# DocumentProcessingParams Object (IDocumentProcessingParams Interface)

> DocumentProcessingParams object (IDocumentProcessingParams interface) in the ABBYY FineReader Engine API — Aggregates all parameters that affect document processing (page processing plus document-synthesis parameters); passed to document processing methods; persistent object savable to file/memory.

This object provides access to all parameters that affect document processing including all parameters of page processing and synthesis parameters for document. This object is passed as a parameter to the document processing methods.

The DocumentProcessingParams object is a persistent object. This means that the object's current state can be written to persistent storage. Later, the object can be re-created by reading the object's state from the persistent storage. The following methods provide persistence of the object:

Linux: [SaveToFile](/fine-reader/engine/api-reference/supplementary-objects-and-methods/savetofile-method), and [LoadFromFile](/fine-reader/engine/api-reference/supplementary-objects-and-methods/loadfromfile-method)

Windows [SaveToFile](/fine-reader/engine/api-reference/supplementary-objects-and-methods/savetofile-method), [LoadFromFile](/fine-reader/engine/api-reference/supplementary-objects-and-methods/loadfromfile-method), [SaveToMemory](/fine-reader/engine/api-reference/supplementary-objects-and-methods/savetomemory-method), and [LoadFromMemory](/fine-reader/engine/api-reference/supplementary-objects-and-methods/loadfrommemory-method).
