Using the ColorSync Manager With ColorSync 1.0 Profiles

Despite differences between the version 2.x and ColorSync 1.0 profile formats, you can use most of the ColorSync Manager functions to gain access to ColorSync 1.0 profiles and their contents and to color match to and from the two disparate profile formats, if necessary. The ColorSync Manager makes this possible.

You can open a reference to a ColorSync 1.0 profile using the ColorSync Manager functions and special data structures that accommodate both profile styles. You can also match the colors of an image expressed in the color gamut of one device whose characteristics are described by a ColorSync 1.0 profile to the colors within the gamut of another device whose characteristics are described by a version 2.x profile.

IMPORTANT

If you are color matching between devices that both use ColorSync 1.0 profiles, you should use the ColorSync functions that work with 1.0 profiles for the process.

The next section describes
