Inside Macintosh: What's New in Advanced Color Imaging on the Mac OS /
ColorSync 2.1


ColorSync 2.1 Overview

The ColorSync Manager provides your application or color peripheral device driver with device-independent color-matching and color-conversion services.

The revised advanced color imaging books provide information on the many new features available in version 2.1 of the ColorSync Manager, including

The section "ColorSync 2.1 Changes" describes these features in greater detail and provides hypertext links to new and changed material in the revised advanced color imaging books.

A Note on ColorSync Versions

This document and the advanced color imaging books use "ColorSync Manager" or "ColorSync" to refer to version 2.1. They use a specific version number, such as "ColorSync 1.0," only where necessary to identify features associated with a particular version. They most commonly use "2.x" to refer to the International Color Consortium (ICC) profile reference format version used by version 2.0 and later of the ColorSync Manager. However, where appropriate, they may use "2.x" to refer inclusively to ColorSync versions 2.0 and 2.1.

If you need documentation for version 2.0 of the ColorSync Manager, see "Obtaining the Original Advanced Color Imaging Books" in this document.

Backward Compatibility

Most existing code written to use version 2.0 of the ColorSync Manager should continue to work with version 2.1 without modification.

Although ColorSync 1.0 used a proprietary profile format, the ColorSync Manager provides backward compatibility for applications and device drivers written for ColorSync 1.0. Your application that uses the ColorSync Manager can match, convert, and gamut check colors using version 2.x profiles or, when necessary, a combination of version 2.x profiles and ColorSync 1.0 profiles. For a description of the backward compatibility support provided by the ColorSync Manager, see the appendix, "ColorSync Manager Backward Compatibility," in Advanced Color Imaging on the Mac OS.
