Version:  44.6
Type:     util/dtype
Requires: OS 3.0+,picture.datatype v43+

Changes since previous release:

 - Fixed TIFF descriptor file - no longer mistakes MED modules as TIFFs :)
 - Images in 12-bit (or less) RGB format are now decoded correctly.


FEATURES

 - Supports 5.0 and 6.0 TIFF spec, including Packbits, Thunderscan,
   CCITT (fax), Pixar, LogLuv (CIE and SGILog) and Deflate (zip)
   encodings, and uncompressed files.  LZW and JPEG encodings are
   currently unsupported

 - Image types supported include RGB (24-bit and 48-bit), palette based
   and greyscale (1-bit, 4-bit, 8-bit and 16-bit)

 - Supports image data organized as strips, tiles or separate components

 - For multi-image files, applications may choose which picture to decode

 - Scaling options for high resolution fax images

 - Highly optimized datatype dispatch engine, and fast TIFF decoder,
   resulting in a very efficient, compact and quick TIFF datatype

 - Asynchronous file i/o and double buffering techniques (WarpOS only),
   which speeds up image decoding
 
 - Optimized versions for 68020, 030, 040 and 060

 - PowerPC support with native WarpOS and native MorphOS versions

 - Alter the pen allocation precision when images are remapped to an
   8-bit display

 - Specific support for the OS 3.5/3.9 picture.datatype, when available

 - The dithering feature of the OS 3.5/3.9 picture.datatype can be
   configured to your liking (e.g. disabled for 15/16-bit displays)

 - Based on libtiff 3.5.6-beta and zlib 1.1.3
