Contour
Detects edges with a Sobel filter and draws them as clean outlines
Finds the edges in whatever's below by measuring how fast brightness changes from pixel to pixel (a Sobel filter, the same idea behind pencil-sketch filters), then draws those edges as crisp lines. Great for turning rendered scenes into line art, blueprints or comic-ink looks.
I. Made with Contour
II. Everything else
- Blob Tracker — Locks targeting marks onto what moves below
- CRT — Puts the layers below on a tube screen — scanlines, phosphor and curved glass, or worn VHS tape
- Dither — Ordered dithering of the layers below — into greys, its own colours, or a palette you pick
- Engraving — Redraws the layers below as engraved line work — banknote portrait, cross-hatching or one spiral groove
- Gem Smoke — A logo or word as clear glass with coloured smoke swirling along its walls
- Glitch — Row displacement and scanline injection
- Glyph Dither — ASCII/glyph rendering of the layers below, by brightness
- Grain — Film grain noise, optionally animated
- Halftone — Rebuilds the image as a rotated grid of ink dots, lines or squares
- Heatmap — A logo, word or image seen through a thermal camera — a burning outline, a wide glow, a hot front sweeping across
- Liquid Metal — Turns a logo or word into polished, slowly molten metal — chrome, gold, mercury
- Paper Texture — Prints the picture onto a real sheet — fibres, tooth, crumples, folds and stains, lit from one side
- Pixel Sort — Sorts runs of pixels by brightness into dripping streaks — the glitch-art classic
- Pixelate — Snap coordinates to a coarse block grid
- Posterize — Quantize luminance into a flat color palette
- Subdivide — Break the layers below into blocks that keep splitting, by chance or by detail
- Topo Lines — Draws contour lines through the layers below, like a topographic map of their brightness
