Description robalexander 2003-11-13 13:30:18 UTC
I have attached a couple of documents. One is an OOo presentation, the other is
a PDF generated from Powerpoint under windows. Both contain the same line in
Arial, and the spacing between the characters is much more consistent in the
powerpoint version.

Worst examples:

'rs' in 'managers', r is too close to the s
'Man' in 'managers'. a is closer to the m than it is to the n
'Mul' in 'Multiple', too much space around the 'u'

FreeSans (bottom line of the OOo file) seems fine.

I can't reproduce the bug.
I think the nug depends on fonts which are not available on linux.
Please tell me if you have the used fonts on linux and windows.
Comment 5 Rainer Bielefeld 2004-02-06 19:05:25 UTC
I checked with 1.1.0 German version WIN XP: 645m19(Build8693), result WFM

Reporter, can you pls. add some more information:
Do you see that problem in all OOo components or only in Impress?
Really only with ARIAL or also with other fonts?
Can you add a screenshot?

Comment 6 robalexander 2004-02-09 09:58:11 UTC
It's been three months now, so I don't really remember why I thought this was a
problem. Looking at it again it's not that bad, although it's not perfect.
Looking closely at the PDF made from PowerPoint, that's not perfect either.

At one point I had a _very_ bad example (which my boss was quick to seize on as
a reason not to use OOo) but I haven't been able to duplicate it.

I have only seen this with Arial, and it seems to be better in Writer. Setting
'use printer metrics' seems to be better also. I have attached screenshots
showing what I get in Impress and Writer (both without 'use printer metrics').

I see your problem in _oo_font_bug_screen_writer.png', in the third line it
looks more like "Multi ple" than like "Multiple", so NEW. "gsl" because effect
is visible in various OOo components. I can't reproduce the problem with WIN,
seems to be LINUX only. Do you see the problem also if you use non bold ARIAL?

Can you please check whether hints are helpful and rlevant for you in issue
18276, issue 12820, issue 7287,

cp: please provide the information requested by cgu on Jan 8th.
cp->fme: please have a look, I think character spacing in writer is your black art
Comment 11 frank.meies 2004-02-09 12:38:40 UTC
FME->CP/HDU: Character spacing in writer may be my black art, but character
spacing in the edit engine is definitely not. If we use the virtual device for
text formatting, the characters on the screen are positioned depending on 

1) the positions (text array) the virtual device gave us and
2) the positions (text array) the output device (screen) gave us.

If these text arrays differ very much, the output may look somewhat distorted,
but since the problem is 

1) platform depending and
2) even worse in the edit engine,

I doubt that this is a Writer problem.
Comment 12 robalexander 2004-02-09 13:08:28 UTC
I have Arial font under Linux I think, it appears in the OOo font menus.

Non-bold example attached.

Comment 14 hdu@apache.org 2004-02-09 14:03:53 UTC
HDU->RobAlexander: Can you confirm that it looks better when you enable the
checkbox in "Tools -> Options -> Presentation -> General -> Use Printer Metrics..."?

Comment 16 robalexander 2004-02-09 14:24:39 UTC
I've added a screen shot with Use Printer Metrics set. It's certainly
_different_, whether this is better I'll leave to you to judge....I seem to have
lost my eye for this.
Comment 17 hdu@apache.org 2004-02-09 14:55:33 UTC
I'd say it looks better => the better the reference device the better the
formatting. When displaying some text with a zoom level other than 100% when the
text has been formatted with a 100% means one pixel per formatting unit, some
rounding problems are expected.

HDU->CL: Please use a high resolution reference device also for printer
independent formatting. I think you already have an issue for this?
Comment 18 clippka 2004-03-01 15:40:14 UTC
Andrè, please find out which resolution should be use. preferable the same as in
writer
Comment 19 groucho266 2004-03-01 16:46:34 UTC
Accepted.
