Hi Patrick,

Thanks for answering and tidying the example - I'm still very much learning what
is possible.

No, I don't think a feature request is necessary, because the workaround gives
me exactly what I need. I had actually found and tried it before, but without
success, thus thinking it did not work (or I did something wrong). The problem
was that I never put the value high enough to see any effect. This workaround
will help me with another problem as well. It's great for vertical space 
control.

Thanks,

Didi

Inconsistent line height with Cambodian Unicode 2

2010-07-08 Thread Didi Kanjahn 
 I'm not top-posting

All 3 columns in the Khmer example below have a different height.
The latest version tested was 2.13.23-1.
The font selected in the first example is a Microsoft font, but any Khmer
Unicode font I have tested shows the same behavior. The font 'Khmer UI' that
comes with Windows 7 as default font behaves very differently (non-standard)
from other fonts, it may not show the problem. I can provide fonts of my own.

Some fonts can be downloaded at:
http://sourceforge.net/projects/khmer/files/Fonts%20-%20KhmerOS/KhmerOS%20Fonts%205.0-%20LGPL%20Licence/KhmerOS_.ttf/download

Further below a second example using a Khmer Unicode font, but with Roman script
letters only. Here all columns have the same height.

Hi Didi,

As far as I know, it's not possible for the line height to be
calculated correctly, because each character or group of characters is
a separate piece of markup.

In the future, we might consider switching more markup functionality
to Pango so that arbitrary text markup is processed line-by-line and
paragraph-by-paragraph.  This would solve the line-height issue you
are seeing.

But I don't know if/when this would ever happen.  It would require a
large overhaul of the markup infrastructure.

Would you like this to be a feature request instead?
