One EMF / WMF parity row naming both GDI clip regions and EMF+ playback; drop
the stale Tables, Charts, chartex and SmartArt rows that came back with the
chartex PRs; one SVG-gap sentence; one charts-gap paragraph.

A default export is 2 pixels per point. Without a resolution, Preview
treats those pixels as 72 dpi and the picture opens at twice the slide's
size. PNG pHYs and JPEG JFIF density now say scale times 72, so the
default is 144 dpi. Screenshots stay untagged.

EmfPlusClear paints the whole picture frame in its colour, ignoring the
world transform and clip, as GDI+ does; a transparent clear draws nothing.
With it every drawing record of MS-EMFPLUS 2.3.4 is played. The module docs
list what is deliberately ignored (rendering hints, rendering origin,
serializable image effects, terminal-server records, and StrokeFillPath,
which the specification names but gives no layout for), and the parity docs
no longer say EMF+ isn't drawn.

Export: a group with a diagram becomes a graphicFrame naming ppt/diagrams
data, layout, quickStyle and colors parts, plus the group's shapes as the
cached drawing (dsp). The data model is built from the outline (doc, node,
parTrans/sibTrans points and parOf links). A diagram read from a file keeps
its own layout, quick style and colour parts until its layout is switched.
Import: the outline is rebuilt from the data model's parOf tree, so
PowerPoint diagrams get the Text Pane. Their shapes stay the file's drawing
until the first outline edit (typed text isn't mapped back to nodes then).

Read the regionMap chartEx layout as a RegionMap chart (regions and
their colour values), write the part back as read while unchanged, and
when edited rebuild it with the original geography (projection, culture
and cached boundaries) carried over. With no map data in the repo, the
renderer draws each region as a value-coloured tile with a colour scale
and a note that the map itself is not drawn.

A SmartArt group now keeps its outline (Shape.diagram: layout + nodes with
levels) and its shapes are regenerated from it inside the group's child
rectangle. New commands: smartArt.nodes, setNodes, addNode (after, before,
above, below), removeNode, promote, demote and layout. Sub-points become
bullets in their parent's shape; the hierarchy layout is a real tree with
connector lines. Text typed into a diagram shape is read back first.
UI: a SmartArt Design contextual tab and a Text Pane (Enter adds a line,
Tab/Shift+Tab demote/promote, Backspace on an empty line removes it).

Read, keep and write every cx:lvl of a chartEx category dimension,
build a category tree from runs of parent labels, and draw treemaps as
nested squarified groups with banners and sunbursts as one ring per
level. Box & whisker honours quartileMethod="inclusive" (QUARTILE.INC)
on import, render, save and the chart.options command.

Histograms and Paretos bin their observations (bin count, bin width or
Scott's rule) and draw as touching columns, a Pareto with its cumulative
line on a percentage axis. Box and whisker charts draw exclusive-quartile
boxes, 1.5 IQR whiskers, means and outliers per category group.
Edited and new Office 2016 charts are written as chartEx parts from the
model (with the plain-chart fallback), so a waterfall stays a waterfall.
The chart menus list all seven types, and chart.options sets bins and
waterfall totals.

An owned corpus slice checks combo charts with data labels, merged
tables with diagonal borders, and text columns, autofit, vertical text
and a WordArt warp. Trendlines (type, order, period, forecast,
intercept, equation and R²) are now read and written.
An owned corpus opens, saves and reopens SmartArt and OLE kept as XML, audio and video bookmarks and trims, a section with a hidden slide, slide-number and date fields, ink, .glb models and animation repeat, bounce end and triggers. Relationship-bearing SmartArt and OLE, playback options and rewind stay with their open PRs.
An owned corpus of those kinds survives open, save and reopen. A run's
inner shadow, reflection and soft edge were dropped, and a bevel preset
with no kept 3-D XML was not written back, so import and export now keep
them.
An owned corpus of those element kinds survives open, save and reopen.
Paragraph default run properties, including a link, and action sounds
were dropped on save, so import and export now keep them.
Decks from SharePoint and Microsoft 365 carry customXml items (document
library metadata and content types), docMetadata/LabelInfo.xml (the
Microsoft Purview sensitivity label) and docProps/custom.xml. All were
dropped on save, so a labelled corporate deck came back unlabelled. They
are now kept verbatim with their content types, their own relationships
(itemProps) and the root or presentation relationship linking them. Kept
parts never replace a part the writer makes.

