A geometry object is a type of Degrafa object that enables rendering to a graphics context. Degrafa provides a number of ready-to-use geometry objects. All geometry objects inherit from the Geometry class. All geometry objects have a default data property that can be used for short hand property setting.

Property detail
autoClearGraphicsTargetproperty
autoClearGraphicsTarget:Boolean  [read-write]

When using a graphicsTarget and if this property is set to true the draw phase will clear the graphics context before drawing.

This property can be used as the source for data binding.

Implementation
    public function get autoClearGraphicsTarget():Boolean
    public function set autoClearGraphicsTarget(value:Boolean):void
boundsproperty 
bounds:Rectangle  [read-only]

This property can be used as the source for data binding.

Implementation
    public function get bounds():Rectangle
dataproperty 
data:String  [read-write]

Allows a short hand property setting that is specific to and parsed by each geometry object. Look at the various geometry objects to learn what this setting requires.

This property can be used as the source for data binding.

Implementation
    public function get data():String
    public function set data(value:String):void
fillproperty 
fill:IGraphicsFill  [read-write]

Defines the fill object that will be used for rendering this geometry object.

This property can be used as the source for data binding.

Implementation
    public function get fill():IGraphicsFill
    public function set fill(value:IGraphicsFill):void
geometryproperty 
geometry:Array  [read-write]

A array of IGeometryComposition objects.

Method detail
draw()method
public function draw(graphics:Graphics, rc:Rectangle):void

Begins the draw phase for geometry objects. All geometry objects override this to do their specific rendering.

Parameters
graphics:Graphics — The current context to draw to.
 
rc:Rectangle — A Rectangle object used for fill bounds.
endDraw()method 
public function endDraw(graphics:Graphics):void

Ends the draw phase for geometry objects.

Parameters
graphics:Graphics — The current Graphics context being drawn to.
preDraw()method 
public function preDraw():void

Performs any pre calculation that is required to successfully render this element. Including bounds calculations and lower level drawing command storage. Each geometry object overrides this and is responsible for it's own pre calculation cycle.
