Unfortunately, you cannot just pass a list of values to the
'gimp-curves-spline' PDB function; you must pass that list as an array
of 8-bit values.
You can create such an array with code similar to the following
(let* (
(my-curve (cons-array 6 'byte))
)
(aset! my-curve 0 0)
(aset! my-curve 1 0)
(aset! my-curve 2 64)
(aset! my-curve 3 200)
(aset! my-curve 4 128)
(aset! my-curve 5 46)
(gimp-curves-spline RUN-NONINTERACTIVE image
HISTOGRAM-VALUE 3 my-curve)
)
