The ColorMatrixFilter class lets you apply a 4 x 5 matrix transformation on the RGBA color and alpha values of every pixel in the input image to produce a result with a new set of RGBA color and alpha values. It allows saturation changes, hue rotation, luminance to alpha, and various other effects. You can apply the filter to any display object (that is, objects that inherit from the DisplayObject class), such as MovieClip, SimpleButton, TextField, and Video objects, as well as to BitmapData objects.

matrix

屬性

matrix:Object

語言版本:

ActionScript 3.0

產品版本:

Flex 4

執行階段版本:

Flash Player 10, AIR 1.5

A comma delimited list of 20 doubles that comprise a 4x5 matrix applied to the rendered element. The matrix is in row major order -- that is, the first five elements are multipled by the vector [srcR,srcG,srcB,srcA,1] to determine the output red value, the second five determine the output green value, etc.

The value must either be an array or comma delimited string of 20 numbers.

預設值為 [1,0,0,0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,1,0]。

實作
public function get matrix():Object
public function set matrix(value:Object):void
