87-209: Removebuilder.arc_to()calls—this method does not exist onPathBuilderin skia-safe 0.91.0.The migration to
PathBuilderis incomplete. Whilemove_to,line_to, andcubic_toexist onPathBuilder,arc_tois only available on the mutablePathtype in skia-safe 0.91.0. Lines 126, 154, 177, and 199 usebuilder.arc_to(), which will fail to compile.Revert this function to use mutable
Path::new()or refactor the arc drawing to use an alternative approach compatible withPathBuilder(e.g., tessellating the arc into cubic Bézier curves).crates/grida-canvas/examples/golden_boolop.rs (1)
73-82: Golden output directory creation is inconsistent with the write target path.
create_dir_all("goldens")depends on CWD, but the write usesCARGO_MANIFEST_DIR/goldens/...; this can fail when run from workspace root.- std::fs::create_dir_all("goldens").unwrap(); - std::fs::write( - concat!(env!("CARGO_MANIFEST_DIR"), "/goldens/boolop.png"), - data.as_bytes(), - ) - .unwrap(); + let goldens_dir = std::path::Path::new(env!("CARGO_MANIFEST_DIR")).join("goldens"); + std::fs::create_dir_all(&goldens_dir).unwrap(); + std::fs::write(goldens_dir.join("boolop.png"), data.as_bytes()).unwrap();crates/grida-canvas/examples/golden_sk_text_backdrop_blur_path.rs (2)
160-167: Embedded font is not registered with theFontCollection—useTypefaceFontProviderinstead.The created
Typefaceis stored but never registered. To make the embedded Geist font available to text layout, create aTypefaceFontProvider, callregister_typeface()with the created typeface, and attach that provider to theFontCollection. The current pattern of setting a default font manager without explicit typeface registration will not resolve the font family name, especially in WASM where system fonts are unavailable.let provider = TypefaceFontProvider::new(); let typeface = font_mgr .new_from_data(&Data::new_copy(cg::fonts::embedded::geist::BYTES), None) .expect("Failed to create typeface"); provider.register_typeface(&typeface); font_collection.set_asset_font_manager(Some(provider));
180-216: Fix non-existent API calls and mutable reference requirements inparagraph_to_pathfunction.The code contains critical compilation errors that go beyond API semantic concerns:
Line 200:
builder.add_path_with_transform()does not exist in skia-safe 0.91.0. The correct API isPath::add_path_matrix(src: &Path, matrix: &Matrix, mode: impl Into<Option<AddPathMode>>). You need to call this on thePathobject, notPathBuilder.Line 213:
path.make_transform(&transform)is called on an immutable reference, but the method signature requires&mut self. The path must be declared as mutable.The double-transform logic (combining glyph positions + origin at line 199, then applying final
(x, y)offset at line 212) is correct in intent but requires the API fixes above.
🧹 Nitpick comments (10)
crates/grida-canvas/examples/golden_sk_paragraph_path_vector.rs (1)
509-516: Tighten readability (and avoid a long single line) around per-glyph transforms.
This is fine functionally, but splitting the matrix creation improves clarity and makes it easier to tweak later (e.g., if you need additional transforms).if let Some(glyph_path) = font.get_path(*glyph) { let offset = Point::new( pos.x + run_origin.x + origin.x, pos.y + run_origin.y + origin.y, ); - builder.add_path_with_transform(&glyph_path, &Matrix::translate((offset.x, offset.y)), None); + let m = Matrix::translate((offset.x, offset.y)); + builder.add_path_with_transform(&glyph_path, &m, None); }crates/grida-canvas/src/shape/ellipse_ring.rs (1)
13-35: Make outer oval direction explicit + validateinner_radius_ratioTo avoid relying on library defaults (and to match the “clockwise” comment), I’d suggest being explicit about winding, and optionally clamping or asserting the documented range:
pub fn build_ring_path(shape: &EllipticalRingShape) -> skia_safe::Path { let mut builder = skia_safe::PathBuilder::new(); + debug_assert!((0.0..=1.0).contains(&shape.inner_radius_ratio)); // ... - builder.add_oval(outer_rect, None, None); + builder.add_oval(outer_rect, Some(skia_safe::PathDirection::CW), Some(0));crates/grida-canvas/src/shape/ellipse_ring_sector.rs (1)
61-98: Builder conversion seems faithful; please sanity-checkarc_tosemantics with negative sweepThe migration reads correct (move_to → arc_to → inner path → close → detach), but because correctness hinges on Skia’s
arc_tobehavior—especially-sweep_degfor the inner arc—I’d recommend confirming output parity (CW/CCW & hole fill) with a quick render/golden test for a few angles (e.g., 90°, 270°, negative sweep).Also applies to: 109-170, 181-269
crates/grida-canvas/src/painter/text_stroke.rs (1)
27-42: VerifyPathBuilder::add_pathAPI/semantics; consider avoiding per-glyphmake_transformif builder supports transformsMain thing to verify is that
builder.add_path(&path)is the intended 0.91.0 API and preserves the previous “append” behavior (previously you hadAddPathModein play). If PathBuilder supports adding with an offset/matrix directly, that’d likely be preferable to allocating a transformedPathper glyph.crates/grida-canvas/src/shape/stroke_rect.rs (2)
263-277: Solid-stroke ring creation via builder-detach is OK; consider de-duplicating the rrect→path boilerplate.A small local helper like
fn path_from_rrect(rr: RRect) -> Pathwould remove repeated builder setup and reduce churn in future edits.
