| Inheritance | ShapePaintable  Object |
| Implements | IPaintable, IBoundsProvider, IHitTestable, IMarqueeTestable |
IPaintable implementations for simple geometric primitives.

intersections with the shape. | ShapePaintable | ||

| fill | property |
fill:IFillThe fill to use for this paintable.

stroke:IStrokeThe stroke to use for this paintable.
public function get stroke():IStroke public function set stroke(value:IStroke):void| calculateBounds | () | method |
public function calculateBounds(scratch:IMutableRectangle, ctx:ICanvasContext):IRectangleReturns a tight rectangular area where the whole rendering would fit into.
Implementations can use the scratch rectangle to put their
results in and return it as the result of the operation.
Client has to always provide a non-null instance as
a parameter. They may however decide to return an internally
cached or dynamically created IRectangle implementation and
disregard the scratch parameter.
If calculating the bounds is too expensive or the painting is not
bound to a certain area, this method may return null.
If nothing is painted, this method should return an empty rectangle, where
either or both the width and height is non-positive or
ImmutableRectangle.Empty.
Parameters
scratch:IMutableRectangle — An instance that can optionally be used to fill with the
corresponding values and be returned
| |
ctx:ICanvasContext — The context to calculate the bounds for (currently not used)
|
IRectangle — The bounds or null to indicate an unbound area
|
| createFixedViewEllipse | () | method |
public static function createFixedViewEllipse(center:IPoint, width:Number, height:Number):ShapePaintable
Creates a dynamic paintable that will use an IPoint to draw
and fill an ellipse in the view coordinate system with a zoom level invariant
width and height.
Drawing in the view coordinate system will make pen widths not scale.
The argument is stored by reference and is queried for each operation.
Thus changing the values of the argument after the creation of the
IPaintable will change the paintable.
Parameters
center:IPoint — he center of the ellipse to draw and fill. The point is
stored in world coordinates, the width and height will be interpreted in the view coordinate system, however.
| |
width:Number — The width of the ellipse.
| |
height:Number — The height of the ellipse.
|
ShapePaintable |
| createPath | () | method |
public static function createPath(path:GeneralPath):ShapePaintableCreates a dynamic paintable that draws a given path.
Parameters
path:GeneralPath — The path to draw.
|
ShapePaintable — A paintable that fills and draws the path.
|
| createPointModelEllipse | () | method |
public static function createPointModelEllipse(center:IPoint, width:Number, height:Number):ShapePaintable
Creates a dynamic paintable that will use an IPoint to draw
and fill an ellipse.
The argument is stored by reference and is queried for each operation.
Thus changing the values of the argument after the creation of the
IPaintable will change the paintable.
Parameters
center:IPoint — The center of the ellipse to draw and fill.
| |
width:Number — The width of the ellipse.
| |
height:Number — The height of the ellipse.
|
ShapePaintable — A paintable that uses the point to draw an ellipse.
|
| createPointModelRectangle | () | method |
public static function createPointModelRectangle(p1:IPoint, p2:IPoint):ShapePaintableCreates a dynamic paintable that will use two points to draw a rectangle in the view.
The argument is stored by reference and is queried for each operation.
Thus changing the values of the argument after the creation of the
IPaintable will change the paintable.
Parameters
p1:IPoint — The first point that defines the bounds of the rectangle.
| |
p2:IPoint — The second point that defines the bounds of the rectangle.
|
ShapePaintable — A paintable that uses the points to draw a rectangle.

| createPolylinePaintable | () | method |
public static function createPolylinePaintable(points:IControlPoints):ShapePaintableParameters
points:IControlPoints |
ShapePaintable |
| createRectModelRectangle | () | method |
public static function createRectModelRectangle(rect:IRectangle):ShapePaintable
Creates a dynamic paintable that will use an IRectangle to draw
and fill a rectangle.
The argument is stored by reference and is queried for each operation.
Thus changing the values of the argument after the creation of the
IPaintable will change the paintable.
Parameters
rect:IRectangle — The rectangle to draw and fill.
|
ShapePaintable — A paintable that uses the rectangle's values to draw a rectangle.
|
| createViewOrientedRectangle | () | method |
public static function createViewOrientedRectangle(orientedRectangle:IOrientedRectangle):ShapePaintable
Creates a dynamic paintable that will use a IOrientedRectangle to draw
and fill an IOrientedRectangle in the view coordinate system.
Drawing in the view coordinate system will make pen widths not scale.
The argument is stored by reference and is queried for each operation.
Thus changing the values of the argument after the creation of the
IPaintable will change the paintable.
Parameters
orientedRectangle:IOrientedRectangle — The oriented rectangle to draw and fill. The rectangle's geometry is
stored in world coordinates, it will be painted in the view coordinate system, however.
|
ShapePaintable — A paintable that uses the rectangle's values to draw an oriented rectangle.
