Download Dither Matrix
Specifies a single dither matrix for all three primaries, or three matrices
(one for each primary) which may have different sizes and contents.
? * m # W
[binary data]
# =
Number of bytes in the data field
Color Lookup Tables
Enables and specifies color lookup tables.
? * l # W
[binary data]
# =
Number of bytes in the data field
Gamma Correction
Specifies the gamma correction to be applied equally for each primary.
? * t # I
# =
Gamma number
Viewing Illuminant
Specifies the relative white point used in the determination of a viewing
illuminant condition.
? * i # W
[binary data]
# =
Number of bytes in the data field
