Property Detail

angle

property
angle:Number

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

The angle, in degrees. Valid values are 0 to 360. The angle value represents the angle of the theoretical light source falling on the object and determines the placement of the effect relative to the object. If distance is set to 0, the effect is not offset from the object, and therefore the angle property has no effect.

The default value is 45.



Implementation
    public function get angle():Number
    public function set angle(value:Number):void

distance

property 
distance:Number

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

The offset distance of the glow.

The default value is 4.0.



Implementation
    public function get distance():Number
    public function set distance(value:Number):void

entries

property 
entries:Array

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

An Array of GradientEntry objects defining the fill patterns for the gradient fill.

The default value is [].

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get entries():Array
    public function set entries(value:Array):void

type

property 
type:String

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

The placement of the filter effect. Possible values are flash.filters.BitmapFilterType constants:

  • BitmapFilterType.OUTER - Glow on the outer edge of the object.
  • BitmapFilterType.INNER - Glow on the inner edge of the object.
  • BitmapFilterType.FULL - Glow on top of the object.

The default value is BitmapFilterType.INNER.



Implementation
    public function get type():String
    public function set type(value:String):void

Constructor Detail

GradientFilter

()Constructor
public function GradientFilter(colors:Array = null, alphas:Array = null, ratios:Array = null)

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Constructor.

Parameters
colors:Array (default = null) — An array of RGB hexadecimal color values to use in the gradient. For example, red is 0xFF0000, blue is 0x0000FF, and so on.
 
alphas:Array (default = null) — An array of alpha transparency values for the corresponding colors in the colors array. Valid values for each element in the array are 0 to 1. For example, .25 sets a transparency value of 25%.
 
ratios:Array (default = null) — An array of color distribution ratios; valid values are 0 to 255.
