Mechanism Objects Compatibility with Version 10

This section describes all changes to mechanism objects which may require changes in the source code of your applications.

  • The obsolete DocumentAnalyzer and Exporter objects have been removed. Use the more efficient methods of the FRDocument and FRPage objects, which take care of all the information needed for full document processing. You are no longer required to maintain the DocumentInfo object on all processing stages, keep track of all the image documents with the corresponding layouts, or implement the IRecognizedPages interface.
    See below for recommendations on which methods should replace the methods of DocumentAnalyzer and Exporter you previously used.
Object/Enumeration Property/Method/Constant What has happened? Comment
DocumentAnalyzer Removed The object is obsolete. Its methods were replaced by more efficient methods of the FRDocument and FRPage objects, which do not require you to maintain the DocumentInfo object on all processing stages, or implement the IRecognizedPages interface.

AddWordsToCacheDictionary

AddWordToCacheDictionary

CleanCacheDictionary

Removed Use the IFRPage::AddWordsToCacheDictionary, IFRPage::AddWordToCacheDictionary, IFRPage::CleanCacheDictionary methods for working with cache dictionaries.
AnalyzePage Removed Use the IFRPage::Analyze method instead.
AnalyzePages Removed Use the IFRDocument::Analyze method instead.
AnalyzeRegion Removed Use the IFRPage::AnalyzeRegion method instead.
AnalyzeTable Removed Use the IFRPage::AnalyzeTable method instead.
AnalyzeAndRecognizePage Removed Use the IFRPage::PreprocessAnalyzeRecognize method instead.
AnalyzeAndRecognizePages Removed Use the IFRDocument::Process method instead. It performs full processing of the document, including document synthesis.
AutoCleanRecognizerSession Removed Use the IEngine::AutoCleanRecognizerSession property, which works in exactly the same way.
CleanRecognizerSession Removed Use the IEngine::CleanRecognizerSession method, which works in exactly the same way.
DetectOrientation Removed Use the IFRPage::DetectOrientation method instead.
ExtractBarcodes Removed Use the IFRPage::ExtractBarcodes method instead.
FindPageSplitPosition Removed Use the IFRPage::FindPageSplitPosition method instead.
LearnCheckmarks Removed Use the IFRPage::LearnCheckmarks method instead.
RecognizeBlocks Input parameters number changed Use the IFRPage::RecognizeBlocks method instead.
RecognizeImageAsPlainText Removed To recognize an image as plain text create the FRDocument from the image with the help of the IEngine::CreateFRDocumentFromImage method, use the IFRDocument::Process method to recognize the document, then access the IFRDocument::PlainText property.
RecognizeImageDocumentAsPlainText Removed To recognize the page as plain text, use the IFRPage::PreprocessAnalyzeRecognize method, then access the IFRPage::PlainText property.
RecognizePage Removed Use the IFRPage::Recognize method instead.
RecognizePages Removed Use the IFRDocument::Recognize method instead.
RemoveGeometricalDistortions Removed Use the IFRPage::CorrectGeometricalDistortions method instead.
IDocumentAnalyzerEvents Removed

This interface is no longer necessary because the object which reported events has been removed.

The IFRDocumentEvents and IFRPageEvents interfaces provide similar information on progress and errors for the objects which replaced DocumentAnalyzer.

Exporter Removed The object is obsolete. Its methods were replaced by more efficient methods of the FRDocument and FRPage objects, which do not require you to maintain the DocumentInfo object on all processing stages, or implement the IRecognizedPages interface.
ExportPage Removed Use the IFRPage::Export method instead.
ExportPagesEx Removed Use the IFRDocument::Export method instead.
IExporterEvents Removed

This interface is no longer necessary because the object which reported events has been removed.

The IFRDocumentEvents and IFRPageEvents interfaces provide similar information on progress and errors for the objects which replaced Exporter.

FREngineModuleEnum FREM_DocumentAnalyzer Removed This constant is no longer in use.
ScanManager ScanSources Type changed This property returns the ScanSources collection of scanning sources. New ScanSource interface provides access to extended scanning options.
ScanOptionsInterfaceType Removed To set the type of scanning options dialog box use the UserInterfaceType parameter of the Scan and BeginScan methods of the ScanSource object.
ScanSourceSettings Removed The settings are specified for each scanning source separately. Use the ScanSource::ScanSettings property to specify scanning source settings.
Scan Removed Use the Scan method of the ScanSource object for synchronous scanning operation. But note that asynchronous scanning is now also supported, via the BeginScan method of the ScanSource object.
IScanManagerEvents Removed This interface is no longer in use. The scanning notifications are received through new IScanCallback interface.
ScanSourceSettings

Brightness

Delay

Default value changed The default value of these properties is 0.

BrightnessControl

PaperSize

Resolution

RotationAngle

Default values changed The default values of these properties are determined by the scanner capabilities.
PictureMode Renamed, default value changed

The new name of this property is ColorMode.

The default value of this property depends on the scanner.

UseFeeder Removed Use the PaperFeedMode property instead.

StopBetweenPages

PauseBetweenPages

Removed Use the PauseBetweenPagesMode property instead.
ScanPictureModeEnum Renamed The new name of this enumeration is ScanColorModeEnum. The constants have been renamed likewise to have the SCM_ prefix instead of SPM_.
ScanPageRotationAngleEnum Renamed The new name of this enumeration is ScanRotationAngleEnum. The word Page is superfluous.
ScanOptionsInterfaceTypeEnum Removed The properties that used this enumeration have been removed. The ScanSourceUITypeEnum provides a similar set of constants.
