MacOS X Developer Preview Release Notes Copyright © 2000 by Apple Computer, Inc. All Rights Reserved.
The Quartz API shipped with the Developer Preview 3 release of MacOS X is preliminary, incomplete, and subject to revision. It is highly recommended that you use the native drawing facilities of Cocoa or Carbon at present, and avoid using Quartz directly.
If you are interested in using the revised Quartz API, please join Apple Computer at the Worldwide Developers Conference, where the 1.0 version of Quartz will be presented.
Quartz is an API that allows developers to present 2-dimensional shapes, text and images in various graphics contexts. For Quartz, the graphics contexts include screen display, PDF generation and printer output.
While Quartz is the foundation of the window system and PDF support on MacOS X, the API is limited in scope, and supports only the 2-dimensional rendering in the contexts mentioned above. At present, Quartz does not provide a general API for creating or manipulating windows, nor does it provide arbitrary editing of PDF documents.
