Finds favorites icons for web pages on the world wide internets by checking the HTML head or the standard favicon location. Then, do with them what you will.

Called "iconoclasm" because there was already a gem on gemcutter called "iconoclast". Boo! Hiss!


To get the favicon for a page, do:

favicon = Iconoclasm.extract('')

This will go and do a bunch of GETs (two or three, actually) on the url given. If you've already got the content and want to skip one of the GETs, you can pass the content in as the second argument.

content = get_some_content('')
favicon = Iconoclasm.extract('', content)

Iconoclasm.extract returns an Iconoclasm::Favicon instance, from which you can get the URL, content type, size, or access the binary image data. By calling valid?, you can check if the favicon is valid based on whatever my standards were when I wrote this (basically, whether or not it's actually an image).

You can save the image to a tempfile using, or more usefully, to a file at'path/to/file'). Fun times had by all.
