The use of filters depends on the object to which you apply the filter:
- To apply filters to display objects 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
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 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.

The angle of the bevel. 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.
기본값: 45.

Indicates whether or not the object is hidden.
The value true
indicates that the
object itself is not drawn; only the shadow is visible.
The default is false

The value true
indicates an inner glow.
The default is false
that creates an outer glow

Constructor.
매개 변수distance:Number (default = 4.0 ) — Offset distance for the shadow, in pixels.
| |
angle:Number (default = 45 ) — Angle of the shadow, 0 to 360 degrees (floating point).
| |
color:uint (default = 0 ) — Color of the shadow, in hexadecimal format
0xRRGGBB. The default value is 0x000000.
| |
alpha:Number (default = 1.0 ) — Alpha transparency value for 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 ) — Amount of horizontal blur. Valid values are 0 to 255.0 (floating point).
| |
blurY:Number (default = 4.0 ) — Amount of vertical blur. Valid values are 0 to 255.0 (floating point).
| |
strength:Number (default = 1.0 ) — The strength of the imprint or spread. The higher the value,
the more color is imprinted and the stronger the contrast between the shadow and the background.
Valid values are 0 to 255.0.
| |
quality:int (default = 1 ) — The number of times to apply the filter. Use the BitmapFilterQuality constants:
For more information about these values, see the | |
inner:Boolean (default = false ) — Indicates whether or not the shadow is an inner shadow. A value of true specifies
an inner shadow. A value of false specifies an outer shadow (a
shadow around the outer edges of the object).
| |
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.
| |
hideObject:Boolean (default = false ) — Indicates whether or not the object is hidden. A value of true
indicates that the object itself is not drawn; only the shadow is visible.
