public abstract class Shape
extends java.lang.Object

Represents a Shape which is the elemental object that composes a drawing. This class is a wrapper around EscherSpContainer which holds all information about a shape in PowerPoint document.

When you add a shape, you usually specify the dimensions of the shape and the position of the upper�left corner of the bounding box for the shape relative to the upper�left corner of the page, worksheet, or slide. Distances in the drawing layer are measured in points (72 points = 1 inch).
