| void set_name (const string s) | Function |
Sets name to s. use_name is not reset.
|
| void set_use_name (const bool b) | Function |
Sets use_name to b.
|
| void modify (const real r, [const real g = 0, [const real b = 0]]) | Function |
Adds r, g, and b to red_part,
green_part, and blue_part, respectively. Following the
addition, if red_part, green_part, and/or blue_part
is greater than 1, it is reduced to 1. If it is less than 0, it is
increased to 0.
|
| void set_red_part (const real q) | Function |
| void set_green_part (const real q) | Function |
| void set_blue_part (const real q) | Function |
Let p stand for red_part,
green_part, or blue_part, depending upon which function is
used.
If
0 <= q <= 1,
p is set to q. If
q < 0, p is set to 0.
If q > 1, p is set to 1.
