| AddFilter(String, Int32, Boolean) | Adds filter to exclude text objects with specified attributes. (Inherited from BaseTextExtractor.) |
| AddFilter(String, Int32, Color, Boolean) | Adds filter to exclude text objects with specified attributes. (Inherited from BaseTextExtractor.) |
| AddFilter(String, String, Boolean, Boolean) | Adds a filter to replace a text in extracted data. (Inherited from BaseTextExtractor.) |
| AddFilter(String, Int32, Int32, Int32, Int32, Boolean) | Adds filter to exclude text objects with specified attributes. (Inherited from BaseTextExtractor.) |
| CreateProfile(String, Boolean, Boolean, Boolean) | Creates JSON profile will all extractor properties with current values. (Inherited from BaseExtractor.) |
| CreateProfile(String, String, Boolean, Boolean, Boolean) | Creates JSON profile will all extractor properties with current values. (Inherited from BaseExtractor.) |
| Dispose | Releases the unmanaged resources used by the instance and optionally releases the managed resources. (Inherited from BaseExtractor.) |
| DisposePage | Disposes the page object. Uses this method carefully to destroy the page object that should not be used further. Useful to free allocated memory when processing huge PDF documents. (Inherited from BaseTextExtractor.) |
| Equals | (Inherited from Object.) |
 | Finalize | (Inherited from Object.) |
| FireParsingError | (Inherited from BaseExtractor.) |
| FireProgressChanged | (Inherited from BaseExtractor.) |
| GetHashCode | (Inherited from Object.) |
| GetJSONAsVariant | Returns extracted JSON data as array of bytes. This is COM/ActiveX-compatible version of the method SaveJSONToStream(Stream) for in-memory processing of PDF documents or images. |
| GetJSONAsVariant(String) | Returns extracted JSON data as array of bytes. This is COM/ActiveX-compatible version of the method SaveJSONToStream(String, Stream) for in-memory processing of PDF documents or images. |
| GetJSONAsVariant(Int32, Int32) | Returns extracted JSON data as array of bytes. This is COM/ActiveX-compatible version of the method SaveJSONToStream(Int32, Int32, Stream) for in-memory processing of PDF documents or images. |
| GetJSONData | Extracts data from whole document as JSON string. |
| GetJSONData(IListInt32) | Extracts data from specified pages as JSON string. |
| GetJSONData(Int32) | Extracts data from specified document page as JSON string. |
| GetJSONData(String) | Extracts data from specified page ranges as JSON string. |
| GetJSONData(Int32, Int32) | Extracts data from specified page range as JSON string. |
| GetPageCount | Returns document page count. (Inherited from BaseExtractor.) |
| GetPageRect_Height | Gets the specified page height. (Inherited from BaseExtractor.) |
| GetPageRect_Left | Gets the specified page left coordinate. (Inherited from BaseExtractor.) |
| GetPageRect_Top | Gets the specified page top coordinate. (Inherited from BaseExtractor.) |
| GetPageRect_Width | Gets the specified page width. (Inherited from BaseExtractor.) |
| GetPageRectangle(Int32) | Gets the page rectangle in PDF Points (1 Point = 1/72 in.). (Inherited from BaseExtractor.) |
| GetPageRectangle(Int32, Boolean) | Gets the page rectangle in PDF Points (1 Point = 1/72 in.). (Inherited from BaseExtractor.) |

| IsOCRRecommendedForPage | Detects whether OCR is recommended for specified page. OCR (Optical Character Recognition) is recommended when pages has no text objects bat has an image that might contain text. (Inherited from BaseTextExtractor.) |
| LoadAndApplyProfiles | Loads profiles from JSON string and automatically applies them. Note that profiles containing detection keywords will be deferred until the extraction. (Inherited from BaseExtractor.) |
| LoadDocumentFromFile | Loads PDF document from specified file. (Inherited from BaseExtractor.) |
| LoadDocumentFromStream | Loads PDF document from provided stream. (Inherited from BaseExtractor.) |
| LoadDocumentFromVariant | Loads PDF document from byte array presented as array of Variant or Byte objects ('Variant()' or 'Byte()'). This is COM/ActiveX-compatible version of the method LoadDocumentFromStream(Stream) for in-memory processing of PDF files. (Inherited from BaseExtractor.) |
| LoadProfiles | Loads profiles from JSON file. (Inherited from BaseExtractor.) |
| LoadProfilesFromString | Loads profiles from JSON string. (Inherited from BaseExtractor.) |
| MemberwiseClone | (Inherited from Object.) |
| PerformTextAnalysis | (Inherited from BaseTextExtractor.) |
| Reset | (Overrides BaseTextExtractorReset.) |
| ResetBaseExtractionData | (Inherited from BaseTextExtractor.) |
| ResetExtractionArea | Resets the extraction area to the full page. (Inherited from BaseExtractor.) |
| ResetFilters | Reset text filters. (Inherited from BaseTextExtractor.) |
