Emoji Extractor
Overview
This skill provides a workflow and tools to extract emoji glyphs from font files and save them as standalone SVG files. It uses a Node.js script to parse the font and generate the SVG path.
When to Use
- You need an SVG version of a specific emoji.
- You have a font file (or URL to one) and want to extract one or more glyphs from it.
- Note: Works best with standard outline fonts (e.g. NotoEmoji-Regular). Color bitmap fonts (like NotoColorEmoji) might not be fully supported or may fail to yield vector paths.
- You want consistent emoji assets across different platforms by embedding them as SVGs.
Usage
Prerequisites
- Node.js installed.
- Dependencies installed in the
scripts directory (run npm install in .agent/skills/emoji-extractor/scripts).
Extraction Command
Use the extract_emoji.js script to extract emojis.
node .agent/skills/emoji-extractor/scripts/extract_emoji.js --font <path_to_font> --emoji <emoji_list> --out <output_file_or_dir> [--force]
Arguments:
--font: Path to local font OR URL. URL fonts are cached in tmp/fonts_cache/ to avoid repeated downloads.--emoji: Comma-separated list of emojis (e.g. "🔥, 🚀") or unicode hex codes.--out: Output directory (recommended for batch) or file path.--force: Overwrite existing files (default: skip if exists).
Examples
Extract 'Fire' emoji from local Noto font:
node .agent/skills/emoji-extractor/scripts/extract_emoji.js --font "assets/fonts/NotoColorEmoji.ttf" --emoji "🔥" --out "assets/emoji/fire.svg"
Extract 'Rocket' emoji from URL:
node .agent/skills/emoji-extractor/scripts/extract_emoji.js --font "https://example.com/fonts/NotoEmoji-Regular.ttf" --emoji "🚀" --out "assets/emoji/"
