Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BrightnessContrast

明るさ・コントラスト (type 1).

Fields

brightness: i32

-100..100.

contrast: i32

-100..100.

Levels(Vec<[f64; 5]>)

レベル補正 (type 2). Per slot: input black, gamma point, input white, output black, output white (0..1).

ToneCurve(Vec<Vec<(f64, f64)>>)

トーンカーブ (type 3). Per slot: control points (0..1).

HueSaturationValue

色相・彩度・明度 (type 4).

Fields

hue: i32

Degrees.

saturation: i32

-100..100.

value: i32

-100..100.

ColorBalance

カラーバランス (type 5).

Fields

preserve_luminosity: bool

輝度を保持.

shadows: [i32; 3]

R, G, B shift of the shadows (-100..100).

midtones: [i32; 3]

R, G, B shift of the midtones (-100..100).

highlights: [i32; 3]

Invert

階調の反転 (type 6).

Posterize(i32)

ポスタリゼーション (type 7): the number of levels.

Threshold(i32)

2値化 (type 8): the threshold.

GradientMap(Ramp)

グラデーションマップ (type 9).
