Struct AdjustParams 

Source 
#[repr(C)]
pub struct AdjustParams {
    pub brightness: f32,
    pub contrast: f32,
    pub saturation: f32,
    pub exposure_ev: f32,
    pub gamma: f32,
    pub vibrance: f32,
    pub temperature: f32,
    pub tint: f32,
}
Expand description

Parameters for adjust. Default is neutral — the effect passes frames through visually unchanged.

All controls operate on gamma-encoded RGB (like FFmpeg’s eq filter) and are clamped to their documented range in the shader.

Fields§

§brightness: f32

Additive lift, -1.0..=1.0; 0.0 is neutral.

§contrast: f32

Multiplier around mid-gray, 0.0..=3.0; 1.0 is neutral.

§saturation: f32

0.0 (grayscale) ..=3.0; 1.0 is neutral.

§exposure_ev: f32

Exposure in stops (post-decode, gamma space), -4.0..=4.0; 0.0 is neutral.

§gamma: f32

Output gamma, 0.2..=5.0; 1.0 is neutral. Values above 1.0 brighten mids (applied as pow(c, 1.0 / gamma)).

§vibrance: f32

Saturation boost weighted toward muted colors, -1.0..=1.0; 0.0 is neutral. Skin tones shift less than with saturation.

§temperature: f32

Warm/cool shift, -1.0 (blue) ..=1.0 (orange); 0.0 is neutral.

§tint: f32

Green/magenta shift, -1.0 (green) ..=1.0 (magenta); 0.0 is neutral.
