CGAL::Color

Definition

An object of the class Color is a color available for drawing operations in many Cgal output streams. Each color is defined by a triple of unsigned chars (r,g,b) with 0 ≤ r,g,b ≤ 255, the so-called rgb-value of the color.

#include <CGAL/IO/Color.h>

Creation

Color c;
	creates a color with rgb-value (0,0,0), i.e. black.

Color c ( unsigned char red, unsigned char green, unsigned char blue);
	creates a color with rgb-value (red,green,blue).

Operations

bool	c == q const	Test for equality: Two colors are equal, iff their rgb-values are equal.
bool	c != q const	Test for inequality.

unsigned char	c.red () const	returns the red component of c.
unsigned char	c.green () const	returns the green component of c.
unsigned char	c.blue () const	returns the blue component of c.

Constants

The following constants are predefined:

const Color	BLACK = Color(0, 0, 0);	Black.
const Color	WHITE = Color(255, 255, 255);	White.
const Color	RED = Color(255, 0, 0);	Red.
const Color	GREEN = Color(0, 255, 0);	Green.
const Color	BLUE = Color(0, 0, 255);	Blue.
const Color	VIOLET = Color(255, 0, 255);	Violet.
const Color	ORANGE = Color(255, 170, 0);	Orange.
