Description johanneseva 2008-01-19 17:35:20 UTC
Under Linux Mint 4.0 and Ubuntu Gutsy Gibbon 7.10, the default line spacing for
normal documents is far too big.

Bug reported and confirmed on Launchpad:
https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/126784

Apparently it doesn't concern Fedora.

I observed this bug on OOo 2.2, 2.3, and 2.4 snapshot 680_m2.
On Windows, No problem, the line spacing is ok.

The same document opened under Linux shows a far too big line spacing (about
140%), so the whole document looses its Layout. It is very problematic since OOo
becomes really unusable.
I have to use the bugfree windows version on a Virtual Machine since there is no
fix!

This bug shows up on all 4 machines in my Family, all PCs under Ubuntu or Mint.
The bug also existed on Ubuntu Feisty 7.04

This bug is also mentionned here:
http://www.linuxjournal.com/node/1000178

And there is a solution, too - namely install the "msttcorefonts" package.
Why does the line spacing grows when msttcorefonts is not installed?
I hated OOo for that bug many years, without finding any clue for how to solve
the problem - until today.
Comment 1 eric.savary 2008-01-21 11:39:52 UTC
@johanneseva: Please try also to choose another printer driver/queue. This may
have an influence on the document layout.

@hdu: have you an idea why this may NOT happen with "msttcorefonts"?
Comment 2 hdu@apache.org 2008-01-21 12:38:49 UTC
Without any bugdoc, screenshot or PDF export I have to speculate: If a document requires e.g. "Arial" and 
this font is not available on this system then a different font gets selected. If this surrogate font is not 
absolutely identical to the original font (which is the usual case) and has different line metrics, then the 
resulting layout will have different line metrics.

@johanneseva: Could you attach a very short document which has the problem and the the two resulting 
PDFs? One without corefonts installed and one with corefonts installed.
Comment 3 johanneseva 2008-01-27 21:12:34 UTC
Sorry to respond that late - next time it will be faster!
Anyway, here are 2 pdfs, one with msttcorefonts installed, one without. And the
corresponding .odt file, which remains the same in both case!
The difference in Layout is *huge* - and makes OOo seriously unusable if you
have many documents to import and don't know that you have to install
msttcorefonts to solve the problem.

I don't know if this is relevant:
In both case (msttcorefonts installed or not) OOo shows Times or Arial as font
name. However before installing the msttcorefonts package for the first time
(fresh Ubuntu or Mint install), the police shown by OOo was "arial" instead of
"Arial".
(maybe a hint showing that OOo does not find the real Arial font.)

If I can help next time, I'll try to answer faster - sorry for my English once
more...

Comment 7 hdu@apache.org 2008-01-31 11:54:30 UTC
The latest attached file shows that the non-available Arial got replaced by Nimbus SansL. Is there another 
font on that system that would have been a better substitute (with better similarity, especially better 
matching metrics)?
Comment 8 johanneseva 2008-01-31 16:45:27 UTC
You're absolutely right, the Arial and Times fonts were replaced through their
Nimbus equivalent, 
Nimbus Roman No9 L and
Nimbus Sans L
which have definitely very different metrics. Especially line spacing is far
bigger, but the metric is overall very different.

So I tried some fonts. 

PERFECT MATCH:
Liberation Sans 
(and Liberation Serif for "Times")
The metrics are really the same!
And Red Hat's Liberation Fonts are GPL!

APPROXIMATE MATCH:
MgOpen Moderna & FreeSans 
(both have the same metric, smaller line spacing than Arial does)

VERY APPROXIMATE MATCH:
BitStream Vera Sans or DejaVu Sans 
(both have the same metric, bigger line spacing than Arial does)

VERY POOR MATCH:
Nimbus sans L
(far bigger line spacing than Arial does)

As these are all font familys, it would be great to replace the matching for
Arial, Times and Mono/Courier.

I would of course recommand to replace all the matching by the Liberation font
family, as they are more than GPLed. (GPL + Font exception to make them even
"more" free!)

Are they stoppers for this idea?

I hope this great problem for OOo & Linux can be solved!

