NAME

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

SYNOPSIS

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

DESCRIPTION

       Set 8-bit RGB value and PLFLT 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(3plplot), 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(3plplot), input)
              Unsigned 8-bit integer (0-255) representing the degree of red in the color.

       g (PLINT(3plplot), input)
              Unsigned 8-bit integer (0-255) representing the degree of green in the color.

       b (PLINT(3plplot), input)
              Unsigned 8-bit integer (0-255) representing the degree of blue in the color.

       alpha (PLFLT(3plplot), input)
              Value of the alpha transparency in the range (0.0-1.0).
