Class: BlurFilter


The BlurFilter applies a Gaussian blur to an object.

The strength of the blur can be set for the x-axis and y-axis separately.

new PIXI.filters.BlurFilter (strength, quality, resolution, kernelSize) overrides

Name Type Attributes Default Description
strength 8

The strength of the blur filter.

quality 4

The quality of the blur filter.

resolution <optional>

The resolution of the blur filter.

kernelSize 5

The kernelSize of the blur filter.Options: 5, 7, 9, 11, 13, 15.



Sets the blendmode of the filter

Default Value:

blur number

Sets the strength of both the blurX and blurY properties simultaneously

Default Value:
  • 2

blurX number

Sets the strength of the blurX property

Default Value:
  • 2

blurY number

Sets the strength of the blurY property

Default Value:
  • 2

quality number

Sets the number of passes for blur. More passes means higher quality bluring.

Default Value:
  • 1

repeatEdgePixels boolean

If set to true the edge of the target will be clamped

Default Value:
  • false


apply (filterManager, input, output, clearMode) void overrides

Applies the filter.

Name Type Description
filterManager PIXI.FilterSystem

The manager.

input PIXI.RenderTexture

The input target.

output PIXI.RenderTexture

The output target.


How to clear

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

enabled boolean inherited

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

Default Value:
  • true

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.

Default Value:
  • 0

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.