356-373: Clipping ring paths rebuilt via PathBuilder is correct; same de-duplication suggestion applies here.crates/grida-canvas/src/svg/from_usvg_tree.rs (1)
220-228: Immutability change is good; avoid shadowingpathfor readability.Consider:
- let path = path.make_offset((-bounds.x, -bounds.y)); - let data = path.to_svg(); + let offset_path = path.make_offset((-bounds.x, -bounds.y)); + let data = offset_path.to_svg();crates/grida-canvas/src/painter/painter.rs (2)
284-306: Backdrop-blur glyph path accumulation looks correct; watch for per-glyph allocation costs.If skia-safe 0.91 exposes an “add path with matrix/offset” API on
PathBuilder, consider using it to avoidglyph_path.make_transform(...)per glyph.
956-974: Mask-path recursion works, butdetach()/new_path()in the loop may be costly.If this shows up in profiles, a common pattern is: recurse into a fresh
Path, thenbuilder.add_path(&nested)(instead of rebuilding the builder from a detached path each time).crates/grida-canvas/src/shape/stroke_varwidth.rs (1)
204-207: Optimize path concatenation to avoid repeated builder reconstructions in the segment loop.Each iteration rebuilds a new
PathBuilder(new_path+add_path+detach) when concatenating segment paths. For loops with many segments, consider creating the builder once on the second segment and appending all remaining paths before a single finaldetach()to avoid repeated path structure copying.The suggested diff (keeping the first segment as
Path, then building once) is a reasonable minimal-churn approach. If feasible, a persistent builder across all iterations would eliminate repeated reconstructions entirely.

crates/grida-canvas/examples/golden_sk_svg_filters/main.rs (1)
1975-1996: LGTM! Clean migration to PathBuilder pattern.The refactor correctly adopts the PathBuilder pattern for skia-safe 0.91.0. The implementation properly:
- Initializes the builder
- Maps all TinyPath segments to corresponding builder methods
- Finalizes with
detach()to produce the immutable PathThis aligns with the PR objectives to update path building practices.
Based on learnings, the
skia-safecrate is used for all painting and rendering operations in this codebase.crates/grida-canvas/examples/golden_sk_mask.rs (4)
3-4: LGTM! Import changes support PathBuilder migration.The imports correctly add
PathBuilderfor the new path construction pattern and maintainTileModefor the gradient shaders.
41-48: Excellent PathBuilder pattern usage.The diagonal band path construction correctly adopts the PathBuilder pattern: creating a builder, chaining operations, closing, and detaching to obtain an immutable Path. This is the idiomatic approach for skia-safe 0.91.0.
54-58: Clean circular path construction.Using
Path::circleis the idiomatic way to create circular paths in skia-safe 0.91.0, eliminating the need for manual path building for simple geometric shapes.
69-73: Consistent circular path construction for outline.The outline path correctly uses the same
Path::circlepattern and geometry as the clip path, ensuring visual consistency between the clipped region and its outline.crates/grida-canvas/examples/golden_sk_paints.rs (1)
368-376: No action needed—code is correct as-is.
