To clarify, the CreationDate and ModDate headers vary, but that is an separate issue. For example, in: http://i.imgur.com/GU5lqxF.png .. I am ignoring the top part of the diff. > less pictures and no tableofcontent and afterwards the pdf was reprocubile. I can actually reproduce with the following: \documentclass{article} \begin{document} \tableofcontents \end{document} NB. no images, no graphicx, etc. This makes the PDF (again, modulo {Creation,Mod}Date headers) reproducible within the same second, which suggests a time-based random seed generation. (There is one in web2c/pdftexdir/pdftex.web which makes me suspicious.) > One workaround is to use optipng for all input pngs, that made the pdf > also reproducible. .. which somewhat contradicts my previous paragraph. We might have three issues here instead of just two. Regards, -- ,''`. : :' : Chris Lamb `. `'` la...@debian.org / chris-lamb.co.uk `-
