caps

屬性

caps: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

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.

預設值為 CapsStyle.ROUND。

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。

public function get caps():String
public function set caps(value:String):void

屬性

joints:String

語言版本:

ActionScript 3.0

產品版本:

執行階段版本:

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.

預設值為 JointStyle.ROUND。

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。

miterLimit

屬性

miterLimit:Number

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 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.

預設值為 3。

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 miterLimit():Number
public function set miterLimit(value:Number):void

pixelHinting

屬性

pixelHinting:Boolean

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 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.

預設值為 false。

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 pixelHinting():Boolean
public function set pixelHinting(value:Boolean):void

scaleMode

屬性

scaleMode: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

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.

預設值為 LineScaleMode.NORMAL。

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。

Constructor.

參數

	`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`.
