Description digulla 2009-05-10 11:33:47 UTC
The kerning of text in OO on Linux is very uneven which makes the text hard to
read on screen. It's better when printing text (at least in 3.1) and for PDFs
but that might come from the higher resolution. OO 3.1 still can't compete with
TeX when it comes to produce beautiful text :(

On Windows, the text looks much more smooth on the screen.

I highlighted the problematic areas in the images. All images were created on
openSUSE 11.1 with 100% zoom and 12pt font size.

= Times New Roman =
"pick" looks like there is a space between "pi" and "ck". "big" looks OK,
though. The "e" of "the" dangles in the air, too.

= Arial =
The space around "i" is either one, two or three pixels. Sometimes, the space to
the left and to the right of the letter is different.

= Utopia =
"receive" looks normal while "distress" has no space between the letters.

Sorry for the late reply.

Here is a document and a screenshot.

I'm seeing that the kerning gets better when I zoom to 140%. The screenshot has been made at 100%.

"his" looks correct, in "distress" the "i" is too close to the "d".

I'm no font expert, but subtle differences are visible upon scrutiny.

I know. But since LO is based on OO, I'd like to know if you're affected. If you are, then I can open another bug against LO to have the fix ported.

Your version looks better than mine (and both look better than what I saw in 2009).

How does OO render fonts? Do you use your own rendering engine or do you rely on the OS's TrueType renderer?

Same file in LibreOffice

Just for reference, the same file in LibreOffice

As you can see, the kerning is a bit more even but the fonts looks more ugly/darker in general.

Note: I switched the font in the third line to Liberation Sans 12.

If you switch all font to size 10, the kerning looks more uneven for me. For example, the "his" in the second line then looks almost like "h is".
