r
(const PLINT *
, input)
Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of red in the color.
g
(const PLINT *
, input)
Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of green in the color.
b
(const PLINT *
, input)
Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of blue in the color.
alpha
(const PLFLT *
, input)
Pointer to array with set of double values (0.0-1.0) representing the alpha transparency value of the color.
ncol1
(PLINT
, input)
Number of items in the
,
r
,
g
, and
b
arrays.
alpha
Redacted form: plscmap1a(r, g, b, alpha)
