Most anyone who’s used iTunes’ album view will know about their color picking mechanism.\u00a0 I was curious about how this might be done and found this question on Stack Overflow: How does the algorithm to color the song list in iTunes 11 work?<\/a><\/p>\n

So I set about creating an equivalent in PHP.\u00a0 I settled on using the IMagick PHP extension for grabbing pixel data and doing blurs.<\/p>\n

The Results<\/h3>\n

\"mizu\" Mizu<\/strong> (Water)<\/p>\n

\"moon\" Tsuki<\/strong> (Moon)<\/p>\n

\"fall\" Aki<\/strong> (Fall)<\/p>\n

\"Chibi\" Chibi<\/strong> ^_^<\/p>\n

The How<\/h3>\n

It’s largely based on the accepted answer given on the Stack Overflow question mentioned earlier. Except I separate potential highlights from the selected background based on a luminance ratio which produces more readable text, and there’s some additional logic for trying to pick contrasting highlight colors.<\/p>\n

The Source<\/h3>\n

Source is available on BitBucket: https:\/\/bitbucket.org\/epb9000\/image-color-dominator\/<\/a> Not much in the way of documentation, so hopefully the comments on the class aren’t horrifically confusing. I’ll re-read them later and maybe make changes.<\/p>\n","protected":false},"excerpt":{"rendered":"
