Class HSLFShape

java.lang.Object
  org.apache.poi.hslf.usermodel.HSLFShape

All Implemented Interfaces:

Shape<HSLFShape,HSLFTextParagraph>

Direct Known Subclasses:

HSLFBackground, HSLFGroupShape, HSLFSimpleShape

public abstract class HSLFShape
extends java.lang.Object
implements Shape<HSLFShape,HSLFTextParagraph>

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).
