HarfBuzz—حرف‌باز

@ElonBaldMusk @EricLengyel Supports COLRv1 emoji fonts now.

@harfbuzz @EricLengyel webgpu seems much faster than webgl. Also, no support for a font like Noto Color Emoji?

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 harfbuzz.github.io/hb-gpu-demo Also in the release is harfbuzz-world.cc, another single-file way to compile all of HB. github.com/harfbuzz/harfb…

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: harfbuzz-world.cc

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

@harfbuzz What about the FFP

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

@harfbuzz @EricLengyel I checked last 30 commits and all contain co-author by claude. It's sad that such an important library uses too much ai coding. When those all features tested? Written by ai tested by ai

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

@harfbuzz @EricLengyel So... What do we still need freetype for? Or can we switch without compromises?

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

@harfbuzz @EricLengyel Now this is the news that people should like and repost, not some fit snake text adjustments 😁

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

@harfbuzz Does it support CJK? I added Chinese, but it didn't work.

Check out the emscripten'ed web demo. Interact with it with the mouse. Or press space to animation rotation. behdad.org/hb-gpu-demo/

@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 i thought so too but webgl2 report's showing green for me was going to run DDU anyway so ill lyk if it changes anything

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 behdad.org/hb-gpu-demo/

@tauinos Your browser probably doesn't support WebGL2 for some reason. Probably Firefox blacklisted your GPU/driver combo. What does webglreport.com/?v=2 think? I added a descriptive error message to the demo. Thanks.

@harfbuzz ff 149.0, windows 11 console is returning NS_ERROR_NOT_AVAILABLE

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

@harfbuzz just wondering if there's firefox support? (just seeing a gray screen rn)

@cupofc0t Should be fixed. Thanks for reporting.

@harfbuzz 🤓

@leduyquang753 Should be fixed. Thanks for reporting.

@harfbuzz The letter M has some trouble.

@cupofc0t Ouch. What GPU / operating system?

@leduyquang753 Thanks. Will check.
