I am trying to improve storage efficiency for PDF files in a git repo. Following earlier discussions in this list I am trying to set up proper clean/smudge filters. What follows is my current setup # in ~/.gitconfig [filter "pdf"] clean = "pdftk - output - uncompress" smudge = "pdftk - output - compress" # in .gitattributes *.pdf filter=pdf Unfortunately, it seems as though that pdftk uncompress followed by pdftk compress do not leave the file invariant. I tried several uncompress+compress iterations and the file still keep changing (the size though stays the same). Is there any other alternative way to store PDF files in git repo more efficiently? Any alternative to pdftk on Linux? --Leo-- -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
