title: Iphone Core Image Filter
body: <p>I'm wondering about that, I have seen into many sites describing that Core Image filters on Iphone doesn't support by Apple. But I have seen Core image filter in Core Animation example page on the Apple developer site. 
  just look at here <a href="https://web.archive.org/web/20100831121232/http://developer.apple.com/iPhone/library/documentation/Cocoa/Conceptual/CoreAnimation_guide/Articles/AnimatingLayers.html#//apple_ref/doc/uid/TP40006085-SW1" rel="nofollow noreferrer">Iphone OS Reference Library</a>, you will see that example on this page</p>
  
  <pre><code>CIFilter *filter = [CIFilter filterWithName:@"CIBloom"];
  [filter setDefaults];
  [filter setValue:[NSNumber numberWithFloat:5.0] forKey:@"inputRadius"];
  </code></pre>
  
  <p>Any description for that would be appreciated.</p>
