TIFF -supports a wide variety of storage and data compression schemes that -can be used to optimize retrieval time and/or minimize storage space. -These on-disk formats are independent of the image characteristics; it -is the responsibility of the TIFF reader to process the on-disk storage -into an in-memory format suitable for an application. Furthermore, it -is the responsibility of the application to properly interpret the -visual characteristics of the image data. TIFF defines a framework for -specifying the on-disk storage format and image characteristics with -few restrictions. This permits significant complexity that can be -daunting.
