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
filtersproperty (inherited from DisplayObject). Setting thefiltersproperty of an object does not modify the object, and you can remove the filter by clearing thefiltersproperty. - 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.
