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

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 0 to 255 (and values outside of that range are rounded to 0 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: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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.

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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.
