Method Detail

appendClip(state, clip)

Attaches the specified clipping object to this state.

Parameters:
{createjs.DisplayObject.RenderState} state
{createjs.Renderer.Clip} clip

appendProperties(state, alpha, shadow, composition, visible)

Appends the specified visual properties to this state.

Parameters:
{createjs.DisplayObject.RenderState} state
{number} alpha
{createjs.Shadow} shadow
{number} composition
{boolean} visible

{boolean} contain(point)

Returns whether this state contains the specified point.

Parameters:
{createjs.Point} point

Returns:: {boolean}

copyProperties(state)

Copies the specified rendering property to this property.

Parameters:
{createjs.DisplayObject.RenderState} state

{number} getAlpha()

Retrieves the alpha transparency.

Returns:: {number}

Retrieves the bounding box.

Returns:: {createjs.BoundingBox}

{createjs.Renderer.Clip} getClip()

Retrieves the clipping information.

Returns:: {createjs.Renderer.Clip}

{createjs.Shadow} getShadow()

Retrieves the shadow.

Returns:: {createjs.Shadow}

inflateBox(state)

Inflates the bounding box of this rendering state by the one of the specified state.

Parameters:
{createjs.DisplayObject.RenderState} state

{boolean} isEmpty()

Returns whether this state represents an empty state, i.e. the hosting display object is not createjs.Renderer objects cannot render the hosting display object.

Returns:: {boolean}

{boolean} isVisible()

Returns whether this state represents a visible state.

Returns:: {boolean}

resetBox()

Resets the bounding box.

updateBox(box)

Transforms a bounding box in the local coordinate system of the owner object to a box in the global coordinate system, which is used by the createjs.Renderer interface.

Parameters:
{createjs.BoundingBox} box
