Engine Object API Compatibility with Version 10
This section describes all changes to the Engine object which may require changes in the source code of your applications.
Property/Method | What has happened? | Comment |
---|---|---|
Licenses | Removed | Use the IEngine::GetAvailableLicenses method instead. |
SetCurrentLicense | Input parameters changed |
Project ID number is no longer used as an input parameter. You pass this parameter to the IEngine::GetAvailableLicenses method, and all licenses in the collection it returns have the same Customer Project ID. The method takes as an input parameter a Boolean value that specifies whether CPU cores should be used in shared mode. This is because when you reset the license for the application, in effect you re-initialize it. So you need to set shared core usage mode again, as you do when you obtain the Engine object. |
OpenExistingDictionary CreateNewDictionary CreateTextLanguage |
Removed |
Use corresponding methods of the LanguageDatabase object. It is more convenient to have the language-related methods in language-related object, and the Engine object API becomes less massive. |
CreateBaseLanguage | Removed |
Use the AddNew method of the BaseLanguages object instead. It is more convenient to have this creation method in corresponding collection object, and the Engine object API becomes less massive. |
CreateStandardDictionaryDesc CreateUserDictionaryDesc CreateRegExpDictionaryDesc CreateExternalDictionaryDesc |
Removed |
Use the AddNew method of the DictionaryDescriptions object to create a dictionary description and the GetAsStandardDictionaryDescription, GetAsUserDictionaryDescription, GetAsRegExpDictionaryDescription, or GetAsExternalDictionaryDescription methods of the DictionaryDescription object to obtain a reference to the object of the corresponding type. It makes sense to have the methods for dictionary descriptions creation in dictionary descriptions collection, and the Engine object API becomes less massive. |
CreateLayoutBlocks | Removed | The method is obsolete and is no longer in use. The LayoutBlocks object cannot be an independent object, it exists only as a subobject of the Layout object. Use the properties of the Layout object to obtain collections of blocks. |
PrepareMemoryImage | Renamed |
The new name of the method is PrepareBitmapBits. This name is more appropriate for new memory image format — bitmap data. The pointer to a memory buffer containing image data is passed as __int64. |
PrepareAndOpenMemoryImage | Renamed |
The new name of the methodis OpenBitmapBits. Now all methods working with images conform to the same naming convention:
The pointer to a memory buffer containing image data is passed as __int64. |
OpenImage | Renamed |
The new name of the method is LoadImageDoc. Now all methods working with images conform to the same naming convention:
|
OpenMemoryImage | Removed | Use the OpenBitmapBits method instead. The difference is that it can optionally perform image preparation during conversion to the internal format. |
OpenImageFileFromMemory | Input parameters number changed |
|
AnalyzePage RecognizePage AnalyzePages RecognizePages RecognizeImageAsPlainText RecognizeImageDocumentAsPlainText AnalyzeAndRecognizePage AnalyzeAndRecognizePages SynthesizePages SynthesizePagesEx |
Removed |
Use the methods of the FRDocument and FRPage objects instead. These were the methods that performed specific processing stages. The Engine object is intended for use in basic scenarios. Most methods it provides combine many processing stages in one. |
RecognizeImageFile | Input parameters number changed | The method receives all processing and synthesis parameters as one DocumentProcessingParams object. |
CreatePDFExportParamsOld CreatePDFAExportParamsOld |
Removed | These methods are obsolete. To create parameters of export to PDF, PDF/A formats, use the IEngine::CreatePDFExportParams method. |
CreatePdfExtendedParams CreateImageDocumentsCollection CreateLayoutsCollection |
Removed | The methods are obsolete, corresponding objects are no longer in use. |
CreatePDFEncryptionInfo | Removed | The method is obsolete and is no longer in use. To obtain the PDFEncryptionInfo object, you can use the EncryptionInfo property of the PDFExportFeatures object. |
RestartLicening | Renamed | There was a misprint in the method name. It is now called RestartLicensing. |
CreateDocumentAnalyzer CreateDocumentInfo CreateExporter |
Removed | The methods are not necessary anymore as the objects they created have been removed. |
CreateLayout | Removed | The Layout object can no longer be used apart from the page it corresponds to. |
CreateMultipageImageWriter | Behavior changed | This method now accepts extended image saving parameters for JPEG and TIFF formats. |
ExportPage | Removed | Use the IFRPage::Export method instead. |
ExportPages | Removed | Use the IFRDocument::Export method instead. |
PrepareAndOpenImage | Removed | Use the IFRDocument::AddImageFile method to open an image file and add it to the document for processing. The ImageDocument object will be accessible via the corresponding FRPage. |
PrepareImage | Removed | Use the IFRDocument::AddImageFile method to open an image file and add it to the document for processing. The ImageDocument object will be accessible via the corresponding FRPage and can be saved on disk later. |
