Pixel Bender Toolkit Jun 2026

pixel4 p = sampleNearest(src, outCoord()); float gray = (p.r + p.g + p.b) / 3.0; dst = float4(gray, gray, gray, p.a);

Since Adobe archived the official documentation, the best resources are: pixel bender toolkit

newCoord += center;

// Brightness float brightness = 0.2;

Use GLSL (WebGL/OpenGL) or ShaderToy for prototyping image filters. If you have legacy .pbj files, keep a CS6 VM around. pixel4 p = sampleNearest(src, outCoord()); float gray = (p

// Vector from center to current pixel float2 delta = coord - center; float dist = length(delta); pixel4 p = sampleNearest(src
