Package com.twelvemonkeys.imageio.color

Class ColorSpaces

java.lang.Object

com.twelvemonkeys.imageio.color.ColorSpaces

public final class ColorSpaces
extends java.lang.Object

A helper class for working with ICC color profiles and color spaces.

Standard ICC color profiles are read from system-specific locations for known operating systems.

Color profiles may be configured by placing a property-file com/twelvemonkeys/imageio/color/icc_profiles.properties on the classpath, specifying the full path to the profiles. ICC color profiles are probably already present on your system, or can be downloaded from ICC, Adobe or other places. *

Example property file:

 # icc_profiles.properties
 ADOBE_RGB_1998=/path/to/Adobe RGB 1998.icc
 GENERIC_CMYK=/path/to/Generic CMYK.icc

Method Detail

createColorSpace

public static java.awt.color.ICC_ColorSpace createColorSpace(java.awt.color.ICC_Profile profile)

Creates an ICC color space from the given ICC color profile.

For standard Java color spaces, the built-in instance is returned. Otherwise, color spaces are looked up from cache and created on demand.

Parameters:

profile - the ICC color profile. May not be null.

Returns:

an ICC color space

Throws:

java.lang.IllegalArgumentException - if profile is null.

java.awt.color.CMMException - if profile is invalid.

isCS_sRGB

@Deprecated
public static boolean isCS_sRGB(java.awt.color.ICC_Profile profile)

Deprecated.

Use ColorProfiles.isCS_sRGB(ICC_Profile) instead.

isCS_GRAY

@Deprecated
public static boolean isCS_GRAY(java.awt.color.ICC_Profile profile)

Deprecated.

Use ColorProfiles.isCS_GRAY(ICC_Profile) instead.

validateProfile

@Deprecated
public static java.awt.color.ICC_Profile validateProfile(java.awt.color.ICC_Profile profile)

Deprecated.

Use ColorProfiles.validateProfile(ICC_Profile) instead.

getColorSpace

public static java.awt.color.ColorSpace getColorSpace(int colorSpace)

Returns the color space specified by the given color space constant.

For standard Java color spaces, the built-in instance is returned. Otherwise, color spaces are looked up from cache and created on demand.

Parameters:

colorSpace - the color space constant.

Returns:

the ColorSpace specified by the color space constant.

Throws:

java.lang.IllegalArgumentException - if colorSpace is not one of the defined color spaces (CS_*).
