Properties


Name Type Attribute Description
vertexSrc string public

The vertex shader.

fragmentSrc string public

The fragment shader.

uniforms object public

An object containing the current values of custom uniforms.

padding number public

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 public

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

enabled boolean public

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

autoFit boolean public

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

Methods


apply(filterManager: PIXI.FilterManager, input: PIXI.RenderTarget, output: PIXI.RenderTarget, clear: boolean): void

Applies the filter.

Params:

Name Type Attribute Description
filterManager

The manager.

input

The input target.

output

The output target.

clear

Should the output be cleared before rendering?

Returns:

void


blur(): void

Sets the strength of both the blur.

Returns:

void


quality(): void

Sets the quality of the blur by modifying the number of passes. More passes means higher
quaility bluring but the lower the performance.

Returns:

void


apply(filterManager: PIXI.FilterManager, input: PIXI.RenderTarget, output: PIXI.RenderTarget, clear: boolean): void

Applies the filter.

Params:

Name Type Attribute Description
filterManager

The manager.

input

The input target.

output

The output target.

clear

Should the output be cleared before rendering?

Returns:

void


blur(): void

Sets the strength of both the blur.

Returns:

void


quality(): void

Sets the quality of the blur by modifying the number of passes. More passes means higher
quaility bluring but the lower the performance.

Returns:

void
