Function Documentation

static double ColorConverter::clamp ( double  x, double  a, double  b  )

static

static void ColorConverter::hslToRgb ( double  h, double  s, double  l, byte  rgb[]  )

static

Converts an HSL color value to RGB. Conversion formula adapted from http://en.wikipedia.org/wiki/HSL_color_space. Assumes h, s, and l are contained in the set [0, 1] and returns r, g, and b in the set [0, 255].

Parameters

double	h The hue
double	s The saturation
double	l The lightness

Returns

byte rgb[] The RGB representation

static void ColorConverter::hsvToRgb ( double  h, double  s, double  v, byte  rgb[]  )

static

Converts an HSV color value to RGB. Conversion formula adapted from http://en.wikipedia.org/wiki/HSV_color_space. Assumes h, s, and v are contained in the set [0, 1] and returns r, g, and b in the set [0, 255].

Parameters

double	h The hue
double	s The saturation
double	v The value

Returns

byte rgb[] The RGB representation

static double ColorConverter::hue2rgb ( double  h, double  m1, double  m2  )

static

static void ColorConverter::rgbToHsl ( byte  r, byte  g, byte  b, double  hsl[]  )

static

Converts an RGB color value to HSL. Conversion formula adapted from http://en.wikipedia.org/wiki/HSL_color_space. Assumes r, g, and b are contained in the set [0, 255] and returns h, s, and l in the set [0, 1].

Parameters

byte	r The red color value
byte	g The green color value
byte	b The blue color value
double	hsl[] The HSL representation

static void ColorConverter::rgbToHsv ( byte  r, byte  g, byte  b, double  hsv[]  )

static

Converts an RGB color value to HSV. Conversion formula adapted from http://en.wikipedia.org/wiki/HSV_color_space. Assumes r, g, and b are contained in the set [0, 255] and returns h, s, and v in the set [0, 1].

Parameters

byte	r The red color value
byte	g The green color value
byte	b The blue color value

Returns

double hsv[] The HSV representation
