Preface

The KCMS CMM Developer's Guide describes how to create a Kodak Color Management System (KCMS(TM)) color management module (CMM). It provides information on how to use the KCMS foundation library, which is a graphics porting interface (GPI) implemented in C++. These C++ interfaces link the device-independent layer of the KCMS library with the CMM and enable the flow of data from the application to the CMM.

Use this manual with the KCMS CMM Reference Manual, which provides detailed information on all C++ classes in the KCMS foundation library.

Who Should Use This Guide

Use this guide if you are a C++ programmer interested in:

  • Writing your own color management module (CMM)

  • Creating your own profile format

  • Adding attributes or tags to the ICC profile format

  • Overriding various class methods

Before You Read This Guide

Check all of the following for any KCMS-specific or system release-specific information that you might need:

  • You should be familiar with the Kodak Color Management System (KCMS) API, which is part of the Software Developer's Kit (SDK). See the following manual:

  • You should also have an understanding of C++ and Solaris(TM) dynamic loading technology. Solaris dynamic loading is discussed in the Linker and Libraries Guideand in the following manual pages:

    • ld()(1)

    • dlopen(3)

    • dlclose()(3)

    • dlerror()(3)

    • dlsym()(3)

  • For SPARC systems, consult the updates your hardware manufacturer may have provided.

How This Guide Is Organized

Chapter 1, Class Descriptions briefly describes each of the relevant classes in the KCMS CMM class hierarchy.

Chapter 2, CMM : A Runtime Derivative describes how to create a CMM that is a runtime derivative. It also discusses each of the KCMS classes from which you can derive or extend.

Chapter 3, KCMS Framework Operations provides examples of how some of the C++ methods interface with the KCMS framework API.

Chapter 4, KcsIO Derivative describes how to derive from the KcsIO base class.

Chapter 5, KcsProfile Derivative describes how to derive from the KcsProfile base class.

Chapter 6, KcsProfileFormat Derivative describes how to derive from the KcsProfileFormat base class.

Chapter 7, KcsXform Derivative describes how to derive from the KcsXform base class.

Chapter 8, KcsStatus Extension describes how to extend the KcsStatus base class.

Appendix A, Supported Devices describes how to name and install your own profile.

Equivalent Terms In This Guide

For historic reasons, this guide uses several equivalent Kodak and ICC terms. The terms evolved at different times. Development of the ICC specification introduced new ICC terms with meanings the same as (or similar to) already existing Kodak terms.

You should be familiar with the terms listed in the table below, as you will encounter them in the ICC specification and KCMS color management documentation, as well as in the KCMS header files and example programs. The terms are defined as they are introduced in this guide.

Table P-3 Equivalent ICC and Kodak Terms

Kodak Term 

ICC Term 

attribute 

tag 

device color profile (DCP) 

input, display, or output profile 

effects color profile (ECP) 

abstract profile 

complete color profile (CCP) 

device link profile 

profile format Id or magic number 

profile file signature 

reference color space (RCS) 

profile connection space (PCS) 

Note -

The text in this guide uses the term attribute instead of tag, (but code examples and header files may use tag for the historic reasons previously mentioned.
