# Frames: images and text boxes Covers `src/lib/editor/extensions/image.ts` and `textBox.ts` — node views, resize/rotate handles, wrap modes, frame offsets — and their ODF/DOCX legs. - **`image.ts`** (`Image`) — inline, as-character image atom (Word's "in line with text"). Attrs: `src` (data-URI), `alt`, `width`/`height` (**unscaled doc px @96dpi**, like `rowHeight`), `rotation` (CW degrees). The node view nests an `` in a rotated "rotor" inside an axis-aligned wrapper that reserves the rotated bounding box (so text reflows around it). The rotor's transform makes it a stacking context, so a selected `.image-node` is given a `z-index` above the header/footer layer to keep handles that poke into a margin grabbable. It has eight zoom-aware resize handles — corners aspect-locked, edges single-axis (width- or height-only) — plus a rotation-arrow grip, and shows a live "Width … × Height …" (cm) badge while resizing; resize deltas are un-rotated onto the image's own axes so handles track the pointer at any angle (drag math mirrors `tableRowResize.ts`; width cap = the cell or page-text-column, height cap = the page text height). `setImage` command inserts it; the toolbar button (ToolbarExpanded), drag-drop and paste (Editor.svelte) read the file via `FileReader` → data-URI and clamp the initial size to the page text box. **Text wrap:** the `wrap` attr (`'inline'|'left'|'right'|'topBottom'`) makes the image a *floating* frame — `ImageToolbar.svelte` (a per-image floating toolbar wired in `Editor.svelte` like `TableToolbar`) sets the mode; `left`/`right` float the wrapper at its anchor paragraph (text flows on the open side via CSS `float`), `topBottom` is a **full-width `float`** (text only above/below). All modes use `float` deliberately: an in-flow `display:block` on an inline-atom node view splits the paragraph's inline content into anonymous block boxes, which desyncs ProseMirror's inline view descriptor and makes it drop the following page-break spacer widget; a float is out-of-flow and avoids that. Dragging an **inline** image runs ProseMirror's native node move (the `dropCursor` plugin shows the caret). Dragging a **floating** image runs a custom drag (`ImageView.startReposition`) that **live re-anchors** the node to the text position under the cursor, so the float and text reflow in real time as you drag; it's rAF-throttled and only moves when the cursor's line changes (a float can't move within a line), and stays a single undo step (first move records history, later moves are `addToHistory:false` and get rebased on undo). A paragraph that contains an image paginates **atomically** (`pageBreaks.ts` — pushed whole to the next page, spacer placed before it) so a page break never splits the paragraph next to the image's float (where ProseMirror drops the spacer widget). **Frame offsets:** `wrapOffset` is the frame's left edge in the text column (Word's `positionH` posOffset, ODF `svg:x`), rendered as the float's near/far margin against the live column vars — an indented anchor paragraph can't skew it — and shared with `textBox.ts` through `frameMargins`. A `topBottom` float spans the column, so its own x moves the *rotor* inside the wrapper instead. `wrapOffsetY` (`positionV`, `svg:y`) is the frame's top below the anchor paragraph's, drawn for `topBottom` only — no text sits beside such a frame, where a side float's top margin would push away lines Word keeps. Chromium places **every** line after a full-width float below it, even the ones the float's top margin leaves room for, so a frame set below the paragraph top is sunk behind that paragraph's text at import (`sinkOffsetFrames`, both importers) and `ImageView.sinkToOffset` measures what the lines above it already cover, adding only the rest. Two `topBottom` frames set against **opposite ends** of nearby paragraphs (`wrapAlign`, from Word's `positionH` align / ODF `style:horizontal-pos`) share one band and float to their own sides instead: `pairAlignedFrames` (import/odt.ts, both importers) keeps the attr only for such a pair — a lone one reserves the whole band, which is what the wrap means — and scales a pair up to 15% wider than the column down to it, since Word lets the two overlap in the middle and two floats cannot. A frame Word puts *inside* running text still lands after it: browsers can't wrap text around a freely-positioned box (CSS Exclusions are unimplemented). Inline images stay as-char. Works inside table cells. Not available while editing a header/footer (the HF schema has no image node). Images live as data-URIs in the autosaved JSON; `autosave.ts` warns once if that exceeds the localStorage quota. - **`textBox.ts`** (`TextBox`) — block-level text box / basic shape with editable block content (`content: '(paragraph|heading|bulletList|orderedList)+'`, `isolating`). Attrs: `width`/`height` (px @96dpi; height renders as **min-height** — content grows the box), `rotation` (CW deg), `wrap` (image's `WrapMode`; `inline` renders in-flow, floats via CSS `float` like `ImageView.applyWrap`), `shapeKind` (`'textbox'|'roundRect'|'ellipse'` — ellipse renders via `border-radius:50%`), `fillColor`/`strokeColor` (`null` = transparent/no border), `strokeWidthPt`. Padding is the fixed `TEXTBOX_PADDING_CM` (0.15cm). The node has its **own group** (`group: 'textBox'`) so only the document admits it (`extensions.ts` widens Document to `'(block | textBox)+'`) — never in table cells, lists, header/footer, or other boxes; imports found there are flattened with a warning. `TextBoxView` mirrors `ImageView` (wrapper reserving the rotated bbox → rotor carrying fill/stroke/rotation → `contentDOM`); the rotor is out of flow and auto-grows, so a ResizeObserver refits the wrapper. **Click model (Word-like):** `stopEvent`/`isFrameHit` claim mouse events on a ~6px frame ring (rotation-/zoom-aware) → NodeSelection + handles (the shared `image-*` handle classes/CSS); clicks further inside pass to ProseMirror (caret). The box is browser-`draggable` only while node-selected, so PM's native block drag moves it without hijacking text selection. Commands: `insertTextBox()` (after the current top-level block, cursor inside), `setTextBoxAttrs()` (NodeSelection *or* cursor inside; helper `findTextBox`). `TextBoxToolbar.svelte` (wired in `Editor.svelte` like the image toolbar, also shown while the caret is inside a box) sets wrap/shape/fill/stroke. `trailingNode.ts` appends a paragraph after a trailing box; `pageBreaks.ts` paginates `.textbox-node` atomically. **Spacing:** a box lifted out of an anchor paragraph that held nothing else stands in for it, so it takes that paragraph's resolved `fo:margin-top`/`-bottom` as `spaceBefore`/`spaceAfter` (`ParagraphSpacing` covers `textBox` for that). Space above is padding — it adds to the block above rather than collapsing against it — which means the node is `content-box` and the rotor, centred in the padding box, gets half of it back.
