ICC_Profile

public class ICC_Profile extends Object implements Serializable
A representation of color profile data for device independent and device dependent color spaces based on the International Color Consortium Specification ICC.1:2001-12, File Format for Color Profiles, (see http://www.color.org).

An ICC_ColorSpace object can be constructed from an appropriate ICC_Profile. Typically, an ICC_ColorSpace would be associated with an ICC Profile which is either an input, display, or output profile (see the ICC specification). There are also device link, abstract, color space conversion, and named color profiles. These are less useful for tagging a color or image, but are useful for other purposes (in particular device link profiles can provide improved performance for converting from one device's color space to another's).

ICC Profiles represent transformations from the color space of the profile (e.g. a monitor) to a Profile Connection Space (PCS). Profiles of interest for tagging images or colors have a PCS which is one of the two specific device independent spaces (one CIEXYZ space and one CIELab space) defined in the ICC Profile Format Specification. Most profiles of interest either have invertible transformations or explicitly specify transformations going both directions.

public intgetColorSpaceType()
Returns the color space type. Returns one of the color space type constants defined by the ColorSpace class. This is the "input" color space of the profile. The type defines the number of components of the color space and the interpretation, e.g. TYPE_RGB identifies a color space with three components - red, green, and blue. It does not define the particular color characteristics of the space, e.g. the chromaticities of the primaries.

return
One of the color space type constants defined in the ColorSpace class.

Returns a particular tagged data element from the profile as a byte array. Elements are identified by signatures as defined in the ICC specification. The signature icSigHead can be used to get the header. This method is useful for advanced applets or applications which need to access profile data directly.

param

static java.awt.color.ICC_ProfilegetDeferredInstance(sun.awt.color.ProfileDeferralInfo pdi)
Constructs an ICC_Profile for which the actual loading of the profile data from a file and the initialization of the CMM should be deferred as long as possible. Deferral is only used for standard profiles. If deferring is disabled, then getStandardProfile() ensures that all of the appropriate access privileges are granted when loading this profile. If deferring is enabled, then the deferred activation code will take care of access privileges.

Returns a gamma value representing a tone reproduction curve (TRC). If the profile represents the TRC as a table rather than a single gamma value, then an exception is thrown. In this case the actual table can be obtained via getTRC(). theTagSignature should be one of icSigGrayTRCTag, icSigRedTRCTag, icSigGreenTRCTag, or icSigBlueTRCTag.

Constructs an ICC_Profile corresponding to the data in a file. fileName may be an absolute or a relative file specification. Relative file names are looked for in several places: first, relative to any directories specified by the java.iccprofile.path property; second, relative to any directories specified by the java.class.path property; finally, in a directory used to store profiles always available, such as the profile for sRGB. Built-in profiles use .pf as the file name extension for profiles, e.g. sRGB.pf. This method throws an IOException if the specified file cannot be opened or if an I/O error occurs while reading the file. It throws an IllegalArgumentException if the file does not contain valid ICC Profile data.

Returns the TRC as an array of shorts.

Otherwise the short array returned here represents a lookup table where the input Gray value is conceptually in the range [0.0, 1.0]. Value 0.0 maps to array index 0 and value 1.0 maps to array index length-1. Interpolation may be used to generate output values for input values which do not map exactly to an index in the array. Output values also map linearly to the range [0.0, 1.0]. Value 0.0 is represented by an array value of 0x0000 and value 1.0 by 0xFFFF, i.e. the values are really unsigned short values, although they are returned in a short array. theTagSignature should be one of icSigGrayTRCTag, icSigRedTRCTag, icSigGreenTRCTag, or icSigBlueTRCTag.

private voidreadObject(java.io.ObjectInputStream s)
Reads default serializable fields from the stream. Reads from the stream a string and an array of bytes as additional data.

param
s stream used for deserialization.
throws
IOException thrown by ObjectInputStream.
throws
ClassNotFoundException thrown by ObjectInputStream.
serialData
The String is the name of one of CS_* constants defined in the {@link ColorSpace} class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. It will usually be null for the predefined profiles.

If the string is recognized as a constant name for predefined color space the object will be resolved into profile obtained with getInstance(int cspace) and the profile data are ignored. Otherwise the object will be resolved into profile obtained with getInstance(byte[] data).

serialData
The String is the name of one of CS_* constants defined in the {@link ColorSpace} class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. For predefined color spaces null is written instead of the profile data. If in the future versions of Java API new predefined color spaces will be added, future versions of this class may choose to write for new predefined color spaces not only the color space name, but the profile data as well so that older versions could still deserialize the object.
