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 <a href="mailto:HarfBuzz@lists.freedesktop.org" target="_blank">HarfBuzz@lists.freedesktop.org</a> <a href="https://lists.freedesktop.org/mailman/listinfo/harfbuzz" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/harfbuzz</a> </blockquote></div> -- <div class="gmail_signature" data-smartmail="gmail_signature">behdad <a href="http://behdad.org/" target="_blank">http://behdad.org/</a></div> </div>
