Closes #1763 (part 2 of 2: dashed lines and outlines; part 1, rotated text, is #1799). The two PRs are independent: each branches from main and touches different fields, so either can go first.

A layout line had a colour, width, direction and heads, and a rectangle or ellipse only a solid outline. So the page couldn't show a dashed leader line, a dashed box marking a study area or an inset's extent, or a dotted neatline, though map layers already dash their strokes. This PR adds dash to Line and to the outline of Rectangle and Ellipse, reusing symbology::Dash, as the issue proposes.

Left: what main can draw, a study area box and its leader solid. Right: the same elements with "dash": [4, 2] on the rectangle and [3, 2] on the arrow, whose head stays solid. A crop of an A4 layout.publication of the sample World Atlas, exported to PNG at 150 dpi with rustgis-cli run built from this branch; the left one is the same layout without dash, which draws as main does. The SVG and PDF exports of the right one draw the same dashes (checked by rendering the PDF with PyMuPDF).

The dashed rectangle selected in the layout view (ui_shot), its Format pane showing the new Dash list open: the Symbology pane's presets. It shows 4 2 because the pattern was set by command and isn't a preset at this width (below).

What changes

1. dash: Option<Dash> on ElementKind::Line, Rectangle and Ellipse, the same type a line layer's stroke has: lengths in points, dash and gap in turn (an odd count repeats, as SVG's), at most MAX_DASH_STEPS steps of up to MAX_DASH_STEP. It is written only when there is one (skip_serializing_if = "Option::is_none"), so layouts saved before keep their bytes, and read with the same lenient de_dash as a layer (now pub(crate)): a hand-edited pattern is brought into range, and one left with no length reads as solid.
2. Commands. layout.addElement (line, arrow, rectangle, ellipse, circle) and layout.update take "dash": [4, 2], read as layer.lineStrokes reads a stroke's. [] or null makes it solid. A value that isn't a pattern (a string, a non-number, a negative or 0-only list, more than 8 steps, a step over 500) is refused with dash is a list of 1 to 8 lengths in points (dash, gap, …), each 0 to 500, not all 0; [] or null for solid, and nothing changes; dash given for another kind of element is refused (only lines, arrows, rectangles, ellipses and circles take a dash), as radius is. An update that doesn't give dash keeps it.
3. Every output draws it.
   • Canvas, PNG and the other raster exports: the stroke gets a tiny_skia::StrokeDash, through dash_steps, which is the old Ctx::dash of the map renderer pulled out into a function: a pattern under a pixel a round, or one that would cut the path into more than MAX_DASHES pieces, is drawn solid, as a layer's is.
   • Vector PDF and GeoPDF: the recording canvas keeps the dashes as the pieces tiny-skia cuts, as it already does for a dashed map layer (Canvas::stroke_path; vector::Stroke is solid by design), so the PDF draws the same dashes as the picture.
   • SVG: stroke-dasharray, in the page's millimetres as stroke-width is.
4. Only the shaft is dashed. An arrow's heads are filled triangles, so they stay solid.
5. Format pane: a Dash list under a line's Width and under a rectangle's or ellipse's Outline width, with the Symbology pane's presets (DASH_PRESETS, now pub(crate): Solid, Dashed, Dotted, Dash-dot, Long dash), scaled by the width as that pane scales them. A pattern set by command that isn't a preset at that width shows as its lengths.
6. A locked element: "dash": null counts as a change, so it is refused on a locked element like any other change (before, a null value was never a change).
7. User guide: docs/user-guide/layouts.md describes Dash under Shapes.

Choices

• No new dash type (the issue's choice): a layout and a layer mean the same thing by a pattern, with the same limits and the same lenient read.
• The PDF keeps dashes as pieces, not as a d dash array. The issue proposed a PDF dash array. The vector drawing the PDF is written from keeps strokes solid by design and cuts a dashed stroke into its dashes, which is how a dashed map layer reaches the PDF today. Writing a dash operator would change vector::Stroke, the replay and the content stream for map layers too, so it seemed better as its own change, for both at once, if wanted. The test checks that the PDF's drawing holds the dashes and draws what the PNG shows.
• Presets scaled by width, as in the Symbology pane, so a thick line's dashes stay in proportion; a pattern given by command is kept as given.
• Units: the steps are in the layout's points, the unit of a line's width (PT_PER_MM), so [4, 2] on a 1-point line looks as it does on a layer's 1-point stroke.

