICENSE_WARNING
- EC_BARCODE_READER_LICENSE_NOT_FOUND
- EC_LABEL_RECOGNIZER_LICENSE_NOT_FOUND
- EC_DOCUMENT_NORMALIZER_LICENSE_NOT_FOUND
- EC_CODE_PARSER_LICENSE_NOT_FOUND

Fixed a crash bug caused by the usage of RegEx.
Fixed a bug that could prevent the reading of GS1_DATABAR_EXPANDED_STACKED barcodes.
Small fixes and tweaks.

Changed the template loading mode. By default, the library loads all template files from the Templates folder in the same directory as the library file.
Changed the enumeration value of BarcodeFormat::BF_ALL to 0xFFFFFFFEFFFFFFFF.

The following submodules are included in this SDK release along with their respective versions:
