7       double alpha value.

SYNOPSIS

10       plscol0a(icol0, r, g, b, a)
11

DESCRIPTION

13       Set a given color by 8-bit RGB value and double alpha value  for  color
14       map0  (see  the  PLplot  documentation).  Overwrites the previous color
15       value  for the given index and, thus, does not result in any additional
16       allocation  of space for colors.
17
18       This function is used in example 30.

ARGUMENTS

21       icol0 (PLINT, input)
22              Color  index.   Must  be  less than the maximum number of colors
23              (which is set by default,  by  plscmap0n(3plplot),  or  even  by
24              plscmap0(3plplot)).
25
26       r (PLINT, input)
27              Unsigned 8-bit integer (0-255) representing the degree of red in
28              the color.
29
30       g (PLINT, input)
31              Unsigned 8-bit integer (0-255) representing the degree of  green
32              in the color.
33
34       b (PLINT, input)
35              Unsigned  8-bit  integer (0-255) representing the degree of blue
36              in the color.
37
38       a (PLFLT, input)
39              double value (0.0-1.0)  representing  the  alpha  value  of  the
40              color.
