Error message on page loading in Chrome Version 34.0.1847.60 beta :

Uncaught SecurityError: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': The canvas has been tainted by cross-origin data.

To make code more flexible for advanced webapps, ImageAnalyzer should get Image object, not path to avoid doubled image loading in case of previous canvas usage. Eventually switch(typeof image) to select proper behaviour. Also in case of offline usage init should be executed at the end, as with local Apache setup onload may fire before all function are defined.

Would you mind adding a license to this project?

Hi,

First of all, I'm very impressed by this JS implementation.

But, here's my issue: I felt confused by the fact that the app.coffee, and thus the app.js code contains a usage sample.
And, if I'm correct, the app is right now only able to change the color of 3 pre-determined HTML elements with predefined classes.

IMHO, this app should just behave like a "lib", kinda like a plugin that I could load and run on whatever picture I want, and that could return a result that I could process my own way. Ex: return a map with the primary, secondary and detail color codes.

Do you think it's possible?

Just do

git checkout -b gh-pages
git push origin gh-pages
