Description Bernd Oliver Sünderhauf 2009-03-10 05:34:43 UTC
Version:            (using KDE 4.2.1)
OS:                Linux
Installed from:    Ubuntu Packages

I'm attaching three files where the fonts are incorrectly rendered in Okular, whereas they're correctly rendered in Acroread, Evince and even in the Dolphin previews. Please take a look at the attaced files.

Note that the test files were created using iText. It is rather unlikely that the error is on iText's side, because all three files render correctly in other PDF viewers.

Hi,

Okular does not load and render PDF documents on its own, but uses a 3rd party library called "Poppler".
Please report the problem at the Poppler's bug tracking system at https://bugs.freedesktop.org, "poppler" product.

Thanks for your report.

Hi Pino!
I know that Poppler is Okular's PDF rendering backend, and would have filed the bug there.
However I'm assuming that Dolphin's PDF preview uses Poppler as well and I know that Evince does use Poppler. Still, both render the files correctly.
So I'm not really convinced that it is a Poppler bug, and leave the ticket here in the Okular tracker.

Unfortunately I'm not familiar with Poppler's nor Okular's interfaces, so I can't tell what could possibly cause the error on Okular's side. Hopefully someone else can step in for me at this point.

Regards, Pancho

Wrong assumption, it uses Ghostscript.

As I said, this is a Poppler bug.