Tests

• dashes_round_trip_and_old_layouts_keep_their_bytes (map): a line, rectangle and ellipse with a pattern round-trip; solid ones write no dash and a layout without one is written back byte for byte; read from a file, [4, 1e9, -2] becomes [4, 500, 0] and [0, 0] solid.
• dashed_lines_and_outlines_have_gaps (render): along a dashed arrow's shaft, the gaps its pattern gives (some 22 over 69 mm of a 6-6 pattern), none across its head and none when solid; a dashed rectangle has gaps on all four sides; round a dashed ellipse, gaps all along, none when solid.
• a_dashed_outline_is_kept_as_its_dashes (render): the recorded page keeps the outline as many dash pieces, and replaying them draws what the PNG shows.
• dashes_are_written_as_a_dasharray (render, SVG): stroke-dasharray="1.058 0.529" on the line, rectangle and ellipse for [4, 2], none on the arrowhead, none when solid.
• lines_and_outlines_take_a_dash (engine): dash on layout.addElement for an arrow, rectangle and circle; kept through a save; changed, kept by an update without it, made solid with [] and null; the refusals above for add and update, with nothing changed; refused on a text and a north arrow; null refused on a locked arrow.
• the_format_pane_dashes_an_outline (ui-egui, kittest): picking Dashed in a 2-point rectangle's Dash list sets [8, 4]; Solid clears it.

cargo fmt --check and cargo clippy --workspace --all-targets -- -D warnings pass locally (Windows). The library tests of rustgis-map (283), rustgis-render (397) and rustgis-ui-egui (816) pass; those of rustgis-engine (1277) pass except gdal_formats_open_when_gdal_is_installed, which needs GDAL 3.8 and this PC has an older one, and one archive_render_revision test that failed in the full parallel run and passes when its module runs alone. The rustgis-ui-egui integration tests weren't run here (the disk was short of room for their binaries); CI runs them.

Size

About 450 added lines: some 200 of code, 220 of tests, the guide paragraph, and dash: None where existing code builds lines and rectangles (publication sheets, presentations, tests). That is a little past the 300–400 lines aimed for, mostly tests.

Limits

• No new interface strings: Dash and the preset names are already in the catalogs, so no i18n/*.tsv change.
• No format version change, as with the other optional layout fields (radius, letter_spacing, the legend's columns): an older RustGIS opening a layout with a dashed element draws it solid, and drops the pattern if it saves the file again. No map data is lost.
• The pattern starts where the outline's path starts (a rectangle's top-left corner), so corners aren't adjusted to fall on a dash, as a layer's polygon outline isn't.

Walkthrough

Layout elements now support optional dash patterns on line shafts and rectangle, ellipse, and circle outlines. Layout commands and the Format pane can set these patterns. Raster and SVG rendering apply them, while arrowheads remain solid.

Changes: Layout dashed strokes

Layer / File(s)	Summary
Dash data and serialization crates/map/src/layout.rs, crates/map/src/symbology.rs	Rectangle, ellipse, and line elements store optional dash patterns. Absent patterns are omitted during serialization, and loaded patterns use the shared dash deserializer.
Create and update dash patterns crates/engine/src/cmd/layout.rs, crates/engine/src/cmd/presentation.rs, crates/engine/src/tests.rs	layout.addElement and layout.update parse dash patterns for supported element kinds. Omitted update values preserve the current pattern; [] and null specify solid strokes. Tests cover validation, unsupported kinds, persistence, and locked elements.
Format pane dash picker crates/ui-egui/src/layoutview.rs, crates/ui-egui/src/panes.rs	The Format pane provides dash presets for rectangle, ellipse, and line elements. Preset steps scale with stroke width; the Solid option sends an empty pattern.
Raster and SVG rendering crates/render/src/layout.rs, crates/render/src/lib.rs, crates/render/src/svg.rs, docs/user-guide/layouts.md	Raster and SVG output render dashed outlines and line shafts. Arrowheads remain solid. Tests cover rendered gaps, vector recording, and SVG stroke-dasharray; the layout guide describes the setting and its limits.

Full details: Title check

Explanation

The title "feat(layout): dashed lines and outlines (#1763, part 2)" names the main change: dash patterns for layout lines, arrows, rectangles, ellipses and circles. The raw summary and objectives confirm this. The issue number and part number are extra context, but the title is accurate and specific.

Full details: Description check

Explanation

The description follows the repository template. It has a Summary that explains the change and why it is needed. It has a Testing section that lists the new tests and the local checks, with the exceptions stated. It has a UI evidence section with before and after screenshots, which the template requires for visible UI changes. It links the related issue (#1763) and the companion PR (#1799). The Related issue heading is kept, and its text is filled in as "Closes #1763".

