Constructors

  • Parameters

    • Optional noise: number

      The noise intensity, should be a normalized value in the range [0, 1].

    • Optional seed: number

      A random seed for the noise generation. Default is Math.random().

    Returns Pixi.NoiseFilter

Properties

autoFit: boolean

If enabled, PixiJS will fit the filter area into boundaries for better performance. Switch it off if it does not work for specific shader.

Default

true
disposeRunner: Runner<any, any[]>
enabled: boolean

If enabled is true the filter is applied, if false it will not.

legacy: boolean

Legacy filters use position and uvs from attributes (set by filter system)

multisample: null | MSAA_QUALITY

The samples override of the filter instance. If set to null, the sample count of the current render target is used.

Default

PIXI.Filter.defaultMultisample
padding: number

The padding of the filter. Some filters require extra space to breath such as a blur. Increasing this will add extra width and height to the bounds of the object that the filter is applied to.

program: Program

Program that the shader uses.

state: State

The WebGL state the filter requires to render.

uniformGroup: UniformGroup<Dict<any>>
SOURCE_KEY_MAP: Dict<string>

Used for caching shader IDs.

defaultMultisample: null | MSAA_QUALITY

Default filter samples for any filter.

Static

Default

PIXI.MSAA_QUALITY.NONE
defaultResolution: null | number

Default filter resolution for any filter.

Static

Accessors

  • get blendMode(): BLEND_MODES
  • Sets the blend mode of the filter.

    Returns BLEND_MODES

    Default

    PIXI.BLEND_MODES.NORMAL
    
  • set blendMode(value): void
  • Parameters

    Returns void

  • get noise(): number
  • The amount of noise to apply, this value should be in the range (0, 1].

    Returns number

    Default

    0.5
    
  • set noise(value): void
  • Parameters

    • value: number

    Returns void

  • get resolution(): null | number
  • The resolution of the filter. Setting this to be lower will lower the quality but increase the performance of the filter. If set to null or 0, the resolution of the current render target is used.

    Returns null | number

    Default

    PIXI.Filter.defaultResolution
    
  • set resolution(value): void
  • Parameters

    • value: null | number

    Returns void

  • get seed(): number
  • A seed value to apply to the random noise generation. Math.random() is a good value to use.

    Returns number

  • set seed(value): void
  • Parameters

    • value: number

    Returns void

  • get uniforms(): Dict<any>
  • Shader uniform values, shortcut for uniformGroup.uniforms.

    Returns Dict<any>

  • get defaultFragmentSrc(): string
  • The default fragment shader source

    Returns string

  • get defaultVertexSrc(): string
  • The default vertex shader source

    Returns string

Methods

  • Applies the filter

    Parameters

    • filterManager: FilterSystem

      The renderer to retrieve the filter from

    • input: RenderTexture

      The input render target.

    • output: RenderTexture

      The target to output to.

    • Optional clearMode: CLEAR_MODES

      Should the output be cleared before rendering to it.

    • Optional _currentState: FilterState

      It's current state of filter. There are some useful properties in the currentState : target, filters, sourceFrame, destinationFrame, renderTarget, resolution

    Returns void

  • Parameters

    Returns boolean

  • Returns void

  • A short hand function to create a shader based of a vertex and fragment shader.

    Parameters

    • Optional vertexSrc: string

      The source of the vertex shader.

    • Optional fragmentSrc: string

      The source of the fragment shader.

    • Optional uniforms: Dict<any>

      Custom uniforms to use to augment the built-in ones.

    Returns Shader

    A shiny new PixiJS shader!
