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 \(\le\) r,g,b \( \le \) 255, the so-called rgb-value of the color.

Creation

 Color ()
 creates a color with rgb-value (0,0,0), i.e. black.
 
 Color (unsigned char red, unsigned char green, unsigned char blue)
 creates a color with rgb-value (red,green,blue).
 

Operations

bool operator== (const Color &q) const
 Test for equality: Two colors are equal, iff their rgb-values are equal.
 
bool operator!= (const Color &q) const
 Test for inequality.
 
unsigned char red () const
 returns the red component of c.
 
unsigned char green () const
 returns the green component of c.
 
unsigned char blue () const
 returns the blue component of c.
