JAI status

[jai-interest-2]

Hi all,

I see that there are daily builds of JAI, which should indicate that JAI development keeps very active.
The thing is, when I look at the cvs reports, I notice that the only thing that is changing, from day to day, is the date.
I couldn't find any substantial change on JAI for a long period of time.

Is there anyone who can inform us about:

-The current status of JAI?

-Who is working on it's development? Is there a team? How many members?

-Since there are no changes on JAI for a long time, does it mean that it's best to use the "unstable" (daily build) version instead of the "stable", which, if I'm not wrong, was released in 2005?

I prefer Java, thus I'm using JAI, but I see that projects like, for example, OpenCV are extremely active. Why isn't JAI like that?

Finally, why isn't JAI being integrated in the standard JRE platform? I mean, don't SUN believe in the JAI project? Java 2D, Java Sound, Swing, etc. all come included.

I am not trying to criticize anybody here, I am just trying to be informed by the people that are inside this project. So, please don't be offended if something I am saying is inaccurate or seams too harsh.

Thank you very much for all your effort and work.

No need to worry about offending folks here - this is a user forum so we're all in the same boat as you.  And, at the moment, it's a boat drifting on a forgotten sea...

JAI continues to be used because, although not updated for ages, it still serves a purpose for many of us. Also if you google you'll find quite a bit of open source work that extends JAI in various ways. For instance, and at the risk of vulgar self-promotion, I'm involved in one such project: http://code.googe.com/p/jai-tools

As to the core library, it would be great to see Sun either take an interest again or open it up to open source development.  We can but hope :)

I am also looking to see if JAI is one solution to use, but also see no activity. 1.1.3 is still the latest release even though JavaOne has promised a 1.1.4 in summer 2008 (?)

Anyone on this list who might know where we a drifting towards ?

Thanx - cool product !
B-)

If there is they're keeping very quiet :)

Does 1.1.3 do what you want or are there new features, fixes, performance issues etc. that you were hoping for ?

A couple of things that would be interesting to know are:

-How stable is the daily build? Should I use it instead the stable build?
-Since the stable version is from 2005 (if I'm not wrong), what are the major differences between the stable and the latest daily version?

If nothing new is being implemented, it means that the development has stopped. I can't believe that the daily builds are just to fix errors. If someone compares OpenCV (for instance) with JAI, there are lots of operators, tools, methods, etc... that don't exist in JAI.

For example:
Image pyramids;
Morphology (you only have the 2 basic operators in JAI);
Flood fill (watershed, IFT, etc...);
Distance tranform;
Hidden Markov Models;
Active Contours;
Etc....

One could say, for example, that every other morphological operator can be implemented using the two basic operators, but I could implement those two too. I could also implement the other non-morphological operators. That way we wouldn't need an imaging library.

It would be interesting if we could send a message to Mr. Java and ask him about all this stuff, so we are not betting on something that is not evolving.

Have fun ;)

This is relevant, albeit a bit depressing...

Pardon the counter-rant ;-)...

"However, JAI also seems to be abandoned by Sun with it being moved to
the Java.net website. Specifically, Sun states that "Java Advanced
Imaging (JAI) and the associated Image I/O Tools packages are now
community source projects on java.net". This is an indirect way of
saying "we've offloaded this project to the open source community
because we are no longer interested in directly supporting this
API/framework". No direction, no future, just maintenance of existing
flaws and the odd answer to a question in the forum. This is the final
nail in the coffin. "It's dead Jim.""


This is precisely a silly and destructive attitude. By the blogger, I
mean, until more information are available. There's absolutely no sense
in declaring that if a project is no more maintained by Sun it's dead.
It depends:

1. on the precise Sun attitude - I mean, whether if they agree to
release the governance, in addition to the sources, to the community. In
particular, this involves clarifications about the licensing - JRL it's
pretty old, not an OSI approved license and I don't know whether it
allows forking
2. on the community attitude on contribute and take charge of the future
development


Because of the JRL, we need some further step and clarification from Sun
(BTW, bad timing, I suppose that the Oracle affair has frozen every
decision, and we have presumably to wait until January). But, in the
meantime, just to know, there would be somebody available to step in and
take charge of the future development, supposing we can go the
purely-FLOSS way?

You bet it's relevant.
JAI is dying. That is soooooo sad :(

I think JAI is no more, isn't it?

I think we should not have to use it for new project.
For new feature we may need to change platform.

I think no one should make Image related software like viewer in JAVA.

pls, Correct me if i am wrong.

What alternative do we have for Java server-side image processing?

I still have some hopes JAI is not definitively "dead".
As Fabrizio pointed out in a past message, the fact that JAI is no longer
maintained by Sun does not mean by itself that JAI is "dead".

Now JAI is on java.net and it is open to contributions by users.
There are of course some important missing points which should be modified /
clarified / improved in order to be able to rely on JAI for future projects
in my opinion:

1 - Availability of sources for the native portion of JAI and JIIO. It is
absolutely "non-sense" today not having native codecs for Windows 64-bit
platforms, for instance. Or not having native libs at all for the Mac
platform! These are BIG problems at the moment with using JAI / JIIO for
some kinds of applications.

2 - Project governance

3 - Contributions by the developers community

4 - Licensing issues

In general, I would NOT say Java is absolutely unsuitable for imaging
software. There are a lot of excellent Java-based imaging software out
there.
I agree on the fact that Sun is not giving the feeling of having definite
programs / ideas about how to evolve some multimedia-related Java APIs, such
as JAI, JIIO, JMF, Java3D, etc., and this is worring me a bit: these APIs
have a great potential in my opinion...

Just my 2 cents...

Greetings,

Marco.
