ChromaticSplitEffect

class.NET 6 / 8 / 10.NET Framework 4.8Binarymission.WPF.Shaders.Library.CustomEffects

A pixel shader effect that separates the red and blue channels of its input radially, leaving green in place - the colour fringing a cheap lens leaves at the corners of a photograph.

public class ChromaticSplitEffect : ShaderEffect

Inherits from / implements: ShaderEffect

Remarks

The separation grows with the distance from CenterXY, so the middle of the picture stays sharp and the corners fringe. Animating Displacement over a small range reads as a focus pull; over a large one, as a glitch.

Members at a glance

`ChromaticSplitEffect`	Initializes a new instance of the `ChromaticSplitEffect` class.
`CenterXY`	The point the separation radiates from, in texture coordinates, where (0,0) is the top left of the element and (1,1) the bottom right.
`Displacement`	How far the red and blue channels are pushed apart at the edge of the element. Zero leaves the input untouched; a useful range is about 0.005 to 0.08.
`Input`	The image this effect is applied to. It is set for you when the effect is attached to an element; set it directly only when using the effect as a brush.
`CenterXYProperty`	Identifies the `CenterXY` dependency property.
`DisplacementProperty`	Identifies the `Displacement` dependency property.
`InputProperty`	Identifies the `Input` dependency property.
