jpeg 2000

[Harm Olthof]

Can anyone point me to a jpeg2000 package/extension for reading and writing
Tk images?

Thanks,
Harm

I know of none, but it should be possible to extend tkimg to support the
JPEG 2000 format using OpenJPEG <URL:http://www.openjpeg.org/> as a
basis library on the grounds that it has a compatible license. If you
want this, file a feature request for tkimg at
<URL:https://sourceforge.net/tracker/?func=add&group_id=52039&atid=465495>
though I have some minor technical concerns (the documentation isn't
good and C++ is still tricky in portability terms).

It should be noted that there may be patent problems with JPEG 2000
(submarine patent scum being what they are). Because of this, we
*definitely* would want someone else to be primarily exposed and so
there's definitely not going to be any effort to develop a JP2 library
ourselves.

Correction: it's not C++. Doxygen managed to fool me. :-}

Hello Donal,
Thanks for the suggestion and looking into the license and patent issues of
OpenJPEG.
Meanwhile I submitted the feature request....

Regards,
Harm

Depending on your platform, you could also try my QuickTimeTcl
package.
Seems it is there but I never tried it:

Thanks, I will try that as well. Nice to see there's an intro in
Dutch!
