Property Detail
angleproperty
angle:Number

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.

The default value is 0.0.



Implementation
    public function get angle():Number
    public function set angle(value:Number):void
capsproperty 
caps:String

A value from the CapsStyle class that specifies the type of caps at the end of lines.

Valid values are CapsStyle.NONE, CapsStyle.ROUND, and CapsStyle.SQUARE. A null value is equivalent to CapsStyle.ROUND.

The default value is null.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get caps():String
    public function set caps(value:String):void
interpolationMethodproperty 
interpolationMethod:String

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

Valid values are InterpolationMethod.LINEAR_RGB and InterpolationMethod.RGB.

The default value is InterpolationMethod.RGB.



Implementation
    public function get interpolationMethod():String
    public function set interpolationMethod(value:String):void
jointsproperty 
joints:String

A value from the JointStyle class that specifies the type of joint appearance used at angles.

Valid values are JointStyle.BEVEL, JointStyle.MITER, and JointStyle.ROUND. A null value is equivalent to JoinStyle.ROUND.

The default value is null.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get joints():String
    public function set joints(value:String):void
miterLimitproperty 
miterLimit:Number

A number that indicates the limit at which a miter is cut off.

Valid values range from 0 to 255 (and values outside of that range are rounded to 0 or 255).

This value is only used if the jointStyle is set to JointStyle.MITER.

The miterLimit value represents the length that a miter can extend beyond the point at which the lines meet to form a joint. The value expresses a factor of the line thickness. For example, with a miterLimit factor of 2.5 and a thickness of 10 pixels, the miter is cut off at 25 pixels.

The default value is 0.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get miterLimit():Number
    public function set miterLimit(value:Number):void
pixelHintingproperty 
pixelHinting:Boolean

A Boolean value that specifies whether to hint strokes to full pixels.

This affects both the position of anchors of a curve and the line stroke size itself.

With pixelHinting set to true, Flash Player and AIR hint line widths to full pixel widths. With pixelHinting set to false, disjoints can appear for curves and straight lines.

The default value is false.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get pixelHinting():Boolean
    public function set pixelHinting(value:Boolean):void
scaleModeproperty 
scaleMode:String

A value from the LineScaleMode class that specifies which scale mode to use. Value valids are:

The default value is LineScaleMode.NORMAL.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get scaleMode():String
    public function set scaleMode(value:String):void
spreadMethodproperty 
spreadMethod:String

A value from the SpreadMethod class that specifies which spread method to use.

Value values are SpreadMethod.PAD, SpreadMethod.REFLECT, and SpreadMethod.REPEAT.

The default value is SpreadMethod.PAD.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get spreadMethod():String
    public function set spreadMethod(value:String):void
weightproperty 
weight:Number

The line weight, in pixels. For many charts, the default value is 1 pixel.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get weight():Number
    public function set weight(value:Number):void
Constructor Detail
LinearGradientStroke()Constructor
public function LinearGradientStroke(weight:Number = 0, pixelHinting:Boolean = false, scaleMode:String = "normal", caps:String = null, joints:String = null, miterLimit:Number = 0)

Constructor.

Parameters
weight:Number (default = 0) — Specifies the line weight, in pixels. This parameter is optional, with a default value of 0.
 
pixelHinting:Boolean (default = false) — A Boolean value that specifies whether to hint strokes to full pixels. This affects both the position of anchors of a curve and the line stroke size itself. With pixelHinting set to true, Flash Player and AIR hint line widths to full pixel widths. With pixelHinting set to false, disjoints can appear for curves and straight lines. This parameter is optional, with a default value of false.
 
scaleMode:String (default = "normal") — A value from the LineScaleMode class that specifies which scale mode to use. Valid values are LineScaleMode.HORIZONTAL, LineScaleMode.NONE, LineScaleMode.NORMAL, and LineScaleMode.VERTICAL. This parameter is optional, with a default value of LineScaleMode.NORMAL.
 
caps:String (default = null) — A value from the CapsStyle class that specifies the type of caps at the end of lines. Valid values are CapsStyle.NONE, CapsStyle.ROUND, and CapsStyle.SQUARE. A null value is equivalent to CapsStyle.ROUND. This parameter is optional, with a default value of null.
 
joints:String (default = null) — A value from the JointStyle class that specifies the type of joint appearance used at angles. Valid values are JointStyle.BEVEL, JointStyle.MITER, and JointStyle.ROUND. A null value is equivalent to JoinStyle.ROUND. This parameter is optional, with a default value of null.
 
miterLimit:Number (default = 0) — A number that indicates the limit at which a miter is cut off. Valid values range from 1 to 255 (and values outside of that range are rounded to 1 or 255). This value is only used if the jointStyle property is set to miter. The miterLimit value represents the length that a miter can extend beyond the point at which the lines meet to form a joint. The value expresses a factor of the line thickness. For example, with a miterLimit factor of 2.5 and a thickness of 10 pixels, the miter is cut off at 25 pixels. This parameter is optional, with a default value of 0.
Method Detail
apply()method
