  20           The library is capable of dealing with images that are written to
  21           follow the 5.0 or 6.0 TIFF spec.  There is also considerable support
  22           for some of the more esoteric portions of the 6.0 TIFF spec.

 617     The <tt>Matteing</tt> and <tt>DataType</tt>
 618     tags have been obsoleted by the 6.0
 619     <tt>ExtraSamples</tt> and <tt>SampleFormat</tt> tags.
 620     Consult the documentation on the
 621     <tt>ExtraSamples</tt> tag and Associated Alpha for elaboration.  Note however
 622     that if you use Associated Alpha, you are expected to save data that is
 623     pre-multipled by Alpha.  If this means nothing to you, check out
 624     Porter &amp; Duff's paper in the '84 SIGGRAPH proceedings: "Compositing Digital
 625     Images".

 627   <p>
 628     The <tt>ImageDepth</tt>
 629     tag is a non-standard, but registered tag that specifies
 630     the Z-dimension of volumetric data.  The combination of <tt>ImageWidth</tt>,
 631     <tt>ImageLength</tt>, and <tt>ImageDepth</tt>,
 632     defines a 3D volume of pixels that are
 633     further specified by <tt>BitsPerSample</tt> and
 634     <tt>SamplesPerPixel</tt>.  The <tt>TileDepth</tt>
 635     tag (also non-standard, but registered) can be used to specified a
 636     subvolume "tiling" of a volume of data.
 637   </p>
 638   <p>
 639     The Colorimetry, and CMYK tags are additions that appear in TIFF 6.0.
 640     Consult the TIFF 6.0 specification included in the <b>doc</b> directory
 641     and <a href="document.html">online</a>.
 642   </p>
 643   <p>
 644     The JPEG-related tag is specified in
 645     <a href="TIFFTechNote2.html">TIFF Technical Note #2</a> which defines
 646     a revised JPEG-in-TIFF scheme (revised over that appendix that was
 647     part of the TIFF 6.0 specification).
