PROFILEHEADER

  • Article

The PROFILEHEADER structure contains information that describes the contents of a device profile file. This header occurs at the beginning of a device profile file.

typedef struct tagPROFILEHEADER {
  DWORD   phSize;
  DWORD   phCMMType;
  DWORD   phVersion;
  DWORD   phClass;
  DWORD   phDataColorSpace;
  DWORD   phConnectionSpace;
  DWORD   phDateTime[3];
  DWORD   phSignature;
  DWORD   phPlatform;
  DWORD   phProfileFlags;
  DWORD   phManufacturer;
  DWORD   phModel;
  DWORD   phAttributes[2];
  DWORD   phRenderingIntent;

  DWORD   phCreator;
  BYTE    phReserved[44];
} PROFILEHEADER;

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_EMBEDDEDPROFILE The profile is embedded in a bitmap file.
    FLAG_DEPENDENTONDATA The 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.
