##### Syntax

    public class DataExtractionOptions : OptionsBase

### Constructors

#### DataExtractionOptions()

Constructor.

##### Declaration

    public DataExtractionOptions()

### Methods

#### AddExclusionZonesForPage(RectCollection, int)

Adds an Exclusion Zone to the ExclusionZonesForPage array. Optional list of page areas to be excluded from analysis. Zones should be provided as a collection of Rects paired with a page number. The Rects are then applied to the corresponding page. Rects are specified in User Space coordinates. If this is set, the specified areas will not be analyzed. If neither this nor InclusionZonesForPage is set, the entire page will be analyzed. This option only affects the GenericKeyValue, FormKeyValue, and FormField engines.

##### Declaration

    public DataExtractionOptions AddExclusionZonesForPage(RectCollection regions, int pageNum)

##### Parameters

Type | Name | Description
--- | --- | ---
RectCollection | regions | List of page areas to be excluded from analysis.
int | pageNum | The page number (1-indexed) to which the regions are applied.

##### Returns

Type | Description
--- | ---
DataExtractionOptions | This object, for call chaining.

#### AddInclusionZonesForPage(RectCollection, int)

##### Declaration

    public DataExtractionOptions AddInclusionZonesForPage(RectCollection regions, int pageNum)

##### Parameters

Type | Name | Description
--- | --- | ---
RectCollection | regions |
int | pageNum |

##### Returns

Type | Description

#### GetDeepLearningAssist()

Gets the value DeepLearningAssist from the options object. Specifies if Deep Learning is used with table recognition in the DocStructure engine. The default is false. When true, table recognition accuracy improves at the cost of increased processing time. This only affects the DocStructure engine.

##### Declaration

    public bool GetDeepLearningAssist()

##### Returns

Type | Description
--- | ---
bool | Specifies if Deep Learning is used with table recognition in the DocStructure engine. The default is false. When true, table recognition accuracy improves at the cost of increased processing time. This only affects the DocStructure engine.

#### GetDetectEmptyFields()

Gets the value DetectEmptyFields from the options object. Specifies if empty fields should be recognized in the GenericKeyValue engine. The default is true. Users who don't require empty fields could benefit from setting this option to false, thus reducing processing time. This setting only affects the GenericKeyValue engine.

    public bool GetDetectEmptyFields()

##### Returns

Type | Description
--- | ---
bool | The current value for DetectEmptyFields.
