Member Function Documentation

build()

gamma_table neo::gamma_table::build ( float  gamma )

static

Builds a lookup gamma table from sRGB values to the corresponding gamma-corrected intensity values. The returned table implements essentially gamma(srgb_to_linear(v)).

operator[]()

std::uint8_t neo::gamma_table::operator[] ( std::uint8_t  v ) const

inline

reverse_lookup()

std::uint8_t neo::gamma_table::reverse_lookup

(

std::uint8_t

v

)

const

Note

This bisects lut, so it's very slow.
