What is this?

Glyph Extractor is a small Python script for extracting font glyphs as PNG files. It supports TTF and OTF fonts and capable of extracting all glyphs out of them, including colored emojis.

Usage

• Clone this repo
• Install requirements with pip install -r requirements.pip
• Run the script python extract_glyphs.py <path_to_font>
• Find extracted glyphs in the output folder

Please note: if you want to extract glyphs with embedded colors (e.g. emojis) from OTF font you may also need to install Cairo binaries. You can do this with brew install cairo on MacOS. Please see CairoSVG documentation for other platforms.

Features

• Extracts all possible glyphs from the font file including emoji variations (skin tones and others).
• Supports filling glyphs with specified color (use --fill-color argument).
• Supports filling glyphs which have embedded colors (e.g. emojis). To do this use --no-embed-colors argument, but note that less count of glyphs may be exported.
• Automatically determines possible font sizes (no invalid pixel size errors).
• Exported glyphs are named as character hex value with additional information for emoji variations.