Path::rect(rect, None)is the idiomatic pattern throughout the codebase (used consistently in geometry.rs, shape/rect.rs, and other examples). The recent commit "update examples path building" confirms this is an intentional alignment with production code. No behavior drift or winding/direction concerns exist.crates/grida-canvas/src/shape/rrect.rs (1)
38-40: LGTM! Simplified path construction aligns with the migration pattern.The direct use of
Path::rrect()is more concise and idiomatic than the previous mutable approach. The API is supported in skia-safe 0.91.0 with the signaturepub fn rrect(rect: impl AsRef<RRect>, dir: impl Into<Option<PathDirection>>) -> Self, and your usage withNonefor the optional direction parameter is correct.crates/grida-canvas/examples/golden_sk_paragraph_path_vector.rs (1)
501-525: No API correctness issues found — this code correctly implements the expected skia-safe 0.91.0 semantics.The
Paragraph::visitcallback signatureFnMut(usize, Option<&'a VisitorInfo>)matches the usage in the code (|_, run|). TheNoneparameter inadd_path_with_transformmeans "no additional transform" (identity), which is correct—the offset positioning is already applied viaMatrix::translatebefore theNoneis passed, so no winding or path behavior is affected. The implementation is idiomatic and sound.Likely an incorrect or invalid review comment.
crates/grida-canvas/src/shape/polygon.rs (1)
15-18: No changes required.build_path_from_pointsrelies onPath::polygon, which safely handles all point counts (0, 1, 2, and 3+ points) without panicking or exhibiting undefined behavior. All in-tree callers already enforce the n >= 3 precondition through assertions inbuild_simple_polygon_pathandbuild_simple_polygon_vector_network. No external callers exist in the codebase, eliminating the theoretical risk of unvalidated input from public consumers.crates/grida-canvas/src/devtools/ruler_overlay.rs (3)
3-3: LGTM! PathBuilder import added for 0.91.0 migration.The import correctly adds
PathBuilderto support the new path construction pattern.
94-94: Correct path finalization.Using
builder.detach()correctly finalizes the PathBuilder and produces the immutablePathfor caching and rendering.
67-89: PathBuilder pattern correctly applied.The migration from direct Path construction to PathBuilder follows the correct pattern: create builder, accumulate path operations via
move_to/line_to, then finalize withdetach(). The logic for constructing vertical and horizontal grid lines is preserved.Since this is a major version upgrade (0.89.0 → 0.91.0), verify that the PathBuilder API usage aligns with the skia-safe 0.91.0 documentation:
skia-safe 0.91.0 PathBuilder API documentationcrates/grida-canvas/src/painter/layer.rs (1)
1073-1076: The original concern aboutPath::make_transformreturningOption<Path>in skia-safe 0.91.0 is unfounded. The method signature ispub fn make_transform(&mut self, m: &Matrix, pc: impl Into<Option<ApplyPerspectiveClip>>) -> Path, returning an ownedPathvalue directly. The code at lines 1075 and 1092 correctly assigns the return value without optional handling. No changes needed.crates/grida-canvas/src/shape/ellipse_sector.rs (1)
1-48: PathBuilder migration is correct;arc_tosignature verified.The
arc_to(oval, start_angle, sweep_angle, force_move_to)call is properly implemented:
outer_rectcorrectly bounds the ellipsestart_degandsweep_deguse standard Skia angles (0° = +X axis, positive = clockwise)force_move_to=falseis the right choice since the path is non-empty (aftermove_toandline_toto the start point); this appends a line connecting the current point to the arc start, which is the intended behavior for a sectorNo changes needed.
