RGB multi-channel response function¶
RGB response function. By default, uses an CIE colourspace with a D50 white point.
-
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
-
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
