Struct RecOetf 

Source 
pub struct RecOetf;
Expand description

The opto-electronic transfer function used in standard dynamic range (SDR) standards by the ITU-R such as Rec709 and Rec2020.

RecOetf will not use any kind of approximation when converting from T to T. This involves calls to powf, which may make it too slow for certain applications.

There are some specialized cases where it has been optimized:

  • When converting from u8 to f32 or f64, while converting to linear space. This uses lookup tables with precomputed values.
  • When converting from f32 or f64 to u8, while converting from linear space. This uses a fast algorithm that guarantees a maximum error in the result of less than 0.6 in line with this DirectX spec.
