Demonstrates how aether's ImageEffect may be extended to create visual effects. This effect allows you to use several other subeffects to create a Pointilism effect by applying a pixel dissolve, saturating the image and blurring the result. 

  
          public class @ax-graphic-flex-image-effects-10-Flex-PointillismEffect extends ImageEffect {
  
                  private var _saturation:Number;
                  private var _lightColor:uint;
                  private var _lightAmount:Number;
                  private var _blurAmount:Number;
Constructor. Sets the properties of the effect.
parameter: saturation The amount of saturation to apply to the image.
parameter: lightColor The color of the speckles to use in the dissolve.
parameter: lightAmount The amount of dissolve to apply to the image.
parameter: blurAmount The blur amount to apply to the dissolved image.
parameter: blendMode The blend mode to use when applying the effect.
parameter: alpha The alpha to use when applying the effect. 

  
                  public function @ax-graphic-flex-image-effects-10-Flex-PointillismEffect(
                          saturation:Number=2.2,
                          lightColor:uint=0xFFFFFFFA,
                          lightAmount:Number=.33,
                          blurAmount:Number=5,
                          blendMode:String=null,
                          alpha:Number=1
                  ) {
                          init(blendMode, alpha);
                          _saturation = saturation;
                          _lightColor = lightColor;
                          _lightAmount = lightAmount;
                          _blurAmount = blurAmount;
                  }
Applies the effect to the specified image.
parameter: bitmapData The image to which to apply the effect. 

  
                  override protected function applyEffect(bitmapData:BitmapData):void {
                          new CompositeEffect(
                                  [
                                  new SaturationEffect(_saturation),
                                  new graphic_flex_image_effects_10_Flex_DissolveEffect(_lightAmount, _lightColor),
                                  new BlurEffect(_blurAmount, _blurAmount)
                                  ]
                          ).apply(bitmapData);
                  }
