I got 5 pdf files with their original dvi and ps, but i don't have the tex files which created them.
Now I would like to combine them to a single pdf. I know I can easily do it using Adobe acrobat. But it seems pdf mergers differ in efficiencies and qualities. e.g. the total size of my 5 pdf is 800kb, without any graphs. The Mac OS preview produces a combination file of size 10mb.. ridiculous. Acrobat gives 750kb which is a decent result.
So I think since I got the dvi and ps available maybe I could get better solution?
