Detailed Description

Utility class for manpulating RGBA colors.

sf::Color is a simple color class composed of 4 components:

Red
Green
Blue
Alpha (opacity)

Each component is a public member, an unsigned integer in the range [0, 255]. Thus, colors can be constructed and manipulated very easily:

 sf::Color c1(255, 0, 0); // red
 c1.red = 0;              // make it black
 c1.blue = 128;           // make it dark blue

The fourth component of colors, named "alpha", represents the opacity of the color. A color with an alpha value of 255 will be fully opaque, while an alpha value of 0 will make a color fully transparent, whatever the value of the other components.

The most common colors are already defined as static variables:

 sf::Color black   = sf::Color::Black;
 sf::Color white   = sf::Color::White;
 sf::Color red     = sf::Color::Red;
 sf::Color green   = sf::Color::Green;
 sf::Color blue    = sf::Color::Blue;
 sf::Color yellow  = sf::Color::Yellow;
 sf::Color magenta = sf::Color::Magenta;
 sf::Color cyan    = sf::Color::Cyan;

Colors can also be added and modulated (multiplied) using the overloaded operators + and *.

Constructor & Destructor Documentation

sf::Color::Color ( )

Default constructor.

Constructs an opaque black color. It is equivalent to sf::Color(0, 0, 0, 255).

Definition at line 48 of file Color.cpp.

sf::Color::Color	(	Uint8	red,
		Uint8	green,
		Uint8	blue,
		Uint8	alpha = `255`
	)

Construct the color from its 4 RGBA components.

Parameters:

	red	Red component (in the range [0, 255])
	green	Green component (in the range [0, 255])
	blue	Blue component (in the range [0, 255])
	alpha	Alpha (opacity) component (in the range [0, 255])
