I was told to report it here by KDE developers. KDE bug: http://bugs.kde.org/show_bug.cgi?id=212298. Poppler version: poppler-0.12.1-2mdv2010.0. Screenshot: https://bugs.kde.org/attachment.cgi?id=37952 Look at attached screen shot. The main document text appears very blurry comparing with anything else on the screen. Actually it literally strains my eyes to read it. I am happy to provide any additional information; I'm just not exactly sure which one.
The rendering doesn't look bad to me. It looks properly antialiased, which increases blurriness, but also increases readability, as it avoids unnecessarily jagged edges. Can you provide a competing screenshot from another utility that does a better job with the font rendering, and then reopen the bug? Otherwise, I think this is a "won't fix".
Hi Joshua, thanks for your opinion, but since you are not part of the poppler team (yet) i'm reopening the bug.
I see that text outside poppler is rendered with sub-pixel rendering while the text inside poppler is not. Is this buggy? Anyway, one has to take into account that Computer Modern (the font used in the pdf) maybe doesn't contain any hinting, and is not designed for screen display anyway.
I think Yi Yang nailed the issue. For example, contents in Evince are not affected by GNOME Tweak Tool's font "antialiasing" setting (neither by the "hinting" setting). If I change those settings, the font rendering of everything changes, except Evince's contents area. FWIW, I'm using Evince version 3.10 with poppler+cairo 0.24.3. As I'm suspecting, the poppler cairo backend (unlike the "splash" backend?) does not support hinting, right?
