Classpublic final class ZoomBlur
ImplementsIFilter

The ZoomBlur class is a filter that applies a blur on a zoom-out displacement.

On th one hand this filter is using simple geometry but on the other hand it is also a blur filter that has to interpolate the color values between all the pixels that have been hit which makes it slow.

Supported formats:


Example 
  
  var filter: ZoomBlur = new ZoomBlur();
  
  var video: WebCam = new WebCam( 160, 120 );
  var image: Image = new Image( 160, 120, ImageFormat.RGB );
  
  image.loadBitmapData( video.getCurrentFrame(), true );
  
  filter.apply( image );
