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.DefaultCharacterFilter | Enum | None, Digit, Uppercase, Lowercase, Punctuation, Miscellaneous, Plus | Specifies which character set (Global filter) will be applied globally, at page level. |
| 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. |
| Recognition.IcrNumeral.EnableSpaceInclusion | Boolean | N/A | Controls whether the handprinted numeral recognition module should export spaces detected between characters. |
| End:Recognition.IcrNumeral | EndCategory | N/A | End of the ICR (Handprint) recognition settings category. |