An owned corpus of those deck kinds survives open, save and reopen. The
check found the handout master — printed header, footer, date and slide
number — was dropped on save, so import and export now keep that part.
p:custDataLst points at ppt/tags/tagN.xml parts that add-ins such as
think-cell, Mekko Graphics and Office Timeline use to recognise their
decks, slides and shapes. They were dropped on open, so a saved deck lost
its add-in identity. The model now carries name/value tags on the
presentation, slides and shapes; the reader resolves every tags part and
the writer emits one tags part per holder, in the schema's element order.

Open, save and reopen decks we author, and compare package parts and
text. The check showed a notes master's header and footer were replaced
by an empty notes master on save.

A deck that embeds a TrueType or OpenType face, including one wrapped as Embedded OpenType, now draws with that face and saves it back. MicroType Express subsets stay in the file and still draw in a stand-in.

INTERSECTCLIPRECT, EXCLUDECLIPRECT and EXTSELECTCLIPRGN limit what later records paint, including a region made of several rectangles. A rotated map stores the bounds of the clip rectangle.

The writer emitted the legacy comment part only: replies were flattened
into sibling comments, the resolved flag was dropped. Modern PowerPoint
decks carry a second, threaded part (p188) as well - and DeckCraft read
both, importing every comment twice.
Export now writes the modern threaded part (p188:cmLst, with the slide's
commentRel anchor ext and the modern authors part) next to the flattened
legacy part, the same pair of parts PowerPoint itself writes: older
readers keep the legacy view, PowerPoint 2021+ and DeckCraft read
threads, replies and resolved state. The reader prefers the modern part
when both are present and scales modern positions as EMU instead of
legacy 1/8 pt, so real PowerPoint decks stop double-importing their
comments and keep their marker positions.
Comment ids are deterministic GUIDs from the existing tables::guid, so
exports stay reproducible without a new dependency.
Known limitation for a follow-up: comments anchor with
p188:unknownAnchor (schema-valid) rather than a slide moniker, which
needs part identity the model does not have yet.
Tests: threads plus resolved state round-trip on top-level comments and
replies, both parts and the anchor-rel wiring asserted in the raw
package, part numbering with comment-free slides skipped, legacy-only
and modern-only packages import each with their own position units, and
XML-special characters survive the trip.
- file-format-parity.md: SmartArt row notes the text rectangle; status line and history.
- ROADMAP.md: progress log line. No checklist row changes score (Insert SmartArt stays P), and
the gaps.md SmartArt entry (pre-drawn shapes only) still holds.
* ActiveX controls show their pictures
A slide's p:controls are read: each control with a p:pic (the image PowerPoint shows for it,
often a WMF) becomes a picture above the slide's shapes.

* Metafiles draw their text, pattern and hatch brushes
deckcraft-metafile (still kurbo + thiserror only, so it builds for wasm):
- Text: WMF EXTTEXTOUT/TEXTOUT and EMF EXTTEXTOUTW/EXTTEXTOUTA/SMALLTEXTOUT with the
selected font (CREATEFONTINDIRECT, EXTCREATEFONTINDIRECTW: face, signed LOGFONT height,
width, weight, italic, underline, strike-out, escapement, charset), text and background
colour, background mode, TA_* alignment and TA_UPDATECP, the dx array (ETO_PDY pairs too),
ETO_OPAQUE fills and ETO_CLIPPED clips. 8-bit strings decode through their charset
(Windows-1252/1250/1251; symbol fonts keep their codes at U+F000; double-byte sets keep
their advances). The neutral Item::Text carries a text-space-to-picture transform, so the
mapping and escapement are folded in and glyphs are never mirrored.
- Brushes: WMF DIBCREATEPATTERNBRUSH, EMF CREATEDIBPATTERNBRUSHPT and CREATEMONOBRUSH, and
BS_HATCHED, as Item::Pattern tiles in 96-dpi pixels; WMF PATBLT. The XOR / AND-pattern /
XOR see-through shadow of old PowerPoint WMFs draws its pattern in the XOR colour.
- MFCOMMENT escapes with an embedded EMF are ignored: PowerPoint draws the WMF's records.
- Pattern pixels and text count against the byte budget; strings are capped.
deckcraft-render draws text through deckcraft-fonts with the face slide text would use
(document_face), symbol fonts mapped as bullets map them (deckcraft_text::symbol_char, now
public, with Webdings), per-character fallback, the file's advances, GDI cell metrics for
top/bottom alignment, underline/strike-out and synthetic bold/italic. Tiles below 1.5 output
pixels per cell are drawn as their average colour.
On the 24 corpus slides that show a metafile, mean abs diff against PowerPoint goes from
28.31 to 5.06 (with the OLE/ActiveX preview commits).
