[NTG-context] Re: Problem with JPEG2000 inclusion in 2025.02.28 update

Hi Jim, it works here with your cow-jp2.jp2 without problems with: ┌──(userland㉿localhost)-[~] └─$ context --version mtx-context | ConTeXt Process Management 1.06 mtx-context | mtx-context | main context file: /home/userland/lmtx/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2025.02.28 18:16 mtx-context | main context file: /home/userland/lmtx/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2025.02.28 18:16 on: ┌──(userland㉿localhost)-[~] └─$ uname -a Linux localhost 6.1.93-android14-11 #1 SMP PREEMPT Thu Feb 13 06:09:31 UTC 2025 aarch64 GNU/Linux Greetings Lutz Am 22.

I use JPEG2000 images and, unit the most recent update, these worked fine for me (i.e., anywhere a "normal" JPEG could be included, a JPEG2000 could be included).

This seems to have come to a crashing halt with the 2025.02.28 update. Now I just get the gray box. Here is an example of it not working (I have attached a .JP2 image of ConTeXt's favourite cow):

Which OS are you using

I am using Linux (specifically, Slackware64 15.0).

because I have no problem displaying sample1.jp2 from https://toolsfairy.com/image-test/sample-jp2-files on a Mac using 2025.02.28.

I downloaded and tried sample-jp2-files-sample1.jp2 from that web site, and it also does not show up using the most recent context.

(Just out of curiosity, did you try the cow-jp2.jp2 I attached to my original email?)

I have TL2024 and TL2025 installed on my my system. The context in TL2025 is also the 2025.02.28 version, and it also doesn't work.

Contrariwise, the context in TL (2024.02.27) does show .JP2 and .JPX images.

While I could use the context from TL2024 to include JPX files, the TL2024 context breaks paragraphs differently than more recent versions, and is missing some other things which I depend upon.

Thus my interest in either getting the JP2/JPX inclusion (on Linux) fixed, or backing up to whatever version preceded 2025.02.28.

Cheers. Jim
