Hi Karl, > Libpng was updated during the year (thanks to Akira), as usual. We > currently have 1.6.54. I wonder if that can be related to the change in > behavior. pdftex itself certainly didn't change wrt png's. -k There is no real change of behavior, just that I try to deal with "funny scientists" uploading 10000x7000 px images to be includes into their LaTeX document, and libpng decides it needs to reencode them for PDF due to (alpha channel|whatever chunk in png) and this takes ... takes .. ages. Exmaple: One run without compatible images: 3min30, with compatible images: 5sec (!)
