Overview

This document describes the constants defined in the Application Kit framework that are not defined in, or are not described in, a document for an individual class.

See Application Kit Data Types Reference for descriptions of other constants defined in enumerations.

Constants

There are three types of constant in this document: global variables, errors, and exceptions.

Global Variables

Color Space Names

Color-space names designate predefined color spaces. 

NSString *NSCalibratedWhiteColorSpace;
NSString *NSCalibratedBlackColorSpace;
NSString *NSCalibratedRGBColorSpace;
NSString *NSDeviceWhiteColorSpace;
NSString *NSDeviceBlackColorSpace;
NSString *NSDeviceRGBColorSpace;
NSString *NSDeviceCMYKColorSpace;
NSString *NSNamedColorSpace;
NSString *NSPatternColorSpace;
NSString *NSCustomColorSpace;
Constants
NSCalibratedWhiteColorSpace

Calibrated color space with white and alpha components (pure white is 1.0)

Available in OS X v10.0 and later.

Declared in NSGraphics.h.

NSCalibratedBlackColorSpace

Calibrated color space with black and alpha components (pure black is 1.0)

Available in OS X v10.0 and later.

Deprecated in OS X v10.6.

Declared in NSGraphics.h.

NSCalibratedRGBColorSpace

Calibrated color space with red, green, blue, and alpha components.

You can also create a color with HSB (hue, saturation, brightness) and alpha components and can extract these components.

Available in OS X v10.0 and later.

Declared in NSGraphics.h.

NSDeviceWhiteColorSpace

Device-dependent color space with white and alpha components (pure white is 1.0)

Available in OS X v10.0 and later.

Declared in NSGraphics.h.

NSDeviceBlackColorSpace

Device-dependent color space with black and alpha components (pure black is 1.0)

Available in OS X v10.0 and later.

Deprecated in OS X v10.6.

Declared in NSGraphics.h.

NSDeviceRGBColorSpace

Device-dependent color space with red, green, blue, and alpha components.

You can also create a color with HSB (hue, saturation, brightness) and alpha components and can extract these components.

Available in OS X v10.0 and later.

Declared in NSGraphics.h.

NSDeviceCMYKColorSpace

Device-dependent color space with cyan, magenta, yellow, black, and alpha components

Available in OS X v10.0 and later.

Declared in NSGraphics.h.

NSNamedColorSpace

Catalog name and color name components

The components of this color space are indexes into lists or catalogs of prepared colors. The catalogs of named colors come with lookup tables that are able to generate the correct color on a given device.

Available in OS X v10.0 and later.

Declared in NSGraphics.h.

NSPatternColorSpace

Pattern image (tiled)

Identifies a pattern color space, which is simply an image that is repeated over and over again in a tiled pattern.

Available in OS X v10.0 and later.

Declared in NSGraphics.h.

NSCustomColorSpace

Custom NSColorSpace object and floating-point components describing a color in that space

A custom color-space object represents a color space that is not necessarily predefined by the Application Kit. See “Working With Color Spaces” for information on creating custom color-space objects.

Available in OS X v10.0 and later.

Declared in NSGraphics.h.

Discussion

You can use a color-space name in certain methods of NSColor that create or convert color objects. The name identifies the color space to be used for the operation.
