RecognizeBlocks Method of the FRPage Object

RecognizeBlocks method of the FRPage Object in the ABBYY FineReader Engine API — Recognizes text and performs page synthesis in an explicitly specified set of blocks.

This method recognizes text and performs page synthesis in an explicitly specified set of blocks.

Syntax

C++

HRESULT RecognizeBlocks(
  IIntsCollection*          BlockIndices,
  ISynthesisParamsForPage*  SynthesisParamsForPage,
  IObjectsExtractionParams* ExtractionParams
);

C#

void RecognizeBlocks(
  IIntsCollection          BlockIndices,
  SynthesisParamsForPage  SynthesisParamsForPage,
  ObjectsExtractionParams ExtractionParams
);

Visual Basic .NET

Sub RecognizeBlocks( _
  BlockIndices As IIntsCollection, _
  [SynthesisParamsForPage As ISynthesisParamsForPage = Nothing], _
  [ExtractionParams As ObjectsExtractionParams = Nothing] _
)

Parameters

BlockIndices

[in] This parameter refers to the IntsCollection object that contains the indices of blocks to be recognized. This parameter may be 0, in which case all blocks on the page are 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 FRPage object.
