akJFIF.datatype manual V43.5 (20.10.96)
(C) 1996 by Andreas R. Kleinert.
All rights reserved.
Usage
-----
Just install the datatype files to their appropriate directories,
and copy the akJFIFPrefs command to SYS:Prefs (optionally).
Please make sure, that there is a directory available, where temporary
data can be stored. There must be an assignment called "VMEM:" to
this directory.
The assignment originally would have been "JPEGTMP:" for the JFIF
sources, but the memory manager has been strongly modified and
enhanced - on a system with many RAM available you will perhaps
never actually encounter usage of that directory.
Do not assign it to "T:" - just create a safe place for it.
Program information
-------------------
akJFIF.datatype is a new JPEG datatype, which is based on the
latest IJG JFIF sources V6a.
So it does support progressive JPEG and all the other things
introduced with V6a (note: it reads progressive JPEG, but DataTypes
cannot display images progressively - instead only as a single chunk).
With V39-V42 picture.datatype it produces 256 color palette-based
(with either none, floyd-steinberg or ordered dithering) or HAM6/8
output, with Ralph Schmidt's picture.datatype V43 as well optionally
24 Bit output may be done.
You must use the included preferences program for best configuration.
akJFIF.datatype is SHAREWARE, the future depends on YOU (-> see README).
