Part of #1763 (part 1 of 2: rotated text; dashed lines and outlines are #1802). The two PRs are independent: each branches from main, so either can go first.

A layout text element had no angle, so text along the side of a frame wasn't possible: a credit or source line up the margin, vertical grid coordinates, a name at an angle in an inset. This PR adds rotation to the text element, as the issue proposes.

Left: what main can draw, the credit line lying across the bottom margin. Right: the same text element with "rotation": -90, running up the right margin. 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 with the text unturned, which draws as main does.

The turned text selected in the layout view (ui_shot): the dashed box and the handles follow the turned box, and the Format pane's Element section has the new Rotation field with its 0°, 90° and -90° quick picks.

What changes

1. rotation on ElementKind::Text, in degrees clockwise, the convention of a map frame's bearing: 90 reads top to bottom, -90 bottom to top. The text turns about the centre of its box. The element keeps x, y, w, h as the unturned box, so moving, aligning, nudging and the X/Y/Width/Height fields work as before.
2. Saved only when it isn't 0 (skip_serializing_if = "is_zero"), so layouts and projects saved before keep their bytes. A value read from a file is normalized to -180..180 in Layout::clamp (450 is 90, a non-finite one is 0).
3. Commands. layout.addElement (text, dynamicText) and layout.update take "rotation". A finite number is normalized to -180..180; a value that isn't a number is refused (rotation is a number of degrees, clockwise) and changes nothing; "rotation" given for another kind of element is refused (only text elements take a rotation), as radius and font are. null leaves it as it is.
4. Every output draws it.
   • Canvas, PNG and the other raster exports: the text is drawn upright into a picture of what its lines ink (as each is aligned, with a line's height of room round them), and that picture is placed turned. A quarter turn (90°, -90°, 180°) at full resolution is placed on whole pixels and not filtered, the part of a pixel that placement moves drawn into the picture instead, so it is sampled once, as upright text is, and keeps as sharp; another angle is sampled once more, by the turn. A picture past the page's pixel budget is drawn at a lower resolution and scaled up, as a frame that large already is.
   • Vector PDF and GeoPDF: the recording canvas keeps the glyphs with the turn as their transform (Canvas::with_transform), so the text stays selectable text.
   • SVG: <text … transform="rotate(a cx cy)">.
5. Hit test, selection and handles follow the turned box. Element::contains turns the point back into the element's box, so a click picks a turned text where it is drawn. The selection outline and the eight handles are drawn on the turned box, and the handle cursors turn with it. Dragging a handle of a turned text resizes it in its own frame and keeps the side opposite the handle where it was on the page (the centre it turns about moves). Snapping uses Element::bounds(), the rectangle the turned box takes up, for the moved text and for other elements' edges. With Pan and Zoom Map on, a selected text's handles still take the drag where they stick out over a map frame, as a turned source line along a map's edge needs; other elements' handles there give way to panning, as on main.
6. Format pane: a Rotation field (-180..180°) with 0°, 90° and -90° buttons, in the Element section of a text.
7. User guide: docs/user-guide/layouts.md describes Rotation under Text.

Choices

• On the text element, not on Element. The issue chose text only for now. Element::rotation() returns the text's turn and 0 for every other kind, so the hit test, the selection and bounds() already go through one place if a turned picture or rectangle is wanted later.
• The unturned box stays the element's box. Turning about the centre keeps the element where it was, and layout.update {"rotation": 90} on an existing text needs no other change. Its bounding rectangle is Element::bounds().
• Resizing a turned text from a handle is not snapped. Snap lines are horizontal and vertical, and a turned text's handles move along its own turned axes; moving it does snap, by its bounding rectangle.
• The automatic layout (layout.publication) lays out texts of its own, upright, so its place checks don't meet a turned text; anything that compares element boxes for placement goes through bounds().
• Normalized, not refused. A finite angle outside -180..180 is the same turn, so it is stored as that (450 → 90, -270 → 90) rather than refused, as the issue proposes. 180 and -180 are both kept as 180.

