Package-level declarations

Types

class BlurFilter(radius: Double = 4.0, expandBorder: Boolean = true, var optimize: Boolean = true) : ComposedFilter, FilterWithFiltering

ColorMatrixFilter

class ColorMatrixFilter(colorMatrix: Matrix4, blendRatio: Double = 1.0) : ShaderFilter

A Filter applying a complex color transformation to the view.

ColorTransformFilter

class ColorTransformFilter(colorTransform: ColorTransform) : ShaderFilter

A Filter applying a multiplicative and additive color transformation to the view.

ComposedFilter

open class ComposedFilter : Filter

Allows to create a single Filter that will render several filters in order.

Convolute3Filter

class Convolute3Filter(var kernel: Matrix4, dist: Double = 1.0, applyAlpha: Boolean = false) : ShaderFilter

A Filter that will convolute near pixels (3x3) with a kernel. https://en.wikipedia.org/wiki/Kernel_(image_processing)

DirectionalBlurFilter

class DirectionalBlurFilter(var angle: Angle = 0.degrees, var radius: Double = 4.0, var expandBorder: Boolean = true) : ShaderFilter

DitheringFilter

class DitheringFilter(levels: Double = 4.0) : ShaderFilter

DropshadowFilter

open class DropshadowFilter(var dropX: Double = 10.0, var dropY: Double = 10.0, var shadowColor: RGBA = Colors.BLACK.withAd(0.75), var blurRadius: Double = 4.0, var smoothing: Boolean = true) : FilterWithFiltering

Filter

interface Filter

Interface for View filters.

FilterWithFiltering

interface FilterWithFiltering : Filter

FlagFilter

class FlagFilter(amplitude: Double = 80.0, crestCount: Double = 5.0, cyclesPerSecond: Double = 2.0, time: TimeSpan = 0.seconds) : ShaderFilter

A Flag Filter that distorts the texture using increasing waves to the right, keeping the left-most vertical static, as if connected to a flag pole.

IdentityFilter

open class IdentityFilter(val smoothing: Boolean) : Filter

Simple Filter that draws the texture pixels without any kind of transformation

PageFilter

class PageFilter(hratio: Ratio = Ratio.ZERO, hamplitude0: Double = 0.0, hamplitude1: Double = 10.0, hamplitude2: Double = 0.0, vratio: Ratio = Ratio.HALF, vamplitude0: Double = 0.0, vamplitude1: Double = 0.0, vamplitude2: Double = 0.0) : ShaderFilter

A filter that simulates a page of a book.

RenderToTextureResult

class RenderToTextureResult : Disposable

ShaderFilter

abstract class ShaderFilter : FilterWithFiltering

Abstract class for Views that paints the Texture using a FragmentShader (fragment).

SwizzleColorsFilter

class SwizzleColorsFilter(initialSwizzle: String = "rgba") : ShaderFilter

Allows to swizzle (interchange) color components via the swizzle property.

TransitionFilter

class TransitionFilter(var transition: TransitionFilter.Transition = Transition.CIRCULAR, reversed: Boolean = false, spread: Double = 1.0, ratio: Ratio = Ratio.ONE, filtering: Boolean = false) : ShaderFilter

ViewRenderPhaseBackdropFilter

class ViewRenderPhaseBackdropFilter(var filter: Filter) : ViewRenderPhase

ViewRenderPhaseFilter

class ViewRenderPhaseFilter(var filter: Filter? = null) : ViewRenderPhase

WaveFilter

class WaveFilter(amplitude: Vector2D = Vector2D(10, 10), crestDistance: Vector2D = Vector2D(16, 16), cyclesPerSecond: Vector2D = Vector2D(1, 1), time: TimeSpan = 0.seconds) : ShaderFilter

A Wave Filter that distorts the texture using waves.

Properties

backdropFilter

var View.backdropFilter: Filter?

DummyFilter

val DummyFilter: IdentityFilter.Companion

filter

var View.filter: Filter?

An optional Filter attached to this view. Filters allow to render this view to a texture, and to control how to render that texture (using shaders, repeating the texture, etc.). You add multiple filters by creating a composite filter ComposedFilter.

filterScale

var View.filterScale: Double

Usually a value between 0.0, 1.0

registerFilterSerialization

var Views.registerFilterSerialization: Boolean
