plscmap1: Set color map1 colors using 8-bit RGB values

plscmap1 (r, g, b, ncol1);

Set color map1 colors using 8-bit RGB values (see the Section called Color Map1 in Chapter 3). This also sets the number of colors.

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.

ncol1 (PLINT, input)

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