To create a convolution filter, use the syntax new ConvolutionFilter().
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 clear all filters, the original value of
cacheAsBitmap is restored.
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 maximum dimensions.

alpha | 속성 |
bias | 속성 |
bias:Number| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4 |
| 런타임 버전: | Flash Player 10, AIR 1.5 |
The amount of bias to add to the result of the matrix transformation. The bias increases the color value of each channel, so that dark colors appear brighter.
기본값: 0.
구현
public function get bias():Number public function set bias(value:Number):voidclamp | 속성 |
clamp:Boolean| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4 |
| 런타임 버전: | Flash Player 10, AIR 1.5 |
Indicates whether the image should be clamped. For pixels off the source image, a value of true indicates that the input image is extended along each of its borders as necessary by duplicating the color values at each respective edge of the input image. A value of false indicates that another color should be used, as specified in the color and alpha properties.
기본값: true.

divisor | 속성 |
divisor:Number| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4 |
| 런타임 버전: | Flash Player 10, AIR 1.5 |
The divisor used during matrix transformation. The default value is 1. A divisor that is the sum of all the matrix values smooths out the overall color intensity of the result. A value of 0 is ignored and the default is used instead.
기본값: 1.0.
구현

matrix:Array| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4 |
| 런타임 버전: | Flash Player 10, AIR 1.5 |
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.
기본값: [].

Indicates if the alpha channel is preserved without the filter effect or if the convolution filter is applied to the alpha channel as well as the color channels. A value of false indicates that the convolution applies to all channels, including the alpha channel. A value of true indicates that the convolution applies only to the color channels.
