Struct Srgb

source 
pub struct Srgb;
Expand description

The sRGB standard, color space, and transfer function.

§As transfer function

Srgb 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. f32 will use the table provided by fast_srgb8::srgb8_to_f32.
  • When converting from f32 or f64 to u8, while converting from linear space. This uses fast_srgb8::f32_to_srgb8.
