emoji-extractor

This is a small ruby script that extracts the Apple Color Emoji PNG Symbols from their corresponding system font located at /System/Library/Fonts/Apple Color Emoji.ttf. The extracted assets will be placed in a subfolder for each resolution in a subfolder called "image" in the containing folder. File system structure as follows:

.
├── README.md
├── emoji_extractor.rb
└── images
    ├── 160x160
    ├── 20x20
    ├── 21x21
    ├── 32x32
    ├── 40x40
    ├── 48x48
    ├── 64x64
    └── 96x96

It was updated to work with current versions of ruby and include assets for the new emojis as introduced in OS X 10.10.3 / iOS 8.3 (defined in Unicode standard 7.0).
