Struct ButteraugliParams 

pub struct ButteraugliParams { /* private fields */ }

Butteraugli parameters (from butteraugli).

Configure intensity target, HF asymmetry, and other parameters. Butteraugli comparison parameters.

Use the builder pattern to construct:

use butteraugli::ButteraugliParams;

let params = ButteraugliParams::new()
    .with_intensity_target(250.0)  // HDR display
    .with_hf_asymmetry(1.5)        // Penalize new artifacts more
    .with_compute_diffmap(true);   // Generate per-pixel difference map

Implementations

impl ButteraugliParams

pub fn new() -> ButteraugliParams

Creates a new ButteraugliParams with default values.

pub fn with_intensity_target(self, intensity_target: f32) -> ButteraugliParams

Sets the intensity target (display brightness in nits).

pub fn with_hf_asymmetry(self, hf_asymmetry: f32) -> ButteraugliParams

Sets the HF asymmetry multiplier. Values > 1.0 penalize new high-frequency artifacts more than blurring.

pub fn with_xmul(self, xmul: f32) -> ButteraugliParams

Sets the X channel multiplier.

pub fn with_compute_diffmap(self, compute_diffmap: bool) -> ButteraugliParams

Sets whether to compute the per-pixel difference map.

When true, the result will include an ImgVec<f32> difference map. When false (default), the diffmap field will be None, which is faster.

pub fn hf_asymmetry(&self) -> f32

Returns the HF asymmetry multiplier.

pub fn xmul(&self) -> f32

Returns the X channel multiplier.

pub fn intensity_target(&self) -> f32

Returns the intensity target in nits.

pub fn compute_diffmap(&self) -> bool

Returns whether to compute the per-pixel difference map.
