Builder

class Builder

kotlin.Any
↳	androidx.palette.graphics.Target.Builder

Builder class for generating custom Target instances.

Summary

Public constructors
`<init>()` Create a new `Target` builder from scratch.
`<init>(@NonNull target: Target)` Create a new builder based on an existing `Target`.

Public methods
Target.Builder	`setMinimumLightness(value: Float)` Set the minimum lightness value for this target.
Target.Builder	`setTargetSaturation(value: Float)` Set the target/ideal saturation value for this target.
Target.Builder	`setMaximumSaturation(value: Float)` Set the maximum saturation value for this target.
Target.Builder	`setMaximumLightness(value: Float)` Set the maximum lightness value for this target.
Target	`build()` Builds and returns the resulting `Target`.
Target.Builder	`setExclusive(exclusive: Boolean)` Set whether any color selected for this target is exclusive to this target only.
Target.Builder	`setPopulationWeight(weight: Float)` Set the weight of importance that this target will place on a color's population within the image.
Target.Builder	`setMinimumSaturation(value: Float)` Set the minimum saturation value for this target.
Target.Builder	`setTargetLightness(value: Float)` Set the target/ideal lightness value for this target.
Target.Builder	`setLightnessWeight(weight: Float)` Set the weight of importance that this target will place on lightness values.
Target.Builder	`setSaturationWeight(weight: Float)` Set the weight of importance that this target will place on saturation values.

Builder()

Create a new Target builder from scratch.

Builder(@NonNull target: Target)

Create a new builder based on an existing Target.

@NonNull fun setMinimumLightness(value: Float): Target.Builder

Set the minimum lightness value for this target.

@NonNull fun setTargetSaturation(value: Float): Target.Builder

Set the target/ideal saturation value for this target.

@NonNull fun setMaximumSaturation(value: Float): Target.Builder

Set the maximum saturation value for this target.

@NonNull fun setMaximumLightness(value: Float): Target.Builder

Set the maximum lightness value for this target.

@NonNull fun build(): Target

Builds and returns the resulting Target.

@NonNull fun setExclusive(exclusive: Boolean): Target.Builder

Set whether any color selected for this target is exclusive to this target only. Defaults to true.

Parameters
`exclusive`	Boolean: true if any the color is exclusive to this target, or false is the color can be selected for other targets.

@NonNull fun setPopulationWeight(weight: Float): Target.Builder

Set the weight of importance that this target will place on a color's population within the image.

The larger the weight, relative to the other weights, the more important that a color's population being close to the most populous has on selection.

A weight of 0 means that it has no weight, and thus has no bearing on the selection.

@NonNull fun setMinimumSaturation(value: Float): Target.Builder

Set the minimum saturation value for this target.

@NonNull fun setTargetLightness(value: Float): Target.Builder

Set the target/ideal lightness value for this target.

@NonNull fun setLightnessWeight(weight: Float): Target.Builder

Set the weight of importance that this target will place on lightness values.

The larger the weight, relative to the other weights, the more important that a color being close to the target value has on selection.

A weight of 0 means that it has no weight, and thus has no bearing on the selection.

@NonNull fun setSaturationWeight(weight: Float): Target.Builder

Set the weight of importance that this target will place on saturation values.

The larger the weight, relative to the other weights, the more important that a color being close to the target value has on selection.

A weight of 0 means that it has no weight, and thus has no bearing on the selection.
