To create a new filter, use the constructor new BevelFilter()
.
The use of filters depends on the object to which you apply the filter:
- To apply filters to movie clips, text fields, buttons, and video, use the
filters
property (inherited from DisplayObject). 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 value of the cacheAsBitmap
property of the
object is set to true
. If you remove 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 the scaleX
and scaleY
properties are
not set to 100%), 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.) If, for example, 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.

angle | proprietà |
angle:Number
Versione linguaggio: | ActionScript 3.0 |
Versione prodotto: | Flex 4 |
Versioni runtime: | Flash Player 10, AIR 1.5 |
The angle of the bevel, in degrees. Valid values are from 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 the distance property is set to 0, the effect is not offset from the object and, therefore, the angle property has no effect.
Il valore predefinito è 45.

Constructor.
Parametridistance:Number (default = 4.0 ) — The offset distance of the bevel, in pixels (floating point).
| |
angle:Number (default = 45 ) — The angle of the bevel, from 0 to 360 degrees.
| |
highlightColor:uint (default = 0xFFFFFF ) — The highlight color of the bevel, 0xRRGGBB.
| |
highlightAlpha:Number (default = 1.0 ) — The alpha transparency value of the highlight color. Valid values are 0.0 to
1.0. For example,
.25 sets a transparency value of 25%.
| |
shadowColor:uint (default = 0x000000 ) — The shadow color of the bevel, 0xRRGGBB.
| |
shadowAlpha:Number (default = 1.0 ) — The alpha transparency value of the shadow color. Valid values are 0.0 to 1.0. For example,
.25 sets a transparency value of 25%.
| |
blurX:Number (default = 4.0 ) — The amount of horizontal blur in pixels. Valid values are 0 to 255.0 (floating point).
| |
blurY:Number (default = 4.0 ) — The amount of vertical blur in pixels. Valid values are 0 to 255.0 (floating point).
| |
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 255.0.
| |
quality:int (default = 1 ) — The quality of the bevel. Valid values are 0 to 15, but for most applications,
you can use flash.filters.BitmapFilterQuality constants:
Filters with lower values render faster. You can use the other available numeric values to achieve different effects. | |
type:String (default = "inner ") — The type of bevel. Valid values are flash.filters.BitmapFilterType constants:
BitmapFilterType.INNER , BitmapFilterType.OUTER , or
BitmapFilterType.FULL .
| |
knockout:Boolean (default = false ) — Applies a knockout effect (true ), which effectively
makes the object's fill transparent and reveals the background color of the document.
