Contains
A series of numeric values specifying the output values of the LUT. The corresponding input values are
implied by the inBitDepth (page 1334) of the containing element and the number of entries (uniform
distribution).
For a 3D LUT, each entry has three values specifying the separate R, G, and B output values. The entries
are in order from minimum to maximum with the index of the last column changing fastest and the
index of the first column changing slowest. For example, the order of entries for a 2×2×2 cube is:
BGREntry
0001
1002
0103
1104
0015
1016
0117
1118

Attributes
dim Four integers representing the dimensions of a 3D cube followed by followed by the number of
components per entry.
Only 3D LUTs with the same dimension in all three channels are supported, so the first three values must
be the same. The fourth value must be 3.
The dim attribute is required, and its value must match the number of entries actually present.
