Moving to FC5Target, as FC4 is 'done', barring release blockers that
pop up.

Comment 3 Liang Zhang 2005-11-23 08:35:22 UTC
I have compared some Indic strings with English and Chinese strings, it seems
that English and Chinese are rendered aligned to the middle, but Indic string
aligned to the top in pango. 
I am not sure if this is desired Indic behavior, but this is a what pango does.

Any indic native speaker could confirm this?


Comment 4 Ray Strode [halfline] 2006-01-11 20:50:31 UTC
Can you guys file this upstream and post the bug to this report? thanks.

Comment 5 Leon Ho 2006-01-17 07:41:11 UTC
Lawrence has submitted this: http://bugzilla.gnome.org/show_bug.cgi?id=327163

Comment 6 Christopher Aillon 2006-01-27 20:50:08 UTC
this is upstreamde now.

Comment 8 Matthias Clasen 2006-02-10 06:06:48 UTC
The problem we are seeing here is simply that the indic and latin fonts which
are used have wildly different ascent/descent. GTK+ does not do any kind of
baseline alignment in situations like this, so text will only line up if the
ascent/descent of all involved fonts are relatively similar

Comment 9 Matthias Clasen 2006-02-10 19:33:13 UTC
Not fixable in fc5 timeframe.

Comment 10 Red Hat Bugzilla 2007-02-05 18:58:40 UTC
REOPENED status has been deprecated. ASSIGNED with keyword of Reopened is preferred.

Comment 11 Bug Zapper 2008-04-03 15:45:24 UTC
Based on the date this bug was created, it appears to have been reported
against rawhide during the development of a Fedora release that is no
longer maintained. In order to refocus our efforts as a project we are
flagging all of the open bugs for releases which are no longer
maintained. If this bug remains in NEEDINFO thirty (30) days from now,
we will automatically close it.

If you can reproduce this bug in a maintained Fedora version (7, 8, or
rawhide), please change this bug to the respective version and change
the status to ASSIGNED. (If you're unable to change the bug's version
or status, add a comment to the bug and someone will change it for you.)

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

The process we're following is outlined here:
http://fedoraproject.org/wiki/BugZappers/F9CleanUp

We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.

Rahul, could you take a look if this is still a problem?
The upstream bug is still open at least.

Comment 13 Rahul Bhalerao 2008-05-01 09:42:03 UTC
This was a problem with the auto-hinting done by freetype. Now that problem has
been solved since freetype-2.3.5. So this bug does not exists any more.We may
safely close this one.

Thanks for letting us know.
