Preface

This document introduces the Eclipse ImageN API and how to program in it. This document is intended for serious programmers who want to use ImageN for real projects. To best understand this document and the examples, you need a solid background in the Java programming language and some experience with imaging. In addition, you will need a working knowledge of other Java APIs, depending on your intended application:

  • Java ImageIO for image encoding and decoding

  • Java 2D for simple graphics, text, and fundamental image manipulation

This library is an Apache License v 2.0 release of the former Java Advanced Imaging API codebase. Method compatibility has been maintained using new packages and library name.

Disclaimer

This version of is based on release 0.4-SNAPSHOT of the Eclipse ImageN API:

If any discrepancies between this guide and the javadocs are noted, always consider the javadocs to be the most accurate, since they are generated directly from the source files and are always the most up to date.

About This Book

Chapter 1, "Introduction to Eclipse ImageN", gives an overview of the Eclipse ImageN API, how it evolved from the original Java Advanced Windowing Toolkit (AWT), previous Java Advanced Imaging API (JAI), some of its features, and introduces the imaging operations.

Chapter 2, "Java AWT Imaging",” reviews the imaging portions of the Java AWT and examines the imaging features of the Java 2D API.

Chapter 3, "Programming Environment", describes how to get started programming with the Eclipse ImageN.

Chapter 4, "Image Acquisition and Display", describes the image data types and the API constructors and methods for image acquisition and display.

Chapter 5, "Color Space", describes the color space, transparency, and the color conversion operators.

Chapter 6, "Image Manipulation", describes the basics of manipulating images to prepare them for processing and display.

Chapter 7, "Image Enhancement", describes the basics of improving the visual appearance of images through enhancement techniques.

Chapter 8, "Geometric Image Manipulation", describes the basics of geometric image manipulation functions.

Chapter 9, "Image Analysis", describes the image analysis operators.

Chapter 10, "Graphics Rendering", describes the presentation of shapes and text.

Chapter 11, "Image Properties", describes the tools that allow a programmer to add a simple database of arbitrary data that can be attached to images.

Chapter 12, "Client-Server Imaging", describes client-server imaging system.

Chapter 13, "Writing Image Files", describes Eclipse ImageN's codec system for encoding image data files.

Chapter 14, "Extending the API", describes Eclipse ImageN API is extended.

Appendix A, "Program Examples", contains fully-operational Eclipse ImageN program examples.

Appendix B, "API Summary", summarizes the imaging interfaces, and classes, including the java.awt, java.awt.Image, and org.eclipse.imagen classes.

The Glossary contains descriptions of significant terms that appear in this book.

For more information on digital imaging, we suggest you refer to the following books:

  • Fundamentals of Digital Image Processing, by Anil K. Jain

  • Digital Image Processing: Principles and Applications, by Gregory A. Baxes

  • Digital Image Processing, by Kenneth R. Castleman

  • Digital Image Processing, 2nd. ed., by William K. Pratt

Additional Information

Since Eclipse ImageN continues to evolve and periodically add new operators, it is always a good idea to occasionally check the project page for the latest information.

  • https://projects.eclipse.org/projects/technology.imagen

The web site contains links to the latest version of ImageN, email list to take part in the community, and tutorial and demos including examples of the use of many ImageN operators.

Style Conventions

The following style conventions are used in this document:

  • Monspace is used to represent computer code and the names of files and directories.

  • Bold is used for API declarations.

  • Italic type is used for emphasis and for equations.

Throughout the book, we introduce many API calls with the following format:

API: org.eclipse.imagen.TiledImage

When introducing an API call for the first time, we add a short list of the methods, tagged with the API heading.
