Parameter Objects Compatibility with Version 10

Preprocessing, analysis, recognition, and synthesis parameters

Object/Enumeration	Property/Method/Constant	What has happened?	Comment
PageProcessingParams	DetectInvertedImage DetectOrientation OrientationDetectionParams RemoveGeometricalDistortions	Removed	Use the CorrectInvertedImage, CorrectOrientation, OrientationDetectionParams, CorrectGeometry properties of the PagePreprocessingParams subobject. There is a new stage concerned with image preprocessing, and settings used at that stage were grouped into a separate object to make the structure of parameters objects clearer and more logical.
	PerformPageAnalysis	Renamed	Use the PerformAnalysis property to enable layout analysis and PerformPreprocessing property to enable correction of page orientation, inversion, and geometrical distortions. The image preprocessing stage has been separated from page analysis and has its own set of parameters.
	BarcodeParams DetectBarcodes	Removed	Use the corresponding properties of the PageAnalysisParams subobject. Many processing parameters were grouped into subobjects to make the structure of parameters objects clearer and more logical.
BarcodeParams	PDF417CodePage	Renamed	The new name of the property is CodePage. This property can be used for barcodes of several types besides PDF417.
PageAnalysisParams	SingleColumnMode	Removed	This property is no longer supported in FineReader Engine recognition technologies.
RecognizerParams	ErrorHiliteLevel	Removed	Use the new HighlightSuspiciousCharacters property, which dispenses with various levels of confidence and allows you a simple choice: either highlight uncertainly recognized characters or not. If you need a finer distinction, use the CharConfidence property of the selected CharacterRecognitionVariant, although matching recognition confidences for different characters against the same threshold may not always provide consistent results.
	DetectLanguage	Removed	Use the LanguageDetectionMode property to manage automatic detection of recognition languages.
	TextLanguage	An attribute of the property has been changed	The property is described by the propput keyword in the type library. Former description as putref didn't make a difference because this property is an interface pointer in any case.
	PossibleTextTypes TextType	Removed	The properties are obsolete and were deprecated in the previous version. Use the TextTypes property instead.
	CJKTextDirection	Removed	Use the ITextOrientation::ReadingType property instead. If you set this property to TRT_Unknown, text direction will be detected automatically. By default, this property is TRT_Unknown as well.
WritingStyleEnum	WS_Default	Removed	We recommend using WS_Auto to ensure the best recognition quality. If you need to select the writing style corresponding to the current operating system language, use WS_DetectByLocale.
FieldMarkingTypeEnum	FMT_GreyBoxes	Renamed	The new name of the constant is FMT_GrayBoxes.
TextTypeEnum	TT_ToBeDetected	Removed	The constant is obsolete. To detect text type automatically, specify a set of possible text types in the IRecognizerParams::TextTypes property.
SynthesisParamsForDocument	AddRecognizedTextFontName GetRecognizedTextFontName CleanRecognizedTextFontNames RecognizedTextFontCount AdjustRecognizedTextFonts	Removed	Use the FontSet object instead. This object is configured by default for easiest use in different recognition languages. FineReader Engine can filter all system fonts on the basis of recognition languages specified for the text and add them to the synthesis font set.
SynthesisParamsForDocument	SaveRecognitionInfo	Removed	This property had no effect on the program operation. If you want to save recognition information, use the SaveCharacterRecognitionVariants or SaveWordRecognitionVariants property of the RecognizerParams object.
SynthesisParamsForPage	InsertEmptyParagraphsForBigInterlines	Removed	Use the ITextExportParams::RetainLayout property to emulate the original text layout with the help of spaces.
	AllowGrayBackgroundColor AllowGrayTextColor CorrectDynamicRange DetectBackgroundColor DetectTextColor	Type changed	These properties now take values of the new ThreeStatePropertyValueEnum, which provides the opportunity not only to turn the setting on and off, but also make the selection automatically (TSPV_Auto constant). All these properties have TSPV_Auto value by default.
	FontFormattingDetectionParams	Type changed	The property provides access to the FontFormattingDetectionParams object. The parameters of font formatting detection at the stage of page synthesis and document synthesis are the same now. Formerly different parameters were used for font detection on page level to speed up document synthesis, and page font detection had to be less thorough to be quick. Now the same font detection is available for page synthesis without speed loss. However, note that if the document has similar style and fonts for all pages, the results of font detection on document level are still more reliable than on pages one-by-one.
ParagraphExtractionModeEnum	PEM_SingleLineParagraphsWithSpaceFormatting	Removed	Use the ITextExportParams::RetainLayout property to emulate the original text appearance with the help of spaces while exporting to TXT format.
FontFormattingDetectionParamsForPage		Removed	This object is no longer in use. Use the FontFormattingDetectionParams object instead. The parameters of font formatting detection at the stage of page synthesis and document synthesis are the same now. Formerly different parameters were used for font detection on page level to speed up document synthesis, and page font detection had to be less thorough to be quick. Now the same font detection is available for page synthesis without speed loss.
FontFormattingDetectionParams	DetectMonospace	Removed	Use the MonospaceDetectionMode property instead. If you do not want monospaced typeface to be detected, set the MonospaceDetectionMode property to MDM_Ignore.
ProcessingParams		Renamed	Use the DocumentProcessingParams object instead. The object provides the same functionality with the following exceptions: The SynthesisParamsForPage property of the old object has been moved to the PageProcessingParams subobject. The signature of the SaveToMemory method has been changed.
ObjectsExtractionParams	FlexiFormsDA	Removed	This property is obsolete since FineReader Engine 11. Use the EnableAggressiveTextExtraction property and the IPageAnalysisParams::EnableTextExtractionMode property instead.
	FullTextIndexDA	Removed	This property is obsolete since FineReader Engine 11. Use the DetectTextOnPictures property instead.
	SourceContentReuseMode	Default value changed	The default value of this property is now CRM_Auto. This setting uses both the text and the image layer of the PDF file and ensures the highest quality of objects extraction.
ErrorHiliteLevelEnum		Removed	The property which used this enumeration has been removed.

Export parameters

Object/Enumeration	Property/Method/Constant	What has happened?	Comment
HTMLExportParams	PictureFormat PictureJpegQuality PictureResolution	Removed	Use the ColorPictureFormats, GrayPictureFormats, JpegQuality, Resolution properties of the PictureExportParams subobject instead. This object now contains all parameters for picture export to all formats except PDF.

	EncodingType	Default value changed	By default, the value of this property is TET_Auto: when the export format is specified by the FEF_TextVersion10Defaults constant, this property resolves into TET_Simple — effectively the same behavior as in 10th version and only retained for compatibility; when the export format is specified by the FEF_TextUnicodeDefaults constant, this property resolves into TET_UTF8. This setting is recommended.
XLExportParams	RetainLayout	Removed	Use the LayoutRetentionMode property instead.

Other parameters

Object/Enumeration	Property/Method/Constant	What has happened?	Comment
MultiProcessingParams	SharedCPUCoresMode	Removed	To use CPU cores in shared mode, you should set the IsSharedCPUCoresMode parameter of the InitializeEngine function to TRUE during initialization. If you need shared core usage, setting this mode at initialization time is safer. Formerly, the cores were loaded as isolated and then transferred to shared, which could cause problems when starting several applications at once.
SharedCPUCoresMask	Type changed	The property has the __int64 type. This change has been made for 64-bit operating systems support.
