This object provides functionality for tuning the parameters of saving an image to TIFF format (all IFF_Tiff… image format types) using the IImage::WriteToFile method. A pointer to this object is passed into the IImage::WriteToFile method as an input parameter, and thus affects the size and quality of the resulting image. All properties of a newly created object of this type are set to reasonable defaults. See the description of particular property for its default value. The TiffExtendedParams 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, and LoadFromFile Windows SaveToFile, LoadFromFile, SaveToMemory, and LoadFromMemory.Documentation Index