Full details: Out of Scope Changes check

Explanation

All changes at this head connect to the dashed-strokes requirement of #1763. The model field, serialization and de_dash reuse are in crates/map. The render changes and the dashed and dash_steps helpers are in crates/render. The SVG stroke-dasharray output is in crates/render/src/svg.rs. The commands, the locked-element check, the Format pane, the DASH_PRESETS visibility and the user-guide paragraph expose the same feature. The dash: None edits in presentation and test code only add the new field to existing struct literals. No unrelated behaviour change was found in the summarized changes. Rotation is not in the diff, so it cannot be out of scope here.

Full details: Linked Issues check

Explanation

Issue #1763 has two coding requirements: rotated text and dashed lines and outlines. The dashed requirement is implemented at head 474291f. ElementKind::Line, Rectangle and Ellipse gain dash: Option<Dash> in crates/map/src/layout.rs. draw_page in crates/render/src/layout.rs applies the pattern through dashed and dash_steps, and arrowheads stay solid. The engine commands in crates/engine/src/cmd/layout.rs validate and store dash. The SVG writer and the Format pane also handle it. The incremental changes since the previous review (the dash: null lock check, the de_dash visibility change and the user-guide paragraph) do not add rotation. The rotated-text requirement is absent at this head: no rotation on ElementKind::Text, no render, SVG or PDF handling, no command parameter and no Format pane field. The PR description places rotation in #1799, which is not part of this head. The PR still states that it closes #1763, so merging it alone would close an issue with an unmet requirement.

Resolution

Either (a) implement the rotated-text requirement of #1763 in this PR: rotation on text elements, written only when non-zero, drawn in canvas, PNG, PDF/GeoPDF and SVG, accepted by layout.addElement and layout.update, with a Format pane field; or (b) change the link so this PR does not close #1763 (for example, reference it as partial) and keep #1763 open until #1799 merges and covers rotation.

Its dashed trail skips in neat design.

While arrowheads stay bold for him.
Solid strokes return on cue,

[github-actions]

Never silent (AGENTS.md), confidence medium. This lenient read now also runs for layout elements. It drops steps past MAX_DASH_STEPS with take, clamps values above 500 and turns NaN into 0, and a pattern left all zero silently becomes solid. A hand-edited layout therefore draws differently with no notice, and nothing tells the user the pattern was changed. The layer reader already behaves this way, so this is not new for layers, but the PR adds a new path to it. Please report it through the load path (Session::notify, with a count), or say why this path is exempt.

[elpidioassinaturas]

Not changing this here. This is the reader a line layer's pattern already goes through, by the issue's choice that a layout and a layer read a pattern the same way; only a hand-edited file reaches the cases it repairs (more than 8 steps, a step over 500, NaN or all zero), since the commands refuse them with a message. Reporting them would need de_dash to count what it repairs where Layout::clamp (and the layer's load) can see it, for both paths at once; that seems better as its own change than as a layout-only notice here. Leaving this open in case a maintainer wants it in this PR.

🤖 Addressed by Claude Code

[github-actions]

Claude autofix (unclear): Not changed here. You're right that the lenient read is silent: steps past MAX_DASH_STEPS are dropped, values are clamped, and NaN becomes 0. It isn't exempt. The fix needs a design choice: de_dash is a serde deserializer with no Session, and layout clamp() only sees the already-clamped Dash, so the repair can't be counted there. Options are to keep the raw steps until the repair pass or to add a counted reader. The layer reader has the same gap. Leaving this for a maintainer to decide.

Code review

Reviewed the dash support for layout lines, rectangles and ellipses against the base branch. The core logic holds up on reading: the pattern is validated before anything changes, the renderer and SVG paths agree on units, and the arrowhead stays solid. The three concerns below were posted inline. There are no prior review threads, so none were skipped as already raised.

Bugs

• None confirmed.

Security

• None found. The new dash input is validated in element_dash, and the file read is bounded by Dash::new.

Performance

• crates/render/src/lib.rs:842: MAX_DASHES caps each stroke, not the page. Many dashed outlines in one layout could each produce up to 100k vector pieces. Confidence low (~30%).

Quality

• crates/map/src/symbology.rs:323: the lenient read now also applies to layouts. It silently truncates to 8 steps, clamps values, and turns an all-zero pattern solid. Confidence medium.