crates/grida-canvas/examples/golden_path_discrete.rs (1)
5-5: Good simplification;Path::circle(..., None)correctly uses the default winding direction.The third parameter accepts
PathDirection(CW or CCW) to control the circle's winding direction. PassingNoneapplies the default behavior, preserving the expected semantics from any prior implementation.crates/grida-canvas/src/shape/ellipse.rs (1)
8-13: None for the direction parameter is correct and uses Skia's default clockwise direction.In skia-safe 0.91.0,
Path::oval(rect, dir)accepts an optionalPathDirectionas the second argument. PassingNonemeans the underlying Skia default (kCW / clockwise) is used. This preserves correct ellipse geometry and is an appropriate simplification.crates/grida-canvas/src/shape/rect.rs (1)
18-20:Path::rect(&rect, None)is correct for this conversion trait. It constructs a new Path from the rectangle using the appropriate defaults (clockwise direction, starting at upper-left). Since the trait implementation needs to return a new Path rather than mutate an existing one,Path::rect()(constructor) is the right choice, notadd_rect()(appender).crates/grida-canvas/src/devtools/text_overlay.rs (1)
32-41: PathBuilder baseline construction looks correctBuilder-based baseline segments should behave the same as the previous Path mutation pattern, and returning
Some(builder.detach())is consistent with the rest of the migration.crates/grida-canvas/src/devtools/hit_overlay.rs (1)
88-90: Transform order preserved; confirmmake_transformfailure semanticsThe sequential reassignment matches the old “apply layer, then apply camera” order. Only concern is whether
make_transformcan fail/produce empty paths in cases where the oldtransformmutated in-place—worth confirming via build + a quick devtools smoke test.crates/grida-canvas/src/sk_tiny/mod.rs (1)
8-30: TinyPath → SkPath conversion via PathBuilder looks correctThe segment mapping is direct and should preserve contour boundaries and closes.
crates/grida-canvas/src/painter/geometry.rs (1)
121-134: LGTM on direct constructors; double-checkNode::Lineintent + Skia API signatures
to_path()simplification reads clean and should reduce unnecessary path mutation.Path::line((0,0),(width,0))is fine if “Line” is defined as a horizontal segment in local space (with transforms handling rotation); just confirm thatn.size.heightis not meant to participate here.Also applies to: 163-164, 334-335
crates/grida-canvas/examples/golden_boolop.rs (3)
1-1: Import addition is fine; keep skia-safe path construction consistent across examples.This aligns with the broader PathBuilder migration (and matches the “use skia-safe for rendering” guideline). As per coding guidelines, use
skia-safefor painting/rendering operations.
15-16: Constructor-basedPath::rect/Path::circleusage looks correct.Nice simplification vs mutable path building; should reduce accidental mutation and match skia-safe 0.91+ patterns.
Also applies to: 27-28, 50-51, 59-60
36-42: Removeunwrap()onPath::opat line 61; the method can legitimately returnNone.Line 61 uses
.unwrap()on aPath::opcall that can fail. Since this is an example/test file that runs in CI, it should handle the failure gracefully rather than panic:- let union = Path::op(&r, &c, PathOp::Union).unwrap(); + let Some(union) = Path::op(&r, &c, PathOp::Union) else { + return; + };All other
Path::opcalls in this file (lines 17, 29, 43, 52, 68) are already correctly usingif let Some(...)pattern matching.Likely an incorrect or invalid review comment.
crates/grida-canvas/src/shape/stroke_rect.rs (1)
3-4: Import update is fine for the PathBuilder migration.crates/grida-canvas/src/painter/painter.rs (2)
16-19: Import extension for PathBuilder is fine.
976-982: Layer transform viamake_transformis the right direction (immutable transform).Looks consistent with the broader migration away from in-place mutation.
crates/grida-canvas/src/vectornetwork/vn.rs (3)
271-315: Builder-based segment-to-path conversion looks correct.Returning
builder.detach()for empty segments is a clean way to produce an emptyPath.
362-409: Region path construction +set_fill_typebeforedetach()is good.Optional hardening: if loops are supposed to always close, consider a final
builder.close()when a loop finishes but didn’t return to its start (to avoid surprising fill artifacts from malformed data).
417-423: Appending paths via a single builder is clean and consistent with the migration.crates/grida-canvas/src/text/mod.rs (3)
5-5: LGTM: Updated imports for PathBuilder migration.The imports correctly add
MatrixandPathBuilderto support the new path construction pattern.
34-37: LGTM: Clean API addition for vector network conversion.The new
paragraph_to_vector_networkfunction provides a convenient public API for converting paragraphs directly to vector networks. The implementation correctly delegates toparagraph_to_pathand leverages the existingVectorNetwork::fromconversion.
