Hello,

I'm trying to find out if Firefox can render JPEG2000s using its own
good self, or whether it needs help from something like QuickTime.

Does anyone have an idea how I can find out?

Can't find any reference to the matter on-line.

Cheers,
Rowland.

Well, they certainly added the code for it here:
<http://dltj.org/article/j2k-in-gsoc-2007/>

but I don't know if it worked, as my copy of firefox can't seem to open
jpeg2000s I find on the web. Mind you, I could only find a couple of
jpeg2000s on the web.

Aha! So how is it you manage to track this stuff down? What searching
did you do? I'd like to learn...

Care to provide a link or two? - and how might one use Google (or
whatever search engine) to search for a particular file type like jp2?
I've tried and failed.

Got lots of stuff *about* JPEG2000s, but can't seem to hit on a jp2 file
as such.

My copy of Firefox opens all the JPEG2000s that I've created with
Graphic Converter.

I typed 'jpeg2000 firefox' in google, and it is one of the results.
having said that, I didn't go straight to it, but went to one of the
other links, which was a discussion about it.

I tried searching on the mozilla firefox site but there was nothing of
any use there.

Although I just thought about it, and typed "jpeg2000 site:mozilla.org"
in and found a couple of other things.

this: <https://bugzilla.mozilla.org/show_bug.cgi?id=36351> shows the
history of whether to support it or not.

well, there are some connected to here:

<http://www.codinghorror.com/blog/2007/02/beyond-jpeg.html>
neither safari or firefox can open:
<http://www.codinghorror.com/blog/images/lena512color-50.jp2>


But the easiest way is just to search google for "filetype:jp2"

Hmm.. maybe there are different subtypes that work.

this one <http://www.aadmm.de/images/gf6.jp2> seems to work in
everything

Hmm. Obvious - so why didn't I think to do that?

Righto.

Me too.

Ah - I wouldn't have thought of that.

Are you sure? I can't see any links to any actual JPEG200 files - see
below.

<puzzled>

I looked at that Web page - according to Firefox, it's a short HTML text
file looking like this:

<html><head>
<meta http-equiv="content-type" content="text/html;
charset=UTF-8"></head><body></body></html>

Firefox opened it *fine*...

According to DeepVacuum, it doesn't exist:

Righto - I had no idea that was possible. Umm. How do I search Google
for filetype:jp2?

I tried

filetype:jp2

in the Google search box, and it just came up with a bunch of hits based
on I don't know what, but no jp2000s that I could see. I gave up after
a bit - most of the pages required Javascript to be executed, and are
also far too foreign for me to figure out anything at all about 'em.

I suspect that you've just not found many actual jpeg2000s to look at
with Firefox.

Erm - any idea why that page needs a javascript to execute just to
display one small image?
