| void operator= (const Color& c) | Assignment operator |

false, and red_part, green_part, and
blue_part to c.red_part, c.green_part, and
c.blue_part, respectively.
|
| bool operator== (const Color& c) | const operator |
Equality operator. Returns true, if the red_parts,
green_parts, and blue_parts of *this and c
are equal, otherwise false. The names and
use_names are not compared.
|
| bool operator!= (const Color& c) | const operator |
Inequality operator. Returns false, if the red_parts,
green_parts, and blue_parts of *this and c
are equal, otherwise true. The names and
use_names are not compared.
|
| ostream& operator<< (ostream& o, const Color& c) | Non-member function |
Output operator. Writes the MetaPost code for the Color to
out_stream when a Picture is output. This occurs when
the Color has been used as an argument to
