Property Detail

caps

property

caps:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Specifies the appearance of the ends of lines.

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

The default value is CapsStyle.ROUND.

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

flash.display.CapStyle

joints

property

joints:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

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 JointStyle.ROUND.

The default value is JointStyle.ROUND.

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

flash.display.JointStyle

miterLimit

property

miterLimit:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

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 JointStyle.MITER.

The value of the miterLimit property 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 3.

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

pixelHinting

property

pixelHinting:Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

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

scaleMode

property

scaleMode:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Specifies which scale mode to use. Value valids are:

LineScaleMode.NORMAL— Always scale the line thickness when the object is scaled (the default).
LineScaleMode.NONE— Never scale the line thickness.
LineScaleMode.VERTICAL— Do not scale the line thickness if the object is scaled vertically only.
LineScaleMode.HORIZONTAL— Do not scale the line thickness if the object is scaled horizontally only.

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

weight

property

weight:Number

Language Version:

ActionScript 3.0

Product Version:

The stroke weight, in pixels.

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

Constructor

public function GradientStroke(weight:Number = 1, pixelHinting:Boolean = false, scaleMode:String = "normal", caps:String = "round", joints:String = "round", miterLimit:Number = 3)

Constructor.

Parameters

	`weight:Number` (default = `1`) — Specifies the line weight, in pixels. This parameter is optional, with a default value of `1`.

	`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 = "`round`") — 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 `CapsStyle.ROUND`.

	`joints:String` (default = "`round`") — 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 `JointStyle.ROUND`. This parameter is optional, with a default value of `JointStyle.ROUND`.

	`miterLimit:Number` (default = `3`) — 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 `3`.
