The invention discloses a system method for providing new functionality to an operating system while maintaining backward compatibility with existing applications. The invention can provide new functionality while maintaining backward compatibility without a requirement to change any syntax of an API and without having to create new APIs for all functions. The invention can be configured to pass monolithic data as well as modular data through either legacy APIs or newly created APIs.

Providing new functionality while maintaining backward compatibility

Methods and apparatuses for supporting a color management system that processes an image in accordance to a hierarchically-structured policy are provided. The policy may be modeled with a schema in which the policy is organized with a plurality of policy levels. Policy settings at a lower policy level may override policy settings at a higher policy level, which may be inhibited with a lockout mechanism. A user interface supports the capability of a user configuring policy settings through a series of dialog boxes. The dialog boxes are hierarchically organized in accordance with configuration levels, where the configuration levels are associated with the policy levels. The dialog boxes provide a consolidated approach for configuring a color management system by a user. An interface is supported, enabling a component to send inputs to a color management system in order to configure the policy.

System for customer and automatic color management using policy controls

A color engine supports extensibility by allowing plug-ins. The color engine transforms an image file associated with a source device for consumption by a destination device. Within the color engine, a device model operates over a device model profile to generate a gamut boundary shell, which describes the range of colors a device is capable of producing. A color appearance model operates over a color appearance model profile to compensate for external viewing conditions. A gamut map model accepts as input gamut boundary shells describing the source device and the destination device, and operates over a gamut map model profile to generate a transform, which is used to transform the image file for consumption by the destination device. The device model profiles and gamut map model profiles may be extended using XML plug-ins, and the device models and gamut map models may be extended using DLL plug-ins.

Extensible system for color management

A system and method for selectively setting gamut map model defaults in a color management system is disclosed for transforming colors from a first color space to a second color space. The method includes the steps of comprises determining the profile associated with the second color space from one of an ICC profile, a device model profile and a system default profile; associating a color appearance profile and a gamut mapping profile based on the profile; and selecting at least one of the color appearance and gamut mapping profiles based on the profile associated with the second color space.

Gamut mapping and rendering intent management system

Techniques relating to gamuts and gamut mapping are described. In one instance, a process identifies a gamut attribute and generates a gamut having the attribute.

Gamuts and gamut mapping

The disclosed method diminishes the resolution or the perceived resolution of images and compares the images to evaluate the color image quality of images. The method determines how far away images have to be or how much the resolution needs to be reduced for the images to be perceived as the same. A smaller viewing distance or a lower reduction in resolution corresponds to a closer similarity between the images. A relatively longer viewing distance or a greater reduction in resolution where the visual difference becomes unperceivable is indicative of a large difference between the images.
