Preface

Introduction

The KCMS Calibrator Tool Loadable Interface Guide describes how to create a dynamically loadable device handler to be used in calibrating devices. Your colorimeter software interacts with the Kodak Color Management System (KCMS^(TM)) Calibrator Tool to gather the color measurements needed to correct ICC format profiles. The measurement data is then used by the KCMS framework to achieve the device independent display of color images. Currently calibration of color monitor devices only is supported.

This guide is part of the software development kit (SDK) portion of the KCMS software product.

Who Should Use This Book

This guide is intended to be used by programmers who are writing dynamically installable modules (for example, colorimeter device handlers) that provide KCMS Calibrator Tool with color measurement data. This guide assumes its readers are familiar with the KCMS color management software and the colorimeter hardware.

Before You Read This Book

Before reading this guide, you should

• Read the KCMS Application Developer's Guide. The KCMS Calibrator Tool Loadable Interface Guide assumes you understand the color concepts (such as characterization, profiles, and calibration) described in the Developer's Guide. The Developer's Guide also describes the KCMS API library and provides background information on the interface between Calibrator Tool, the KCMS library, and color profiles.
• See the on-line SUNWrdm packages for information on bugs and issues, engineering news, and patches. For Solaris^(TM) installation bugs and for late-breaking bugs, news, and patch information, see the Installation Instructions for Solaris 2.6 (Intel Platform Edition) and the Installation Instructions for Solaris 2.6 (SPARC Platform Edition).
• (SPARC^(TM) systems) Consult the updates your hardware manufacturer may have provided.

How This Book Is Organized

This guide is organized into the following chapters:

Chapter 1, "Overview," is an overview of color calibration. Read this chapter to understand the main software components involved in calibration. The chapter summarizes how Calibrator Tool (which is executed with the kcms_calibrate(1) command) interacts with the dynamically loadable module to obtain calibration data. (For details on kcms_calibrate(1), see the man page description.)

Chapter 2, "Calibrating A Monitor," describes calibration from the end-user perspective and the action of the underlying sample software.

Chapter 3, "OWconfig Database," details how you insert and delete OWconfig entries for dynamically loadable calibration modules.

Chapter 4, "Measuring Monitor Response," touches on the rationale Calibrator Tool uses to gather measurement data.

Chapter 5, "Data Structures," describes the structures Calibrator Tool uses for measurement data.

Chapter 6, "Functions," alphabetically presents and describes the interfaces a loadable module uses to interact with Calibrator Tool.

Glossary defines words and phrases used in this guide.

Naming Conventions

In this guide, KCMS refers to the Kodak Color Management System. The names of calibration functions and data structures consist of the prefix string 'KCMS' plus other significant words that suggest what the function or data structure does. To illustrate, KCMSCMonInit() is a function name consisting of four significant words:

• KCMS
• C
• Mon
• Init

Table P-4 describes each significant word.

Table P-4

Significant Word	Meaning
KCMS	Kodak Color Management System
C	Calibrator
Mon	Monitor device
Init	Initialization function
