Signature (4 bytes): A 32-bit unsigned integer that specifies the signature of color space objects. This MUST be set to the value 0x50534F43, which is the ASCII encoding of the string "PSOC".
Version (4 bytes): A 32-bit unsigned integer that defines a version number; it MUST be 0x00000400.
Size (4 bytes): A 32-bit unsigned integer that defines the size of this object, in bytes.
ColorSpaceType (4 bytes): A 32-bit signed integer that specifies the color space type. It MUST be defined in the LogicalColorSpace Enumeration (section 2.1.1.14). If this value is LCS_sRGB or LCS_WINDOWS_COLOR_SPACE, the sRGB color space MUST be used.
Intent (4 bytes): A 32-bit signed integer that defines the gamut mapping intent. It MUST be defined in the GamutMappingIntent Enumeration (section 2.1.1.11).
Endpoints (36 bytes): A CIEXYZTriple Object (section 2.2.2.7) that defines the CIE chromaticity x, y, and z coordinates of the three colors that correspond to the RGB endpoints for the logical color space associated with the bitmap. If the ColorSpaceType field does not specify LCS_CALIBRATED_RGB, this field MUST be ignored.
GammaRed (4 bytes): A 32-bit fixed point value that defines the toned response curve for red. If the ColorSpaceType field does not specify LCS_CALIBRATED_RGB, this field MUST be ignored.
GammaGreen (4 bytes): A 32-bit fixed point value that defines the toned response curve for green. If the ColorSpaceType field does not specify LCS_CALIBRATED_RGB, this field MUST be ignored.
GammaBlue (4 bytes): A 32-bit fixed point value that defines the toned response curve for blue. If the ColorSpaceType field does not specify LCS_CALIBRATED_RGB, this field MUST be ignored.
Filename (520 bytes): An optional, null-terminated Unicode UTF16-LE character string, which specifies the name of a file that contains a color profile. If a file name is specified, and the ColorSpaceType field is set to LCS_CALIBRATED_RGB, the other fields of this structure SHOULD be ignored.
See the LogColorSpace Object (section 2.2.2.11) for additional details concerning the interpretation of field values of this object.
