History

Danila Poyarkov f55b887d2b feat(scene-graph)!: make a stroke a paint (#864 ) * feat(scene-graph)!: make a stroke a paint Stroke extends Fill, so a stroke carries the same paint vocabulary a fill does instead of a lone color. Every construction site now states a solid paint type, which keeps today's behaviour exactly; rendering, .fig conversion, and the stroke panel still read solid strokes only. copyFill is generic over the paint shape so copyStroke reuses it rather than repeating the deep copy of gradient stops, transforms and pattern fields. Groundwork for the gradient and image strokes in #797. * test(scene-graph): cover a stroke's nested paint data in copyStroke A stroke is a paint now, so its gradient stops and transform must copy as deeply as a fill's; the fixture was solid and proved only the color and dash pattern.		2026-10-04 13:38:05 +04:00

@open-pencil/fig

.fig file-format package for OpenPencil.

The package owns the outer .fig archive boundary and is the staged home for Figma-specific SceneGraph conversion policy. Production SceneGraph read/write remains available through @open-pencil/core/io while conversion modules move behind this package's public API.

Current ownership:

Complete .fig archive parsing through parseFigBuffer()
.fig archive assembly through writeFigArchive()
Canvas payload and image resource handling
readFigContainer() / writeFigContainer() helpers for raw fig-kiwi payloads
.fig source and archive result types
NodeChange-to-SceneGraph property conversion, including styles, plugin metadata, text, paint, vector, and font policy, through @open-pencil/fig/node-change
Component-property, symbol-override, derived-symbol-data, and instance synchronization policy through @open-pencil/fig/instance-overrides
Effective raw-metadata precedence and invalidation over SceneGraph's format-neutral edited-field tracking
SceneGraph-to-NodeChange export conversion with an explicit glyph-outline runtime service
Package-local archive, conversion, instance, export, and dist smoke tests

Architecture documentation

Start with the package docs for the source model, instance evaluation, materialization, document sessions, export, and validation contracts.

Planned ownership:

Oracle-backed .fig fixtures

Non-goals:

Generic Kiwi schema/runtime internals — use @open-pencil/kiwi
Format-neutral IO registration, export targeting, CanvasKit thumbnails, or browser workers — use @open-pencil/core/io
Editor actions, renderer behavior, Vue/app UI, CLI formatting, or MCP transport

This follows the existing @open-pencil/pen pattern: a format package owns its source model/parser and SceneGraph policy, while core registers it in the shared IO system.
