Bug 523454

Confirmed this bug in OpenOffice.org. Please find the attached screenshots.

OpenOffice document using Meera, rachana and suruma fonts with size 12

Created attachment 361193 [details]
Desktop with Meera font as default (size 12)

It will be nice if you update this bug with version of following packages
fontconfig
smc-meera-fonts and metacity

Versions:
fontconfig-2.7.1-1.fc11.i586
metacity-2.26.0-1.fc11.i586
smc-meera-fonts-04.1-6.fc11.noarch

IMHO reason behind this is font metrics of Meera

Rachana: Ascent: 1638, Descent: 410
Meera:  Ascent: 1147, Descent: 901
Lohit:  Ascent: 650, Descent: 374

looking at this Meera requires bit more vertical length of title bar for proper rendering as compared to Lohit. With compared to Rachana it requires bit more space below the character.

this Descent values is proper for Meera as there are some ligature required this much below space

see http://pravins.fedorapeople.org/Meera/meera_with_characters_below_base_extending.png

about Panel menus getting overlap is because SPACE character 0x0020, 

Meera : width = 563
Lohit : width = 350
Rachana : width = 466

see http://pravins.fedorapeople.org/Meera/lohit_space.png
http://pravins.fedorapeople.org/Meera/meera_space.png

so obviously Meera required more horizontal space as well, and panel menus getting overlapped, it will be nice if we can reduce its space value little bit

There is problem with OpenOffice, it is somehow not using .conf file, i am looking into it

Has the ascent-descent values for meera been changed recently? If so, please revert back to last working values if the change was not deliberate.

about underline presence in the windows title bar..
this is happening with glossy, clearlooks, fedora default theme and curvy looks

while digging more on this problem i found that when we remove 90-smc-fonts.conf
this problem is not coming, even i tried some other combination of scaling matrix of .conf file but still this problem is happening

so changing component to fontconfig

Has nothing to do with fontconfig.  I have no idea what the problem is, but it's definitely within 90-smc-fonts.conf as you said.

thanks behdad for quick comment, yep it looks like that

while chatting with  Matthias Clasen on same issue, we found

as problem is not coming with Crux theme but coming with other themes, he shown difference in crux and clearlooks theme

<mclasen> one thing I notice that might be relevant (not sure)
<mclasen> is that crux seems to have a version-2 metacity theme xml file (metacity-theme-2.xml
<mclasen> clearlooks only has version-1 file

just do move /usr/share/themes/Crux/metacity-1 folder to somewhere temporarily

problem will start occurring with Crux theme as well

so looks like we identified where problem is occurring, moving componant to metacity, might be then need to move to gnome-themese for quick fix

thanks Matthias

but now need to see what will be quick fix for this

What I meant was to go into the folder /usr/share/themes/Crux/metacity-1 
and move the file metacity-theme-2.xml to somewhere else, e.g. unused.xml
and see if the problem reproduces with the metacity-theme-1.xml thats in the same folder.

just moving metacity-theme-2.xml doesn't make any difference

upstream bug id

https://bugzilla.gnome.org/show_bug.cgi?id=597884

The issue disappeared when the matrix multiplication directive for Meera font has changed.From the entry for edit matrix directive for the font, the 'times' element and its child 'name' with value 'matrix' are removed. I don't know whether this is the right method because haven't seen any documentation regarding this. I think fontconfig is not well-documented about this entry.

The directive before change => http://pastie.org/651165

The directive after change => http://pastie.org/651160

BTW, strangely, the changes effected thru' fontconfig is not available in OpenOffice or KDE.

suresh

thanks suresh for pointer 

http://pravins.fedorapeople.org/smc-meera-fonts-04.2-2.fc11.noarch.rpm

please see if things are better with this rpm, if yes i will build smc-meera package again

rpm should resolve border bug of gnome-theme as well must not affect meera scaling rule in gedit

I can confirm that the fix mentioned by Suresh works fine in gnome applications. I did not use the RPM, but just edited the configuration file.
But the changes did not work on KDE and openoffice.

I am changing the component to Fontconfig again

santhoh can you test rpm as well?, so i can push this package for f12

behdad,
fontconf scaling rules for meera not working in KDE and openoffice, is there anything more need to do other than adding .conf file?

Created attachment 364504 [details]
Gedit with Meera size 10

Created attachment 364505 [details]
Gedit with Rachana size 10

I have tested the RPM, and can confirm that the fontconfig rule doesn't work with OpenOffice. GNOME apps seems to work ok. But it looks like to me that Meera/Rachana size difference is still present. See the previous two screenshots, each with size 10. Window border theme is Glossy.

OO.o is notoriously challenged by non-trivial text rendering; it's probably worth it to open a separate bug on OO.o so the RedHat OO.o maintainers can look at it

(QT is also often challenged, though less so, and I don't think anyone @rh is going to work on it)

built smc-fonts-04.2-2.fc12
requested releng for adding same in F12 Final, hope so will get that

as suggested by Nicholas, Better to open new bug for OO.o and QT

Tested latest rawhide (smc-fonts-04.2-2.fc12) and here are the results with Meera 10, Meera 12, comparing with Rachana 10 and Rachana 12 on Fedora default desktop:

Meera 10 -> underline appears on the gui and gedit title bar 
Meera 12 -> underline appears on the gui and gedit title bar and the close buttons become too larger in size. 
(above issues applicable to OO, FF and Qt as mentioned earlier)

Rachana 10 -> works well with no underline
Rachana 12 -> works well with no underline and buttons are normal in size.

Relevant screenshots attached for Meera 10, Meera 12, Rachana 10, Rachana 12.

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

fontconfig rules dont work well if we remove
            <name>matrix</name>
above line from smc-fonts conf file
but yes underline issue go out.


so issue is still present

Underline issue resolved - screenshot

Tested the updated gnome-themes-2.28.1-3.fc12 on F12. The underline issue has disappeared and all windows (oowriter, gnome-terminal, kwrite, gedit, firefox and evince) appears good to me. 

Screenshot for oowriter, gnome-terminal, kwrite, gedit, firefox attached for confirmation. Thanks Pravin.

i think we can close this bug now
I have already given reason's regarding extra title bar space, see comment #6 
if any issue regarding this please reopen bug
