I've taken a look at the changes. Some background first.
For cjk font, we do not create font metrics information from the
font. So there is never a afm file. The descent, ascent and width of
the whole font are specified in the fonts.dir(fonts.dir for cjk is
a bit different from latin fonts.dir). So getMetricsData
always failed on cjk fonts.
Since 7/17, the font's informations are treated differently b/w low and
high resolution. Under higher resolution, the metrics are looked up from
the metrics file, even for cjk font. Now we have the error as reported.
See GR_UnixGraphics::getFontAscent(GR_Font * fnt) and
GR_UnixGraphics::getFontDescent(GR_Font * fnt) in gr_UnixGraphics.cpp.
Since getMetricsData() always fail for CJK font, we have to use
We can create font metrics for CJK font (mostly, ttf) too, instead of hard
coded them inside the fonts.dir. This can be done with little change in
ttftools. However, since CJK as a whole are hacks in abiword now and the hacks
work relatively stable, I don't feels like to make much change before
1.0. When we start to make use of pango and stuff, hopefully, most of
the special treatements for CJK can be eliminated, and we then will have a
more generic approach toward i18n.
Patch attached (if I got the scales right).
