When uploading a large image (16667x5000) I get this error:

Quote

width or height exceeds limit `.../site/assets/cache/WireTempDir/.PFM0.87481800T1615895885RN5Ct513qCVbti/0/zeitung_inserat_jpg_ac_adrian_cirita_fruehl_2021.0x260.jpg' @ error/cache.c/OpenPixelCache/3911

This happens after the 7MB image is uploaded. I'm using ImageSizerImagick and have 512MB memory setting. I have tried to set client side resizing to max 1920x1920 but then it gets stuck before upload.

Has anybody of you ever experienced something similar? Any ideas how to solve that? Manually resizing the Image before upload is of course a solution, but not the best one...

Maybe @horst ?

Image Magick has a policy.xml file somewhere in /etc where its default limits are configured - usually quite permissive, but different distributions may ship their own limits for maximum image width / height, memory limit, map (disk cache) limit etc. as explained here https://www.imagemagick.org/script/security-policy.php. I have no idea if/how these policies are honored when called from PHP, but it might be worth taking a look.

There have been some stricter settings in general in the policy.xml in recent versions of Imagemagick, some to protect against ghostscript vulnerabilities (https://askubuntu.com/questions/1127260/imagemagick-convert-not-allowed) so it's probably a good time to get familiar with policy.xml (https://imagemagick.org/script/security-policy.php), although I must admit I have starting using command line tools for PDF stuff lately, eg: pdftoppm and pdfinfo - sorry, getting OT.
