File Formats: Interchange File Format (IFF)

IFF (Amiga Interchange) is a general-purpose data storage format (raster), developed by Electronic Arts, Inc. and Commodore-Amiga, Inc. that can associate and store multiple types of data. It is used by the ACD FotoCanvas Lite 2.0 and XnView applications.

IFF reads and writes RLE and non-compressed images. IFF CAT supports multipage files.

The default extension for this format is: IFF.

The file constants associated with this file format are:

Constant	Read Support	Write Support	Description
IffIlbm	1, 2, 3, 4, 5, 6, 7, 8, 24 BPP	1, 2, 3, 4, 5, 6, 7, 8, 24 BPP	Interchange File - RLE Compressed.
IffCat	1, 2, 3, 4, 5, 6, 7, 8, 24 BPP	1, 2, 3, 4, 5, 6, 7, 8, 24 BPP	Interchange File - multiple images per file-RLE Compressed.
IffIlbmUncompressed	1, 2, 3, 4, 5, 6, 7, 8, 24 BPP	1, 2, 3, 4, 5, 6, 7, 8, 24 BPP	Interchange File - Uncompressed.
IffCatUncompressed	1, 2, 3, 4, 5, 6, 7, 8, 24 BPP	1, 2, 3, 4, 5, 6, 7, 8, 24 BPP	Interchange File - multiple images per file-Uncompressed.

Required DLL: Leadtools.Codecs.Iff.Dll. For a listing of the exact DLLs needed, based on the toolkit version, refer to Files To Be Included With Your Application .

NOTE: This format does not support LEAD's redirected IO feature, therefore it cannot be used with the overloads of Load that take an inputstream parameter or FeedLoad.
