Program information
-------------------
akGIF.datatype is a GIF datatype, which supports GIF87a/89a and
handles transparency along with tiled images - the latter either
as multiple frames (single pictures instead of an animation),
8 bit "mosaic" (if same palette for all tiles) or 24 bit "mosaic"
(if different palette for some tiles - this results in a so-called
"true-color GIF").
It does support interlaced GIF (note: it reads interlaced GIF, but
DataTypes cannot display images progressively - instead only as a
single chunk). The same restrictions apply to tiled images.
WARNING: if the pic-dt of your OS version does not support alpha channel
handling, then always set TRANSTOALPHA=OFF (no ARGB/RGBA)
--------------------------------------------------------------------------
You should use the included preferences program for best configuration.
See program archive for copyright and distribution information.
**************************************************************************
V45.87 (16.1.2008): - fixed version/date strings for V45.86
- for tiled images now also other types
of transparency/alpha are supported:
- 24 bit GIF (multi-palette) tiles
single/multi color transparency becomes
32 bit ARGB/RGBA
- 8 bit GIF multi color transparency
becomes 32 bit ARGB/RGBA in case
TRANSTOALPHA is set (otherwise ignored,
since it is not clear which of the
different transparent colors should
be made transparent in the single
color 8 bit case)
- added STRIPALPHA option
- fixed minor mem-leak related to extra
buffers for alpha and alpha-mapped
transparency
- fixed newly introduced race condition
- avoid multiple level 2 buffering setup
- fixed the viewmode fix from V45.86
a second time
- MOS: switched compiler (same as SV5)
and enabled optimizer
V45.86 (5.1.2008): - fixed bug in TRANSTOALPHA (oops)
- fixed long-standing MOS bug in viewmode
generation routine (did not occur with 68k
and did only pop up with some graphics)
V45.85 (4.1.2008): - MOS/68k: now really building from same
source tree; the following
information is relative to
the former MOS tree
- improved MOS startup code
- added TRANSTOALPHA and SWAPALPHA options
- documented all prefs settings again
- Prefs: made the labels easier to understand,
especially the 24 bit / tile settings
V45.84 (2.1.2008): - some additions to asyncio routines
- improvements in asyncio routines
V45.83 (28.12.2007): - fixed bug in asyncio dispatcher, which
could have lead to a stale file lock,
thus memory loss, in case of DOS fallback
during AsyncIO availability
