plscmap0a: Set cmap0 colors by 8-bit RGB values and  double alpha transparency value 

DESCRIPTION:

    This function is used in examples 30. 

SYNOPSIS:

plscmap0a(r, g, b, alpha, ncol0)

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 PLFLT
    values (0.0 - 1.0) representing the alpha transparency of the
    color. 

    ncol0 (PLINT, input) :    Number of items in the r, g, b, and alpha
    arrays.
