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):
Hi Jim,
using your image (SHA512 2087e6b338a0f99b1fd3c1b987eabc246b97d0508f69afdcddcc947caa1fc3eea1e7a8e166825700659ffc2c7500a1e746deceee8df24d978f7849602fa69eef) with both ConTeXt 2025.02.28 18:16 and either LuaTeX 1.21 7667 or 2.11.07 20250226 gets the right image displayed on the page.
I’m on Fedora Linux, so Linux might not be the problem here.
Well, I'm a bit boggled as to what the problem might be. As you might have seen in my reply to Bruce, I tried an MX-Linux VM and that has the same issue.
Would it be possible that your PDF viewer or dependent libraries might have an issue with these kind of images?
No, the issue does not seem to be the viewers. It is not like there is a blank spot where the image is, instead I see the grey box that context puts in when it can't find or read or ... an image that you asked for. Also, just for completeness, xpdf, evince, whatever AucTeX uses in PDFview, and my venerable Adobe acroread only show the grey box. Whereas, xpdf, evince and acroread all show the JPEG2000 images when I run the context from texlive 2024.
On my computer, either Evince/Okular (both poppler-based), or MuPDF-GL, or MuPDF.js (from current Firefox) display both images right fine.
My (educated?) guess is that this might be an issue with your viewer.
Thanks, but that seems very unlikely to me. Especially since all my viewers were working fine before I upgraded by stand-alone context to the 2025.02.28 version. It seems unlikely they would all stop working because of that.
At least, test your result with a different PDF viewer.
Just in case it might help,
Thanks. But sadly, that does not appear to be the issue. Cheers. Jim
