Yes, I also had a similar idea of how does it work. > > The reason of my question is that there are several pdf viewers in the > > repository based on poppler.

Old looking, perhaps, but thats due to its > use of lesstif, right? Or did you mean anything else? Well, I mean that it has been around for quite a while. I think I have been using it since at least 10 years ago. > * What do you mean by "slow"? In most cases, I think that it is, at > least, of the same speed as others, even if using poppler. Currently scrolling in xpdf is visually slower than in evince (yes, I know about that compiler-related bug #577031: I am using a version which is not affected). > I have not yet benchmarked the differences between "pure" xpdf and > xpdf+poppler, but I would say that they are very minor. Then the diffrence in scrolling between evince and xpdf is probably only because xpdf renders "by parts". -- Stanislav -- To UNSUBSCRIBE, email to debian-mentors-requ...@lists.debian.org with a subject of "unsubscribe".
