WOFF 2.0

[jonassmedegaard]

Please support WOFF 2.0.

...or document more prominently if in fact it is already supported.

(see ananthakumaran/webify#8 for context)

That's out of scope of this project, sorry. If someone wish to do it - no problems, but i will not keep it in pending task.

The compression algorithm has been ported to JavaScript: https://github.com/devongovett/brotli.js

However, I don't yet understand whether it's just about compressing the generated woff or whether the whole ttf2woff mechanism would have to be adapted completely. @devongovett, do you have any insights into this?

[devongovett]

In addition to compression, WOFF2 also does additional transforms to the glyf and loca tables prior to compression, and has a different directory structure. Check out the spec for more details.

I see, thanks a lot.

[puzrin]

Anyway, i think it's better to make separate project for 2.0. For fontello i need small size, and have no special interest to spend time for one more convertor.

[backflip]

Would you want this to be done outside of fontello? Judging from the fact that the new format is already implemented in Chrome and Opera (http://caniuse.com/#feat=woff2) and will probably ship in Firefox in the near future (https://bugzilla.mozilla.org/show_bug.cgi?id=1064737), I'd expect this to become the new standard at some point.

Outside of this (woff 1.0) repo, and without me :) . See my profile, i have to do a lot of another projects, and will not be able to participate. If anyone really think, that it's better to keep project in fontello org, i'll create a repo and give all permissions.

[backflip]

Fair enough. And thanks for the awesome work you do!

I think I will give Emscripten a try. If this was used to port Brotli to JavaScript, I guess it should be possible to port https://code.google.com/p/font-compression-reference/source/browse/woff2/, too. I will keep you posted.

[puzrin]

Emscripten generates too big code. I compared, when decided to do zlib port for browser. Manual port is much more impressive.

[backflip]

Thanks to @nfroidure there is an Emscripten port: https://github.com/nfroidure/ttf2woff2

[puzrin]

4 mb size.

[backflip]

Well, the user's browser downloading a woff2 font instead of a woff one won't care about the size of the dependency used to generate it. :)

[puzrin]

As i said before - it's not interesting for me to use such solutions. This project's criterias are different from business ones.

[backflip]

That's certainly correct. I wasn't suggesting to add this to ttf2woff but rather documenting it for anyone interested in using it directly.

[puzrin]

Ok. I thought such cross-compiled projects are easy to search. But it you think those link will help to someone - no problem.

Also i'm ready to donate 1k$ for hight quality brotli port to JS (~ the same as we did in pako).

[nfroidure]

What you mean per high quality? If you mean a native wrapper, you should look twice, the emscripten is just a fallback for the native wrapper. Give your $1000 to Mozilla ;).

[puzrin]

I mean native implementation in JS, not cross-compiled. ~ the same as we did in pako for zlib.

[nfroidure]

In that case, i hope someone will do it, not my priority since we've got something working. Any PR doing the job will be merged though.
