Detailed Description

A color made from red, green, blue and alpha floating-point values in [0..1] range.

Constructor & Destructor Documentation

Color::Color ( )

noexcept

Create black color.

Color::Color ( int  red, int  green, int  blue, int  alpha = 255  )

noexcept

Create a color from red, green, blue and alpha numeric values. Values must be in [0..255] range.

Color::Color ( float  red, float  green, float  blue, float  alpha = 1.0f  )

noexcept

Create a color from red, green, blue and alpha floating-point values. Values must in [0..1] range.

Color::Color ( const Color &  color )

noexcept

Create a color by copying another color.

Color::Color ( const Color &  color1, const Color &  color2, float  u  )

noexcept

Create a color by linearly interpolating two other colors.

Member Function Documentation

static Color Color::fromHSL ( float  hue, float  saturation, float  lightness, float  alpha = 1.0f  )

static

Create a color specified by hue, saturation and lightness. Values must in [0..1] range.

static Color Color::fromHTML ( const char *  rgb, float  alpha = 1.0f  )

static

Create a color from a HTML string like "#333" or "#112233".

void Color::interpolate ( const Color &  other, float  u  )

noexcept

Linearly interpolate this color against another.

bool Color::isEqual ( const Color &  color, bool  withAlpha = true  )

noexcept

Check if this color matches another.

Note

: Comparison is forced within 8-bit color values.

void Color::fixBounds ( )

noexcept

Fix color bounds if needed.

Member Data Documentation

union { ... }

Direct access to the color values.
