Managing Color With ColorSync


CHAPTER 8

Version and Compatibility Information

This section describes the Gestalt information, shared library version numbers, CMM version numbers, and ColorSync header files you use with different versions of the ColorSync Manager. It also describes CPU and system requirements.

This section also describes backward compatibility support for ColorSync 1.0 functions, profiles, and CMMs provided by the ColorSync Manager in versions 2.0 and later.

In addition, this section explains how to use the ColorSync Manager for color matching between a ColorSync 1.0 profile and a version 2.x profile.

Version 2.5 of the ColorSync Manager replaces all earlier versions of the product, including ColorSync 2.1, 2.0, and 1.0.

Note

There are no changes to the ColorSync Manager API between version 2.5 and version 2.5.1, so this document is up-to-date for ColorSync 2.5.1.

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 color check colors using version 2.x profiles or, when necessary, using a combination of version 2.x profiles and ColorSync 1.0 profiles.

IMPORTANT

Although ColorSync version 2.5 fully supports 1.0 format profiles, this support is not guaranteed to continue in future versions. Apple strongly recommends that developers using the 1.0 format move to the 2.x format.
