Black and white fallback as standalone font about twemoji-color-font HOT 5 CLOSED

The fork referenced in twitter/twemoji#299 is just committed versions of my generated traces. IMO the traces are acceptable, but not that good compared to what an artist would create. Many of the images cannot be directly converted to one color. I spent a long time adjusting/massaging the settings on the generation process to create something reasonable looking to have anything/something to fall back to. It's just a total hack though 😆

You should try out the generation process: https://github.com/eosrei/twemoji-color-font#building Maybe you can adjust it to make them better?

Thanks for your response! Now that I see what you're doing (and have taken a closer look at the fallback traces), it doesn't make a ton of sense to be using them as a standalone font. It's great that you created this fallback option though!

There's one key reason an artist could improve on these line traces - the geometry of the emoji is lost to a degree. Compare the line-traced emoji with the originals at 24px, for example.

I can try post images of a "better" alternative I tried, if that'd be helpful. But I tried to generate monochrome icons by:

1. Desaturating a more complex SVG - I picked U+1F6A4 as a personal favourite ;)
   At this stage, a perfect, grayscale emoji is made (but with multiple fill colors).
2. Converting desaturated fill colors to black (with fill-opacity used to convey lighter color)
   Now we have either 1️⃣ a great black & white emoji or 2️⃣ a horrid mess of overlapping paths.

Unfortunately, this is highly destructive for icons with overlapping paths. But if an artist was willing to do this, only complex icons would need manual tweaking so that paths don't overlap.

Hold on, what if you just:

• desaturate the images
• convert them to raster
• then trace them back to vector (in such a manner that paths do not overlap)
• convert desaturated fill colors to shades of black (fill-opacity!)

Anyone willing to give this a go? 😃

I'm all for making these better. I spent a significant amount of time inventing the current process. As far as I can tell actual humans, not 🤖 will have to parse each to make them graphically correct. Want to be proven wrong though!
