The GradientBevelFilter class lets you apply a gradient bevel effect to display objects. A gradient bevel is a beveled edge, enhanced with gradient color, on the outside, inside, or top of an object. Beveled edges make objects look three-dimensional. 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. 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 effect 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.

public function GradientBevelFilter(distance:Number = 4.0, angle:Number = 45, colors:Array = null, alphas:Array = null, ratios:Array = null, blurX:Number = 4.0, blurY:Number = 4.0, strength:Number = 1, quality:int = 1, type:String = "inner", knockout:Boolean = false)

Constructor.

매개 변수

	`distance:Number` (default = `4.0`) — The offset distance. Valid values are 0 to 8.

	`angle:Number` (default = `45`) — The angle, in degrees. Valid values are 0 to 360.

	`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.

	`blurX:Number` (default = `4.0`) — The amount of horizontal blur. Valid values are 0 to 255. A blur of 1 or less means that the original image is copied as is. The default value is 4. 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. A blur of 1 or less means that the original image is copied as is. 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 bevel and the background. Valid values are 0 to 255. A value of 0 means that the filter is not applied.

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

	`type:String` (default = "`inner`") — The placement of the bevel effect. Possible values are BitmapFilterType constants: `BitmapFilterType.OUTER` — Bevel on the outer edge of the object `BitmapFilterType.INNER` — Bevel on the inner edge of the object `BitmapFilterType.FULL` — Bevel on top of the object

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