What is the best way to get the color histogram of a html page as rendered, when I have the html and css files locally? I can think of a screen capture and then analyzing it using some graphic tool, but is there a more direct way to do this, for example, something like calculating it from the html and css information using JavaScript?

    You could use html2canvas.hertzen.com to render the page body into a canvas and then access the rendered pixel via the canvas image data. net.tutsplus.com/tutorials/javascript-ajax/… Commented Jul 30, 2013 at 5:31

I am not sure about javascript, but you can use python with Qt and webkit as described in this post

There is also a python package inspired by the post

Hope that helps
