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.
