Danila Poyarkov d2e380ea9d fix(core): draw gradient and image strokes as the paint they are (#868 ) * fix(core): draw gradient and image strokes as the paint they are A stroke carried the paint vocabulary already, but nothing read it: the .fig reader sent every stroke paint through resolvedPaintColor, which returns black for a gradient or image, the renderer set a flat color on strokePaint, and the writer emitted a SOLID paint. Strokes now go through the same conversion fills do in both directions, and applyGradientFill and applyImageFill take the target Paint so a stroke reuses the fill shader path instead of growing a second one. forVisibleStrokes is the single place every stroke draw passes through, so the shader is set and cleared there rather than threaded through each draw helper. Closes #797 for rendering and .fig; authoring a gradient stroke from the stroke panel is still to come. * feat(app): author gradient and image strokes from the stroke panel StrokeSection opened a solid-only colour picker and synthesised a fake fill for the swatch, so a stroke could never be anything but one flat colour. It now opens FillPicker like the fill panel does, and applyStrokePaint keeps the stroke's weight, align, cap, join and dashes across a paint change. Completes #797. * fix(core): let a gradient stroke reach vector outlines and arrowheads A vector stroke draws its outline as a filled shape with fillPaint, a dashed one strokes the path, and arrowheads are filled shapes of their own; each cleared the shader first, so a gradient or image stroke on a vector drew black. The stroke pass now configures both paints and owns clearing them, and those helpers keep what it set. Resolve each gradient stop against the stroke's own colour binding rather than the stop's position, which looked up another stroke's. Reported in review of #868. * fix(core): release the shaders a paint no longer owns Every gradient and image shader was handed to a paint and then leaked: the paint takes its own reference, so the caller's handle has to go or WASM memory grows with each redraw. Only the diamond branch did this. A gradient stroke now configures two paints, which doubled the leak. Reported in review of #868. * test(render): model a shader handle the caller deletes The pattern shader double returned a plain string, so deleting the handle the paint no longer owns threw instead of passing.		2026-10-04 13:25:45 +00:00

README.md

@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.
