Class: NoiseFilter


A Noise effect filter.

original filter:

new PIXI.filters.NoiseFilter (noise, seed) overrides

Name Type Attributes Default Description
noise number <optional>

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

seed number <optional>

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



noise number

The amount of noise to apply, this value should be in the range (0, 1].

Default Value:
  • 0.5

seed number

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

Inherited Properties

From class PIXI.Filter

autoFit boolean inherited

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 Value:
  • true

Sets the blend mode of the filter.

Default Value:

enabled boolean inherited

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

legacy boolean readonly inherited

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

The samples of the filter.

padding number inherited

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.

resolution number inherited

The resolution of the filter. Setting this to be lower will lower the quality but increase the performance of the filter.

The WebGL state the filter requires to render.

From class PIXI.Shader

Program that the shader uses.

uniforms Dict<any> readonly inherited

Shader uniform values, shortcut for uniformGroup.uniforms.

Inherited Methods

From class PIXI.Filter

apply (filterManager, input, output, clearMode, currentState) void inherited

Applies the filter

Name Type Attributes Description
filterManager PIXI.FilterSystem

The renderer to retrieve the filter from

input PIXI.RenderTexture

The input render target.

output PIXI.RenderTexture

The target to output to.

clearMode PIXI.CLEAR_MODES <optional>

Should the output be cleared before rendering to it.

currentState object <optional>

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