Unzip the archive. Read `content.xml`. +2. Parse `office:document-content/office:body/office:presentation`: + - Each `draw:page` → a `Slide`. The `draw:name` attribute → slide id. + - `draw:page-settings` (or `style:page-layout`) → slide dimensions. +3. For each `draw:page`, parse child `draw:frame` elements: + - `draw:frame` with a `draw:text-box` → `Shape::TextBox`. Parse + `text:p`/`text:span` for paragraphs and runs (text, bold, italic, + underline, font size, font family). + - `draw:frame` with `draw:image` → `Shape::Image`. Resolve the xlink:href + to the image file in `Pictures/`, store bytes in the MediaStore. + - `draw:frame` with `draw:rect`/`draw:ellipse`/`draw:line` → + `Shape::Geometric`. Map geometry and style. + - Unrecognized elements → `Shape::Passthrough` with raw XML. +4. Parse `style:style` declarations for theme (background, fonts, accent). +5. Map `draw:page-transition` to `Transition` when present. +6. Convert ODP units: 1cm = 360000 EMU. ODP uses cm/mm/in for positioning. + +### Writer (`save`) + +1. Build a valid ODP archive: + - `mimetype` (uncompressed, first entry — ODF requirement) + - `META-INF/manifest.xml` + - `content.xml` — the deck: styles + body + - `styles.xml` + - `meta.xml` + - `Pictures/` — images from the MediaStore +2. For each slide, emit a `draw:page` with `draw:frame` children: + - `Shape::TextBox` → `draw:frame/draw:text-box/text:p/text:span` + - `Shape::Image` → `draw:frame/draw:image` with embedded file + - `Shape::Geometric` → `draw:rect`/`draw:ellipse`/`draw:line` + - `Shape::Table` → `table:table` + - `Shape::Chart` → passthrough (ODP charts are complex; emit a placeholder + image or passthrough) + - `Shape::Passthrough` → emit raw XML +3. Theme → `style:style` declarations. +4. Transitions → `draw:page-transition` (when supported by ODP). +5. Animations: ODP has a different animation model — map build-in effects to + the nearest ODP equivalent with a warning when lossy. + +### Units conversion + +ODP uses centimeters by default: `1cm = 360000 EMU`. Convert model EMU +values to cm strings for positioning attributes (`svg:x`, `svg:y`, +`svg:width`, `svg:height`). + +### Tests + +- `load_simple_text_slide`: a hand-built ODP with one text box loads into + a Deck with a TextBox shape. +- `load_simple_image_slide`: a hand-built ODP with one image loads into a + Deck with an ImageShape. +- `load_extracts_slide_dimensions`: slide width/height mapped correctly. +- `load_unknown_element_passes_through`: an unrecognized element becomes + Passthrough (no panic). +- `save_simple_deck_produces_valid_odp`: save a Deck → valid ODP (starts + with the mimetype, is a valid ZIP). +- `save_load_round_trip`: load → save → load → assert structural equality + (shape types, text content, positions). +- `save_deterministic`: same Deck → identical bytes. +- `load_empty_deck`: an ODP with zero slides loads into an empty Deck. + +Build hand-crafted ODP files in-memory (ZIP + XML strings) for tests — do +NOT download real ODP files. + +## Acceptance criteria + +1. A simple ODP file with text and images loads into the slides-core model. +2. A deck exports to a valid ODP file (mimetype, valid ZIP, valid XML). +3. Round-trip preserves shape types, text content, and approximate positions. +4. Unrecognized ODP elements fall back to passthrough (no panic). +5. Output is deterministic. +6. Quality gate green. Privacy gate passes. No telemetry.
