Missing fonts #21

Closed Zlopez closed 5 years ago

Zlopez commented 5 years ago

I tried to open a document and none of the fonts was available in the flatpak, so I end up with unreadable text. It's possible to read them from some runtime?

Your unreadable example looks like an encoding issue not a font issue.

This PDF doesn't have embeded fonts, but it's correctly displayed in gmail web interface. So I think this is issue with fonts, otherwise this issue will be same in every other PDF reader.

That is faulty logic. The characters are rendered just the wrong ones which is an encoding issue, otherwise they would show as the missing font character. That isn't to say it isn't an Evince bug.

Zlopez commented 5 years ago

Ok, in this case where should I fill the bug?

It could be a problem with poppler, the library evince uses for PDF rendering. Try it with poppler's pdftocairo program, such as pdftocairo -png input.pdf output, and if it's the same bad rendering, file a bug at https://gitlab.freedesktop.org/poppler/poppler/issues/new?issue .

@jascrain Thanks, I tried the pdftocairo and got different bad rendering, but still it was rendered badly. So I created an issue in poppler. I hope this will be useful.

Closing this issue, as it belongs to Poppler.
