## [0.2.3] — 2026-05-14
Single bug fix — stops the runaway growth of shape titles on drag /
click. No API change, no behavior change for code that doesn't hit
the bug.
### Fixed
- **Shape title text no longer balloons on every interaction.** When
a title's content overflowed the default box width at the
height-derived font-size, `_fillTextWithWrappedTspans` wrapped it
onto multiple lines. `actualH = measured.height + pad·2` then
exceeded the input `th`, that taller height got persisted back
into `metadata.title_box` on release, the next render derived an
even larger font, more lines wrapped, and the title grew
exponentially per interaction (`title_box.h` going
22 → 54 → 273 → … in three drags). `_renderTitleSibling` now
caps the font-size so the title fits the box width on a single
line (floor of 10 px), bounding `actualH` to one line of text.
The shrink-to-text rendering + handle-drag commit are unchanged;
with the cap in place the system has a fixed point instead of a
feedback loop.
## [0.2.2] — 2026-05-14
Follow-up patch to 0.2.1: restore body-grab on the editing shape,
keep the tooltip from blocking the satellite title label, and make
edit-mode survive a click on a sibling shape now that shapes are
`pointer-events: none`.
### Fixed
- **Body-grab restored on the editing shape.** With 0.2.1 flipping
every shape to `pointer-events: none`, the click-drag-the-body-
to-move-the-shape gesture stopped firing because the shape's
own pointerdown listener no longer saw any events. The
currently-edit-mode shape now re-enables `pointer-events:
visiblePainted` via a `.etcher-shape.is-editing` rule — only
THAT shape catches its own pointerdown; the rest of the shapes
stay invisible to events so pan/zoom still passes through them.
- **Tooltip no longer covers the title satellite.** When the cursor
was over a shape's movable title label, the hover tooltip
rendered above the parent shape — directly on top of the title
the user was trying to grab. The doc-level hover hit-test now
detects when the cursor is inside a title's bbox and suppresses
the tooltip for that hit; hover styling on the parent shape
stays applied so it's still clear which annotation is targeted.
- **Edit-mode and tooltip-pin survive a click on a sibling shape.**
Both outside-click handlers (the edit-mode tear-down and the
tooltip-pin tear-down) used `e.target.closest(".etcher-shape")`
to detect "is this click on a shape?" — but since 0.2.1 shapes
are `pointer-events: none`, the click's DOM target is OSD's
canvas, not the shape. The handlers now fall back to an
image-px hit-test via `_shapeAt(pt)` so clicking a different
shape switches edit mode or the pin instead of tearing down to
empty.
### Internal
- `_setHoveredShape/2` (was /1) gains an `onTitle` flag.
- New helper `_pointOnTitleOf/2` for the title-bbox hit-test.
## [0.2.1] — 2026-05-14
Patch release: pan / zoom now work over shapes.
### Fixed
- Scroll-wheel zoom and click-drag pan on the underlying viewer
stopped working whenever the cursor was over an annotation
(rectangle, circle, polygon, freehand, callout, text). Root
cause: shapes had `pointer-events: visiblePainted` so they
caught wheel + pointerdown before OSD's MouseTracker on the
canvas sibling could see them — pointer events bubble UP the
DOM, not sideways. Shapes are now `pointer-events: none`, and
hover + click are re-detected at the document level via
image-px hit-testing (reuses the eraser's per-kind point-in-
shape check). Hover styling, tooltips, click-to-pin, click-to-
edit, and dblclick-inline-edit all continue to work; pan and
zoom now pass through every annotation cleanly.
### Internal
- Renamed `_eraserHit/2` to a shared `_shapeContainsPoint/2`
helper. The eraser keeps a thin alias for readability at its
call sites.
- New helpers: `_shapeAt/1` (topmost-shape lookup), `_onShapeTap/1`
(shared tap-handling entry), `_wireGlobalShapeListeners/0` +
`_unwireGlobalShapeListeners/0`, `_setHoveredShape/1`.
- Tap-vs-drag disambiguation with a 5px dead-zone keeps a quick
click-without-drag firing the shape's selection / pin / edit
flow, while any drag-with-movement passes through to OSD's
pan unchanged.
## [0.2.0] — 2026-05-14
A backwards-compatible second release: two new shape kinds, an eraser
tool, undo/redo with full history, satellite titles, edge-resize
grabbers, polygon midpoint insertion, a visibility toggle, and a
complete programmatic API so consumers can drive the layer without
rendering its built-in toolbar.
### Added
- **Callout tool** (`kind: "callout"`) — blueprint-style leader-line
annotation: an anchor dot pointing at the image, a thin line to a
resizable text bbox (with a horizontal underline spanning the bbox
bottom). Text inside scales to fit the bbox.
- **Text tool** (`kind: "text"`) — freestanding text label drawn as
a click-drag bbox. Inline editor (`<foreignObject>` + `<input>`)
opens on commit and on double-click for re-edit. Font scales with
bbox height; bbox shrink-wraps to the text on release.
- **Eraser tool** — press-and-drag wipes shapes by sweep. Each shape
the cursor crosses dims (`.is-erasing`) for preview; release
flushes them all as a single compound delete. Idle hover (eraser
selected, no button held) previews the single shape under the
cursor.
