One reason I suggested exploding/recompressing is that by doing so, you will naturally destroy lots of metadata that you might not have realised was there, otherwise.

One of the advantages of using pdfparanoia is that you can directly remove watermarks based on what we know about what publishers are doing, instead of blindly guessing. If there is metadata about ip addresses, write a plugin for pdfparanoia to detect it and remove it. (Also write a unit test, so that future contributors can make sure your code doesn't break). So far, I haven't seen evidence of metadata being used like this. Really, they are all extremely pdf servers like itext that are serving up http requests for unsuspecting scholars. My guess is that the most "advanced" watermarking infrastructure is just some LaTeX template that is being applied for each incoming http request. - Bryan http://heybryan.org/ 1 512 203 0507 -- -- You received this message because you are subscribed to the Google Groups DIYbio group.
