Class Bounds

java.lang.Object
org.openscience.cdk.renderer.elements.Bounds
All Implemented Interfaces:
IRenderingElement
public final class Bounds extends Object implements IRenderingElement
Defines a bounding box element which the renderer can use to determine the true drawing limits. Using only atom coordinates adjuncts (e.g. hydrogen labels) may be truncated. If a generator provide a bounding box element, then the min/max bounds of all bounding boxes are utilised.
