DuotoneEffect

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

A pixel shader effect that maps the brightness of its input onto a two-colour ramp - the darkest pixels become ShadowColor, the brightest HighlightColor, and everything else a blend of the two.

public class DuotoneEffect : ShaderEffect

Inherits from / implements: ShaderEffect

Remarks

The brightness is measured on the straight colour rather than the premultiplied one WPF hands the shader, so semi-transparent pixels map where they look as though they should. Strength mixes the result back towards the original, so the effect can be dialled in rather than only switched on.
