Zoe
Zoë is an open source tool for generating spritesheet images
Zoë is an open-source tool in the CreateJS suite that enables illustrators to generate spritesheet images and animation frame data from SWF files, facilitating seamless workflow between Flash authoring and HTML5/EaselJS animation. Zoë is designed to work with any AS3 SWF file version 9 or greater. It's best practice to have all your animations on the root timeline, and use labels to identify your different animations or frames. To begin, simply drag a swf file into Zoë, and click Export to create a SpriteSheet. Zoë and Easel support custom registration points on images. To define one, simply place an empty clip on your timeline labeled registrationPoint. If needed, you can also define multiple points per file.
