屬性詳細資訊

angle

屬性

angle:Number

已不建議使用: 請使用 rotation

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

By default, the LinearGradientStroke defines a transition from left to right across the control. Use the angle property to control the transition direction. For example, a value of 180.0 causes the transition to occur from right to left, rather than from left to right.

預設值為 0.0。

實作
public function get angle():Number
public function set angle(value:Number):void

compoundTransform

屬性

protected var compoundTransform:mx.geom:CompoundTransform

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Holds the matrix and the convenience transform properties (x, y, and rotation). The compoundTransform is only created when the matrix property is set.

entries

屬性

entries:Array

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

An Array of GradientEntry objects defining the fill patterns for the gradient fill.

預設值為 []。

此屬性可以做為資料繫結的來源。一旦修改此屬性，將傳送 propertyChange 事件。

實作
public function get entries():Array
public function set entries(value:Array):void

interpolationMethod

屬性

interpolationMethod:String

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

A value from the InterpolationMethod class that specifies which interpolation method to use.

Valid values are InterpolationMethod.LINEAR_RGB and InterpolationMethod.RGB.

預設值為 InterpolationMethod.RGB。

實作
public function get interpolationMethod():String
public function set interpolationMethod(value:String):void

matrix

屬性

matrix:Matrix

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

An array of values used for matrix transformation.

The gradient scaleX and scaleY properties represent pixels while the Matrix scale properties represent multipliers. Thus they are not compatible. Another difference is the most of the transform properties (x, y, scaleX, and scaleY) support NaN values while the matrix does not. A NaN value means that the gradient will choose an appropriate value.

The scaleX and scaleY properties can not be represented by the matrix. Once the matrix is set, scaleX and scaleY can no longer be set. Also, x and y can not be set to NaN. The matrix can be set back to null which also resets all of the convenience transform properties back to their default values.

If the matrix is set, then the gradient draw logic will scale the gradient to fit the bounds of the graphic element. It will then position the gradient in the upper left corner of the graphic element. Finally, it will apply the matrix transformations.

By default, the LinearGradientStroke defines a transition from left to right across the control. Use the rotation property to control the transition direction. For example, a value of 180.0 causes the transition to occur from right to left, rather than from left to right.

預設值為 null。

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

rotation

屬性

rotation:Number

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:
