PIXI.filters.AlphaFilter

class AlphaFilter extends PIXI.Filter

Simplest filter - applies alpha.

Use this instead of Container's alpha property to avoid visual layering of individual elements. AlphaFilter applies alpha evenly across the entire display object and any opaque elements it contains. If elements are not opaque, they will blend with each other anyway.

Very handy if you want to use common features of all filters:

Assign a blendMode to this filter, blend all elements inside display object with background.
To use clipping in display coordinates, assign a filterArea to the same container that has this filter.

Constructor

new PIXI.filters.AlphaFilter(alpha: number) → {}

Parameters:
Name	Type	Default	Description
alpha	number	1.0	Amount of alpha from 0 to 1, where 0 is transparent
