Package-level declarations

Types

class Brightness(val factor: Float) : EffectSpec

Multiply every color channel of the frame.

class ColorMatrix(val rr: Float = 1.0f, val rg: Float = 0.0f, val rb: Float = 0.0f, val rBias: Float = 0.0f, val gr: Float = 0.0f, val gg: Float = 1.0f, val gb: Float = 0.0f, val gBias: Float = 0.0f, val br: Float = 0.0f, val bg: Float = 0.0f, val bb: Float = 1.0f, val bBias: Float = 0.0f) : EffectSpec

Recombine the color channels of every pixel through a 3x3 matrix and an offset.

class Contrast(val factor: Float) : EffectSpec

Stretch or flatten every color channel about mid grey.

class HueRotate(val degrees: Float) : EffectSpec

Turn every hue around the color wheel by the same angle.

class Invert(val amount: Float = 1.0f) : EffectSpec

Turn every color into its negative.

class RgbAdjustment(val red: Float = 1.0f, val green: Float = 1.0f, val blue: Float = 1.0f) : EffectSpec

Multiply each color channel by its own factor.

class Saturation(val factor: Float) : EffectSpec

Move every pixel towards or away from its own grey.

class Sepia(val amount: Float = 1.0f) : EffectSpec

Tone the frame towards the warm brown of an old photograph.

Functions

fun EffectsBuilder.brightness(factor: Float): EffectsBuilder

Multiply every color channel by factor, where 1f leaves the frame unchanged.

fun EffectsBuilder.colorMatrix(matrix: ColorMatrix): EffectsBuilder

Recombine the color channels through a matrix. See ColorMatrix for how the entries are read.

fun EffectsBuilder.contrast(factor: Float): EffectsBuilder

Stretch every color channel about mid grey by factor, where 1f leaves the frame unchanged.

fun EffectsBuilder.grayscale(): EffectsBuilder

Turn the frame monochrome, keeping each pixel's Rec. 709 luma.

fun EffectsBuilder.hueRotate(degrees: Float): EffectsBuilder

Turn every hue by degrees, where 0f leaves the frame unchanged.

fun EffectsBuilder.invert(amount: Float = 1.0f): EffectsBuilder

Invert every color by amount, where 1f is the full negative.

fun EffectsBuilder.rgbAdjustment(red: Float = 1.0f, green: Float = 1.0f, blue: Float = 1.0f): EffectsBuilder

Multiply each color channel by its own factor, where 1f leaves a channel unchanged.

fun EffectsBuilder.saturation(factor: Float): EffectsBuilder

Scale how far every pixel sits from its own grey by factor, where 1f leaves the frame unchanged.

fun EffectsBuilder.sepia(amount: Float = 1.0f): EffectsBuilder

Tone the frame sepia by amount, where 1f is fully toned.
