Parameters
A map of options to pass to the method.

- the context the hit test is performed in
- location - Point
- the coordinates in world coordinate system
Returns
- ↪boolean
- whether something has been hit
Implements
Returns true if the corresponding item is considered to intersect the given rectangular box.
Remarks
This method may return false if the item cannot be selected using a selection marquee or optionally if the item is only partially contained within the box.
Implementations should respect the hitTestRadius if marquee selections should behave differently on different zoom levels.
Parameters

- rectangle - Rect
- the box describing the marquee's bounds
Returns
- ↪boolean
trueif the item is considered to be captured by the marquee
Implements
Returns true if the corresponding item is considered to intersect the given path.
Remarks
This method may return false if the item cannot be selected using a lasso selection or optionally if the item is only partially contained within the path.
Implementations should respect the hitTestRadius if lasso selections should behave differently on different zoom levels.
Parameters
A map of options to pass to the method.
- context - IInputModeContext
- the current input mode context
- lassoPath - GeneralPath
- the path describing the lasso selection bounds
Returns
- ↪boolean
trueif the item is considered to be captured by the lasso
Implements
Checks whether the given coordinate is deemed to lie within the shape's geometric bounds.
Parameters
A map of options to pass to the method.
- location - Point
- The point to test.
Returns
- ↪boolean
- True if the point lies within the shape.
Implements

Remarks
true.Parameters
A map of options to pass to the method.
- context - ICanvasContext
- The context to determine the visibility for.
- rectangle - Rect
- The visible region clip.
Returns
- ↪boolean
falseif and only if it is safe not to paint the element because it would not affect the given clipping region.
Implements
Implements the ILookup interface.
Remarks
this as a result of a successful lookup. This implementation will check if Type.IsInstanceOfType(this) and will call configure on success and return this.Type Parameters
- T: any
Parameters

- type - Class<T>
- The type to query for.
Returns
- ↪T
- An implementation or
null.

Implements
This method updates or replaces a previously created Visual for inclusion in the IRenderContext.
Remarks
The CanvasComponent uses this method to give implementations a chance to update an existing Visual that has previously been created by the same instance during a call to createVisual. Implementation may update the oldVisual and return that same reference, or create a new visual and return the new instance or null.
I most cases oldVisual is a visual instance that has been returned by the createVisual method of this instance. This is, however, not guaranteed. Implementations have to be aware of this.
Parameters
A map of options to pass to the method.
- context - IRenderContext
- The context that describes where the visual will be used in.
- oldVisual - Visual
- The visual instance to be updated.
Returns
- ↪Visual
oldVisual, if this instance modified the visual, or a new visual that should replace the existing one in the canvas object visual tree.
