The file containing the lookup table. It is passed to the Parameter
LUT but not validated.
DEVICE = DEVICE (Read)
Name of the graphics
device whose colour table is to be changed.
[Current graphics device
LUT = NDF
Name of the NDF containing the lookup table as its data array. The LUT must be
two-dimensional, the first dimension being 3, and the second being arbitrary.
Linear interpolation is used to compress or expand the colour table if the
second dimension is different from the number of unreserved colour indices.
Also the LUT’s values must lie in the range 0.0–1.0.
This is a
procedure that calls LUTABLE. Therefore, the parameters cannot be specified on the
command line. You will only be prompted for the parameters if the device is not
suitable or not available, and/or the lookup table file could not be accessed.
