Set of utility functions and properties to use from COM/ActiveX.

Returns content type of PDF document: normal document, portfolio or XFA form. To extract files from PDF portfolio use AttachmentExtractor class. To extract XFA form content use XFAFormExtractor class.

Gets or sets whether to discard any existing text in the document. Default is false (combine the recognized text with existing content).

Property is disabled to speed up the document loading. Use AttachmentExtractor to work with attachments.

Gets whether the document is encrypted.

Sets the extraction area by coordinates and dimensions (left, top, width, height).

Sets the extraction area by rectangle.

Gets or sets how to use the ExtractionArea: whether to extract any object intersecting with the area or only objects completely located inside the area.

Get the document loaded state.

Gets or sets whether to keep the original rotation of the document after making it searchable. Default is false.

Font used to put invisible text. By default the "Helvetica" is used, but this font does not contain Unicode character ranges. If you process document containing Chinese, Japanese, Korean characters (or any other Unicode charsets) you should set the font name containing required characters, for example, "Arial Unicode MS", "Microsoft JhengHei", etc.

Gets license information.

Collection of corrections automatically applied to recognized text to fix repeating recognition errors.

Detect scanned page rotation. Slightly slows down the processing time.

Sets whether to disable the automatic segmentation. All pages will be treated as containing sparse text (as a typical document such as an invoice).

Collection of image processing filters applied to the document page before Optical Character Recognition (OCR). May improve the recognition quality.

Language for Optical Character Recognition (OCR). The valid values are:

• "eng" - English (default)
• "deu" - German
• "fra" - French
• "spa" - Spanish

Folder containing OCR language data files.

Gets or sets maximum OCR performance using Intel OpenMP (if available) to accelerate to approximately 30%. Default is false.

Gets overall OCR confidence. This value is calculated after the extraction is performed.

Resolution of Optical Character Recognition (OCR). Default is 300 DPI.

Controls page data caching behavior.

PDF document password.

Comma-separated list of profiles to apply to the extractor. Profiles must be previously loaded.

Registration key.

Registration name.

Gets the component version number.

Creates JSON profile will all extractor properties with current values.

Creates JSON profile will all extractor properties with current values.

Releases the unmanaged resources used by the instance and optionally releases the managed resources.

Returns document page count.

Processes the document with OCR (Optical Character Recognition), adds returns recognized data as array of OCRCell.

Processes the document with OCR (Optical Character Recognition), and returns recognized data as array of OCRCell.

Gets the specified page height.

Gets the specified page left coordinate.

Gets the specified page top coordinate.

Gets the specified page width.

Gets the page rectangle in PDF Points (1 Point = 1/72 in.).

Gets the page rectangle in PDF Points (1 Point = 1/72 in.).

Returns the rotation angle of specified page.

Gets the document encrypted state.

Loads profiles from JSON string and automatically applies them. Note that profiles containing detection keywords will be deferred until the extraction.

Loads PDF document from specified file.

Loads PDF document from provided stream.

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.

Loads profiles from JSON file.

Loads profiles from JSON string.

Resets the instance and disposes internal resources. Also automatically invoked by Dispose.

Resets the extraction area to the full page.

Sets the extraction area by rectangle.

Sets the extraction area by coordinates and dimensions.

Raised on PDF document parsing errors. This usually indicates a damaged document.

Occurs when the password required to decrypt the document.

Raised for each reported progress value. Allows to cancel the processing.
