Test helpers for Sealpixel plugin authors: pinned render goldens (checkPluginParity) and property-based fuzzing (fuzzPlugin).

Solid, inset and polaroid frames drawn inside the image bounds.

Build Sealpixel plugins: definePlugin, defineOperation, and deterministic math helpers for JS kernels.

Brightness, contrast, saturation, exposure, gamma, clarity and vignette adjustments.

Rectangles, ellipses, lines, arrows, freehand paths and text over the image. Fonts are hashed assets so client and server rasterise identical glyphs.

Crop, rotate and flip operations for the Sealpixel image editor.

Place image assets (stickers, logos) in crop space with rotation, flips and opacity.

Pixelate or blur rectangular and freeform regions. Built for anonymisation: cells snap to the source grid so proxy and full renders match.

Image or text watermark at an anchor or tiled across the image.

Background fill colour for areas exposed by crop or rotation.

Resize to a target size with contain, cover and fill modes.

Colour filter presets (grayscale, sepia, vintage, cool, warm) and custom colour matrices.

Default, themeable Sealpixel editor UI as Web Components (Lit). Optional: the core is headless.

Drop-in <sealpixel-editor> with all first-party plugins and a bundled render worker. Import once, use the tag.

Astro integration for the Sealpixel image editor: Vite config for the wasm and worker, a <SealpixelEditor /> component, and an optional /api/sealpixel/render endpoint.

The Sealpixel image editor in one install: re-exports @sealpixel/element, so `import 'sealpixel'` registers <sealpixel-editor> with every first-party plugin.

All first-party Sealpixel plugins, with `defaultPlugins` and `allPlugins`.

General utilities for plugins to use

Sealpixel headless core: edit log types, compile(), render(), editor session. Runtime-agnostic.
