KernSmith.Fonts.Web

A web font source for KernSmith. Fetches WOFF fonts from CSS-based font CDNs by parsing @font-face responses.

Overview

WebFontSource implements the core KernSmith.Font.IFontSource abstraction. It fetches a stylesheet from a font CDN (Bunny Fonts, Google Fonts, or any compatible custom endpoint), parses the @font-face rules, and downloads the .woff file for the requested Unicode subset.

This is primarily useful in browser/WASM scenarios (e.g. running KernSmith in Blazor WebAssembly) where there is no filesystem and fonts must be obtained over the network.

Platform: Cross-platform (net8.0, net10.0). Uses HttpClient from the BCL.

Usage

dotnet add package KernSmith.Fonts.Web

using KernSmith;
using KernSmith.Font;
using KernSmith.Fonts.Web;

var source = new WebFontSource(WebFontProvider.BunnyFonts);
byte[] bytes = await source.GetFontAsync("Roboto", weight: 400);

BmFont.RegisterFont("Roboto", bytes);
var result = BmFont.GenerateFromSystem("Roboto", size: 32);

Providers

new WebFontSource(WebFontProvider.BunnyFonts);                 // privacy-friendly default
new WebFontSource(WebFontProvider.GoogleFonts);                // fonts.googleapis.com
new WebFontSource(WebFontProvider.Custom("https://my.cdn/css")); // any compatible endpoint

Subsets and styles

await source.GetFontAsync("Roboto", weight: 700, style: FontStyle.Italic, subset: "latin");
await source.GetFontAsync("Roboto", subset: "cyrillic");

Caching

Fetched fonts are cached in memory (keyed by family + weight + style + subset). Pass a diskCachePath to also persist across runs (leave it null on WASM):

new WebFontSource(WebFontProvider.BunnyFonts, diskCachePath: "cache/fonts");

Limitations

  • WOFF only — .woff2 URLs are ignored because WOFF2 uses Brotli compression, which KernSmith does not yet decode.
  • No family listing — CSS CDNs do not expose a discovery endpoint, so ListFamiliesAsync returns an empty list.

Build

dotnet build src/KernSmith.Fonts.Web/KernSmith.Fonts.Web.csproj