PS. See this small article on this topic:
http://www.press.redhat.com/2007/05/09/liberation-fonts/

PPS. I'm not a Red Hat fanatic or anything, I just tried these fonts today and
they seem to be a really great equivalent to MS fonts, AND a "free" solution to
this problem!

Some more links for this topic:

http://fischer.org.za/bl0g/2007/05/23/font-vs-font/

http://robitaille.wordpress.com/2007/05/12/liberation-fonts/

There are many more forums discussing this issue, and many of them speak about
line spacing problems...

A version of the Liberation Fonts with font hinting should be released oficially
soon. Unofficially:
https://bugzilla.redhat.com/show_bug.cgi?id=427791

Shall the issue status be changed to confirmed?
Comment 10 hdu@apache.org 2008-02-01 07:54:50 UTC
OOo 2.4 will have a much better integration of the Liberation fonts (#151427#), so I'm changing the 
status to WORKSFORME, please verify in OOo 2.4

Also see issue 85106 about interesting opinions regarding the free-ness of these fonts.

Comment 11 michael.ruess 2008-02-04 16:24:07 UTC
Closed, should work with OO 2.4. Try out with currently available OO 2.4 dev
build OOH68m6.

Comment 14 johanneseva 2008-02-12 19:59:03 UTC
I attached a pdf showing the result with ooo-dev OOH680_m6.
It's better, however, the result is still 2 pages big instead of one. 
Though liberation fonts are installed, there are not used.

Maybe because of changes in the embedded fonts, the pdf is bigger now:
287 KB instead of 107 KB with OOo 2.3 !!!

OOo 2.3 exports pdf which embedds 
Times-Roman
Times-Bold
NimbusSansL-Regu


ooo-dev OOH680_m6 exports pdf which embedds 
NimbusRomNo9L-Regu
NimbusRomNo9L-Medi
DejaVuSans

No trace of Liberation fonts.
As replacement of msttcorefonts, FreeSans would fit better than DejaVuSans as
replacement to Arial.

NimbusRom still seems to be the replacement for Times New Roman.
Could it be changed in favor of FreeSerif, or if it's not possible DejaVu Serif?

I would be pleased to test more changes - thank you very much for the already
improved version!
Comment 15 hdu@apache.org 2008-02-13 09:23:22 UTC
Ah, then probably the new fontconfig integration recommends the substitutions you noticed.
Type "fc-match Arial" to see what the system's libfontconfig suggests.

To test, if disabling libfontconfig assisted substitutions and using OOo's original application specific 
substitutions helps, please set the environment variable SAL_DISABLE_FC_SUBST before running soffice 
(see issue 85483 for details).

Comment 16 johanneseva 2008-02-13 23:07:38 UTC
fc-match Arial with ttcorefonts:
Arial-Regular.ttf: "Arial" "Normal"

fc-match Arial without ttcorefonts:
DejaVu-Sans.ttf: "DejaVu Sans" "Book"


Honestly, I don't really understand all the "environment variable
SAL_DISABLE_FC_SUBST" thing, even if I read issue 85483.
Seems to be above my level...

Anyway, the problem is not to resolve the bug for me - I don't care installing
msttcorefonts or using OOo's original application specific substitutions with
liberation fonts.

The problem is for users without msttcorefonts installed (Ubuntu users by
default for example) who will get their layout messed up without even knowing why!
Comment 17 hdu@apache.org 2008-02-15 15:14:52 UTC
The fc-match results indicate that fontconfig instructed OOo to replace "Arial" with "DejaVu Sans Book". 
If DejaVu is not the best match on this system then please report this problem to the distributor (e.g. 
Ubuntu, RedHat, etc). There are potentially many many more mismatches in fontconfig's knowledge of 
the relationships of different fonts.

Before OOo did the fontconfig based substitutions described above OOo used its own cross-platform 
expertise. Since the distributors insisted that OOo follows fontconfigs substitution recommendations 
they will probably be quite happy to fix all the mismatches themselves.

To check how OOo used to substitute fonts you can do the following steps:
- open a terminal
- change the directory to the OOo's program folder
- type "SAL_DISABLE_FC_SUBST=1 ./soffice.bin"
- check the document you reported
