final class GraphicsStroke
package openfl.display
implements IGraphicsStroke, IGraphicsData
Available on all platforms
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.

Constructor
new(?thickness:Float, pixelHinting:Bool = false, scaleMode:LineScaleMode = LineScaleMode.NORMAL, caps:CapsStyle = CapsStyle.NONE, joints:JointStyle = JointStyle.ROUND, miterLimit:Float = 3, ?fill:IGraphicsFill)
Creates a new GraphicsStroke object.
Parameters:
pixelHinting | 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 If a value is not supplied, the line does not use pixel hinting. |
|---|---|
scaleMode | A value from the LineScaleMode class that specifies which scale mode to use:
|
caps | A value from the CapsStyle class that specifies the
type of caps at the end of lines. Valid values are:

joints | A value from the JointStyle class that specifies the
type of joint appearance used at angles. Valid values

Variables
caps:CapsStyle
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):
fill:IGraphicsFill
Specifies the instance containing data for filling a stroke. An IGraphicsFill instance can represent a series of fill commands.
joints:JointStyle
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):
Note: For joints set to
JointStyle.MITER, you can use the miterLimit
parameter to limit the length of the miter.
miterLimit:Float
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:
Notice that a given miterLimit value has a specific
maximum angle for which the miter is cut off. The following table lists
some examples:
pixelHinting:Bool
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):
scaleMode:LineScaleMode
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 thescaleModeparameter set toLineScaleMode.VERTICAL. The circle on the left is scaled vertically only, and the circle on the right is 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 thescaleModeparameter set toLineScaleMode.HORIZONTAL. The circle on the left is scaled horizontally only, and the circle on the right is scaled both vertically and horizontally:
thickness:Float
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.
