The Paged PlatformPlugins
Plugins
The five first-party content plugins that extend paged beyond native IDML — vector drawing, web content, raster images, spreadsheets, and database publishing — all built on the Plugin SDK.
BeginnerIexplanation
In short plugins add new kinds of content to a paged document. The five
first-party plugins are built on the same Plugin SDK
contract any third party uses — they're the worked examples. Each renders into the
document through the engine's scene-layer surfaces and persists into the .paged
container.
- paged.drawvector drawing (pen, paths, pathfinder, SVG I/O).
- paged.webHTML/CSS as a content type.
- paged.imageraster processing + PSD round-trip (Rust/WASM, GPU kernels).
- paged.sheeta spreadsheet engine with print-grade layout (Rust/WASM, XLSX round-trip).
- paged.datadatabase publishing + automation (Rust/WASM, DuckDB).
Plus plugin-template — the fork-and-go starter.