Tests

• text_rotation_round_trips_and_old_layouts_keep_their_bytes (map): 90 and -90 round-trip through a saved layout; a layout without rotation reads as 0 and is written back byte for byte; 450 read from a file is 90 after clamp; the normalization at 270, -270, 180, -180 and NaN.
• a_turned_text_is_hit_on_its_turned_box (map): the hit test and bounds() of a text turned 90°, its box unchanged.
• a_turned_text_runs_down_or_up_the_page (render): on a rendered page, an upright text is wide and short, a text at 90° or -90° tall and narrow, centred on its box; at 90° a left-aligned line starts at the top, at -90° at the bottom.
• a_turned_text_is_kept_turned_as_vectors (render): the recorded page keeps the turned text as glyphs, and replaying them draws the ink where the picture has it (within 2 px).
• a_huge_turned_box_is_drawn_at_a_lower_resolution (render): a box past MAX_SIDE is still drawn turned, through a scaled picture.
• a_turned_text_is_written_rotated (render, SVG): transform="rotate(-90 40 35)" on a turned text, no rotate( on an upright one.
• text_elements_take_a_rotation (engine): rotation on layout.addElement (number and numeric string) and layout.update; 450 and -270 stored as 90; not written when 0; kept through a save; "rotation": "x" and [90] refused with the text unchanged; refused on a rectangle (add and update); null changes nothing.
• a_turned_text_resizes_by_its_turned_handles (ui-egui, kittest): the handle at the turned box's end is the one picked; dragging it lengthens the text by the drag, its top and side staying put.
• a_quarter_turned_text_is_as_sharp_as_upright (render): at 300 dpi, with the box between pixels, a text at 90°, -90° and 180° has no more part-covered edge pixels per solid one than upright (it had up to twice as many when its picture was filtered).
• a_text_on_a_map_frame_keeps_its_handles_while_navigating (ui-egui, kittest): with Pan and Zoom Map on, a selected text's handle sticking out over a map frame resizes the text and leaves the map be; a rectangle's handle there still gives way to panning, as on main.

cargo fmt --check and cargo clippy --workspace --all-targets -- -D warnings pass locally (Windows). The tests of rustgis-map (284), rustgis-render (400) and the library tests of rustgis-ui-egui (817) pass; those of rustgis-engine (1278) pass except gdal_formats_open_when_gdal_is_installed, which needs GDAL 3.8 and this PC has an older one. The rustgis-ui-egui integration tests weren't run here (the disk was short of room for their binaries); CI runs them.

Size

About 470 added lines: some 220 of code (half of it the layout view's turned selection, handles and Format field), some 240 of tests, and the guide paragraph.

Limits

• No rotation handle for text. A line has a knob that turns it; a text turns from the Format pane or a command. A knob for text could come later, sharing the line's.
• No format version change, as with the other optional layout fields added before (letter_spacing, font, the legend's columns): an older RustGIS opening a layout with a turned text draws it upright, and drops the turn if it saves the file again. No map data is lost.
• The Rotation label is already in the catalogs; the 0°, 90° and -90° buttons are numbers. No i18n/*.tsv change.

Walkthrough

Text and dynamic-text layout elements now support normalized rotation. Layout commands, geometry, raster and SVG rendering, and editor interactions account for rotated text. Documentation and tests cover the updated behavior.

Changes: Text rotation

Layer / File(s)	Summary
Rotation data and geometry crates/map/src/layout.rs	Text elements store rotation, defaulting to zero. Layout geometry provides normalized angles, turned bounds, and inverse point mapping. Hit testing and tests use the rotated geometry.
Command inputs and persistence crates/engine/src/cmd/layout.rs, crates/engine/src/tests.rs	layout.addElement and layout.update accept rotation for text and dynamic text, normalize numeric values, and reject rotation for other element types. Publication-generated text starts at zero rotation. Tests cover defaults, normalization, persistence, and invalid inputs.
Rotated text rendering and export crates/render/src/layout.rs, crates/render/src/svg.rs	Raster and recording-canvas rendering handle rotated text. SVG adds a center-based rotate transform for nonzero angles. Tests cover placement, bounds, and output.
Editor controls and turned-box interaction crates/ui-egui/src/layoutview.rs, docs/user-guide/layouts.md	The editor adds rotation controls and updates turned-text handles, snapping, dragging, previews, labels, and cursors. Documentation describes rotation behavior and script support. UI tests cover resizing rotated text and text handles over map frames.

Full details: Title check

Explanation

The title "feat(layout): turn a text element by "rotation" (#1763, part 1)" matches the main change: optional clockwise rotation for layout text elements, applied across the engine, map model, render outputs, and UI. It names the scope (layout) and the feature. The "part 1" and issue reference are accurate context, though the title is slightly long at 63 characters.

