plscmap0 (r, g, b, ncol0);

Set color map0 colors using 8-bit RGB values (see the Section called Color Map0 in Chapter 3). This sets the entire color map – only as many colors as specified will be allocated.

r (PLINT *, input)

Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of red in the color.

g (PLINT *, input)

Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of green in the color.

b (PLINT *, input)

Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of blue in the color.

ncol0 (PLINT, input)

Number of items in the r, g, and b arrays.

Redacted form: plscmap0(r, g, b, ncol0)
