BlurFilter constructor
public BlurFilter([blurX:Number], [blurY:Number], [quality:Number])
Initializes the filter with the specified parameters. The default values create a soft, unfocused
image.
Availability: ActionScript 1.0; Flash Player 8
Parameters
blurX:Number [optional] - The amount to blur horizontally. Valid values are from 0 to 255
(floating-point value). 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.
blurY:Number [optional] - The amount to blur vertically. Valid values are from 0 to 255
(floating-point value). 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.
quality:Number [optional] - The number of times to apply the filter. The default value is 1,
which is equivalent to low quality. A value of 2 is medium quality, and a value of 3 is high
quality and approximates a Gaussian blur.
Example
The following example instantiates a new BlurFilter constructor and applies it to a flat,
rectangular shape:
import flash.filters.BlurFilter;
var rect:MovieClip = createRectangle(100, 100, 0x003366,
"BlurFilterExample");
var blurX:Number = 30;
var blurY:Number = 30;
var quality:Number = 3;
var filter:BlurFilter = new BlurFilter(blurX, blurY, quality);
var filterArray:Array = new Array();
filterArray.push(filter);
rect.filters = filterArray;
