Class Documentation

class RGB_t : public wt::sensor::response::response_t

Multi-channel RGB response function. Internally, converts spectral data to XYZ and then to RGB. Conversion depends on the desired RGB colourspace and white point. Defaults to CIE colourspace with a D50 white point.

Public Functions

inline RGB_t(std::string id, const wt::wt_context_t &context, std::shared_ptr<tonemap_t> tonemap, colourspace::RGB_colourspace_e colourspace, colourspace::white_point_e whitepoint)

RGB_t(RGB_t&&) = default

virtual ~RGB_t() noexcept = default

inline const auto &get_XYZ_to_RGB_matrix() const noexcept

Returns the XYZ-to-RGB conversion matrix used by this RGB response function.

inline auto get_RGB_colourspace() const noexcept

Returns the colourspace of this RGB response function.

inline auto get_whitepoint() const noexcept

Returns the white point of this RGB response function.

inline virtual bitmap::pixel_layout_t pixel_layout() const noexcept override

Returns the response function’s pixel layout.

virtual const f_t f(std::uint32_t channel, const wavenumber_t &k) const noexcept override

Evaluates the sensor sensitivity function.

inline virtual const spectrum::spectrum_real_t &sensitivity() const noexcept override

Returns the sensor’s sensitivity spectrum (the sum of all channels’ response spectra)
