Changelogs

New

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 IntermediateResultReceiver which will be called when logic lines have been received.
- Added a new class, LogicLinesUnit, to represent an intermediate result unit containing logic lines.
Added the getCrossVerificationStatus function to both the DetectedQuadResultItem and NormalizedImageResultItem classes, along with a new EnumCrossVerificationStatus enumeration, to retrieve the cross-verification status of the result.
Added the getParameterTemplateCount and getParameterTemplateName functions to the CaptureVisionRouter class to improve accessibility and usability of templates.
Added the getFieldRawValue method to the ParsedResultItem class to retrieve the raw value of the field.

Fixed

Fixed a bug in TextZone 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 BarcodeResultItem was not correctly assigned.
Fixed a bug where DotCode could not be decoded in certain scenarios.
Small fixes and tweaks.

Changed

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.

2.2.3000 (08/21/2024)

Highlights

Added confusable character distinguishing: this feature enhances the library’s ability to distinguish between common confusable character sets including {0, o, O}, {1, I, l}, and {5, s, S}, across popular fonts like Arial, Times New Roman, and Verdana, etc.
Supported confusable character set customization: leveraging the new caching mechanism in the CaptureVisionRouter (CVR) module, the library now enables users to customize confusable character sets to meet the needs of specific scenarios.
Introduced the capability for users to influence the image processing process by altering intermediate results. Users can now clone, edit, and substitute intermediate result units within the callback method of each type. Subsequent operations will then proceed based on the updated unit.
Introduced a feature for multi-condition filtering across products. Users can now specify filtering criteria for the task results of a TargetROIDef by implementing an OutputTaskSetting based on the task results of varying products from descendant TargetROIDef objects.
Enhanced the Offset parameter in TargetROIDef. Users now have the capability to meticulously customize components of the coordinate system, including the origin, X-axis, and Y-axis, for precise offset calculation.
Introduced a feature for grouping text lines. A text line group consists of spatially adjacent lines of text. Through the TextLineSpecification parameters, users can now do two things:
- Put text lines in groups and also define the spatial relationship between different groups;
- Specify whether to concatenate text line results within a group, how to do the concatenation and whether to output the concatenated result.
