NAME

       plscol0a -  Set a given color from color map0 by 8 bit RGB value and double alpha value.

SYNOPSIS

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

DESCRIPTION

       Set  a given color by 8-bit RGB value and double alpha value for color  map0 (see the PLplot documentation).  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.

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