Full details: Description check

Explanation

The description follows the template's required sections. It has a Summary that explains the change and why: text elements gain a rotation field for side-of-frame text, with the design choices and limits listed. It has a Testing section that names the tests added, the commands run (cargo fmt --check and cargo clippy), the test counts, and which suites were not run locally. It has a UI evidence section with two images: a before/after comparison of PNG output and a screenshot of the selected turned text with the Format pane. The Related issue section is filled in (Part of #1763). The section is detailed and specific. The only gap is that the PR is titled as part 1 of 2, and the author says the dashed-line work is in a separate PR, which is informational. The template's required UI evidence is present. Some images are cited by URL only, so a reviewer cannot confirm them from text alone, but the captions describe them.

AGENTS.md / saved-files rule: an older RustGIS silently drops the turn. The PR description says it openly: an older build draws this text upright and "drops the turn if it saves the file again." AGENTS.md (Never silent) says a file from a newer RustGIS must never be saved again without what that version couldn't read. docs/maintaining.md#saved-files-and-settings says a format's version goes up when "a file uses something an older reader would lose." A rotated text is exactly that case, and crates/engine/src/project.rs (check_format) says writers "must declare" a newer format once a change needs one.

The PR follows the precedent of letter_spacing, font and columns, which have the same gap. The rule calls existing silent losses bugs, so the precedent doesn't settle it.

Confidence: medium-high that this breaks the written rule; the maintainer decides how to meet it. Options: bump the project format and have writers declare it only when a layout holds a turned text, staging the reader release first as the rule asks; or record an explicit, reviewed exception in docs/maintaining.md. Either way, the PR should say which one it takes.

[elpidioassinaturas]

No change here: this is for a maintainer, as you say, and the PR text says it under Limits ("No format version change"). By the letter of docs/maintaining.md it is a loss: an older RustGIS draws the text upright, and drops the turn if it saves the file again; no map data is lost. The text's letter_spacing and font, and the legend's exclude (#518), columns (#1494) and labels (#1739), were added the same way, as optional fields with no version change, and the same question on #1494 and #1739 was left for a maintainer. .rgislayout files have no version to raise. Raising the project's FORMAT would make 0.6.0 refuse every project this writes, turned text or not, since write_format always writes the current one; a version written only when a layout has a turned text would avoid that, but would be the first of its kind. If a maintainer wants a version change here, I'll make it. Leaving this open for that view.

Code review

AGENTS.md

• Saved-file format not bumped (medium-high confidence). A turned text is a change an older RustGIS would lose, and the PR admits that older builds drop the turn on re-save. AGENTS.md (Never silent) and docs/maintaining.md both forbid that, so this needs a maintainer decision: bump the format, or record an explicit exception. Posted inline at crates/map/src/layout.rs:996. The same gap already exists for letter_spacing, font and columns, which the PR follows as precedent.

Bugs

• None confirmed. I checked the turned-box geometry (Element::unturned, bounds, the handle-resize shift in turned_resize), the picture placement in render::turned (the transform and scale-back), the SVG rotate(a cx cy) sign, the locked-element path in update, and the text overflow room against text_block. All hold.

Security

• None found.

Performance

• Nothing significant. A turned text allocates a box-sized picture per export, bounded by MAX_PIXELS.

Quality (nits, grouped; left for the release quality pass)

• layoutview.rs now has turn next to the existing turned (angle helper), and render/layout.rs adds another turned. The names are easy to confuse.
• The drag-preview outline (layoutview.rs:806) takes its rotation from app.layout.selected, not from the id drag_landing returns. It matches today only because a drag starts on the selected element. Low confidence it causes a visible bug.

Already raised earlier: 0. There were no prior review threads on this PR.

Review round 1 (claude-review on dbff7fc), fixed in b06b338:

• Drag-preview turn: the outline of an element being moved or resized now takes its turn from the id drag_landing returns, not from the selection.
• Names: the layout view's helper is now screen_turn and the renderer's draw_turned_box, so neither reads like the line's turned angle helper.
• Format version: answered on the thread at crates/map/src/layout.rs:996, left open for a maintainer.

