 | Engine | OCR engine An OCR engine is required for most OCR processing operations. Engines can be created using the static method Create(String). OCR engines can be reused to process multiple files. However, one OCR engine can only be used to process one file at a time. Note that some OCR engines must be disposed in the same thread where they have been created. Note that of some OCR engines only one instance can be created per process. |
| ImageOptions | Options for OCR processing of images These options control how images in the PDF document are processed during OCR. |
| OcrOptions | The options for OCR processing This class aggregates all OCR processing options including resolution settings, image processing, text processing and page processing. |
| PageOptions | Options for OCR processing of pages These options control page-level OCR processing and tagging. |
| Processor | Process PDF documents with OCR The processor applies Optical Character Recognition (OCR) to PDF documents. It can make scanned documents searchable, fix text extraction issues and generate PDF tagging/structure. The processor is decoupled from the document - it takes a Document as input and produces a new Document as output. |

| TextOptions | Options for OCR processing of text These options control how existing text in the PDF document is processed during OCR. |