AGENTS.md

• Never silent: the same silent read as above, which the rules forbid. Confidence medium.
• crates/engine/src/cmd/layout.rs:3641 (and about line 2733 in addElement): "dash": null on a text, north arrow or map frame succeeds as a silent no-op. This contradicts the "refused for other kinds" wording. Confidence medium-high. The suggested fix changes behaviour for clients that send null for every key, which is a judgment call.
• Everything else I checked follows the file: no new unwrap/panic in non-test code, tl! on the new label, no wasm-breaking std time, and the optional-field format rule is met.

I did not run the test suite, since this review is read-only and I had no shell. The author reports the crate tests passing locally.

AGENTS.md saved-files rule, confidence ~75%. An older RustGIS reads this layout, draws the element solid, and on its next save writes the layout without dash. That is the case docs/maintaining.md#saved-files-and-settings forbids: "An older RustGIS ... doesn't save it again without what it couldn't read." The Limits section of the PR says so openly, and the precedent of radius, letter_spacing and columns doesn't exempt a new field. Layouts carry no format version, so an older reader has nothing to detect a newer file by. The fix is a maintainer call: a project format version bump (the rule says it goes up "when a file uses something an older reader would lose"), or a note in the PR that a maintainer accepted this loss. Confirm with a maintainer rather than treating it as settled.

[elpidioassinaturas]

No change here: this is the same question as the format version on #1799 (#1799 (comment)) and #1796, and it is the maintainer's call. The answer there applies to dash too: optional layout fields (radius, letter_spacing, the legend's columns) were added this way, .rgislayout files have no version to raise, and raising the project's FORMAT would make 0.6.0 refuse every project this writes. If a maintainer wants a version change, I'll make it in both PRs. Leaving this open for that view.

🤖 Addressed by Claude Code

[github-actions]

Claude autofix (unclear): Not changed here. Agreed that an older RustGIS would draw a dashed element solid and drop dash on its next save. That is a visible result change, so it isn't the 'costs a setting' case in docs/maintaining.md. The options are a project format version bump (needs two maintainers, per the saved-files section) or a maintainer accepting the loss and saying so in the PR. Waiting for that decision.

[github-actions]

Code review

Bugs: None found. I checked the new element_dash parsing, the add_element/update refusals, the restyle paths, the locked-element check, and the render helper dashed/dash_steps. The Format pane's preset scaling tops out at 8 × 50 = 400 points, under the 500 limit. I found no construction site outside the changed files that misses the new dash field.

Security: None found. Pattern input is bounded by Dash::new (at most 8 steps, each 0 to 500, finite), and the JSON values are clamped before conversion.

Performance: Nothing new beyond the per-stroke MAX_DASHES cap. The prior thread's concern about a page-wide piece budget was answered (vector::MAX_COST), so I left it alone.

Quality:

• SVG output doesn't apply the raster guard that draws tiny patterns solid, so output differs by format. Low confidence, about 40%. Inline comment on crates/render/src/svg.rs:287.

AGENTS.md:

• An older RustGIS drops dash on re-save, and layouts have no format version to detect it. This conflicts with the saved-files rule in docs/maintaining.md. Confidence about 75%. Inline comment on crates/map/src/layout.rs:1026. The PR's Limits section acknowledges the loss. Precedent from radius doesn't exempt it, so a maintainer should decide between a version bump and an explicit acceptance.

Prior threads: I left 2 earlier concerns alone because they were already answered: the silent de_dash read (symbology.rs:323, answered and deferred by the author) and the page-wide piece budget (render/lib.rs:842, answered). The null refusal thread (layout.rs:3641) was fixed in 38861075, so it is not reposted.

Code review

No new findings at or above 30% confidence, so I'm posting no inline comments. I read the full diff, the base-branch AGENTS.md, and the five existing threads. I could not build or run tests (read-only review), so the conclusions come from reading the code.

Bugs

• None found. I checked the refusal order in layout.update: the dash check runs before any mutation, and the unlock step only checks, so a refused call changes nothing. Every ElementKind::Line, Rectangle and Ellipse construction and pattern in the workspace is updated. Bad dash values (negative, over 500, more than 8 steps, all zero, non-numeric) are refused by Dash::new and element_dash. Confidence: high.

Security

• None found. The new input is bounded by Dash::new, with no unchecked indexing or unwrap in non-test code. Confidence: high.

Performance

• None new. Per-stroke dash pieces are capped by MAX_DASHES, and the page-wide budget is covered by an existing thread. Confidence: medium.

