Dear Werner,
Now I'm trying to extend CJK bluezone patch to support
CID-keyed font using Adobe-{CNS1,GB1,Japan1,Korea1} CID.
It would be useful to apply autohint to non-TrueType
CID-keyed font embedded in PDF.
# I think it is useful to make the image comparing large
# character set.
It seems that FT_IS_CID_KEYED() macro does not detect
the CID-keyed font driven by t1cid driver (Type9 CID-keyed
font), because the driver setting FT_FACE_FLAG_CID_KEYED
is only cff driver.
It is possible to detect t1cid font by such conditional,
if ( 0 == face-num_charmaps
!FT_Get_CID_Is_Internally_CID_Keyed( face, is_cid )
is_cid )
so I have no strong request to modify FT_IS_CID_KEYED()
to detect t1cid, but it's slightly difficult to understand
that it is designed feature from the documents in freetype.h.
If you can remember why current FT_IS_CID_KEYED() ignores
t1cid, please let me know.
Regards,
mpsuzuki
