(In reply to comment #0) > Latex/PDFLatex generated documents are much less readeable in okular, compared > to KPDF, even with both using the same version of poppler. KPDF does not use poppler. And if it does, your distro is responsible for it, but it isn't what was developed by KDE. > I'll provide a > screenshot with PDF documents and Adobe Reader for comparison.

Please report the rendering issues to the Poppler's bug tracking system at https://bugs.freedesktop.org, "poppler" product. Yet, okular must use poppler in a different way than KPDF does, since as noted above, there are serious differences in visual quality between both, although both are using exactly the same version of poppler. I don't know their code, so are you absolutely sure this is not caused by how poppler is used in each of these applications? Do you know other QT PDF viewers to check whether the QT 4 bindings are the problem?

KPDF's xpdf code is comparable to xpdf 3.02, or poppler 0.5 (super-old). > I don't know their code, so are you absolutely sure this is not caused by > how poppler is used in each of these applications? Okular just asks Poppler to render pages as images, that's it. (In reply to comment #3) Sorry, I overlooked part of your comment. KPDF can be compiled with the option --with-poppler, which is the default for my distro. #6, no, that option does not exist in KPDF, might exist in your distro, but still it's not real KPDF Dangit! It's a kdegraphics option, but apparently not affecting kpdf. Thank you for your help and patience! Let's mark this invalid, then. Created attachment 34467 [details]
Comparison of the same DVI document viewed in KDVI and Okular
Now unfortunately, there is no external library used for rendering DVI documents. As it seems, the code of kdvi/xdvi has been recycled. If that is true, something might have gone wrong ... the same loss in readability and visial quality appears with DVI files as well: thin lines tend to disappear, thick lines tend to dominate. I initially mentioned this, but I did not provide a screenshot for it yet, so here it comes. Where does this problem belong? Please send me on or reopen.
Are you sure the right is a dvi? The fact that title says dvi doesn't mean anything as title is got from the file. Yes I am, it's vanilla Latex output. Reopening then, please attach the dvi file. Created attachment 34580 [details]
The presented DVI file
This DVI file was generated using texlive 2008.
I can confirm that using poppler 0.12 this bug is finally fixed. See also http://bjacob.livejournal.com/10641.html Given #14, should this bug remain open? Carsten: Can you still reproduce? Not reproducible with my current setup. Qt: 4.7.2 KDE: 4.6.5 (4.6.5) Okular: 0.12.5 poppler: 0.16.7 Marking resolved/fixed, if you're ok with that. |
