Color management examples

Modules
	ICM2 CMM example
	This example provides a core color management example module that acts as an interface to Microsoft's Image Color Management (ICM2) library.
	Common code for all CMM examples
	The CMM examples share functions to call the sw_memory_api callback API provided by the RIP for allocation and deallocation.
	Custom color space CMM example
	This example provides a core color management module that implements a collection of custom color spaces that may be used by the setinterceptcolorspace and setreproduction color operators.
	LittleCMS CMM example
	This example provides a core color management example module that acts as an interface to the open source LittleCMS color management library.
	Pure color preservation with ICC transforms
	This example module handles colors conversions that normally require an ICC CMM.

Detailed Description

Beyond the built-in CMM, the Core RIP provides two APIs that extend the color management options:

• Color management module interface - custom color space (CCS-CMM)
• Color management module interface - ICC (ICC-CMM)

Modules built using these APIs can be linked directly into an HHR RIP.

A CCS-CMM module augments the RIP with custom color spaces implemented in C callout functions. These may be used in the setinterceptcolorspace and setreproduction color operators. To configure the RIP to use a CCS-CMM module, use this fragment in the configuration PostScript:

(CMMname) setcustomcolorspacecmm

An ICC-CMM module augments the RIP with an alternate ICC CMM that replaces the RIPs built-in ICC CMM. To configure the RIP with an ICC-CMM module, use this fragment in the configuration PostScript:

(CMMname) setalternatecmm

The SDK includes these examples of Core Color Management modules:

• A custom color space example, which implements a variety of custom color spaces.
• An interface to LittleCMS, the open source ICC library.
• An interface to Microsoft™ Image Color Management (ICMv2) ICC library.
• A module that processes pure colors, but passes other colors back to the RIP's built-in CMM.

  @note The memory allocation and deallocation funtions provided by the CMM
  API should be used by alternate CMMs whenever possible, rather than the
  functions supplied by the operating system. Failure to do so may result
  in difficulties when configuring the RIP for optimal memory performance,
  especially in memory constrained environments.
