--- Comment #5 from tovrstra <[email protected]> --- Reproducibility seems indeed not possible at this stage. I've attached an example to show that there is more going on than just different time stamps. Steps to reproduce the example: 1. Export slide.odp to PDF twice. 2. Decompress streams in the two PDFs with ` mutool clean -d slide1.pdf tmp1.pdf mutool clean -d slide2.pdf tmp2.pdf 3. Generate diff html with vim: vimdiff tmp1.pdf tmp2.pdf -c TOhtml -c 'w! diff.html' -c 'qa!' There are four points where the PDFs differ: - A binary stream (length is also different). - xmp:CreateDate tag. - /CreationDate field. - PDF Trailer ID, which is just a random blob. As far as I understand, random trailer IDs are sometimes useful for document tracking, but they are not critical. It would be helpful to have an option to create reproducible PDFs, e.g. with a command-line option, or to disable all variable parts when SOURCE_DATE_EPOCH is set. -- You are receiving this mail because: You are the assignee for the bug.