8-31: LGTM: PathBuilder migration is clean and includes zero-offset optimization.The refactored path construction correctly uses the builder pattern and adds an optimization to skip identity transforms when the glyph offset is zero. The conditional transform logic (lines 19-25) is a good performance enhancement. All APIs (PathBuilder, add_path, make_transform, detach) are properly available in skia-safe 0.91.0 and are correctly applied here.
crates/grida-canvas/tests/stroke_dash_width.rs (1)
5-18: LGTM: Test helper functions updated to PathBuilder pattern.Both helper functions correctly adopt the PathBuilder pattern for path construction. The changes are mechanical and preserve the original test behavior.
crates/grida-canvas/src/hittest/hit_tester.rs (1)

skia-safe 0.91.0 PathBuilder snapshot detach migration path mutation removal
💡 Result:
Short answer: In skia-safe 0.91.0 snapshot/detach are methods on Path (Path::snapshot(), Path::detach()) — not on PathBuilder — so migration is to finish building your path and call snapshot() / detach() on the Path you built (or use Path::raw / Path::new helpers). See the 0.91.0 docs showing Path::snapshot() and Path::detach(). [1][2]
If you have code that previously called snapshot/detach on a PathBuilder, change it to:
- obtain the built Path (e.g. let path = path_builder.finish(); or otherwise get the Path),
- then call path.snapshot() (returns a copy) or path.detach() (returns a copy and clears the original) as needed.
References:
- skia-safe Path documentation (shows snapshot & detach in 0.91.0). [1]
- skia-safe crate listing / 0.91.0 release docs. [2]
If you want, paste the snippet you need migrated and I’ll convert it.
Critical: skia-safe 0.91.0 removes Path::make_transform() – extensive codebase usage requires migration.
The upgrade to 0.91.0 introduces a breaking change: path mutation functions (including make_transform()) have been removed. The codebase has 15+ active uses of path.make_transform() across painter, text, hittest, and devtools modules that will fail to compile.
Migration: Instead of path.make_transform(&matrix), use PathBuilder to construct a new path with transformations applied, or build paths without mutation. Example pattern currently in ellipse_ring.rs shows the correct approach: use PathBuilder with add_oval() and detach().
Additionally, the package edition remains "2021" while repo guidelines recommend "2024" for graphics core—consider addressing in this PR or follow-up.

code that constructs a new transformed Path via PathBuilder (or other
non-mutating API) — e.g., create a PathBuilder, add the original geometry (or
use the same builder pattern used in ellipse_ring.rs: add_oval()/other add_*
calls), apply the matrix transformation while building, then call detach() to
get the new Path; update all call sites accordingly to stop relying on path
mutation. Also consider updating the package edition from "2021" to "2024" in

Golden determinism + WASM parity risk: relies on system fonts (FontMgr::new() / “Arial”).
Since this file is used to generate a golden PNG, system-font selection can differ across machines/CI and diverge even more on WASM (per the PR note). Consider making all text (title/labels too) use fixture fonts (same TypefaceFontProvider/FontCollection approach you use elsewhere) so the output is deterministic. Based on learnings, skia-safe should be the backend, but the font source should be controlled.

17 to 26, the example currently relies on system fonts (FontMgr::new()/“Arial”)
which breaks golden determinism and WASM parity; replace system font usage by
loading the fixture font(s) into a TypefaceFontProvider, attach that provider to
a FontCollection, and use that FontCollection for all Paragraph/ParagraphBuilder
TextStyles (title and labels included). Ensure you load the bundled font data
(e.g., via include_bytes! or the project fixture loader), register it with the
TypefaceFontProvider, set the default typeface in ParagraphStyle/TextStyle where
needed, and remove any calls to FontMgr::new() or hardcoded family names so the
generated PNG is deterministic across machines and WASM.

Compose the two transform matrices into a single matrix, then apply one make_transform call to reduce path allocations.
The return type of make_transform is Path (not Option), so the code compiles. However, applying two sequential transforms creates two path allocations. Pre-compose transform.matrix with camera.view_matrix().matrix using AffineTransform::compose() (or equivalent matrix composition), then call make_transform once. This pattern is already used elsewhere in the codebase (e.g., painter/geometry.rs, painter/layer.rs).

continue_path=true likely needs an explicit join to pts[0] (otherwise first cubic starts from the wrong point).
When continuing, the current point is whatever the previous sub-path ended at, but the Catmull control math for the first segment is based on p1 = pts[0]. Without moving/connecting to pts[0], the first cubic_to will start at the wrong anchor and can distort the outline join.
Suggested fix:
fn add_catmull_segments(builder: &mut PathBuilder, pts: &[(f32, f32)], continue_path: bool) {
if pts.is_empty() {
return;
}
