jeff

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: usable in command line or through the API it can be used to do batch extraction on multiple SWFs.

Made in Wizcorp.

Install

For use as a command line:

`npm install jeff -g`

For use as an api:

`npm install jeff`

Use

Command line: jeff -s mySwf.swf

API:

	var jeff = require('jeff');

	var options = {
		source: 'mySwf.swf'
	};

	jeff(options);

Here is a complete list of Jeff's options.

Operation

• Will parse the input directory to find SWF files corresponding to the given source file pattern.
• Will sequentially parse and process the SWF files.
• Will export JSON meta-data and images corresponding to the SWF files.

Roadmap for unsupported features

• Texts (Static/Dynamic)
• Buttons
• Embedded fonts
• Sounds
• ActionScript

Roadmap for extract options

• Option to extract shapes under vectorial format
• Option to extract meta-data under keyframe based format (as opposed to per frame transformation matrix)
