getDescendants
▸ getDescendants(reversed?

[]
Returns the descendants of this node.
A descendant is node that has this node as an ancestor. Consider for example the following tree of nodes:
- NodeA
- NodeB
- NodeD
- NodeE
- NodeC
- NodeB
If we ask for the descendants of NodeA we'll get back: [NodeB, NodeD, NodeE, NodeC]
If reversed is set to true then this method will return the reversed descendants. For the example above, that would be: [NodeC, NodeE, NodeD, NodeB, NodeA]. Note that the first item of the reversed descendants has the highest z-index.
Parameters
Name | Type | Default value |
---|---|---|
reversed | boolean | false |
Returns

getExtras
▸ getExtras(): any
Returns any extra data that this object needs to save during serialization.
In some cases an object might need to save some extra data without necessarily this extra data being part of its state (e.g. the AssetsLibrary of a Scene). In these cases subclasses can re-implement this method and return the data required.
The default implementation returns undefined
meaning that no extra data
needs to be saved during serialization.

getSceneBoundingRect
▸ getSceneBoundingRect(): Rectangle
Returns the bounding rectangle of this JointNode in scene coordinates.

Returns the Node's position in Scene coordinates.
Returns
IPoint
Inherited from
getSceneTransform
▸ getSceneTransform(): Matrix
Returns a copy of this node's scene transformation matrix. Use this matrix to map coordinates from this node's local coordinate system to the scene's coordinate system. To map coordinates from the scene, you must first invert the returned matrix.
Unlike getLocalTransform(), which returns only the local transformation, this function includes the node's (and any parents') position, and all the transfomation properties.
Returns
Matrix
Inherited from
GraphicsNode.getSceneTransform
getShape
▸ getShape(): Polygon
Returns the shape of this Node in local coordinates.
Note that the returned shape might be empty.
The shape of a Node is used for many things, including boolean operations and selection.
The default implementation calls getBoundingRect() to return a simple rectangular shape, but subclasses can reimplement this function to return a more accurate shape for non-rectangular items.
Returns
Polygon

The object's state is an object containing key/value pairs corresponding to this object's properties. For example:
{
id: "Ssba4ch5ruok",
name: "Circle",
radius: 2,
// ...
}
To avoid including properties that are currently in their default value you can set minified = true when calling getState.
Note that read-only properties are not part of the object's state (with the exception of the id)
Parameters
Name | Type | Default value | Description |
---|---|---|---|
minified | boolean | false | Whether to return a minified state or not |
