PixiJS

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

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.

fragmentSrc string inherited

The fragment shader.

matrix Array.<number>

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]

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.

uniforms object inherited

An object containing the current values of custom uniforms.

Example

Updating the value of a custom uniform

filter.uniforms.time = performance.now();

vertexSrc string inherited

The vertex shader.

Methods
