    00057
    00058     Normally, you need not call the TIFF functions directly. They are
    00059     available much more conveniently via \ref importImage() and \ref exportImage()
    00060
    00061     TIFF (Tagged Image File Format) is a very versatile image format -
    00062     one can store different pixel types (byte, integer, float, double) and
    00063     color models (black and white, RGB, mapped RGB, other color systems).
    00064     For more details and information on how to create a TIFF image,
    00065     refer to the TIFF documentation at
    00066     <a href="http://www.libtiff.org/">http://www.libtiff.org/</a> for details.

    01437     Type and size of the TiffImage are determined by the input image
    01438     (may be one of unsigned char, int, float, or double).
    01439     This function uses \ref RGBAccessor to read the data. A
    01440     RGBImageIterator is an iterator that is associated with a
    01441     RGBAccessor.
