InterColor Profile Format Specification Version 3.0 June 10, 1994 6.21 XYZType The XYZType contains an array of three encoded values for the XYZ tristimulus values. The number of sets of values is determined from the size of the tag. The byte stream is given below. Tristimulus values must be non-negative, the signed encoding allows for implementation optimizations by minimizing the number of fixed formats. byte(s) content Encoded As... 0-3 ‘XYZ ‘ (0x58595A20) type descriptor 4-7 reserved, must be set to 0 8-n an array of XYZ numbers XYZNumber 50
InterColor Profile Format Specification Version 3.0 June 10, 1994 7 Basic Numeric Types 7.1 dateTimeNumber This dateTimeNumber is a 12 byte value representation of the time and date. The actual values are encoded as 16 bit unsigned integers. byte(s) content 0-1 number of the year ( actual year, i.e. 1994 ) 2-3 number of the month ( 1-12 ) 4-5 number of the day of the month ( 1-31 ) 6-7 number of hours ( 0-23 ) 8-9 number of minutes ( 0-59 ) 10-11 number of seconds ( 0-59 ) 7.2 s15Fixed16Number This type represents a fixed signed 4 byte/32 bit quantity which has 16 fractional bits. The encoding is such that : s15.16 Tristimulus Value Encoded Value -32768.9999 0xffffffff 0 0x00000000 1.0 0x00010000 32767.9999 0x7fffffff 7.3 u16Fixed16Number This type represents a fixed unsigned 4 byte/32 bit quantity which has 16 fractional bits. The encoding is such that : u16.16 Tristimulus Value Encoded Value 0 0x00000000 1.0 0x00010000 65535.9999 0xffffffff 7.4 uInt16Number This type represents a generic unsigned 2 byte/16 bit quantity. 51
