This method performs recognition and page synthesis of the specified pages in the document.

​
Syntax

​
C++

HRESULT RecognizePages(
  IIntsCollection*          PageIndices,
  ISynthesisParamsForPage*  SynthesisParamsForPage,
  IObjectsExtractionParams* ExtractionParams
);

​
C#

void RecognizePages(
  IIntsCollection          PageIndices,
  ISynthesisParamsForPage  SynthesisParamsForPage,
  IObjectsExtractionParams extractionParams
);

​
Visual Basic .NET

Sub RecognizePages( _
  PageIndices As IIntsCollection, _
  [SynthesisParamsForPage As ISynthesisParamsForPage = Nothing], _
  [ExtractionParams As IObjectsExtractionParams = Nothing] _
)

​
Parameters

PageIndices [in] This parameter refers to the IntsCollection object that contains the numbers of pages to be recognized. SynthesisParamsForPage [in] The SynthesisParamsForPage object that stores parameters of page synthesis. This parameter may be 0. In this case, the page is synthesized with default parameters, or, if a profile has been loaded, the parameters set by this profile are used. ExtractionParams [in] The ObjectsExtractionParams object that stores parameters of objects extraction. This parameter may be 0. In this case, the objects are extracted with default parameters, or, if a profile has been loaded, the parameters set by this profile are used.

​
Return values

If recognition is interrupted by the user, this method will return E_ABORT. It also returns the standard return codes of ABBYY FineReader Engine functions.

​
Remarks

  • This method may report events to the listeners attached to the IConnectionPointContainer interface of the FRDocument object.
  • In Linux and Windows: Depending on the value of the IEngine::MultiProcessingParams property, ABBYY FineReader Engine can distribute processing of multi-page documents to CPU cores.
