By using the methods described in this book, developers will be able to fully exploit the state-of-the-art graphics capabilities of Mac OS X in their applications, whether for Cocoa or Carbon development. This book also serves as an introduction to 2D graphics concepts, including how images are drawn and how color is rendered. It includes guidance for working with PDF documents, drawing bitmap graphics, using Quartz built-in color management, and drawing text. Programming with Quartz is a rich resource for new and experienced Mac OS X developers, Cocoa and Carbon programmers, UNIX developers who are migrating to Mac OS X, and anyone interested in powerful 2D graphics systems.
- This is the definitive guide to the revolutionary graphics system of Mac OS X that uses the Portable Document Format (PDF) as the basis of its imaging model
- It contains the latest on programming with Quartz for Mac OS X version 10.4
- Carefully crafted and extensive code examples show how to accomplish most of the drawing tasks possible with Quartz
Cocoa and Carbon programmers who want to understand and fully exploit the power of the graphics system in Mac OS X and those who are looking to add new drawing capabilities, add support for PDF documents, or improve the quality of the graphics in their applications.
UNIX developers interested in the graphics capabilities of Mac OS X.
Web developers who want to create dynamic content using Quartz.

David Gelphman
David Gelphman is a senior software engineer on Apple's Graphics and Imaging team. He has over 20 years of experience working with the PostScript and PDF imaging model that is at the heart of Quartz graphics. His computer career began with scientific computing while he was earning his PhD in experimental particle physics at Stanford. Apple's introduction of the Macintosh in 1984 caused him to make a sharp turn into the world of user-friendly computing and he hasn't looked back.While working at Adobe Systems, David co-designed Apple's LaserWriter 8 printer driver and was team lead of the development project. At Adobe he also worked closely with third party developers, taught PostScript programming, wrote a number of technical notes, and contributed to the evolution of the PostScript language. After leaving Adobe he continued to combine software engineering work with documentation for software developers, authoring an article for Apple's develop technical journal in addition to a number of Apple technical notes. Today David writes system software for Mac OS X but continues to be involved with third party documentation and enjoys writing sample code for developers outside of Apple.
