Class: NoiseFilter


A Noise effect filter.

new PIXI.filters.NoiseFilter (noise, seed)

Name Type Default Description
noise number 0.5

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

seed number

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



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.

blendMode number inherited

Sets the blendmode of the filter

Default Value:

enabled boolean inherited

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

fragmentSrc string inherited

The fragment shader.

noise number

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

Default Value:
  • 0.5

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.

seed number

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

uniforms object inherited

An object containing the current values of custom uniforms.


Updating the value of a custom uniform

filter.uniforms.time =;

vertexSrc string inherited

The vertex shader.


apply (filterManager, input, output, clear, currentState) inherited

Applies the filter

Name Type Description
filterManager PIXI.FilterManager

The renderer to retrieve the filter from

input PIXI.RenderTarget

The input render target.

output PIXI.RenderTarget

The target to output to.

clear boolean

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
