Members
phSize
The size of the profile in bytes.phCMMType
The identification number of the CMM that is used in the profile. Identification numbers are registered with the ICC.phVersion
The version number of the profile. The version number is determined by the ICC. The current major version number is 02h. The current minor version number is 10h. The major and minor version numbers are in binary coded decimal (BCD). They must be stored in the following format.Byte Number Contents 0 Major version number in BCD. 1 Minor version number in the most significant nibble of this byte. Bug fix version number in the least significant nibble. 2 Reserved. Must be set to 0. 3 Reserved. Must be set to 0. phClass
Indicates the profile class. For a description of profile classes, see Using Device Profiles with WCS. A profile class may have any of the following values.Profile Class Signature Input Device Profile CLASS_SCANNER Display Device Profile CLASS_MONITOR Output Device Profile CLASS_PRINTER Device Link Profile CLASS_LINK Color Space Conversion Profile CLASS_COLORSPACE Abstract Profile CLASS_ABSTRACT Named Color Profile CLASS_NAMED Color Appearance Model Profile CLASS_CAMP Color Gamut Map Model Profile CLASS_GMMP phDataColorSpace
A signature value that indicates the color space in which the profile data is defined. The member can be any of value from the Color Space Constants.phConnectionSpace
A signature value that indicates the color space in which the profile connection space (PCS) is defined. The member can be any of the following values.Profile Class Signature XYZ SPACE_XYZ Lab SPACE_Lab When the phClass member is set to CLASS_LINK, the PCS is taken from the phDataColorSpace member.
phDateTime
The data and time that the profile was created.phSignature
Reserved for internal use.phPlatform
The primary platform for which the profile was created. The primary platform can be set to any of the following values.Platform Value Apple Computer, Inc. 'APPL' Microsoft Corp. 'MSFT' Silicon Graphics, Inc. 'SGI' Sun Microsystems, Inc. 'SUNW' Taligent 'TGNT' phProfileFlags
Bit flags containing hints that the CMM uses to interpret the profile data. The member can be set to the following values.Constant Meaning FLAG_EMBEDDEDPROFILEThe profile is embedded in a bitmap file.FLAG_DEPENDENTONDATAThe profile can't be used independently of the embedded color data. Used for profiles that are embedded in bitmap files.phManufacturer
The identification number of the device profile manufacturer. All manufacturer identification numbers are registered with the ICC.phModel
The device manufacturer's device model number. All model identification numbers are registered with the ICC.phAttributes
Attributes of profile. The profile attributes can be any of the following values.Constant Meaning ATTRIB_TRANSPARENCY Turns transparency on. If this flag is not used, the attribute is reflective by default. ATTRIB_MATTE Turns matte display on. If this flag is not used, the attribute is glossy by default. phRenderingIntent
The profile rendering intent. The member can be set to one of the following values:INTENT_PERCEPTUAL
INTENT_SATURATION
INTENT_RELATIVE_COLORIMETRIC
INTENT_ABSOLUTE_COLORIMETRIC
For more information, see Rendering Intents.
phIlluminant
Profile illuminant.phCreator
Signature of the software that created the profile. Signatures are registered with the ICC.phReserved
Reservedfuture.
