public class DataExtractionOptions : OptionsBase, IDisposable

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)

Adds an Inclusion Zone to the InclusionZonesForPage array. Optional list of page areas to be included in analysis (to the exclusion of all other areas). 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, only the areas specified will be analyzed. If neither this nor ExclusionZonesForPage is set, the entire page will be analyzed. This option only affects the GenericKeyValue, FormKeyValue, and FormField engines.

Declaration

public DataExtractionOptions AddInclusionZonesForPage(RectCollection regions, int pageNum)

Parameters

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

Returns

Type	Description
DataExtractionOptions	This object, for call chaining.

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.

Declaration

public bool GetDetectEmptyFields()

Returns

Type	Description
bool	The current value for DetectEmptyFields.

GetFormExtractionEngine()

Gets the value FormExtractionEngine from the options object. Specifies the form extraction engine used in DetectAndAddFormFieldsToPDF, either 'Form' or 'FormKeyValue'. The default is 'Form'.

Declaration

public string GetFormExtractionEngine()

Returns

Type	Description
string	Specifies the form extraction engine used in DetectAndAddFormFieldsToPDF, either 'Form' or 'FormKeyValue'. The default is 'Form'.

GetLanguage()

Gets the value Language from the options object. Specifies the OCR language(s). Use 3-letter ISO 639-2 language codes, separated by spaces. Example: "eng deu spa fra". The default is English.

Declaration

public string GetLanguage()

Returns

Type	Description
string	Specifies the OCR language(s). Use 3-letter ISO 639-2 language codes, separated by spaces. Example: "eng deu spa fra". The default is English.

GetMinimumConfidenceThreshold()

Gets the value MinimumConfidenceThreshold from the options object. Specifies the minimum confidence threshold for a class to be accepted in the DocClassification engine. The default is 0.25. Classes that don't meet the minimum threshold will not be listed in the output JSON. This setting only affects the DocClassification engine.

Declaration

public double GetMinimumConfidenceThreshold()

Returns

Type	Description
double	The current value for MinimumConfidenceThreshold.

GetOverlappingFormFieldBehavior()

Gets the value OverlappingFormFieldBehavior from the options object. When a detected form field overlaps with an existing one, keep either the old field (value 'KeepOld'), or the new one (value 'KeepNew', default).

Declaration

public string GetOverlappingFormFieldBehavior()

Returns

Type	Description
string	When a detected form field overlaps with an existing one, keep either the old field (value 'KeepOld'), or the new one (value 'KeepNew', default).

GetPDFPassword()

Gets the value PDFPassword from the options object. Specifies the password if the PDF requires one. The default is no password.

Declaration

public string GetPDFPassword()

Returns

Type	Description
string	Specifies the password if the PDF requires one. The default is no password.

GetPages()

Gets the value Pages from the options object. Specifies a range of pages to be converted, such as "1-5". By default all pages are converted. The first page has the page number of 1.

Declaration
