610 ActionScript classes
quality (GlowFilter.quality property)
public quality : Number
The number of times to apply the filter. Valid values are 0 to 15. 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.
Filters with lower values are rendered more quickly.
For most applications, a
quality
value of 1, 2, or 3 is sufficient. Although you can use
additional numeric values up to 15 to achieve different effects, 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 changes the
quality
property on an existing movie clip when a user
clicks it.
import flash.filters.GlowFilter;
var mc:MovieClip = createGlowFilterRectangle("GlowFilterQuality");
mc.onRelease = function() {
var filter:GlowFilter = this.filters[0];
filter.quality = 1;
this.filters = new Array(filter);
}
function createGlowFilterRectangle(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:GlowFilter = new GlowFilter(0x000000, .8, 16, 16, 1, 3, false,
false);
var filterArray:Array = new Array();
filterArray.push(filter);
rect.filters = filterArray;
return rect;
