Property Detail

scaleX

property

scaleX:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The horizontal scale of the gradient transform, which defines the width of the (unrotated) gradient

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

Constructor

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

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.NONE`.

	`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`.

Method Detail

apply

()

method

override public function apply(graphics:Graphics, targetBounds:Rectangle, targetOrigin:Point):void

Applies the properties to the specified Graphics object.

Parameters

	`graphics:Graphics` — The Graphics object to apply the properties to.

	`targetBounds:Rectangle` — The bounds of the shape that the stroke is applied to.

	`targetOrigin:Point` — The Point that defines the origin (0,0) of the shape in the coordinate system of target.
