I'd like to get a character width and height and am thinking to use hb_buffer_get_glyph_positions()->x_advance .
I tried hello-harfbuzz with noto-emoji fonts: https://github.com/behdad/harfbuzz-tutorial/blob/master/hello-harfbuzz.c https://github.com/googlei18n/noto-emoji/tree/master/fonts Seems hello-harfbuzz can get x_advance with NotoEmoji-Reqular.ttf but it failed in FT_Set_Char_Size() or FT_Set_Pixel_Sizes() with NotoColorEmoji.ttf. Even if I ignore the return value of FT_THROW(Invalid_Pixel_Size) from FT_Set_Pixel_Sizes(), seems hello-harfbuzz does not return the accurate x_advance. Do you have any ideas to resolve it? I'm using harfbuzz 1.3.2 and freetype 2.6.5 and testing U+1F469. % ./hello-harfbuzz \ /usr/share/fonts/google-noto-emoji/NotoColorEmoji.ttf \ "👩" Seems NotoEmoji-Reqular.ttf is a scalable font and NotoColorEmoji.ttf is a fixed size font. _______________________________________________ HarfBuzz mailing list HarfBuzz@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/harfbuzz
