| Package | com.yworks.canvas.drawing |
| Interface | public interface IAdvancedStroke extends mx.graphics.IStroke |
| Implementors | AdvancedStroke |
IStroke that allows for custom stroke rendering.
If applyStroke is called on a YGraphics instance and
an IAdvancedStroke is passed, the corresponding draw methods of the stroke will
be called by YGraphics when the YGraphics drawing methods are called.
In addition to the YGraphics instance, a Graphics instance is passed
that should be used by the stroke implementations to perform the actual drawing.
| Method | Defined By | ||
|---|---|---|---|
drawCurve(currentX:Number, currentY:Number, toX:Number, toY:Number, cx:Number, cy:Number, graphics:YGraphics, targetGraphics:Graphics):void
Draw a quadratic bezier curve from (x0,y0) to (x1,y1) using the control
point at (cx,cy). | IAdvancedStroke | ||
drawLine(x0:Number, y0:Number, x1:Number, y1:Number, graphics:YGraphics, targetGraphics:Graphics):void
Draw a straight line from the current graphics location to (toX,toY)
| IAdvancedStroke | ||
Draw a path. | IAdvancedStroke | ||
Reset the stroke state. | IAdvancedStroke | ||
| drawCurve | () | method |
public function drawCurve(currentX:Number, currentY:Number, toX:Number, toY:Number, cx:Number, cy:Number, graphics:YGraphics, targetGraphics:Graphics):void
Draw a quadratic bezier curve from (x0,y0) to (x1,y1) using the control
point at (cx,cy).
Note that no moveTo operation should be called on the targetGraphics that moves
to (currentX,currentY). The targetGraphics current location will already be set to (x0,y0).
Parameters
currentX:Number — The x-coordinate of the current graphics location (the first anchor point of the curve)
| |
currentY:Number — The y-coordinate of the current graphics location (the first anchor point of the curve)
| |
toX:Number — The x-coordinate of the curve's second anchor point
| |
toY:Number — The y-coordinate of the curve's second anchor point
| |
cx:Number — The x-coordinate of the curve's the control point
| |
cy:Number — The y-coordinate of the curve's control point
| |
graphics:YGraphics — The YGraphics instance that wants to draw the curve
| |
targetGraphics:Graphics — The graphics instance that should be used for actual drawing. The current location of the graphics instance
is already set to currentX,currentY
|
| drawLine | () | method |
public function drawLine(x0:Number, y0:Number, x1:Number, y1:Number, graphics:YGraphics, targetGraphics:Graphics):void
Draw a straight line from the current graphics location to (toX,toY)
Parameters
x0:Number — The x-coordinate of the current graphics location
| |
y0:Number — The y-coordinate of the current graphics location
| |
x1:Number — The x-coordinate of the line's end point
| |
y1:Number — The y-coordinate of the line's end point
| |
graphics:YGraphics — The YGraphics instance that wants to draw the line
| |
targetGraphics:Graphics — The graphics instance that should be used for actual drawing. The current location of the graphics instance
is already set to currentX,currentY
|
| drawPath | () | method |
public function drawPath(path:GeneralPath, graphics:YGraphics, targetGraphics:Graphics):voidDraw a path.
Parameters
path:GeneralPath — The path to be drawn
| |
graphics:YGraphics — The YGraphics instance that wants to draw the path
| |
targetGraphics:Graphics — The graphics instance that should be used for actual drawing
|
| reset | () | method |
public function reset(graphics:YGraphics, targetGraphics:Graphics):voidReset the stroke state.
This is called by YGraphics when a moveTo or endFill is
requested.
Parameters
graphics:YGraphics — The YGraphics instance that wants to reset the stroke state.
| |
targetGraphics:Graphics — The graphics instance that should be used for actual drawing
