Jeff converts Flash™ SWFs into a JSON/PNG format for high performance usage in HTML/JavaScript. The extracted content could be used to integrate Flash™ Animations in your game using your favorite HTML Game Engine.
Contains a variety of options to allow you to get performance where you need it:
Optimised speed performance:
- Asset rasterisation (faster than vectorial drawing)
- Image Atlas creation (to enable batch sprite rendering in WebGL)
- Extracting images with power of 2 dimensions (to enable mipmapping)
Optimised memory performance:
- Image compression (lossy and loss-less compressions)
- Animation Scaling (to rasterise images at the exact size needed)
Optimised ease of use:
- Gathering several animations in a single output: Reduced number of assets to manage
- Frame by Frame rasterisation: for easy integration in your game
Very good scalability: from both the command line as well as through the API, it can be used to do batch extraction on multiple SWFs.
