Color of Image is used to extract a color palette from a given image. Aside from being a native PHP implementation, Color of Image differes from many palette extracters as it works off a white list color palette. Below is the default palette:
The main advanage of working from a color palette is closer matching, as each pixel simply has to calculate the color-distance within the palatte and chose the best match. This is useful for working with color taxonomies as the taxonomy should have a finate amount of colors.
See an example of this in action here: http://www.rufflr.com/search/?color=ffcc33
Usage
// initiate with image
$image = new ColorsOfImage( 'https://www.google.co.uk/images/srpr/logo3w.png' );
// get the prominent colors
$colors = $image->getProminentColors(); // array( '#FFFDD', ... )And there we go!
Options
Precision
By default, ColorsOfImage will process every 10th pixel. This is for performance reasons, you can change this like below. The precision is a performance-to-time desicion.
$image = new ColorsOfImage( $src, 5 /* precision */ );Color Count
To control the amount colors returned set the third parameter.
$image = new ColorsOfImage( $src, 5, 3 /* number of colors to return */ );see https://github.com/humanmade/Colors-Of-Image/blob/master/CONTRIBUTING.md
