Package org.cytoscape.view.presentation.annotations

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 method will always return a list with a single value: "Rectangle". In the future, this might be expanded to support clipping to a shape.

Module: presentation-api

To use this in your app, include the following dependency in your POM:

<dependency>
    <groupId>org.cytoscape</groupId>
    <artifactId>presentation-api</artifactId>
</dependency>