Code review

Bugs

• No confirmed bugs. I checked the rotation normalisation, the turned-box hit test, the bounds() and snapping maths, the turned-resize maths (the new test's expected values work out by hand), the SVG rotate sign, the PDF glyph path, and the render transform order. All hold up. (confidence: high)

Security

• None found. The rotation argument goes through f(), which rejects non-finite values, and rotation() maps the rest into range. (confidence: high)

Performance

• draw_turned_box allocates a pixmap the size of the whole element box plus room, not the text's ink, up to the export budget. A large box with a short line allocates most of that for nothing, and the preview repeats it on every redraw. Inline comment posted on crates/render/src/layout.rs:2414. (confidence: medium)

Quality

• draw_turned_box returns without drawing or reporting if Canvas::new or the inner rectangle fails, so the text vanishes silently. The sizes are clamped, so this is probably unreachable. Inline comment posted on crates/render/src/layout.rs:2418. (confidence: low)

AGENTS.md

• The turned text is drawn in every raster and vector export, and it has tests for both lossy and clean inputs. No other rule breaks that I could find. (confidence: high)
• The format-version concern (a turned text drops its turn when an older RustGIS resaves the file) was already raised on crates/map/src/layout.rs:996. The PR author replied and left it for a maintainer. I did not repost it because the reply gives no new evidence. (confidence: medium that it breaks the "never silent" rule, as the earlier thread argued)

Already raised: 1 concern left alone (the format-version thread above). I posted 2 new inline comments.

Code review

Bugs: None found. I checked the rotation normalisation (rotation(), Element::unturned/bounds), the turned-resize maths (the anchor side stays put, and the test's numbers check out by hand), the drag commit path (drag_landing → layout.update), the lock guard in update, the PDF glyph transform (with_transform composes into recorded items), the SVG rotate(a cx cy) direction, and the picture offsets in draw_turned_box. The picture geometry matches text_block's size, pitch and alignment. The one handle_cursor call site is updated, and every ElementKind::Text destructure in the repo either names rotation or uses ... High confidence.

Security: None. Rotation input goes through given_num → f(), which rejects non-finite values, so "NaN" and "inf" are refused rather than silently becoming 0. Non-numbers are refused before anything changes. High confidence.

Performance: None new. The picture is now sized to the drawn ink (text_area), which is the fix the earlier thread asked for; I confirmed it is in 3bbbb1b. A single very long turned line can still request up to the page pixel budget, but that is bounded. High confidence.

Quality (low-confidence nits, grouped, not posted inline):

• Turned text is always resampled with FilterQuality::Bilinear (draw_turned_box), even for exact quarter turns and at fractional offsets, so turned text will look slightly softer than upright text. Comparing a 150 dpi export of a turned and an upright line would settle it. Confidence about 40%.
• The name label on a turned element is anchored at the topmost turned corner with LEFT_BOTTOM alignment. For a 90° text in the right margin (the PR's own use case) the name draws to the right of the box, possibly past the page edge. This affects the editor overlay only. Confidence about 50%.
• rustgis_map::layout::rotation is a generic free function next to Element::rotation(). Something like normalize_turn would read more clearly. Style only.

AGENTS.md: No violations found in the changed code.

• "Rotation" is already in the catalogs, and the label goes through tl!.
• The engine error strings are English, matching the neighbouring ONLY_TEXT_FONT messages.
• No new background command, so the cancel-list test is unaffected.
• Format version: left alone, see below.

Already raised (left alone, 3 threads):

• crates/map/src/layout.rs:996, format version for turned text, open. The code is unchanged and the author has answered it; this is for a maintainer to decide.
• crates/render/src/layout.rs silent-drop thread, resolved and answered. The early return in draw_turned_box is still there, and I agree it is unreachable.
• Picture sized to the whole box, fixed in 3bbbb1b. I confirmed the fix in text_area.

I did not build or run the tests; this review is from reading the code. No inline comments were posted, because nothing reached the bar for one.

Code review

I found no confirmed bugs. The turn maths, the hit test, the picture placement, the engine validation and the SVG output all check out against the diff and the surrounding code. One quality concern is posted inline, and a few lower-confidence notes are below.

Bugs

• None confirmed. I checked:
  • Element::unturned and bounds() are inverses and agree with the render transform.
  • rotation() normalises 450 to 90, -270 to 90, and 180 and -180 both to 180.
  • text_area matches text_block's alignment and its cut-off at r.height() + px. Lines beyond that cut-off were already dropped in the upright output, so the turned picture does not add a new truncation.
  • turned_resize keeps the anchor side fixed on the page; the test's numbers agree with that.
  • A locked text is refused before any write, because the lock check runs before the rotation is applied.
  • Every ElementKind::Text consumer either destructures rotation or is a test or a UI read.

