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)
