Browser rendering entrypoints for the PODs emitted by @huaqiu/kicad-sexpr-parser. This package bundles the ECAD Viewer canvas, WebGL, viewport, symbol, footprint, schematic, PCB, and stroke/CJK glyph implementations. It does not parse KiCad files and does not define another model layer.
All APIs accept the corresponding boardProto or schematicProto POD from the parser package. Supplying canvas renders into an existing canvas; otherwise a canvas is created. The generated CJK stroke glyph table is bundled in JavaScript, so rendering has no font CDN or network dependency. Standalone renders…
