ABBYY FineReader Engine 12 and 9.0/9.5 Compatibility

ABBYY FineReader Engine 12 is not binary compatible with ABBYY FineReader Engine 9.0/9.5. Applications that were compiled using ABBYY FineReader Engine 9.0/9.5 should be recompiled using ABBYY FineReader Engine 12 headers and library. Some changes of the source code may be necessary because of the ABBYY FineReader Engine API improvements.

The full list of changes:

long data type has been replaced with int data type in all properties and methods that used it.
The GetEngineObject function was removed from ABBYY FineReader Engine. The Engine object must now be loaded by the InitializeEngine function.
The SaveToMemory method provided by many objects returns the handle to the memory buffer as the Handle object.
The LoadFromMemory method provided by many objects receives the pointer to the memory buffer as __int64.

Text-related objects

Object/Enumeration	Property/Method/Constant	What has happened?	Comment
Paragraphs	Find	Renamed	The new name of the method is IndexOf.

	IsMirrored	Removed	This property is no longer supported.
	Append	Removed	You can use the InsertText method of the Paragraph object instead.
	IsPlain CopyFrom	Removed	The functionality is no longer supported. In this version text is usually associated to some place in the document and cannot be simply copied from one object to another without specifying its location. Therefore to copy some text from one location to another, you can use the IText::AppendEmptyParagraph and IParagraph::InsertText methods.
	DiscardExtendedRecAttributes	Removed	The ExtendedRecAttributes object is no longer in use. If you do not need to use additional attributes of characters and words, keep the SaveCharacterRecognitionVariants, SaveWordRecognitionVariants properties of the RecognizerParams object set to FALSE during recognition.

	SetCharParams	Input parameters number changed	The method takes an OR combination of the StyleParamsEnum constants as one of the input parameters.
	Left Top Right Bottom	Behavior changed	The coordinates of the paragraph borders are not available for the paragraphs of barcodes. You can obtain the coordinates of separate symbols in a recognized barcode using the Left, Top, Right, Bottom properties of the BarcodeSymbol object.

ParagraphLine	BaseLine	Attribute changed	The property becomes read-only.
	Left Top Right Bottom	Behavior changed	The coordinates of the line borders are not available for the paragraphs of barcodes. You can obtain the coordinates of separate symbols in a recognized barcode using the Left, Top, Right, Bottom properties of the BarcodeSymbol object.
	SetRect	Removed	This functionality is no longer supported. The coordinates of a paragraph line are read-only and are provided for reference. The coordinates can be only defined for blocks (IBlock::Region property).
ParagraphTabInfo		Removed	The same functionality is provided via the TabPosition object.
CharParams	IsHidden	Removed	The property is obsolete. Recognized characters cannot have this attribute. If you want to assign some user- specific information to a character, you can use bookmarks in the paragraph (IParagraph::Bookmark property).
	IsStartStopSymbol	Removed	Use the IsStartStopSymbol property of the BarcodeSymbol object instead.
	ExtendedRecAttributes	Removed	This object is no longer in use. Similar properties are available via the CharacterRecоgnitionVariant and WordRecognitionVariant object.
	CharacterHeight HasUncertainHeight	Removed	These properties are no longer supported. You can obtain detailed information on character configuration via the ICharParams::CharacterRegion property.
ExtendedRecAttributes		Removed	Use the CharacterRecognitionVariant, WordRecognitionVariant, and CharParams objects instead: CharConfidence, SerifProbability — use the corresponding properties of the CharacterRecоgnitionVariant object. IsWordFromDictionary, MeanStrokeWidth — use the corresponding properties of the WordRecognitionVariant object. IsWordIdentifier, IsWordNormal, IsWordNumeric — use the ModelType property of the WordRecognitionVariant object: IsWordNormal set to TRUE is equal to the ModelType property set to WMT_MonoLingualWord \| WMT_RegExpWord IsWordNumeric set to TRUE — to WMT_Number \| WMT_NumberWithQualifier \| WMT_RomanNumber \| WMT_PhoneNumber \| WMT_UrlOrEmail IsWordIdentifier set to TRUE — to WMT_BilingualComposit \| WMT_Acronym \| NumberWithQualifier \| WMT_WordNumberComposite \| WMT_BilingualWordNumberComposite \| WMT_RomanNumber \| WMT_MixedFormDictionaryWord \| WMT_PhoneNumber \| WMT_Punctuation \| WMT_FileName \| WMT_UrlOrEmail WordPenalty — use the WordConfidence property of the WordRecognitionVariant object. IsWordStart — use the IsWordFirst or IsWordLeftmost properties of the CharParams object.
CFL_ prefixed flags		Renamed	The new name of the module is CharacterFlags.
	CFL_Bold CFL_Italic CFL_Underlined CFL_Strikeout CFL_SmallCaps CFL_FontSize CFL_FontName CFL_Scale CFL_Spacing CFL_Color CFL_BaseLine	Removed	Use the corresponding constants of the StyleParamsEnum enumeration.
	CFL_Hidden CFL_UncertainCharHeight CFL_CharacterHeight CFL_ExtRecAttributes CFL_Rectangle CFL_IsStartStopSymbol	Removed	These constants are no longer in use. Corresponding properties of the CharParams object are no longer supported.
PlainText	SaveToTextFile	Input parameters number changed	The following input parameters have been added: encoding type and code page of the output file. The bUnicode input parameter has been removed; this setting is covered by the encoding type parameter.

As this type of block is no longer supported the methods have been removed. You can use the AnalyzeRegion method to perform layout analysis in an image zone, and then call the RecognizeBlocks method.
	Analyze AnalyzeTable	Input parameters number changed	The methods take as input parameters a set of subobjects of the PageProcessingParams object — only those parameters that are needed for page analysis are passed to these methods. The Analyze method does not perform correction of page orientation, inversion, and geometrical distortions any more. To preprocess the image, use corresponding methods of the FRPage object, or perform all these operations as a whole using the IFRPage::Preprocess method.
	AnalyzeAndRecognize	Renamed	The new name of the method is PreprocessAnalyzeRecognize. The only difference from the old method is that now this method receives only one input parameter of the PageProcessingParams type, which contains all the necessary settings for processing.
	Recognize RecognizeBlocks	Input parameters number changed	These methods now additionally receive the ObjectsExtractionParams object as an input parameter.
	Flush	Input parameters number changed	This method receives a boolean input parameter specifying whether the data should be saved to disk. This is useful in case the data is unchanged.

	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.
