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 thefilters
property of an object does not modify the object, and you can remove the filter by clearing thefilters
property. - To apply filters to BitmapData objects, use the
BitmapData.applyFilter()
method. CallingapplyFilter()
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.

Constructor.
參數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:
For more information, see the description of the | |
type:String (default = "inner ") — The placement of the bevel effect. Possible values are BitmapFilterType constants:
| |
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.

clone | () | 方法 |
public function clone():BitmapFilter
語言版本: | ActionScript 3.0 |

Returns a copy of this filter object.
傳回值BitmapFilter — A new GradientBevelFilter instance with all the
same properties as the original GradientBevelFilter instance.
