Classpublic final class GraphicsStroke
InheritanceGraphicsStroke Inheritance Object
Implements IGraphicsStroke, IGraphicsData

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Defines a line style or stroke.

Use a GraphicsStroke object with the Graphics.drawGraphicsData() method. Drawing a GraphicsStroke object is the equivalent of calling one of the methods of the Graphics class that sets the line style, such as the Graphics.lineStyle() method, the Graphics.lineBitmapStyle() method, or the Graphics.lineGradientStyle() method.

Property Detail

caps

property
caps:String

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Specifies the type of caps at the end of lines. Valid values are: CapsStyle.NONE, CapsStyle.ROUND, and CapsStyle.SQUARE. If a value is not indicated, Flash uses round caps.

For example, the following illustrations show the different capsStyle settings. For each setting, the illustration shows a blue line with a thickness of 30 (for which the capsStyle applies), and a superimposed black line with a thickness of 1 (for which no capsStyle applies):

NONE, ROUND, and SQUARE



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

Related API Elements

fill

property 
public var fill:IGraphicsFill

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Specifies the instance containing data for filling a stroke. An IGraphicsFill instance can represent a series of fill commands.

Related API Elements

joints

property 
joints:String

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Specifies the type of joint appearance used at angles. Valid values are: JointStyle.BEVEL, JointStyle.MITER, and JointStyle.ROUND. If a value is not indicated, Flash uses round joints.

For example, the following illustrations show the different joints settings. For each setting, the illustration shows an angled blue line with a thickness of 30 (for which the jointStyle applies), and a superimposed angled black line with a thickness of 1 (for which no jointStyle applies):

MITER, ROUND, and BEVEL

Note: For joints set to JointStyle.MITER, you can use the miterLimit parameter to limit the length of the miter.



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

Related API Elements

miterLimit

property 
public var miterLimit:Number

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Indicates the limit at which a miter is cut off. Valid values range from 1 to 255 (and values outside that range are rounded to 1 or 255). This value is only used if the jointStyle 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.

For example, consider the following angled lines, each drawn with a thickness of 20, but with miterLimit set to 1, 2, and 4. Superimposed are black reference lines showing the meeting points of the joints:

lines with miterLimit set to 1, 2, and 4

Notice that a given miterLimit value has a specific maximum angle for which the miter is cut off. The following table lists some examples:

miterLimit value:Angles smaller than this are cut off:
1.41490 degrees
260 degrees
430 degrees
815 degrees

pixelHinting

property 
public var pixelHinting:Boolean

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

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 hints line widths to full pixel widths. With pixelHinting set to false, disjoints can appear for curves and straight lines. For example, the following illustrations show how Flash Player renders two rounded rectangles that are identical, except that the pixelHinting parameter used in the lineStyle() method is set differently (the images are scaled by 200%, to emphasize the difference):

pixelHinting false and pixelHinting true

scaleMode

property 
scaleMode:String

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Specifies the stroke thickness scaling. Valid values 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. For example, consider the following circles, drawn with a one-pixel line, and each with the scaleMode parameter set to LineScaleMode.VERTICAL. The circle on the left is scaled vertically only, and the circle on the right is scaled both vertically and horizontally:

    A circle scaled vertically, and a circle scaled both vertically and horizontally.

  • LineScaleMode.HORIZONTAL—Do not scale the line thickness if the object is scaled horizontally only. For example, consider the following circles, drawn with a one-pixel line, and each with the scaleMode parameter set to LineScaleMode.HORIZONTAL. The circle on the left is scaled horizontally only, and the circle on the right is scaled both vertically and horizontally:

    A circle scaled horizontally, and a circle scaled both vertically and horizontally.



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

Related API Elements

thickness

property 
public var thickness:Number

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Indicates the thickness of the line in points; valid values are 0-255. If a number is not specified, or if the parameter is undefined, a line is not drawn. If a value of less than 0 is passed, the default is 0. The value 0 indicates hairline thickness; the maximum thickness is 255. If a value greater than 255 is passed, the default is 255.

Constructor Detail

thickness:Number (default = NaN) — An integer that indicates the thickness of the line in points; valid values are 0-255. If a number is not specified, or if the parameter is undefined, a line is not drawn. If a value of less than 0 is passed, the default is 0. The value 0 indicates hairline thickness; the maximum thickness is 255. If a value greater than 255 is passed, the default is 255.
 
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 hints line widths to full pixel widths. With pixelHinting set to false, disjoints can appear for curves and straight lines. For example, the following illustrations show how Flash Player renders two rounded rectangles that are identical, except that the pixelHinting parameter used in the lineStyle() method is set differently (the images are scaled by 200%, to emphasize the difference):

pixelHinting false and pixelHinting true

If a value is not supplied, the line does not use pixel hinting.

 
scaleMode:String (default = "normal") — A value from the LineScaleMode class that specifies which scale mode to use:
  • 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. For example, consider the following circles, drawn with a one-pixel line, and each with the scaleMode parameter set to LineScaleMode.VERTICAL. The circle on the left is scaled vertically only, and the circle on the right is scaled both vertically and horizontally:

    A circle scaled vertically, and a circle scaled both vertically and horizontally.

  • LineScaleMode.HORIZONTAL—Do not scale the line thickness if the object is scaled horizontally only. For example, consider the following circles, drawn with a one-pixel line, and each with the scaleMode parameter set to LineScaleMode.HORIZONTAL. The circle on the left is scaled horizontally only, and the circle on the right is scaled both vertically and horizontally:

    A circle scaled horizontally, and a circle scaled both vertically and horizontally.

 
caps:String (default = "none") — 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. If a value is not indicated, Flash uses round caps.

For example, the following illustrations show the different capsStyle settings. For each setting, the illustration shows a blue line with a thickness of 30 (for which the capsStyle applies), and a superimposed black line with a thickness of 1 (for which no capsStyle applies):

NONE, ROUND, and SQUARE

 
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. If a value is not indicated, Flash uses round joints.

For example, the following illustrations show the different joints settings. For each setting, the illustration shows an angled blue line with a thickness of 30 (for which the jointStyle applies), and a superimposed angled black line with a thickness of 1 (for which no jointStyle applies):

MITER, ROUND, and BEVEL

Note: For joints set to JointStyle.MITER, you can use the miterLimit parameter to limit the length of the miter.

 
miterLimit:Number (default = 3.0) — A number that indicates the limit at which a miter is cut off. Valid values range from 1 to 255 (and values outside that range are rounded to 1 or 255). This value is only used if the jointStyle 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.

For example, consider the following angled lines, each drawn with a thickness of 20, but with miterLimit set to 1, 2, and 4. Superimposed are black reference lines showing the meeting points of the joints:

lines with miterLimit set to 1, 2, and 4

Notice that a given miterLimit value has a specific maximum angle for which the miter is cut off. The following table lists some examples:

miterLimit value:Angles smaller than this are cut off:
1.41490 degrees
260 degrees
430 degrees
815 degrees
 
fill:IGraphicsFill (default = null) — An IGraphicsFill instance containing data for filling a stroke. An IGraphicsFill instance can represent a series of fill commands.
