Short:        New Datatype for JPEG Images (43.6a)
Author:       achimste@gmx.de (Achim Stegemann)
Uploader:     achimste gmx de (Achim Stegemann)
Type:         util/dtype
Version:      43.6a
Architecture: m68k-amigaos; ppc-warpup

Requires minimum:
 * OS 3.0
 * MC68020

Additionally recommended:
 * CyberGraphX with picture.datatype V43 for 24-bit images.
 * MUI 3.8 for the preferences.

If you run OS 3.5 or OS 3.9, it is recommended to install the JPEG-DT35 archive !!

With the help of the jpeg.datatype, your datatype sytem is able to read JPEG images.

This datatype is freeware and can be used for any purpose !


##### Why another datatype for JPEG images ? #####

Well there are many of them available on the Aminet, but this has two unbeatable
advantages !!

1. It is very short, only about 8 kB !! Why ? Because it does not contain the JPEG
de/encoder and color quantizer in the datatype itself.
The datatype uses the jpeg.library from Paul Huxham for the JPEG de/encoding and the
render.library by Tim Müller for color reduction. The jpeg.library has been developed
from the latest JPEG V6b release, so it is up-to-date.

2. It can write JPEG files when using the DTMW_RAW flag in the DTM_WRITE method !!
The V45 of datatypes by Roland Mainz is supported, so you can convert any datatype
picture to JPEG.


#### Note ####

If you have another jpeg.datatype (with THIS name) installed on your Amiga with a
version number higher than 43.0, the installer will not be able to replace it.
In this case, you must copy the jpeg.datatype manually to your SYS:Classes/DataTypes
directory.

Changes since V43.6:
* Fixed a bug in the installer script. Wrong CPU version of render.library was copied.

Changes since V43.5:
* Cleaned up ramlib-stuff (thx to Oliver Roberts).
  jpeg.library (WarpOS version) works again with datatype, no crash with IPrefs :)
