blurY (BlurFilter.blurY property)
public blurY : Number
The amount of vertical blur. Valid values are from 0 to 255 (floating point). The default value
is 4. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more
quickly than other values.
Availability: ActionScript 1.0; Flash Player 8
Example
The following example changes the blurY property on an existing MovieClip instance when a
user clicks it.
import flash.filters.BlurFilter;
var mc:MovieClip = createBlurFilterRectangle("BlurFilterBlurY");
mc.onRelease = function() {
var filter:BlurFilter = this.filters[0];
filter.blurY = 200;
this.filters = new Array(filter);
}
function createBlurFilterRectangle(name:String):MovieClip {
var rect:MovieClip = this.createEmptyMovieClip(name,
this.getNextHighestDepth());
var w:Number = 100;
var h:Number = 100;
rect.beginFill(0x003366);
rect.lineTo(w, 0);
rect.lineTo(w, h);
rect.lineTo(0, h);
rect.lineTo(0, 0);
rect._x = 20;
rect._y = 20;
}
var filter:BlurFilter = new BlurFilter(30, 30, 2);
var filterArray:Array = new Array();
filterArray.push(filter);
rect.filters = filterArray;
return rect;
