| iTool User's Guide: Adding Annotations |

## Introduction

The Standard IDL iTools supplied in the IDL distribution (iImage, iPlot, iSurface, iContour, iVolume, iMap, and iVector) each posses common annotation capabilities. This chapter describes this common annotation functionality and how it can be used.

Note This chapter describes Annotation functionality for only the Standard IDL iTools, those iTools supplied in the IDL distribution. Other iTools written by users and third-party developers share a common interface with the RSI iTools because the iTools framework is used to create all iTools. However, the specific functionality of such iTools may be different from the functionality of the iTools described here.
