Managing Color With ColorSync


CHAPTER 4

Developing ColorSync-Supportive Device Drivers

This section describes how you can use the ColorSync Manager to provide ColorSync-supportive device drivers for peripherals. It first describes how input, display, and output devices work with color profiles. It then discusses how devices interact with color management modules (CMMs). Next it describes what you must do to provide minimum ColorSync support, as well as how you can provide more extensive support. Finally, it uses a QuickDraw-based printer device driver to demonstrate some of the color-matching features a device driver can provide.

Read this section if your device driver for an input, display, or output device will support the ColorSync Manager and allow users to produce color-matched images.

Before you read this section, you should read Introduction to ColorSync and Introduction to Color and Color Management Systems . These sections provide an overview of ColorSync, explain color theory and color management systems, and define key terms.

Although the features described here are commonly provided by printer device drivers, the code samples in Developing ColorSync-Supportive Applications may also be of use in developing your device driver.

ColorSync Reference for Applications and Drivers describes constants, data structures, functions, and result codes for ColorSync-supportive applications and device drivers.

ColorSync Version Information 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 includes CPU and Mac OS system requirements.