- **Optional title field per annotation** — every kind can carry a
short label (`title varchar(200)`). On rect/circle/polygon/freehand
the title renders as a movable, resizable satellite group with a
dashed leader line back to the parent's nearest perimeter point
(leader auto-hides when the title is inside the parent). On
callouts the title is the in-bbox content. Drag to move (persisted
as `metadata.title_box`), 4 corner handles to resize, double-click
to inline-edit.
- **Edge-midpoint resize grabbers on rectangles** — small rounded
rect handles on each side; drag a side to slide one edge while
the opposite edge stays anchored. Distinct visual + `ns-resize` /
`ew-resize` cursors so they don't conflate with polygon midpoints.
- **Polygon midpoint vertex insertion** — every polygon edge now
carries a "ghost" midpoint handle that lights up when the cursor
is near. Grab it to insert a new vertex at that midpoint and place
it via a vertex-style drag.
- **Undo / Redo** — toolbar buttons + ⌘Z / ⌘⇧Z / Ctrl+Y keyboard
shortcuts. 50-op session history covers geometry, style, metadata,
title text, and deletes (including bulk-delete from the eraser).
Delete recreation honors a new `restore: true` flag so the consumer
can suppress its create-time UI (e.g. comment composer) on undo.
- **Visibility toggle** — eye / eye-slash button above the pencil in
Fresco's nav column. Hides/shows the entire SVG overlay with one
click.
- **Color picker** — bottom-toolbar swatches; persisted as
`style.color` on each annotation; vertex + title handles inherit
the shape's color via `currentColor` (no more always-orange dots).
Override the palette via `window.Etcher.colorSwatches`; initial
color via `window.Etcher.defaultColor`.
- **Tooltip slot extension API** — `window.Etcher.tooltipSlots = {
header, body, footer }` lets consumers replace the tooltip content
per-slot while keeping the wrapper (trash button, pin/unpin, hover
bridge) under Etcher's control. Default slots read generic
`metadata.{title,body,subtitle}` keys.
- **Complete programmatic control surface** on
`window.Etcher.layerFor(frescoId)` so every built-in button is
callable from outside. Methods grouped by mode, visibility, tool,
color, history, and shape selection/edit. Consumers can render
their own toolbar and drive the layer headlessly.
- **CustomEvents** for state changes:
`etcher:mode-changed`, `etcher:tool-changed`, `etcher:color-changed`,
`etcher:visibility-changed`, `etcher:history-changed`,
`etcher:tooltip-show / -hide / -pin / -unpin`.
- **Restored comment threads on undo-of-delete** — the etcher:created
payload for a restore carries `restore_from_uuid` so consumers can
re-link soft-deleted child rows (e.g. comments) to the new uuid the
server assigns to the recreated annotation.
- **`appendNavButton` mutable handle (Fresco 0.1.2+)** — Etcher's nav
buttons can now update their icon / title in place (used by the
visibility toggle to flip eye ↔ eye-slash).
### Changed
- Default `:tools` list on `Etcher.Layer.layer/1` is now
`[:rectangle, :circle, :polygon, :freehand, :callout, :text,
:eraser]` (all seven). Pass an explicit list to subset.
- Text + title + callout bboxes shrink-wrap to the rendered text on
every render; the stored geometry is rewritten to the shrunk
dimensions on release so storage always matches what's visible.
- Vertex handles now inherit the shape's color (`currentColor`)
instead of hard-coded orange. CSS hover / drag fills use
`fill-opacity` so they tint correctly with whichever color the
shape carries.
- Single-shape deletes now flow through the same compound
`bulk_delete` undo op the eraser uses, so the tooltip trash button
also gets redo support.
### Fixed
- Tooltip stops hijacking hover state on a different shape while
another shape's tooltip is pinned.
- Pinned shape keeps its `.is-selected` outline when the cursor
leaves it (was getting stuck visually deselected).
- Tooltip `.is-hovered` no longer sticks after the cursor leaves a
pinned shape.
## [0.1.0] — 2026-05-06
Initial release.
### Added
- `Etcher.Layer` Phoenix LiveView function component — attaches an
annotation overlay to a named Fresco viewer and adds a pencil button
to its nav column.
- `Etcher.Storage` behaviour — pluggable storage adapter contract with
four callbacks (`create/1`, `list_for/2`, `update/2`, `delete/1`).
- `Etcher.Storage.Default` — bundled implementation backed by the
`etcher_annotations` table. Reads the consumer's Repo from
`config :etcher, repo: …`.
- `Etcher.Annotation` Ecto schema for the bundled table (UUIDv7 primary
key, `target_type` / `target_uuid`, four geometry kinds: rectangle,
circle, polygon, freehand).
- `mix etcher.gen.migration` — generates the `etcher_annotations` table
migration into the consumer's `priv/repo/migrations/`.
- JS engine at `priv/static/etcher.js` — registers the `EtcherLayer`
LiveView hook, draws shapes as SVG overlays anchored to image
coordinates, emits `etcher:created` / `:updated` / `:deleted` /
`:selected` events.
- Bottom drawing toolbar with rectangle / circle / polygon / freehand
tools; pencil-button toggle integrated with Fresco's nav column via
`handle.appendNavButton/3` (Fresco 0.2+).
