The IOcrSettingManager.GetSettingNames method will return the names of the values as described in this table and in the same order.

The following table describes the settings supported by the LEADTOOLS OCR Plus Engine:

Name	Type	Range and values	Description
Engine	BeginCategory	N/A	Beginning of the engine settings category
Engine.Timeout	Integer	-1 to Int32.MaxValue	Gets or sets the engine-wide module timeout setting in milliseconds. This setting is used by the engine to implement a watch-dog feature for avoiding rare but annoying dead-lock situations (infinite loops). Currently this feature applies to the following processes of the engine: page preprocessing, page zoning, page recognition. A value of -1 (infinite) disables the watch-dog mechanism in the engine. The default value of this setting is 180000 milliseconds (3 minutes).
End:Engine	EndCategory	N/A	End of the engine settings category
Recognition	BeginCategory	N/A	Beginning of the recognition settings category.

Recognition.ForceSingleColumn	Boolean	N/A	Force single column mode for the page-layout. It prevents the engine decolumnization detecting columns and placing their contents one below the other. It is useful for conserving the columnar structure in tables.
Recognition.DetectNonGriddedTable	Boolean	N/A	Detect Non-gridded tables.
Recognition.EnableMorFaxMode	Boolean	N/A	Switches Fax image mode for multi-lingual omnifont recognition on or off. Turn this setting on if the image file to be loaded is a fax message transmitted in "Draft" mode at 200 x 100 resolution. Do not use this switch to read fax card image files transmitted in "Fine" mode (200 x 200 dpi resolution).
Recognition.RecognitionModuleTradeoff	Enum	Accurate, Balanced, Fast	Specifies which recognition algorithm trade-off setting to use for recognition.
Recognition.EnableParallelRecognition	Boolean	N/A	Enable parallel recognition if applicable. This setting is being deprecated and should not be used.

Recognition.IcrNumeral.CharacterBoxData.LeadingSpaces	Integer	0 to Int32.MaxValue	Leading spaces in 1/1200 inches. A value of zero (0) forces automatic calculation of this setting.
