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.
