The GlowFilter class lets you apply a glow effect to display objects. You have several options for the style of the glow, including inner or outer glow and knockout mode. The glow filter is similar to the drop shadow filter with the distance and angle properties of the drop shadow filter set to 0. You can apply the filter to any display object (that is, objects that inherit from the DisplayObject class), such as MovieClip, SimpleButton, TextField, and Video objects, as well as to BitmapData objects.

The use of filters depends on the object to which you apply the filter:

To apply filters to display objects, use the filters property (inherited from DisplayObject). Setting the filters property of an object does not modify the object, and you can remove the filter by clearing the filters property.
To apply filters to BitmapData objects, use the BitmapData.applyFilter() method. Calling applyFilter() on a BitmapData object takes the source BitmapData object and the filter object and generates a filtered image as a result.

If you apply a filter to a display object, the cacheAsBitmap property of the display object is set to true. If you clear all filters, the original value of cacheAsBitmap is restored.

This filter supports Stage scaling. However, it does not support general scaling, rotation, and skewing. If the object itself is scaled (if scaleX and scaleY are set to a value other than 1.0), the filter is not scaled. It is scaled only when the user zooms in on the Stage.

A filter is not applied if the resulting image exceeds the maximum dimensions. In AIR 1.5 and Flash Player 10, the maximum is 8,191 pixels in width or height, and the total number of pixels cannot exceed 16,777,215 pixels. (So, if an image is 8,191 pixels wide, it can only be 2,048 pixels high.) For example, if you zoom in on a large movie clip with a filter applied, the filter is turned off if the resulting image exceeds the maximum dimensions.

alpha

속성

alpha:Number

언어 버전:

ActionScript 3.0

제품 버전:

Flex 4

런타임 버전:

Flash Player 10, AIR 1.5

The alpha transparency value for the color. Valid values are 0 to 1. For example, .25 sets a transparency value of 25%.

기본값: 1.

구현
public function get alpha():Number
public function set alpha(value:Number):void

color

속성

color:uint

언어 버전:

ActionScript 3.0

제품 버전:

Flex 4

런타임 버전:

Flash Player 10, AIR 1.5

The color of the glow. Valid values are in the hexadecimal format 0xRRGGBB.

기본값: 0xFF0000.

구현
public function get color():uint
public function set color(value:uint):void

inner

속성

inner:Boolean

언어 버전:

ActionScript 3.0

제품 버전:

Flex 4

런타임 버전:

Flash Player 10, AIR 1.5

Specifies whether the glow is an inner glow. The value true indicates an inner glow. The default is false, meaning an outer glow (a glow around the outer edges of the object).

기본값: false.

구현
public function get inner():Boolean
public function set inner(value:Boolean):void

Constructor.

매개 변수

	`color:uint` (default = `0xFF0000`) — The color of the glow, in the hexadecimal format 0xRRGGBB. The default value is 0xFF0000.

	`alpha:Number` (default = `1.0`) — The alpha transparency value for the color. Valid values are 0 to 1. For example, .25 sets a transparency value of 25%.

	`blurX:Number` (default = `4.0`) — The amount of horizontal blur. Valid values are 0 to 255 (floating point). 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` (default = `4.0`) — The amount of vertical blur. Valid values are 0 to 255 (floating point). Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

	`strength:Number` (default = `1`) — The strength of the imprint or spread. The higher the value, the more color is imprinted and the stronger the contrast between the glow and the background. Valid values are 0 to 255.

	`quality:int` (default = `1`) — The number of times to apply the filter. Use the BitmapFilterQuality constants: `BitmapFilterQuality.LOW` `BitmapFilterQuality.MEDIUM` `BitmapFilterQuality.HIGH` For more information, see the description of the `quality` property.

	`inner:Boolean` (default = `false`) — Specifies whether the glow is an inner glow. The value `true` specifies an inner glow. The value `false` specifies an outer glow (a glow around the outer edges of the object).

	`knockout:Boolean` (default = `false`) — Specifies whether the object has a knockout effect. The value `true` makes the object's fill transparent and reveals the background color of the document.
