7.3 TIFF (Tagged Image File Format)

TIFF files are used for raster images. Raster images are represented by an array of dots (pixels); the most typical examples are the result of scanning a document or image. When compared with other raster file formats (e.g. GIF), TIFF is very widely supported (by most, if not all, image processing and viewing applications), and supports sophisticated colour management features. Consequently, TIFF is recommended for use when preserving a scanned image.

TIFF files must conform to the Baseline TIFF specification [TIFF].

In addition, the following compression extensions are allowed:

CCITT bilevel encodings.
LZW compression. Note that LZW compression is patented. This is actually of benefit in an archive, as a patent, by definition, contains sufficient detail to re-implement the algorithm.

No other extensions are supported.
