void Color (void) | Default constructor |
Creates a Color and initializes its red_part ,
green_part , and blue_part to 0. use_name and
on_free_store are set to false .
|
void Color (const Color& c, [const string n = "", [const bool u = true ]])
|
Copy constructor |
Creates a Color and makes it a copy of c. If n is
not the empty string and u is true , use_name is set
to true . Otherwise, its set to false .
|
void Color (const string n, const unsigned short r, const unsigned short g, const unsigned short b, [const bool u = true ])
|
Constructor |
Creates a Color with name n. Its red_part ,
green_part , and blue_part are set to
r/255.0, g/255.0, and b/255.0,
respectively.
use_name is set to u.
|
void set (const string n, const unsigned short r, const unsigned short g, const unsigned short b, [const bool u = false ])
|
Setting function |
Corresponds to the constructor above, except that u is false by default.
|
void Color (const real r, const real g, const real b) | Constructor |
Creates an unnamed Color using the real values r,
g, and b for its red_part , green_part , and
blue_part , respectively.
|
void set (const real r, const real g, const real b) | Setting function |
Corresponds to the constructor above. |
Color* create_new<Color> (const Color* c) | Template specializations |
Color* create_new<Color> (const Color& c) |
Pseudo-constructors for dynamic allocation of Colors .
They create a Color on the free store and allocate memory for it using
new(Color) . They return a pointer to the new Color .
If c is a non-zero pointer or a reference,
the new This function is used in the drawing and filling functions for
