Hi,
After reading the bug description, I think that you mean LO 4.0.6 (*below*) and 4.1.2.3 (*above*), right?
Comment 2 seppel 2013-10-30 16:23:00 UTC
yes, that's correct.
sorry for causing confusion.

please attach the original .odt file as well so we can test

Confirmed by Bug 71636.

Where is that font? Is it possible to attach it to this bug? I don’t have it on my 10.9 OS X system.
Comment 7 Florian Maier 2013-12-09 08:45:54 UTC
It is a proprietary font:

One possible download location:

Hi Seppel, I see: http://cl.ly/image/3R2u3f2D043F in Macintosh HD > Library > Fonts

Do you have all those entries as well? If you have bold, you should then be able to set your font to bold.

Please open your OSX font manager (ger "schriftenverwaltung") and check if you see any entry for bold.

Why is this bug on NEW? So far it has not been confirmed, so unconfirmed is the correct status. Setting to NEEDINFO since we need feedback from bug reporter.
Comment 9 seppel 2014-01-20 07:21:22 UTC
Hi
actually the font we use is "futura LT light", not "Futura Std". That might be a difference, I don't know exactly. And no - there's no "Futua LT Light Bold" on the system - well, maybe the "light" in the name and "bold" wouldn't fit too well to each other....
But the font can be shown in *bold*, but I think it is a kind of "calculated" by LO.. and in version 4.1.2.3 it is showing the distance between two letters wrong.
Comment 10 Florian Maier 2014-01-20 07:47:20 UTC
We use "FuturaStd-Light" shown as "FuturaStd-Light.otf" in the Fontmanager. Same Problem (#71636);

Comment 12 Adolfo Jayme Barrientos 2014-03-20 05:06:39 UTC
This should not be in NEEDINFO, or do triagers need to pirate every font just to confirm smething?

have you tried if the issues persist in more recent releases like 4.1.5 or 4.2.2?
Comment 14 tommy27 2014-03-20 05:54:03 UTC
sorry, I've just noticed that the duplicate Bug 76352 was already tested against 4.1.5 and 4.2.2 and confirms that the issue was not present in 4.0.6

I add "regression" to keywords
Comment 15 Milan Bouchet-Valat 2014-03-21 18:13:34 UTC
Indeed, in the duplicate I reported that I  observe the same problem with a standard Apple font, Geneva, and with a free font, Gentium[1], and. So no need to download a proprietary font.

Copying a remark from the other report:

I've found an old discussion about a similar problem with Geneva bold, and it was related to the fact that Carbon automatically created a pesudo-bold font, while Cocoa no longer does this:
http://typophile.com/node/59767

Most probably the new way LO uses to emulate a bold font where only a regular version exists is not as good as the old one.

QA housekeeping, setting back to NEW -- apparently valid, but never taken by a Dev.

If anyone wants to work on this, the relevant part of the code is here: http://cgit.freedesktop.org/libreoffice/core/tree/vcl/quartz/ctfonts.cxx#n78, one just needs to fiddle with the nStroke value until the result is acceptable.
Comment 27 ⁨خالد حسني⁩ 2015-04-26 11:18:31 UTC
For reference, the corresponding AOO code is here http://cgit.freedesktop.org/libreoffice/core/tree/vcl/aqua/source/gdi/ctfonts.cxx?h=aoo/trunk#n146, if AOO is giving a better result, then may be all is needed is to copy that part of the code.
