Detailed Description

Representation of a color.

The color is defined as red, green, and blue intensities as well as an alpha representation of transparency (RGBA). The class provides mechanisms to retrieve the color as 8-bit integers or floating point values in the range [0, 1].

Constructor & Destructor Documentation

Color() [1/3]

viskores::rendering::Color::Color ( )

inline

Create a black color.

Color() [2/3]

viskores::rendering::Color::Color ( viskores::Float32  r_, viskores::Float32  g_, viskores::Float32  b_, viskores::Float32  a_ = 1.f  )

inline

Create a color with specified RGBA values.

The values are floating point and in the range [0, 1].

Color() [3/3]

viskores::rendering::Color::Color ( const viskores::Vec4f_32 &  components )

inline

Create a color with specified RGBA values.

The values are floating point and in the range [0, 1].

Member Function Documentation

GetComponentAsByte()

viskores::UInt8 viskores::rendering::Color::GetComponentAsByte ( int  i )

inline

GetRGBA()

void viskores::rendering::Color::GetRGBA ( viskores::UInt8 &  r, viskores::UInt8 &  g, viskores::UInt8 &  b, viskores::UInt8 &  a  )

inline

RawBrightness()

viskores::Float64 viskores::rendering::Color::RawBrightness ( )

inline

SetComponentFromByte()

void viskores::rendering::Color::SetComponentFromByte ( viskores::Int32  i, viskores::UInt8  v  )

inline

Set the color value from 8 bit RGBA components.

The components are packed together into a 32-bit (4-byte) values.
