(Inherited from BaseExtractor.)
Public propertyComHelpers
Set of utility functions and properties to use from COM/ActiveX.
(Inherited from BaseExtractor.)
Public propertyContentType
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.
(Inherited from BaseExtractor.)
Public propertyEmbeddedFileCountObsolete.
Property is disabled to speed up the document loading. Use AttachmentExtractor to work with attachments.
(Inherited from BaseExtractor.)
Public propertyEncrypted
Gets whether the document is encrypted.
(Inherited from BaseExtractor.)
Public propertyExtractionArea
Sets the extraction area by coordinates and dimensions (left, top, width, height).
(Inherited from BaseExtractor.)
Public propertyExtractionAreaRect
Sets the extraction area by rectangle.
(Inherited from BaseExtractor.)
Public propertyExtractionAreaUsageMode
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.
(Inherited from BaseExtractor.)
Public propertyExtractRawImages
Controls if we need to enable extraction of raw images (preserving the original dimensions of raw image saved inside PDF). True causes to extract images with their original dimensions. False causes to extract images rescaled according to scaling and skews defined for rendering (so image extractor provides images similar to what you see).
Public propertyIsDocumentLoaded
Get the document loaded state.

Gets license information.
(Inherited from BaseExtractor.)
Public propertyPageDataCaching
Controls page data caching behavior.

Public propertyPassword
PDF document password.
(Inherited from BaseExtractor.)
Public propertyProfiles
Comma-separated list of profiles to apply to the extractor. Profiles must be previously loaded.
(Inherited from BaseExtractor.)
Public propertyRegistrationKey
Registration key.
(Inherited from BaseExtractor.)
Public propertyRegistrationName
