ImageMagick is missing JPEG2000 support (needs to be built with openjpeg)

Also affects XENIAL.

I tried compiling from source: Resulting binary: no JP2 support.

Then I installed "libopenjp2-dev" and built again. Now I do have jp2 support.

So the problem is that the imagmagick upstream releas has switched to prefer libopenjp2 instead of libjasper, while the ubuntu build procedure lists libjasper-dev as a build requirement instead of libopenjp2.

Add me to the list for whom this is annoying. ImageMagick switch from libjasper to libopenjp2 two years ago, and the Debian upstream packages was fixed a year ago, so why is this not fixed on Ubuntu yet?

The reason this has not been fixed is because imagemagick is in main, so all of its build-deps must be in main. openjpeg2 is not in main so that needs to get put in main first.

There is a main inclusion request in bug 711061, so hopefully we can see this fixed in the future.

Is there a workaround that will get JP2 support working?

Hi. Are there any updates to ImageMagick JP2 support? Thanks!

Looks like bug #711061 is still blocking it

2019-06-27: just tired to install "imagemagick" on a fresh 18.04.2 LTS, still no JP2 support.

Any particular reason why imagemagick needs to stay in main, given that this seems to hinder the capabilities of this package by not letting it link against openjpeg2? That is: rather than waiting for openjpeg2 to be included in main, cannot imagemagick be taken out of main?

Alternatively, can a more capable imagemagick be made available out of main with proper conflict to the imagemagick in main?

openjpeg2 was promoted to main in bug #711061, so this could be enabled now like it was in Debian.

Could we please get some action on this now that it has been promoted? :)

Ok, I came across this open thread thinking that it was abandoned (it's from 2015!), but apparently there have been a few messages in the past few days, so at least I know I'm not insane... as the OP said, I was assuming that IM on Ubuntu (even on my old 16.04.6 LTS Xenial) came with the JP2 coder built-in, and, indeed, I *thought* that this was the case:

# convert -list coder | grep JP2
J2C JP2
J2K JP2
JPC JP2
JPM JP2
JPT JP2
JPX JP2
PGX JP2

But clearly this is *not* true, since on ImageMagick 6.8.9-9 Q16 x86_64 built in 2019-11-12 I get:

Delegates: bzlib cairo djvu fftw fontconfig freetype jbig jng jpeg lcms lqr ltdl lzma openexr pangocairo png rsvg tiff wmf x xml zlib

(well, I have added a lot of stuff, thus Cairo etc. are listed)

I also have installed *both* jasper (lib and runtime) as well as libopenjp2-7 (and libopenjpeg-dev & libjpeg62-dev & openjpeg-tools for good measure...).

I'm not really familiar with IM — I thought, for instance, that you could just tweak the .xml files and get 'instant' results without needing to recompile it — so I guess that my only choice is to install IM from the sources to get JPEG-2000 support?... I have little faith that, after 5 years, there are still developers with free time and willingness to 'fix' this bug, especially because I can very well imagine that the latest Ubuntu versions have fixed this somehow...

There *is* a PPA listing imagemagick-jp2 which *does* have working JPEG-2000 support, but they haven't applied the latest security patches...

This bug was fixed in the package imagemagick - 8:6.9.10.23+dfsg-2.1ubuntu12

  * Build depend on libopenjp2-7-dev as that is in main. (LP: #1447968)

Aw. No fix for focal?... Anyway, I hope that groovy bumps ImageMagick to 7 like all other Linux distributions out there (as well as macOS via Homebrew and FreeBSD). After all, IM 7 has been around since April 2016, it's very mature code these days, after 227 releases (as of the date of writing), and it seems sort of strange why it has not been supported under Ubuntu...

It is April 2024 and I am having trouble getting ImageMagick to convert JP2 files. Has this problem really been fixed or is just broken again? I don't see jp2 or J2K listed in the delegates.

 PHP Fatal error: Uncaught ImagickException: no decode delegate for this image format `J2K' @ error/constitute.c/ReadImage/572 in /home/eric/convert-test.php:7

All I can say is that on Ubuntu 22.04.4 LTS (jammy) I (still) don't get IM 7 yet — most likely because it's not due for release in a LTS distro? — and I'm still stuck with 6.9.11.60.

Since for a few package I *need* IM 7 (namely, PHP from Ondrej's repository (https://ppa.launchpadcontent.net/ondrej/php/ubuntu/), I have compiled it from scratch (what else could I do?...).

Naturally enough, JPEG2000 support — which I desperately need as well! — works flawlessly:

@eamitchell, your version actually seems very weird to me — not even PNG support??

Eric, this issue was fixed after Ubuntu 20.04 LTS "focal". I encourage you to upgrade to Ubuntu 22.04 LTS.

In general, it is better to open new issues than comment on issues that are marked Fix Released because people may not see your comments.
