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.
New owned corpus test on PowerPoint-shaped XML: a custom-theme deck with
shadow, glow, soft-edge and reflection effects and every common text and
shape hyperlink, and a two-master deck with its own themes and layouts.
The one loss it found: a:hlinkMouseOver on text runs was dropped; it is
now read into RunProps::hover and written back.
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.
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.

Follow-up to the transition sound picker. The Sound box now lists
[Stop Previous Sound] and six built-in sounds (Chime, Click, Camera,
Whoosh, Drum Roll, Laser) that are synthesised as small WAVs when
chosen, so no sound files ship with the app; the same built-in sound is
embedded once however many slides use it. Loop Until Next Sound repeats
a sound in the show until another slide's sound or Stop Previous Sound.
PPTX reads and writes p:stSnd loop="1" and p:endSnd, keeps the sound's
file name in p:snd/@name, and setting a slide's transition to None no
longer drops its sound.

Transition sounds were read from and written to .pptx but could not be
set and never played. Transitions › Timing gets a Sound box ([No Sound]
or Other Sound…), backed by a new transition.sound command that embeds
an audio file on the selected slides (or removes it with none). In the
slide show the sound plays as its slide comes in and, as in PowerPoint,
keeps playing into the next slide unless that slide has a sound of its
own. Built-in sounds, Stop Previous Sound and Loop Until Next Sound are
still missing; the parity docs say so.

There was no way to make text see-through: the only Transparency
slider was the shape fill's. The new format.textTransparency command
keeps the text's colour and sets its alpha (replacing any it had, and
dropping it at 0). A run without its own colour takes the colour it
shows now, so inherited placeholder or theme colours stay as they are.
Gradient text gets the alpha on every stop. The Format Shape pane's
Text Options page gains a Text Fill section (colour and Transparency),
and the Shape Format › Text Fill dropdown has the same slider.

- Charts: every category/value/size cache draws from one chart-wide
budget of 1M decoded slots, so sparse ptCount/idx declarations across
many series can't expand far beyond the XML.
- Chart parts go through the same 96 MiB XML size guard as other XML.
- Package::open charges every inflated byte, including parts it then
discards, against a 4 GiB decompression budget and stops reading
entries once it is spent.
- Legacy OLE previews index each VML drawing once (shape id -> picture
part) instead of reparsing it and its rels for every object.

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.

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.
A shape's picture fill marked not to rotate with the shape turned and
flipped with it (rotWithShape was neither kept nor written: always 1).
PowerPoint keeps such a picture upright, stretched (or tiled) over the
box the rotated shape covers on the slide and clipped to the shape. Now
read, written (PictureFill::upright) and drawn so.
Wild synthetic set: picture fills on rotated/flipped shapes 12.89 ->
3.87.

- a:biLevel (Color > Black and White) was ignored. It is now read, written
and drawn: white where the luminance reaches the threshold, else black
(observed thresholds at 30/50/70% on colour swatches).
- a:alphaInv was ignored; an opaque picture with it is invisible in
PowerPoint. Now read, written and drawn.
- Grayscale, duotone and saturation weighed channels 0.299/0.587/0.114;
PowerPoint's export greys pure red to 54 and green to 182: Rec. 709

Wild synthetic set: recolour slide 7.60 -> 1.15, picture corrections
13.36 -> 7.36.

A table whose tblPr names no tableStyleId drew without any lines.
PowerPoint draws such a table with thin dark grid lines (as its "No Style,
Table Grid"); observed on a synthetic deck with and without the explicit
"No Style, No Grid" GUID. Such tables now read as the grid style.
Wild synthetic set: tables with cell margins/fills/styles 4.80 -> 2.82,
11.28 -> 10.15, 6.86 -> 3.16.

Gradient tile rectangles were dropped on import. PowerPoint's "from
corner" radial presets depend on them: fillToRect puts the focus on a
corner and tileRect stretches the gradient's box a whole size past it, so
the circle is centred on that corner and reaches the far one. Without it
(after the two-point radial change) such fills washed out. A linear
gradient now spans its tile rectangle; a radial one ends on the circle
around it, with the focus still placed in the shape's own box (fitted to
PowerPoint's export of the corpus deck tdf114848: mean diff over the
filled box 0.77). Round-trips through pptx.
Wild synthetic set: tile-rect gradients 16.74 -> 2.48.

Every transition and Effect Option was built in PowerPoint (COM), exported as
video and compared frame by frame with DeckCraft at the same progress
(mean abs diff over 150 variants 35.7 -> 15.0, 0-255).
- anim: transition_frame(kind, option, t, aspect) with measured curves
(smoothstep fades, ease-in-out moves, Cover/Uncover/Pan curves), directions
and option meanings, soft edges as per-corner opacity, 3-D effects as
perspective-projected cards, Dynamic Content moving slide contents over
cross-fading backgrounds (Source::OldBack/NewBack/OldContent/NewContent);
layer_mesh subdivides perspective quads so textures stay straight.
- New options: Page Curl Single, Glitter Hexagons, Shred In/Out, Zoom and
Rotate; PowerPoint-style Effect Options labels.
- render: composite_transition (CPU twin of the show), render_slide_part,
render_transition; deckcraft-cli render-transition FILE --slide N --t T.
- show: per-vertex opacity meshes, slide parts rendered once per transition.
- pptx: PowerPoint's elements and defaults (p:strips diagonal wipes, p14:warp
and p:newsflash for Zoom, p:zoom for Shape In/Out, glitter pattern, shred
rectangle/dir, prstTrans invX per preset, pageCurlSingle, defaults for
randomBar/doors/window/pan/zoom); PowerPoint reopens DeckCraft's files with
the same effects.
- Tests: measured curves, probes of which slide shows where at t, option
coverage, per-frame triangle budget, PowerPoint XML and defaults round trip.

A SmartArt drawing shape keeps its text rectangle in dsp:txXfrm, apart
from the shape's own box. The importer ignored it and laid the text out
in the shape itself. In list layouts the shape is a tall, narrow box
turned by 90 degrees, so the text came out as narrow vertical columns,
in the editor and in the exported PPTX.
The text rectangle uses the shape's coordinate space and is turned by
the shape's rotation plus its own:
- When it is the shape's text area shrunk by some margin, with the same
orientation, the shape keeps its text and the margin is added to its
insets.
- Otherwise (a rectangle reaching outside the shape, or turned against
it) the text moves to a new shape without fill or outline, placed on
the rectangle right above its shape in the diagram's group.
Both export as plain DrawingML (positive insets, an ordinary rotated
shape), which other readers lay out the same way.
Test: a SmartArt drawing built in the test, with a text rectangle wider
than its shape, a turned shape with upright text, and a rectangle
inside its shape; the laid-out text box is checked on import and after
a PPTX round trip.
* 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).

* #133: Selection pane engine: restack inside groups, Show/Hide All, Lock like PowerPoint
- arrange.bringForward/sendBackward/bringToFront/sendToBack and arrange.reorder work on a
group's children, which stay in their group (as PowerPoint's pane arrows and drag do);
steps that change nothing leave no undo step.
- selection.select (pane click: Ctrl toggles, children and top-level objects don't mix,
picking a hidden object shows it), selection.showAll (everything, children too) and
selection.hideAll (top level).
- shape.lock cascades through groups; locked objects can be selected, formatted and typed
in, but not moved, sized, rotated, flipped, reshaped or cropped (commands and canvas).
- PPTX: Lock reads and writes PowerPoint's full locking attribute set per element kind
(observed by saving locked objects from PowerPoint); partial locks aren't Lock.
