---|---|---|---|
Canvas() Creates a new (empty) Canvas. | Canvas | ||
addEventListener(type:String, listener:Function):void [override] Registers an event listener at a certain object. | DisplayObject | ||
alignPivot(hAlign:String = center, vAlign:String = center):void Moves the pivot point to a certain position within the local coordinate system
of the object. | DisplayObject | ||
beginFill(color:uint = 0xffffff, alpha:Number = 1.0):void Specifies a simple one-color fill that subsequent calls to drawing methods
(such as drawCircle()) will use. | Canvas | ||
clear():void Removes all existing vertices. | Canvas | ||
dispatchEvent(event:Event):void [override] | DisplayObject | ||
dispatchEventWith(type:String, bubbles:Boolean = false, data:Object = null):void Dispatches an event with the given parameters to all objects that have registered
listeners for the given type. | EventDispatcher | ||
dispose():void [override] Disposes all resources of the display object. | Canvas | ||
drawCircle(x:Number, y:Number, radius:Number):void Draws a circle. | Canvas | ||
drawEllipse(x:Number, y:Number, width:Number, height:Number):void Draws an ellipse. | Canvas | ||
drawPolygon(polygon:Polygon):void Draws an arbitrary polygon. | Canvas | ||
drawRectangle(x:Number, y:Number, width:Number, height:Number):void Draws a rectangle. | Canvas | ||
endFill():void Resets the color to 'white' and alpha to '1'. | Canvas | ||
getBounds(targetSpace:DisplayObject, resultRect:Rectangle = null):Rectangle [override] Returns a rectangle that completely encloses the object as it appears in another
coordinate system. | Canvas | ||
getTransformationMatrix(targetSpace:DisplayObject, resultMatrix:Matrix = null):Matrix Creates a matrix that represents the transformation from the local coordinate system
to another. | DisplayObject | ||
getTransformationMatrix3D(targetSpace:DisplayObject, resultMatrix:Matrix3D = null):Matrix3D Creates a matrix that represents the transformation from the local coordinate system
to another. | DisplayObject | ||
globalToLocal(globalPoint:Point, resultPoint:Point = null):Point Transforms a point from global (stage) coordinates to the local coordinate system. | DisplayObject | ||
globalToLocal3D(globalPoint:Point, resultPoint:Vector3D = null):Vector3D Transforms a point from global (stage) coordinates to the 3D local coordinate system. | DisplayObject | ||
hasEventListener(type:String):Boolean Returns if there are listeners registered for a certain event type. | EventDispatcher | ||
hitTest(localPoint:Point, forTouch:Boolean = false):DisplayObject [override] Returns the object that is found topmost beneath a point in local coordinates, or nil if
the test fails. | Canvas | ||
hitTestMask(localPoint:Point):Boolean Checks if a certain point is inside the display object's mask. | DisplayObject | ||
local3DToGlobal(localPoint:Vector3D, resultPoint:Point = null):Point Transforms a 3D point from the local coordinate system to global (stage) coordinates. | DisplayObject | ||
localToGlobal(localPoint:Point, resultPoint:Point = null):Point Transforms a point from the local coordinate system to global (stage) coordinates. | DisplayObject | ||
removeEventListener(type:String, listener:Function):void [override] Removes an event listener from the object. | DisplayObject | ||
removeEventListeners(type:String = null):void [override] Removes all event listeners with a certain type, or all of them if type is null. | DisplayObject | ||
removeFromParent(dispose:Boolean = false):void Removes the object from its parent, if it has one, and optionally disposes it. | DisplayObject | ||
render(support:RenderSupport, parentAlpha:Number):void [override] Renders the display object with the help of a support object. | Canvas |
Canvas | () | Constructor |
public function Canvas()
Creates a new (empty) Canvas. Call one or more of the 'draw' methods to add content.
beginFill | () | method |
public function beginFill(color:uint = 0xffffff, alpha:Number = 1.0):void
Specifies a simple one-color fill that subsequent calls to drawing methods
(such as drawCircle()
) will use.
Parameters
color:uint (default = 0xffffff )
| |
alpha:Number (default = 1.0 )
|
clear | () | method |
public function clear():void
Removes all existing vertices.
dispose | () | method |
override public function dispose():void
Disposes all resources of the display object. GPU buffers are released, event listeners are removed, filters and masks are disposed.
drawCircle | () | method |
public function drawCircle(x:Number, y:Number, radius:Number):void
Draws a circle.
Parameters
x:Number | |
y:Number | |
radius:Number |
drawEllipse | () | method |
public function drawEllipse(x:Number, y:Number, width:Number, height:Number):void
Draws an ellipse.
Parameters
x:Number | |
y:Number | |
width:Number | |
height:Number |
drawPolygon | () | method |
public function drawPolygon(polygon:Polygon):void
Draws an arbitrary polygon.
Parameters
polygon:Polygon |
drawRectangle | () | method |
public function drawRectangle(x:Number, y:Number, width:Number, height:Number):void
Draws a rectangle.
Parameters
x:Number | |
y:Number | |
width:Number | |
height:Number |
endFill | () | method |
public function endFill():void
Resets the color to 'white' and alpha to '1'.
getBounds | () | method |
override public function getBounds(targetSpace:DisplayObject, resultRect:Rectangle = null):Rectangle
Returns a rectangle that completely encloses the object as it appears in another coordinate system. If you pass a 'resultRectangle', the result will be stored in this rectangle instead of creating a new object.
Parameters
targetSpace:DisplayObject | |
resultRect:Rectangle (default = null )
|
Rectangle |
hitTest | () | method |
override public function hitTest(localPoint:Point, forTouch:Boolean = false):DisplayObject
Returns the object that is found topmost beneath a point in local coordinates, or nil if the test fails. If "forTouch" is true, untouchable and invisible objects will cause the test to fail.
Parameters
localPoint:Point | |
forTouch:Boolean (default = false )
|
DisplayObject |
render | () | method |
override public function render(support:RenderSupport, parentAlpha:Number):void
Renders the display object with the help of a support object. Never call this method directly, except from within another render method.
Parameters
support:RenderSupport — Provides utility functions for rendering.
| |
parentAlpha:Number — The accumulated alpha value from the object's parent up to the stage. |
