Hi, With hb-view, I have tried a font which has chaining contextual substitution feature (gsub lookup type 6). It turned out that the rendering of harfbuzz-ng was not satisfactory.
Command for test: ./hb-view --font-size=48 ~/.fonts/HANDotum-LVT.ttf "가나갈날ᄀᆞᄂᆞᄀᆞᆯᄂᆞᆯ" > ganada.png Font tested: http://ftp.ktug.or.kr/KTUG/hcr-lvt/HANDotum-LVT.ttf (it's huge: 13M) Result of harfbuzz-ng (above) compared to ICU library (actually openoffice; below): http://people.ktug.or.kr/~nomos/mine/screenshot_harfbuzz_openoffice.png Yes, I know that harfbuzz-ng does not provide Hangul Jamo shaping (ljmo, vjmo, tjmo) yet. However, this font has "calt" feature which is equivalent to ljmo + vjmo + tjmo. It seems that harfbuzz has invoked this calt feature for rendering; and the result was good to a large extent. As shown in the picture, however, last two Korean syllables ("ᄀᆞᆯᄂᆞᆯ") are not rendered correctly. This makes me wonder whether it is a bug of harfbuzz-ng or not. -- Dohyun Kim College of Law, Dongguk University Seoul, Republic of Korea _______________________________________________ HarfBuzz mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/harfbuzz
