Class: ColorMatrixFilter

PIXI.filters.ColorMatrixFilter

The ColorMatrixFilter class lets you apply a 5x4 matrix transformation on the RGBA color and alpha values of every pixel on your displayObject to produce a result with a new set of RGBA color and alpha values. It's pretty powerful!

 let colorMatrix = new PIXI.filters.ColorMatrixFilter();
 container.filters = [colorMatrix];
 colorMatrix.contrast(2);

Members

alpha number

The opacity value to use when mixing the original and resultant colors.

When the value is 0, the original color is used without modification. When the value is 1, the result color is used. When in the range (0, 1) the color is interpolated between the original and result by this amount.

Default Value:
  • 1

matrix Array

The matrix of the color matrix filter

Default Value:
  • [1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0]

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.

blendMode number inherited

Sets the blendmode of the filter

Default Value:
  • PIXI.BLEND_MODES.NORMAL

enabled boolean inherited

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

legacy boolean inherited

Legacy filters use position and uvs from attributes

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 object 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

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

From class PIXI.Shader

destroy () void inherited
