*** AOM_RAW DataType V40.2 ***
by Christian Buchner
This is a datatype for images contained on the CDs produced by
Applied Optical Media Corporation. It is loosely based on the
BMP datatype sourcecodes found in the OS 3.1 Native Developer
Kit. This datatype was originally written by David N.Junod.
All changes were done by Christian Buchner.
Installation
------------
Copy devs/Datatypes/AOM_RAW#? SYS:devs/Datatypes/
Copy classes/Datatypes/aom_raw.datatype SYS:classes/Datatypes/
Now reboot or type "AddDatatypes REFRESH" in a shell.
Introduction
------------
This datatype will load the pictures found on the following CDs
that were originally produced for Commodore's greatest flop, the
CDTV:
- American Vista Atlas
- World Vista Atlas
and perhaps some more CDs produced by Applied Optical Media
Corporation.
These pictures have a simple file structure, so I decided to
write a datatype for it. Most of these pictures are in HAM6,
some also in 32 colors.
For displaying the pictures in HAM6, you will have to tell
MultiView to use a screen because HAM6 cannot be displayed in a
workbench window for obvious reasons.
This is probably the fastest datatype ever written because there
is no decoding to be done at all. The pictures simply consist
of planar raw data with a simple header.
History
-------
Changes since V40.1:
-an awkward bug: the datatype descriptor would recognize *any*
file as AOM Raw. I must have forgotten to include the check
function when saving the descriptor.
-some minor code changes
