 Program information
 -------------------
 akTIFF.datatype is a TIFF datatype, which is based on the
 TIFF reference sources (libtiff 3.8.2).

 It does support 8 Bit color mapped files (colorspace expanded to
 8 bit per component always) and True color files (24/48 Bit, alpha
 channel supported, 48 Bit 16:16:16 cut down to 24 Bit 8:8:8).
 All important compression types supported. Exotic colorspaces
 imported AS-IS and converted to RGBA, unless directly supported.

 [ More detailed description can be found in akTIFF.guide ]

 WARNING: if the pic-dt of your OS version does not support alpha channel
          handling, then always set STRIPALPHA=ON (no ARGB/RGBA)

 --------------------------------------------------------------------------

 You should use the included preferences program for best configuration.

**************************************************************************

 V45.92 (25.3.2008):   - fixed NULL pointer issue which did
                         not occur under MOS (with 24/32 bit)
                         (-> Thomas Klein)

 V45.91 (15.3.2008):   - debug mode now more verbose
                       - added real error handler
                       - internal TIFF decoder now also
                         handles multi-page files

 V45.90 (5.2.2008):    - ARGB32 still was not fully fixed
                       - added missing alpha support in
                         internal 32 bit "uncompressed" decoder
                       - fully rebuilt DT code

 V45.89 (27.1.2008):   - updated TestDTAlpha tool and check for
                         PICDTALPHA
                       - memory consumption for ARGB32 was
                         much too high (typo in allocation);
                         there now is a less costly fallback
                         for low-memory situations
