Classpublic final class ConvolutionBlur
InheritanceConvolutionBlur Inheritance Convolution Inheritance NativeFilter

The ConvolutionBlur class is a filter that uses a convolution matrix to blur an image.

The convolution matrix depends on the scale of the filter. Divisor is scale * scale. A scale of 3 would result in this kernel:
[ 1, 2, 1 ]
[ 2, 3, 2 ]
[ 1, 2, 1 ]

Supported formats:


Example 
  
  var filter: ConvolutionBlur = new ConvolutionBlur( 4 );
  
  var video: WebCam = new WebCam( 160, 120 );
  var image: Image = new Image( 160, 120, ImageFormat.RGB );
  
  image.loadBitmapData( video.getCurrentFrame(), true );
  
  filter.apply( image );
