Type Details
- yfiles module
- styles-other
- yfiles-umd modules
- All view modules
- Legacy UMD name
- yfiles.styles.ImageNodeStyleRenderer
Properties
Gets the layout of the node this renderer is currently configured for.
Remarks
Node.Layout.Gets or sets the currently configured node.
Gets or sets the currently configured style.
Methods
Prepares this instance for subsequent calls after the style and node have been initialized.
Remarks
Upon invocation the style and node properties have been populated by the getVisualCreator, getBoundsProvider, getHitTestable, or getMarqueeTestable methods.
This is an empty implementation. Subclasses might have to override this method.
This method is called by the framework to create a Visual that will be included into the IRenderContext.
Remarks
Parameters
A map of options to pass to the method.
- context - IRenderContext
- The context that describes where the visual will be used.
Returns
- ↪Visual
- The visual to include in the canvas object visual tree. This may be
null.

Implements
Returns the aspect ratio with which the image is rendered.
Remarks
The default implementation returns the aspect ratio of the associated style instance.
Values ≤ 0 are ignored, i.e. the image is stretched to the node's bounds.
Returns
- ↪number
- Returns the aspect ratio with which the image is rendered.
Gets the rendering bounds for this style renderer.
Remarks
Parameters
A map of options to pass to the method.
- context - ICanvasContext
- the context to calculate the bounds for
Returns
- ↪Rect
- the rendering bounds for this style renderer.
Implements
Configures the style and node parameters, calls configure and returns this.
Parameters
A map of options to pass to the method.

- The node to retrieve the bounds provider for. The value will be stored in the node property.
- style - INodeStyle

Implements
Tries to use normalizedOutline to perform the hit test analysis, otherwise reverts to default (rectangular) behavior.
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

Parameters
A map of options to pass to the method.
- context - IInputModeContext
- the current input mode context
- rectangle - Rect
- the box describing the marquee's bounds
Returns
- ↪boolean
trueif the item is considered to be captured by the marquee
Implements

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

Implements
Tries to use the normalizedOutline to perform the contains test, otherwise reverts to default (rectangular) behavior.
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
Determines visibility by checking for an intersection with the layout.
Parameters
A map of options to pass to the method.
- context - ICanvasContext
- The context.
- rectangle - Rect
- The current clip
Returns
- ↪boolean
- Whether the layout is visible in the clip.
Implements
Implements the ILookup interface.
Remarks
GetContext. Subclass implementations should make sure to configure this instance before they return 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
A map of options to pass to the method.
- 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.

Constants
A string that will be used to find the fallback image url that will be used to render the node, if the style does not explicitly specify a fallback image.
