Interface ImageAnnotation

All Superinterfaces:

Annotation, ShapeAnnotation

public interface ImageAnnotation
extends ShapeAnnotation

This annotation positions an image on on the screen. In the current implementation, the image is always rectangular, so the {@link ShapeAnnotation#getSupportedShapes method will always return a list with a single value: "Rectangle". In the future, this might be expanded to support clipping to a shape.

Cytoscape Backwards Compatibility (API Interface): We expect that this interface will be used but not implemented by developers using this interface. As such, we reserve the right to add methods to the interface as part of minor version upgrades. We will not remove methods for any changes other than major version upgrades.
