ASDG FIRST TO OFFER JPEG IMAGE COMPRESSION FOR THE COMMODORE AMIGA
ASDG is first to bring JPEG compression technology to the Commodore
Amiga. JPEG modules to become a standard part of Art Department
Professional. Provides additional bridge linking Amiga to IBM, Apple
and other platforms.
—————————————————————————
Madison WI, August 7, 1991: —– ASDG Incorporated, a leading
provider of innovative color imaging solutions, announced today that
they have brought the revolutionary image compression technology
known as JPEG (Joint Photographic Expert Group) to the
Commodore Amiga . The ability to save and load JPEG files will
become a standard part of ASDG's Art Department Professional in its
next release.
Using JPEG comression techniques, a true color or gray scale image
can be compressed to a fraction of its original size without
significant degradation. The JPEG algorithms achieve
extraordinary compression results, potentially 80 to 1 or better.
Also, ASDG's implementation meets the JFIF standard allowing JPEG
files created on IBM, Apple or other computers to be
exchanged with those created by Art Department Professional.
ASDG's JPEG saver allows the user to specify how much compression
should take place. ASDG's JPEG loader can enhance heavily
compressed images by applying image processing techniques during
decompression. On an A3000, an overscanned (768 by 480) 24
bit-plane image, which uncompressed consumes more than 1.1
megabytes of memory, can be reduced to less than 40K in
approximately 30 seconds.
The availability of JPEG support is an important step forward as the
Amiga is so heavily used in video, print, and other imaging
related fields. JPEG's incredible compression capability means that
more images can be kept online in a managable fashion or can be more
easily transmitted from place to place.

solutions, contact them at (608) 273 – 6585.
very very nice, pk! Will eagerly look forward to Son of ADPro. Any
release date scheduled yet?

Fall.

I hope you send press releases to EVERBODY, not just Amiga magazines. I
talked to an editor at SIGGRAPH and he said they would prin print some, but
nobody ever sends them any!
We try to include non-Amiga press in our press list. Could you send us
press contacts you think we should have?

I'll get you a list of the magazines I know of and let you know.
A few questions about JPEG. As I understand it, there isn't a standard
file format yet for JPEG files, in terms of the actual bytes on a disk.
Which format are you using? I imagine it's compatible with, say, the JPEG
saver in PhotoShop? How helpful is JPEG compression when you need
loss-less compression?
John,
As I understand it, JPEG is a loss-y scheme…so there'll always be some
image degradation, even at small compression ratios. I know that at least
one of the Mac JPEG implementations allows you to select parts of an image
to receive more (or less) compression than the rest of the image. [Ugh,
bad English. <g>] If ASDG's JPEG allows this, then you may still find it
useful at times. But there'll still be some loss.

Actually, there is a standard for JPEG files called JFIF – which is stated
in our press release. I understand that PhotoShop also uses JFIF. JPEG is
lossy – you control the amount of loss which can be extremely small so as
to be entirely insignificant and yet provide compression between 10 and 20
to one. Depending on implementation, you can get compressions between 5 and
15 to 1 without loss.
Look for my article explaining JPEG internals in an upcoming AmigaWorld
Tech Journal.

How mucho are the JPEG drivers and WHEN are they available?

PS.. I'm writing my own GIF<>JPEG and wouldn't mind some help from the
PROS.