Quality

• Silent solid fallback (confidence about 30%). When dash_steps finds a pattern shorter than a pixel per period, it draws the element solid in PNG and PDF with no notice, while SVG keeps the dashes. A user who asks for [0.2, 0.2] gets a solid line and no warning. The existing SVG thread covers the mismatch but not the silence. Same behaviour as layers, so this is a maintainer call.
• Nit, for the release quality pass: the test helper gaps says it counts "from from to to", but it takes an iterator.

AGENTS.md

• Never silent, reader clamping (open, existing thread, left alone). de_dash silently truncates, clamps and zeroes hand-edited layout patterns. The author has answered and the code is unchanged, so I did not repeat it.
• Saved-files rule (open, existing thread, left alone). An older RustGIS drops dash on its next save, which the Limits section discloses. The format-version question is for a maintainer.
• Otherwise compliant as far as the diff shows: tl! is used for the new labels, docs/user-guide/layouts.md is updated, no new background command or dependency, and no assets added.

Prior threads: of the five existing threads, two are open and I left them alone because the author replied and the code is unchanged. The other three are resolved or outdated and I did not re-raise them. The null refusal fix (commit 3886107) is present in the current code: both layout.addElement and layout.update test for the key.

Code review

Bugs

• Stray > characters break the test targets (3 places), confidence high. Each one replaces a line's first character, so the file no longer parses inside #[cfg(test)]:

  • crates/map/src/layout.rs:2128 (> })
  • crates/render/src/layout.rs:3715 (> let info = PageInfo::default();)
  • crates/render/src/svg.rs:414 (> })

  rustgis-map and rustgis-render tests won't compile, so cargo test and cargo clippy --all-targets fail. The PR description says both pass locally, so the pushed head probably differs from what was tested. Inline comments with suggestion blocks are posted on all three lines.

Security

• None found. The new dash input goes through element_dash → Dash::new, which refuses non-numbers, negatives, NaN/infinity, more than 8 steps, steps over 500 and all-zero patterns. The new paths add no unwrap, expect, or indexing outside tests.

Performance

• None new. dash_steps caps dashes per path at MAX_DASHES before both the raster and vector paths, and the vector path reuses that guard. The SVG path has no equivalent guard. The earlier thread on this was answered with "commands accept no pattern under 0", but Dash::new also accepts tiny positive steps such as 0.01. Confidence low (about 30%). I left the thread alone because the reply covers the design intent.

Quality

• No new points beyond the compile errors above. The layout.update / layout.addElement dash: null refusal was implemented as the earlier thread asked.

AGENTS.md

• Format-version and saved-files concern (crates/map/src/layout.rs ~1031): an older RustGIS draws a dashed element solid and drops dash on save. This is still open with the maintainer and I left it alone.
• Silent lenient read in de_dash (crates/map/src/symbology.rs ~323): still open. The author and reviewer disagree about whether it needs a notice. I left it alone.
• Hostile-input and background-work rules are otherwise followed: the new code adds no long loops, and the UI test covers the Format pane.

I left 4 earlier concerns alone because they were already raised and answered or are awaiting a maintainer decision: the de_dash silent read, the layout format version, the MAX_DASHES per-page budget and the SVG-versus-raster guard difference. The dash: null refusal on other kinds was already fixed in 38861075.

Either (a) implement the rotated-text requirement of #1763 in this PR:
`rotation` on text elements, written only when non-zero, drawn in canvas, PNG,
PDF/GeoPDF and SVG, accepted by `layout.addElement` and `layout.update`, with a
Format pane field; or (b) change the link so this PR does not close #1763 (for
example, reference it as partial) and keep #1763 open until #1799 merges and
covers rotation.

Assert that rejected updates preserve the complete element.

Each invalid update also requests "width": 5, but the test checks only that dash remains unchanged. An implementation that changes the width before rejecting the dash would pass.

Capture the element before each update. After the error, assert that the complete element is unchanged.

Remove the stray > to restore compilation.

The leading > is invalid Rust syntax. It prevents rustgis-map from compiling, including in the supplied docs-preview build. Remove the token.

Remove the stray > before let info in the layout test.

Line 3715 starts with a > token before let info = PageInfo::default();. Rust cannot parse this statement, so the file does not compile. The render crate's test target fails to build.

Remove the stray > before the closing brace of the test.

Line 414 starts with > before the closing }. The preceding statement on line 413 ends with ;, so the > cannot be parsed. This syntax error stops crates/render/src/svg.rs from compiling, which blocks the render crate and any crate that depends on it.
