With pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=pdflatex 2016.12.10) 10 APR 2024 19:23, and using latest TeXShop 5.31 under MacOS 12.7.4 (MacPro 2013), two jpg files were exported from Keynote, the newer jpg with Keynote 13.1 (7037.0.101).
The older jpg produced some months back works fine. A similar recent jpg (similar and in the same directory as the test tex source file), fails. This is happening with several newly produced jpgs. Ditto with png files.
Changing color profiles from Display P3 to sRGB IEC61966-2.1 did not help.
Advice will be appreciated.
