# DocumentProcessingParams Object (IDocumentProcessingParams Interface)

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)
