alias in pangox.alias

[Takao Fujiwara - Tokyo S/W Center <Takao Fujiwara Sun COM>]

Hi experts,


I have quality issues about Japanese fonts in Pango. 
When we choose small size fonts in GNOME2.0.2 (pango 1.0.5) 
+ Solaris 9, The rendering in Japanese fonts are very ugly. 

I have one remedy to add some alias to pangox.alias. 
However I don't have an explicit answer that it is no problem 
for pango specification. I would like to ask you it.

Do you have any ideas to add gothic and mincho as aliases to 
pangox.alias below?

gothic normal normal normal normal \
  "-ricoh-hg gothic b-medium-r-normal--*-*-*-*-c-*-jisx0201.1976-0,\
   -ricoh-hg gothic b-medium-r-normal--*-*-*-*-c-*-jisx0208.1983-0,\
   -ricoh-gothic-medium-r-normal--*-*-*-*-*-*-jisx0212.1990-0,\
   -ricoh-gothic-medium-r-normal--*-*-*-*-*-*-jisx0213.2000-1,\
   -ricoh-gothic-medium-r-normal--*-*-*-*-*-*-jisx0213.2000-2,\
   -adobe-helvetica-medium-r-normal--*-*-*-*-*-*-iso8859-1"

mincho normal normal normal normal \
  "-ricoh-hg mincho l-medium-r-normal--*-*-*-*-c-*-jisx0201.1976-0,\
   -ricoh-hg mincho l-medium-r-normal--*-*-*-*-c-*-jisx0208.1983-0,\
   -ricoh-mincho-medium-r-normal--*-*-*-*-*-*-jisx0212.1990-0,\
   -ricoh-mincho-medium-r-normal--*-*-*-*-*-*-jisx0213.2000-1,\
   -ricoh-mincho-medium-r-normal--*-*-*-*-*-*-jisx0213.2000-2,\
   -adobe-utopia-medium-r-normal--*-*-*-*-*-*-iso8859-1"

This remedy can fix problems that characters are very ugly 
in small Japanese fonts when gtk applications(Mozilla, etc) 
choose any fonts beside sans, serif, and monospace.
I think that the issue occurs because 'gothic' in jisx0208 
does not have small point size but 'hg gothic b' in jisx0208 has 
small point size.

Sans, serif, and monospace have similar problems. If sans has 
only sun-gothic as jisx0208 font, pango renders ugly glyph. 
But If sans has ricoh-hg gothic b as jisx0208 font, pago renders 
fine glyph.

So when pango refers 'gothic', I would like to point 'hg gothic b' 
in jisx0208/0201 against 'gothic', and when pango refers 'mincho', 
I would like to point 'hg mincho l' in jisx0208/0201 against 'mincho'.
pangox.alias in Solaris has distinct directory(/etc/pango/$locale/pangox.alias) 
by locale, so pangox.alias can be set in each locale.

I think this remedy has a pretty pit, i.e. 
If set 'gothic bold normal normal normal' in pangox.alias, 
user can see duplicated  'Bold' fonts in gnome-font-properties.
It is no problem in 'gothic normal normal normal normal' because 
gothic fonts originally have 'medium' style but not 'normal' style.

I do not join this mail alias, so please mail to me directly.
Thanks in advance,
