TIFF

Revision as of 17:17, 26 November 2012

TIFF, formerly known as Tag(ged) Image File Format, is an image format capable of storing multiple high quality images in a single file.

A TIFF image may be uncompressed or use a compression scheme internally. Two of the most widely used compression schemes in TIFF files are lossless, including LZW and, for bitonal images CCITT Group 4, as used for facsimile transmission [fax]. JPEG baseline DCT-based lossy compression is also used.

Several subtypes and extensions of TIFF exist, including: TIFF/EP, TIFF/IT, DNG, GeoTIFF, and BigTIFF. Multi-image TIFFs may represent sequences of images (such as scanned pages of a document), image tiles, or different versions of the same image, for example Pyramid TIFFs that incorporate images at different resolutions (often tiled). Some software that can read and display a TIFF file may only open the primary image.
