Description
Written by members of the development team at Apple, Programming with Quartz is the first book to describe the sophisticated graphics
system of Mac OS X. 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.
Audience
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.
