Blended Colours by Opacity, a PHP Function

by: admin March 25, 2007 20:54:01

In plain English: if the foreground colour is FFFFFF (white) and the background color is 000000 (black), and the opacity level is set at 50, I would expect the function to return 808080 (grey or gray).

How does AdSense, or any other Contextual Advertising Network, fill their ad units with unique advertisements? This is a question I have been regularly asking myself the last couple of days.

A couple of days ago, I woke up with this urge to create my own "contextual advertising" thingy for my network of sites.
