How it works
Depth Anaglyph 3D estimates relative scene depth, builds left and right views with subpixel bilinear horizontal sampling, and combines them through a gamma-correct Dubois red-cyan color projection. The intensity control scales the actual stereo separation instead of blending an unshifted third ghost into the image. At full strength, near parallax is capped at 1% and far parallax at 2% of image width, while a narrow border safety zone returns both views to the screen plane to avoid clipped edge doubles. Framing and uploaded alpha remain exact in a lossless PNG.
