Reading all Colors from an Image to convert it to CSS

Question

Im trying to make a Image to CSS convertor, which works in PHP.

I have tried looking at the javascript convertor at: http://codepen.io/blazeeboy/pen/bCaLE

I see that it make it into a canvas element and scans each pixels for the color, which would not make it possible the same way in PHP.

If you're looking to create Data URIs (see [examples](http://en.wikipedia.org/wiki/Data_URI_scheme#Examples)), then all you need to do in PHP is use `base64_encode` (see [discussion](http://php.net/manual/en/function.base64-encode.php#110868)). You won't need to read the pixel data, because you're just converting the image file to a ASCII format. — thirdender, Jan 03 '13 at 22:00

You can use PHP's GD2 functions, such as imagecreatefrompng and imagecolorat.
