• Added a new function GetParsedResult to the CCapturedResult class to get all the result items with the type CRIT_PARSED_RESULT.
• Added new virtual destructors to the following interfaces to prevent memory leaks.
  • CCaptureStateListener
  • CImageSourceStateListener
• Added a new class CCapturedResult which is migrated from the DynamsoftCore library.

Improved

• Security update for DynamsoftCaptureVisionRouter library.
• Supported multiple instances of the class CCaptureVisionRouter.

Changed

• Changed the internal logic of the function SetResultUnitTypesOnlyForInput of ObservationParameters. The function only takes effect when the callback of the specified result unit is implemented.

Fixed

• Fixed a bug where error messages are not output when parsing the parameter templates.

2.2.0 (01/16/2024)

New

• Updated the template system
  • Added StringLengthRange for TextDetectionMode.
  • Added Argument BarcodeFormat for DPMCodeReadingModes. Currently, you can specify “BF_DATAMATRIX” or “BF_QR_CODE” for the parameter.
  • Added ReferenceTaskNameArray under Location.ReferenceObjectFilter to filter the reference objects generated by the task name.
  • Added the support of the OutputTaskSetting definition. The following subparameters are available in OutputTaskSetting object:
    • 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:
  • CIntermediateResultReceiver
  • CapturedResultReceiver
  • CapturedResultFilter
  • CIntermediateResultManager
• Added a new call back method OnShortLinesUnitReceived to the CIntermediateResultReceiver class. The CIntermediateResultReceiver inherited the CAbstractIntermediateResultReceiver.
• Added methods PauseCapturing and ResumeCapturing. Two new CapturedState members, CS_PAUSED and CS_RESUMED, are added as well.
• Added a new property documentSettings to struct SimplifiedCaptureVisionSettings. The corresponding struct SimplifiedDocumentNormalizerSettings is added to the DynamsoftDocumentNormalizer module to store the documentSettings.
• Add C interfaces and implementations, which are only used to encapsulate upper-level languages such as c# and python, etc.

Break Changes

• Changed the logic of the StopCapturing method.
  • CaptureResultReceiver 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 SimplifiedCaptureVisionSettings:
  • If the result item types don’t match the specified template, the method UpdateSettings will return the error code EC_PARAMETER_VALUE_INVALID 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 CRIT_BARCODE, CRIT_TEXT_LINE, CRIT_DETECTED_QUAD, CRIT_NORMALIZED_IMAGE. Otherwise, the method UpdateSettings will return the error code EC_PARAMETER_VALUE_INVALID with the message “The captured result item types should contain at least one task result type”.
• Change the compiler option of the runtime library of Windows DLLs from MD to MT.

2.0.30 (02/01/2024)

New

• Added internal APIs to obtain resources based on the specified template.

2.0.20 (10/26/2023)

New

• Added the following preset templates:
  • PT_READ_BARCODES_SPEED_FIRST;
  • PT_READ_BARCODES_READ_RATE_FIRST;
  • PT_READ_BARCODES_BALANCED;
  • PT_READ_SINGLE_BARCODE;
  • PT_READ_DENSE_BARCODES;
  • PT_READ_DISTANT__BARCODES;
  • PT_RECOGNIZE_NUMBERS;
  • PT_RECOGNIZE_LETTERS;
  • PT_RECOGNIZE_NUMBERS_AND_LETTERS;
  • PT_RECOGNIZE_NUMBERS_AND_UPPERCASE_LETTERS;
  • PT_RECOGNIZE_UPPERCASE_LETTERS;
• Added parameter Page to ImageSource object.
• Added a new parameter minImageCaptureInterval which can be set via the struct SimplifiedCaptureVisionSettings or the CaptureVisionTemplate object of a JSON template file.
• Added “UNKNOWN” as a supported value of the TextDetectionMode.Direction parameter. Changed the default value of Direction to “UNKNOWN”.

Improved

• Optimize the logic to support calling IntermediateResultManager.addResultReceiver and IntermediateResultManager.removeResultReceiver after StartCapturing.
• Added ability to output all templates via methods outputSettings and outputSettingsToFile by specifying “*” for the parameter templateName.

Fixed

• Small fixes and tweaks.

2.0.10 (08/08/2023)

Improved

• Improved the implementation of the StopCapturing method to prevent deadlock when invoked in the management thread.
