NAME¶

plscmap1a - Set color map1 colors using 8-bit RGB values and double alpha values.

SYNOPSIS¶

plscmap1a(r, g, b, a, ncol1)

DESCRIPTION¶

Set color map1 colors using 8-bit RGB values (see the PLplot documentation) and double alpha values. This also sets the number of colors. This function is used in example 31.

ARGUMENTS¶

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.

a (PLFLT *, input)

Pointer to array with set of double values (0.0-1.0) representing the alpha value of the color.

ncol1 (PLINT, input)

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