# EBookExportParams Object (IEBookExportParams Interface)

This object provides functionality for tuning of parameters of recognized text export in FB2 and EPUB formats by means of ABBYY FineReader Engine export functions.

A pointer to this object is passed into the export methods as an input parameter, and thus affects the results of export. All properties of a newly created object of this type are set to reasonable defaults. For more information about the default value of this or that property, see the description of the corresponding property.

The EBookExportParams 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).
