Description Lawrence Lim 2006-01-16 05:22:11 UTC 
Please describe the problem:
Indic glyphs are misalign to some roman glyphs after indic have been
resized. Please see the attachment for the sample. It seems related to
either freetype, pango, or the font.

Steps to reproduce:
1. LANG=hi_IN.UTF-8 evolution
2.  new mail
3. 


Actual results:
different translations is misaligned to each other



Expected results:
should be aligned

Does this happen every time?
YES

Comment 1 Matthias Clasen 2006-02-10 06:27:31 UTC 
The problem seen here is missing baseline alignment. The indic and latin fonts have wildly different ascent/descent, thus their baselines don't line up very well without explicit baseline alignment, which GTK+ does not currently do.
Comment 2 Owen Taylor 2006-02-10 14:54:17 UTC 
To do this well, you may need not just straightforward baseline alignment,
but baseline adjustments for different scripts 
(see http://www.microsoft.com/typography/otspec/base.htm)
Comment 3 Matthias Clasen 2006-02-10 15:02:44 UTC 
Owen, do you think it would be reasonable to do this with an "extended geometry management" interface, where containers can ask their children about a baseline they want to be aligned on ? It would probably only be relevant for labels or
widgets whose "main" child is a label, like buttons.
Comment 4 Matthias Clasen 2013-02-04 03:06:07 UTC 
moving this to pango
