Glow filter
Flash Player 9 and later, Adobe AIR 1.0 and
later
|
The GlowFilter class applies a lighting effect to display objects,
making it appear that a light is being shined up from underneath
the object to create a soft glow.
Similar to the drop shadow filter, the glow filter includes properties
to modify the distance, angle, and color of the light source to
produce varying effects. The GlowFilter also has several options
for modifying the style of the glow, including inner or outer glow
and knockout mode.
The following code creates a cross using the Sprite class and
applies a glow filter to it:
import flash.display.Sprite;
import flash.filters.BitmapFilterQuality;
import flash.filters.GlowFilter;
// Create a cross graphic.
var crossGraphic:Sprite = new Sprite();
crossGraphic.graphics.lineStyle();
crossGraphic.graphics.beginFill(0xCCCC00);
crossGraphic.graphics.drawRect(60, 90, 100, 20);
crossGraphic.graphics.drawRect(100, 50, 20, 100);
crossGraphic.graphics.endFill();
addChild(crossGraphic);
// Apply the glow filter to the cross shape.
var glow:GlowFilter = new GlowFilter();
glow.color = 0x009922;
glow.alpha = 1;
glow.blurX = 25;
glow.blurY = 25;
glow.quality = BitmapFilterQuality.MEDIUM;
crossGraphic.filters = [glow];