Security

• None found. The new input is numeric only, and invalid values are refused with no change.

Performance

• Low (not raised inline): each turned text allocates a picture sized to its ink, up to the 60M-pixel page budget. Only a very large text reaches that size. The earlier box-sized allocation concern is fixed in 3bbbb1b.

Quality

• Low, quality: the inline comment on crates/render/src/layout.rs:2435 covers possible softening from bilinear resampling of turned text. Confidence is low to medium, and I did not render it.
• Low, design: the Format pane's X, Y, Width and Height show the unturned box, and alignment uses that box. A turned text's X and Y therefore do not match its visible edge. The PR documents this under "The unturned box stays the element's box", so this is a note for the maintainer, not a defect.
• Nit, for the release quality pass: the free function rustgis_map::layout::rotation shares its name with Element::rotation(), which makes call sites harder to read.

AGENTS.md

• The older-RustGIS format concern is already raised in the existing thread on crates/map/src/layout.rs, and the author replied. I left it alone and added nothing new.
• The silent else { return } in draw_turned_box is also in an existing thread, answered as unreachable. I left it alone.
• The rest of the diff follows AGENTS.md: no unwrap in non-test code, tl! for the new label, the layer boundaries hold, and no new dependencies.

Earlier concerns left alone: 3 (two of them answered, one fixed in the head commit). Posted again: 0. New inline comments: 1.

Review comments at @crates/ui-egui/src/layoutview.rs:
- Around line 290-292: Update handle_at so map-navigation guarding does not
suppress handles on selected, unlocked text elements; retain the guard for other
element types. In the cursor/navigation logic, treat a point recognized by
handle_at as a text-handle interaction so the cursor follows the handle and
dragging it resizes text rather than panning the map.

Code review

Bugs. No new bugs found. I read the changed code against its callers and checked:

• The turned-resize algebra keeps the side opposite the dragged handle fixed on the page.
• The inverse rotation in Element::unturned matches the forward rotation used for drawing.
• Handle indices stay unturned, and the cursor steps two handles per 90°.
• text_area agrees with text_block on alignment, the 200-line cap and the overflow cutoff.
• A rotation string such as "NaN" is refused, not zeroed, because f() drops non-finite values.
• update runs the lock check before the new rotation is applied.

Confidence is high for these readings. I did not run the tests.

Security. None. The new input is a single number, normalized and bounded.

Performance. No new concern. The turned-text picture is sized to the ink and is bounded by the export pixel budget. Confidence: medium-high.

Quality (nits, low confidence, could wait for the release quality pass).

• rotation() in crates/map/src/layout.rs has the same name as Element::rotation() and the rotation field. A name such as normalize_turn would read more clearly in clamp.
• The Format pane's quick-pick labels use format!("{quick:.0}°"). This is a numeric label, not a message, so the i18n rule does not clearly apply.
• handle_at now lets a text's handle take priority over map navigation. The thread on this was resolved after the author's last reply said the PR would not make text an exception. The code and that reply disagree, so the maintainer should confirm which is intended.

AGENTS.md.

• The saved-file rule ("never silent") is still open. An older RustGIS draws a turned text upright and drops the turn when it saves the file again. The author conceded the loss under the letter of docs/maintaining.md and deferred to a maintainer. Confidence: medium-high that this breaks the written rule.
• The rest of the diff looks compliant: no unwrap/expect/panic in non-test code, tl! for the new label, docs updated, screenshots in the PR body, no new dependencies or assets, and no std::time or other wasm-breaking code.

Earlier review threads. Five threads already exist on this PR. I left all five alone and posted nothing new:

• The saved-file thread: still open, as above.
• The resampling thread: the quarter-turn path now places the picture on whole pixels with nearest sampling. Other angles get one bilinear resample.
• The silent-skip thread: resolved by the author's argument that draw_turned_box cannot fail to build its canvas.
• The text-handle thread: resolved, with the note above.
• The picture-size thread: fixed in 3bbbb1b. I checked that text_area matches text_block.

I posted no inline comments, since no finding met the bar for one.
