The Curvature tool built its curve as a uniform Catmull-Rom: both handles of a
smooth point a sixth of the chord between its neighbours, the ends of an open
path without handles. Uneven spacing overshot or looped, a J or U from three
points bent sharply at the middle with straight legs, and the end segments
looked flat.
- `curvature_spline` (draw2.rs) makes each stretch of three points follow the
circle through them: a smooth point's tangent is that circle's
(`smooth_handles`), each handle `chord / (3 cos²(α/2))` long, α between
handle and chord capped at 90° (`arc_handle`). The ends of an open path
mirror their neighbour's tangent in their chord (`end_handle`). A turn
tighter than 30° (`TIGHT_TURN`) shortens its handles, so a narrow V comes to
a point. Degenerate points become corners. `path.curvature` and the rubber
band use it.
- `catmull_rom` is unchanged for the Pencil and Paintbrush fitting.
- `bend_last` (from: smooth), `curvature_move` on a smooth point, the point
`curvature_insert` adds on a straight segment, and `path.convertAnchor` to
smooth without x/y (`curvature_smooth`) use the same rule.
- `curvature_extend` gives the new end its end handle unless Alt-clicked
(`corner` param on `path.curvatureEdit`).
- Neighbours of a point dragged on an existing path keep their tangents (a
Pen-drawn shape isn't reshaped); the path being drawn re-curves throughout.
When entering text edit mode via double-click from a selection tool
(Selection or Direct Selection), pressing Escape now returns to the specific
tool used before double-clicking (rather than always falling back to
Selection).
Additionally, when editing text while in isolation mode (such as when drilling
into nested groups with the Selection tool), pressing Escape exits text editing
while keeping isolation mode active; a second Escape press is required to exit
isolation mode.
- Record the previous tool in TypeTool on double-click from canvas.
- Return to prev_tool on ToolKey::Escape, consuming the key in shortcuts when claimed.
- Add unit test in vectorcraft-tools verifying Escape returns to prev_tool.
- Add integration tests in vectorcraft-ui-egui verifying Escape returns to Direct
Selection and that isolation mode persists until a second Escape.
- Update docs/target-app-parity.md and ROADMAP.md.
With the Direct Selection tool ("white arrow", shortcut 'a'), double-clicking
a text element (either standalone or nested inside a group) now switches to
the Type tool and immediately positions the caret at the clicked character,
matching the behavior previously introduced for the Selection tool in #284.
- In DirectSelectionTool::pointer, detect double-click hits on NodeKind::Text
when !self.group and emit Action::SwitchTool("type").
- Group Selection (group: true) retains its existing group cycling behavior.
- Add unit test in vectorcraft-tools verifying tool switch on both standalone
and grouped text.
- Add headless egui integration test in vectorcraft-ui-egui verifying tool switch,
caret positioning, and inline editing without triggering shortcuts.
- Update docs/target-app-parity.md and ROADMAP.md.
Illustrator's View menu has Hide/Show Template (Shift+Ctrl+W) to leave
template layers off the screen while tracing. VectorCraft drew them (dimmed)
whatever the view, with no way to hide them short of disabling the template
option on each layer and losing the dimming.
- `view.template` toggles `ViewFlags::templates` (default on, kept across
settings files); the View menu lists Hide Template after Lock Slices, and
the label flips to Show Template.
- The canvas renders with the new `RenderOptions::hide_templates`, which
leaves template layers out and nothing else; `skip_templates` (exports and
thumbnails) also drops guide paths, so it is not reused.
- The fifteen menu catalogs translate both labels; `DYNAMIC_LABELS` lists them.
Tests: render `hide_template_leaves_only_the_template_layers_out` (the
template layer's square and image go, a guide path on another layer stays);
canvas `hide_template_leaves_template_layers_off_the_canvas` (real egui
frames: painted pixels, none after Hide Template, the same after Show
Template, each re-rendering once); the dynamic-label and catalog tests cover
the new pair.
