15*0ef31e1fSMike WellesThe library is capable of dealing with images that are written to
16*0ef31e1fSMike Wellesfollow the 5.0 or 6.0 TIFF spec.  There is also considerable support
17*0ef31e1fSMike Wellesfor some of the more esoteric portions of the 6.0 TIFF spec.

641*0ef31e1fSMike WellesThe <TT>Matteing</TT> and <TT>DataType</TT>
642*0ef31e1fSMike Wellestags have been obsoleted by the 6.0
643*0ef31e1fSMike Welles<TT>ExtraSamples</TT> and <TT>SampleFormat</TT> tags.
644*0ef31e1fSMike WellesConsult the documentation on the
645*0ef31e1fSMike Welles<TT>ExtraSamples</TT> tag and Associated Alpha for elaboration.  Note however
646*0ef31e1fSMike Wellesthat if you use Associated Alpha, you are expected to save data that is
647*0ef31e1fSMike Wellespre-multipled by Alpha.  If this means nothing to you, check out
648*0ef31e1fSMike WellesPorter & Duff's paper in the '84 SIGGRAPH proceedings: "Compositing Digital

652*0ef31e1fSMike WellesThe <TT>ImageDepth</TT>
653*0ef31e1fSMike Wellestag is a non-standard, but registered tag that specifies
654*0ef31e1fSMike Wellesthe Z-dimension of volumetric data.  The combination of <TT>ImageWidth</TT>,
655*0ef31e1fSMike Welles<TT>ImageLength</TT>, and <TT>ImageDepth</TT>,
656*0ef31e1fSMike Wellesdefines a 3D volume of pixels that are
657*0ef31e1fSMike Wellesfurther specified by <TT>BitsPerSample</TT> and
658*0ef31e1fSMike Welles<TT>SamplesPerPixel</TT>.  The <TT>TileDepth</TT>
659*0ef31e1fSMike Wellestag (also non-standard, but registered) can be used to specified a
660*0ef31e1fSMike Wellessubvolume "tiling" of a volume of data.

663*0ef31e1fSMike WellesThe Colorimetry, and CMYK tags are additions that appear in TIFF 6.0.
