NAME
       plscol0a -  Set 8-bit  RGB values and double alpha transparency value for given cmap0 color index


SYNOPSIS
       plscol0a(icol0, r, g, b, alpha)


DESCRIPTION
       Set  8-bit  RGB  value and double alpha transparency value for given cmap0 (see the PLplot documentation)
       index.  Overwrites the previous color value  for the given index  and,  thus,  does  not  result  in  any
       additional allocation  of space for colors.

       This function is used in example 30.


ARGUMENTS
       icol0 (PLINT, input)
              Color  index.   Must  be  less  than  the  maximum  number  of colors (which is set by default, by
              plscmap0n(3plplot), or even by plscmap0(3plplot)).

       r (PLINT, input)
              Unsigned 8-bit integer (0-255) representing the degree of red in the color.

       g (PLINT, input)
              Unsigned 8-bit integer (0-255) representing the degree of green in the color.

       b (PLINT, input)
              Unsigned 8-bit integer (0-255) representing the degree of blue in the color.

       alpha (PLFLT, input)
              double value (0.0-1.0) representing the alpha transparency value of the color.
