* Text warps: draw WordArt prstTxWarp presets, round-trip their adjusts All 40 DrawingML text-warp presets now render instead of drawing flat text. A warp is a list of bands over the shape's text rectangle (insets ignored): fill bands stretch the ink of their lines between a top and a bottom guide (positions by arc length, one horizontal scale for the whole text), follow bands (arch, circle, button) set lines at natural size along an ellipse arc, lines stacking outwards on parallel curves, with no wrapping. Lines are shared over multi-band presets in order (ceil(n/k) per band). The guide curves were fitted to PowerPoint renders of synthetic decks of "I" bars (black-box observation, defaults and changed adjusts, 1-3 lines); most presets match within about a point on a 420 x 200 pt box. - geom: warp module (guides, presets, band mapping) with unit tests - render: glyph outlines and underlines flattened, subdivided and mapped - text: follow warps lay out without wrapping - model/pptx: BodyProps.warp_adj read from and written to prstTxWarp/avLst Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * Text warps: bands with fewer lines keep the fuller band's text height Multi-band fill warps (Deflate-Inflate, Button Pour) map a box as tall as the tallest band's ink onto every band, centred on the band's own ink, as PowerPoint does: a band holding one line next to a band of two keeps the line at the same size instead of stretching it over the whole band.

DeckCraft roadmap
Stage: alpha · next: beta, ~20 points and ~120–210 h away
Last reviewed: 2026-10-10 · Last updated: 2026-10-10 · Change: minor (hours to ~95% per audience added; ready 56% → 55%; stage stays alpha; previous: major, full re-measure against PowerPoint for Mac 16.113.4; restructured to the craftrules progress-docs standard) · Target: Microsoft PowerPoint for Mac 16.113 (Microsoft 365)
DeckCraft aims at full PowerPoint parity, and to be better: faster, open (a documented zip+JSON format plus PPTX), scriptable by agents (CLI, JSON control channel, MCP), and available everywhere (macOS, Windows, Linux, BSD and the web). This page is the summary; the detail is in docs/target-app-parity.md and the work list in docs/gaps.md.
Headline numbers
| Value | Kind | |
|---|---|---|
| Feature breadth | 79% weighted over 191 PowerPoint features (P0 92%, P1 75%, P2 36%) | measured: cargo xtask parity over docs/parity-checklist.md |
| Menu-bar coverage | 59% of 217 app-specific PowerPoint menu items matched by name (lower bound) | measured: script over the PowerPoint menu dump and the 226 commands |
| Ready for real work | ~55% | estimated: weighted dimensions below |
| Mainstream practitioner | ~53% | estimated: weekly-use areas × discounts for interaction (×0.92), stability (×0.92) and .pptx exchange (×0.88), method |
| Essentials user | ~62% | estimated: core features × discounts for launch (×0.90), clarity (×0.95) and opening received files (×0.90), method |
| Hours to beta | ~120–210 Opus 5.5 agent hours (~40–70 h with 3–4 agents) | estimated, docs/roadmap.md |
| Hours to full parity | ~365–650 Opus 5.5 agent hours | estimated, docs/target-app-parity.md |
Readiness by audience
| Audience | Ready | Opus 5.5 agent hours to ~95% | Work that dominates |
|---|---|---|---|
| Full target (ready for real work) | ~55% | 340–600 (~60% parallelizes: ~120–210 h wall clock with 3–4 agents) | Feature depth across all 20 areas, legacy .ppt/.odp and video export, localization in 11+ languages, GPU raster and hardware decode, AI features |
| Mainstream practitioner | ~53% | 150–250 (~50% parallelizes: ~70–120 h with 3 agents) | .pptx exchange (real-deck corpus, round-trip losses, EMF/SVG, embedded fonts) 45–75 h; depth in charts, animations, pictures, text, presenting, print/vector PDF 70–110 h; interaction (menu bar, Format Shape pane, font faces, dialogs) 25–40 h; stability 10–20 h |
| Essentials user | ~62% | 50–90 (~40% parallelizes: ~30–55 h with 2–3 agents) | Opening received decks (corpus subset, EMF, SVG icons) 25–45 h; Windows launch fallback and Close prompt 6–12 h; font faces, Tab, paste, print, show navigation 12–20 h; start screen, menu bar, palette 6–10 h |
Calibration is the same as for the full number (see docs/target-app-parity.md): a fix is 0.5–1 h, a checklist row to PowerPoint depth 2–4 h, a subsystem 6–35 h. The sets are nested, so essentials ≤ mainstream ≤ full. The full number is an additive weighted sum over the dimension table; only mainstream and essentials use multiplicative discounts.
Why alpha: all six of PowerPoint's core workflows pass the alpha gate
(docs/roadmap.md): build, open and save
.pptx, present, add tables and charts, share as PDF, review. Core workflows work end to end (build a deck, open and save .pptx, present with
transitions, animations, media and presenter view, export PDF), but depth, fidelity and polish
have known gaps, and PPTX has never been tested on a corpus of real decks. Beta needs ~75% ready
and no blocking gap in .pptx: the real-deck corpus, the round-trip losses (#70, #74, #77),
EMF/SVG pictures, the data-loss and startup-crash bugs (#60, #40, #59) and the beta list in
docs/roadmap.md.
