quality (BlurFilter.quality property)
public quality : Number
The number of times to perform the blur. Valid values are from 0-15. The default value is 1,
which is equivalent to low quality. A value of 2 is medium quality. A value of 3 is high quality
and approximates a Gaussian blur.
For most applications, a
quality
value of 1, 2, or 3 is sufficient. Although you can use
additional numeric values up to 15 to increase the number of times the blur is applied, thus
getting a more blurred effect, be aware that higher values are rendered more slowly. Instead of
increasing the value of
quality
, you can often get a similar effect, and with faster rendering,
by simply increasing the values of
blurX
and
blurY
.
Availability: ActionScript 1.0; Flash Player 8
Example
The following example creates a rectangle and applies a blur filter with a
quality
value of 1
to the rectangle. When you click the rectangle, the
quality
increases to 3, and the rectangle
becomes more blurry.
import flash.filters.BlurFilter;
var mc:MovieClip = createBlurFilterRectangle("BlurFilterQuality");
mc.onRelease = function() {
var filter:BlurFilter = this.filters[0];
filter.quality = 3;
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, 1);
var filterArray:Array = new Array();
filterArray.push(filter);
rect.filters = filterArray;
return rect;
