    • OutputCondition
    • TaskResultArray
    • TargetROIDefName
    • TaskSettingNameArray
    • BackwardReferenceOutput
    • ReferenceTaskNameArray
    • ReferenceResultTypeArray
    • Operator
  • Updated TextLineSpecification to support text line group definition. Added the following subparameters:
    • OutputResults
    • ConcatResults
    • ConcatSeparator
    • ConcatStringLengthRange
    • ConcatStringRegExPattern
    • ReferenceGroupName
    • TextLinesCount
    • SubGroups
  • Offset parameter is optimized.
    • Added ReferenceObjectType to specify whether the reference object is an atomic object or the whole image.
    • Added ReferenceXAxis & ReferenceYAxis to define the X & Y axis.
    • Modified FirstPoint, SecondPoint, ThirdPoint & FourthPoint. You can specify whether the X or Y coordinate of the point is measured by percentage.
    • Deprecated ReferenceObjectSize Type.
• The following classes are migrated from DynamsoftCore module:
  • DSCapturedResult
  • DSIntermediateResultReceiver
  • DSCapturedResultReceiver
  • DSCapturedResultFilter
  • DSIntermediateResultManager
• Added a new call back method onShortLinesUnitReceived to the DSIntermediateResultReceiver class.
• Added methods pauseCapturing and resumeCapturing. Two new enumeration members, CapturedStatePaused and CapturedStateResumed, are added to DSCapturedState as well.
• Added a new property documentSettings to class DSSimplifiedCaptureVisionSettings. The corresponding class DSSimplifiedDocumentNormalizerSettings is added to the DynamsoftDocumentNormalizer module to store the documentSettings.

Breaking Changes

• Changed the logic of the stopCapturing method.
  • DSCaptureResultReceiver will not receive results after stopCapturing is triggered with waitForRemainingTasks false.
  • Support stop capturing after the pauseCapturing method is triggered.
• Changed the logic of the capturedResultItemTypes setting of DSSimplifiedCaptureVisionSettings:
  • If the result item types don’t match the specified template, the method updateSettings will return the error code DSErrorParameterValueInvalid with the message “The captured result item types do not match the task configurations in the template”.
  • Based on the capturedResultItemTypes setting, the irrelevant tasks will be removed from the template.
  • The capturedResultItemTypes should include at least one of the DSCapturedResultItemTypeBarcode, DSCapturedResultItemTypeTextLine, DSCapturedResultItemTypeDetectedQuad, DSCapturedResultItemTypeNormalizedImage. Otherwise, the method updateSettings will return the error code DSErrorParameterValueInvalid with the message “The captured result item types should contain at least one task result type”.
