Library with shader effects for use with WPF.

Build

The projects makes use of the Shader Effects BuildTask from WPF Futures. Since some of the effects require pixel shader 3.0 ShaderBuildTask.dll needs to be replaced with a modified version.

To do so install Shader Effects BuildTask and copy the provided version under \ShaderEffectLibrary\ to %WinDir%\assembly\GAC_32\ShaderBuildTask%Version% as administrator or use the gacutil. This allows you to compile .fx files under the ps_3_0 profile.

You might also need to install the DirectX End-User Runtimes

Effects

AdjustChromaEffect

Adjusts the chroma value of a target texture in the HCY' color space.

Parameters

  • Input: Brush that acts as the input
  • Delta: Chroma change between -1.0 and 1.0

AdjustHueEffect

Adjusts the hue of a target texture.

Parameters

  • Input: Brush that acts as the input
  • Delta: Hue change between -1.0 and 1.0

AdjustLightnessEffect

Adjusts the lightness of a target texture.

Parameters

  • Input: Brush that acts as the input
  • Delta: Lightness change between -1.0 and 1.0

AdjustLumaEffect

Adjusts the luma value of a target texture in the HCY' color space.

Parameters

  • Input: Brush that acts as the input
  • Delta: Luma change between -1.0 and 1.0
  • Coefficients: Coefficients that are considered when weighting the RGB channels of the input (one components for each channel between 0 and 1.0)

Predefined coefficients

  • Rec609: ITU-R Recommendation BT.601 standard
  • Rec709: ITU-R Recommendation BT.709 standard
  • SMPTE240M: SMPTE 240M specification
