plscmap1a: Set cmap1 colors using 8-bit RGB values and double alpha transparency values 

DESCRIPTION:

    This function is used in example 31. 

SYNOPSIS:

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

ARGUMENTS:

    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, b, and alpha
    arrays.
