58 Normally, you need not call the TIFF functions directly. They are
59 available much more conveniently via \ref importImage() and \ref exportImage()
60
61 TIFF (Tagged Image File Format) is a very versatile image format -
62 one can store different pixel types (byte, integer, float, double) and
63 color models (black and white, RGB, mapped RGB, other color systems).
64 For more details and information on how to create a TIFF image,
65 refer to the TIFF documentation at
66 <a href="http://www.libtiff.org/">http://www.libtiff.org/</a> for details.
