HarfBuzz—حرف‌باز

The free and open text shaping library / font platform

[HarfBuzz—حرف‌باز @harfbuzz]

@ElonBaldMusk @EricLengyel Supports COLRv1 emoji fonts now.

HarfBuzz 14.0.0 is out with the new hb-gpu library for GPU text rasterization based on the Slug algorithm by @EricLengyel. Demo is up at https://t.co/afwRvvtyG3

Also in the release is https://t.co/3lDWLMHVm9, another single-file way to compile all of HB.

HarfBuzz 14.2.0 is released with support for COLRv1 color-font rendering in hb-gpu, as well as streamlined API in hb-raster & hb-vector. See them all in action at our new website: https://t.co/lXIC15gPQq

@Fancy2209Real Slug requires a fragment shader as that's where the rasterization happens. It won't work with the FFP.

@weffer4005037 @EricLengyel Yes. All code was reviewed by @behdadesfahbod.

@rokups @EricLengyel FreeType does hinting, which this doesn't.

[HarfBuzz—حرف‌باز @harfbuzz]

@AdriangGray @EricLengyel And I assure you, it's NOT an April fools joke!

[HarfBuzz—حرف‌باز @harfbuzz]

@yisibl It does. Press the "text" button or type "t" and enter some Chinese text for it to render.

Check out the emscripten'ed web demo. Interact with it with the mouse. Or press space to animation rotation. https://t.co/4LZMwWhUMs

hb-gpu is a new HarfBuzz library under development, that uses the Slug algorithm for encoding glyph shapes for rasterization on the GPU. We are looking for early testers and adopters, probably from the #gamedev community. Hit us with a comment:

@tauinos Thanks. Looks like *sometimes* the demo renders with black screen still; any interaction will make it work again. Is it that by any chance?

[HarfBuzz—حرف‌باز @harfbuzz]

Added stem-darkening at small font sizes to improve appearance. Without stem-darkening text at small size looked washed-out.

Now with Metal & WebGPU implementations in the library / demo as well. Both WebGL and WebGPU demos can be seen at https://t.co/4LZMwWhUMs

@tauinos Your browser probably doesn't support WebGL2 for some reason. Probably Firefox blacklisted your GPU/driver combo. What does https://t.co/UFIwiKInGM think?

I added a descriptive error message to the demo. Thanks.

@tauinos Which version / OS? Works for us on Linux & Mac. Does reloading help?

[HarfBuzz—حرف‌باز @harfbuzz]

@cupofc0t Should be fixed. Thanks for reporting.

[HarfBuzz—حرف‌باز @harfbuzz]

@leduyquang753 Should be fixed. Thanks for reporting.

[HarfBuzz—حرف‌باز @harfbuzz]

@cupofc0t Ouch. What GPU / operating system?

[HarfBuzz—حرف‌باز @harfbuzz]

@leduyquang753 Thanks. Will check.
