Changes since previous Aminet release:

 - Updated with libtiff 4.4.0, zlib 1.2.12 and jpeglib 9e.
 - Added support for reading tiled planar RGB/CMYK images.
 - Faster decoding of LZW encoded images and some others.
 - Disabled asynchronous i/o when loading images via OS4 vector-port
   filesystems, removing overhead to improve performance (still enabled
   for older filesystems such as FFS2 and SFS).
 - OS4 version recompiled with GCC 11.2.0.
 - MorphOS and WarpOS versions recompiled with VBCC 0.9h.
 - Tweaked version string so that CPU information can be viewed with
   the version command.
 - Benchmarks now performed using PicDTBench.


FEATURES

 - Supports 5.0 and 6.0 TIFF and BigTIFF specification files, including
   those using Packbits, Thunderscan, CCITT (fax), Pixar, LogLuv (CIE and
   SGILog), LZW, Deflate (zip), JBIG and JPEG (old and new) compression
   schemes, plus uncompressed files

 - Image types supported include RGB (24-bit, 48-bit, 96-bit and 192-bit)
   with or without alpha channel, palette based / greyscale (1-bit,
   2-bit, 4-bit, 8-bit, 16-bit, 32-bit and 64-bit), CMYK (32-bit, 64-bit
   and 256-bit), YCbCr and CIELab

 - Can handle Xerox / ScanSoft Pagis XIF files (eXtended Image Format)

 - 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 OS4, WarpOS and MorphOS versions

 - AltiVec speed optimizations (JPEG decompression) for OS4 and MorphOS

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

 - Specific support for the AmigaOS picture.datatype v44+, when available

 - The dithering feature of the AmigaOS picture.datatype v44+ can be
   configured to your liking (e.g. disabled for 15/16-bit displays)

 - Based on libtiff 4.4.0, zlib 1.2.12, jpeglib 9e/6b and libjpeg-turbo


REQUIREMENTS

WarpTIFF is a TIFF datatype which utilizes and requires the following:

 68k version

 - Kickstart 3.0 or higher
 - 68020 processor or higher (optimized versions included)
 - picture.datatype v43 or higher
   (supplied with AmigaOS 3.1.4, 3.2, 3.5, 3.9, CyberGraphX, P96 or AfA OS)

 WarpOS version

 - Kickstart 3.0 or higher
 - PPC accelerator card + 68040/060
 - WarpUp Release 5.0 or higher
 - picture.datatype v43 or higher
   (supplied with AmigaOS 3.1.4, 3.2, 3.5, 3.9, CyberGraphX, P96 or AfA OS)

 OS4 version

 - PPC accelerator card / AmigaOne / SAM
 - AmigaOS 4.0 or higher

 MorphOS version

 - PPC accelerator card / Pegasos / Efika
 - MorphOS 1.4 or higher

Note that a graphics card is not necessary.
