Every scheme other than the Latin, Roman and circled ones drew Arabic digits ("4." for
ea1ChsPeriod, "- 10 -" for arabic2Minus). Each is now written as PowerPoint's export draws it
(probe deck: one box per a:buAutoNum type and start value): Chinese numerals for ea1Chs/ea1Cht
(十, 十一, 二十一), digit-by-digit kanji with 〇 for ea1Jpn* (一〇), full-width digits for
arabicDb*, a full-width full stop after the East Asian ones, Thai letters (without ฃ ฅ ฆ) and
digits, Devanagari vowels, consonants and digits, the Arabic alphabet (arabic1Minus) and abjad
(arabic2Minus) and the Hebrew alphabet with a hyphen, and the Wingdings-style circles that go to
ten (circleNumWdWhite 13 → ③, circleNumWdBlack → ❶…). w04-lists s2-s4 drew wrong labels in 24 of
36 boxes.

Observed on PowerPoint's export of a wrapped Japanese paragraph (24 pt, 11 characters a line):
it breaks "けません（禁則処" / "理）。ー長音もで" / "す。っゃゅょ小書き文字", i.e. small kana
(っゃゅょ…), the prolonged sound mark and iteration marks never start a line (strict kinsoku),
where UAX #14's default allows it. And "し、句読点「、」や" / "「。」は…": with hanging punctuation on,
a closing bracket that overflows does not hang; only the ideographic comma and full stop (and
their full-width and half-width forms) do.

Observed on PowerPoint's export of long joined words:
- a line broken at a soft hyphen (U+00AD) ends with a visible hyphen ("Softhyphenatedwordsina-");
DeckCraft broke there but drew nothing. The hyphen now takes its room on the line;
- PowerPoint does not break after a zero-width space (it splits the word where it overflows
instead), where UAX #14 allows a break;
- an em dash ends a line but never starts one ("Em—dash—joined—" / "words—that—are—long—"),
where UAX #14 allows a break before it too.

Follow-up to the kerning rule: on the real corpus (ms6: titles condensed by 1 pt from the
master's title style) PowerPoint kerns condensed text, and a closer probe agrees for -0.6, -1,
-1.5, -2 and -3 pt (only -1.2 and -2.5 pt came out unkerned, which no simple rule explains). Only
spacing out by 0.6 pt or more now switches kerning off for the box. ms6 slides 2/7: 4.97 -> 6.44
-> back to 4.97, 7.05 -> 8.10 -> 7.05.

Every underline was a solid line 0.06 em thick at 0.12 em below the baseline, whatever a:rPr/@u
asked for. Underlines now sit at the font's own underline position and thickness (post table),
where PowerPoint draws them (Arial 96 pt: 10 px below the baseline, 7 px thick), and each style
is drawn as measured on PowerPoint's export: dbl two lines 0.55 thick spanning one thickness above
to the single line's bottom; heavy from one thickness above to 0.55 below; dotted dots and gaps one
thickness long; dashes three long with gaps of two; wavy a thin zigzag every 3.9 thicknesses. The
"words" style underlines spaces too, as PowerPoint draws it. Dashes and waves are new Deco line
kinds the renderer fills or strokes (warped text draws their boxes).
Underline slides: w14-xml s10 11.49 -> 10.43, s11 6.64 -> 4.06; w06-charfmt s3 9.66 -> 9.51,
s4 7.63 -> 7.44.

Tab stops were all left stops: a:tab/@algn was read and saved but ignored. As PowerPoint draws
them, the text after a tab (up to the next tab or line break) now ends at a right stop, is
centred on a centre stop, and has its first "." on a decimal stop (text without one ends there);
when that text is wider than the room before the stop it starts where the tab is, never further
left. Measured on PowerPoint's export: "right" ends at 180 pt, "12.5" and "1234.567" put the
point on the stop, "12,5" and "nodot" end at it.
A tab whose stop lies past the end of the line now starts the next line, so the text after it
sits on that line's first stop, as PowerPoint wraps "abcdefghij<tab>k<tab>l<tab>m…".

A run's solid fill with a:alpha was resolved into the glyph colour's alpha and also kept as the
run's fill opacity, and the renderer multiplied both: text at 60 % transparency drew at 16 %
opacity instead of 40 %. The colour now carries the transparency alone. PowerPoint's export of
"Transparent 60% text" (red) is a light red that now matches.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Small capitals were drawn at the full size of the run's first character: glyph runs grouped
cells by style and face only, so "HxHx" drew every letter at the capital's size on the small
capitals' narrower advances (letters overlapped). A lowercase letter in small caps now starts a
run of its own at 80 % (PowerPoint's small capital "X" is 0.81 of the capital "H" in Arial).
All caps and small caps mapped "ß" to "S" (the first character of "SS"); PowerPoint leaves a
character whose capital is a sequence as it is ("ß", "fi", "ʼn"), and maps the rest one to one.

PowerPoint kerns pairs (a:rPr/@kern) only while no run of the text body is spaced out by 0.6 pt
or more or condensed by 1 pt or more; then no run of that box is kerned, even runs without
spacing. Measured on Arial 40 pt "AVATAR": spacing 0, 0.01, 0.5, -0.6 and -0.99 pt keep the pairs
(146 px wide), 0.6, 0.8, 1, 1.5 and -1 pt drop them in every paragraph of the box (158 px plus the
spacing). DeckCraft kerned spaced titles, making "AVATAR"-like words 12 px too narrow at 40 pt.

PowerPoint does not resolve neutral characters with plain UAX #9: the language of each run
(a:rPr/@lang) decides. Measured with every space highlighted in its own colour:
- in a run of a left-to-right language (or none) punctuation and digits are left to right and a
space takes the direction of the character before it, so "abc HE1 HE2 def" shows the space after
the Hebrew words on their left, and an English sentence in an RTL paragraph keeps its full stop
at its end;
- in a Hebrew/Arabic run, neutrals between text of one direction take it, all others are right
to left, and digits are a number in the right-to-left text unless left-to-right text precedes.
Paragraphs with explicit embeddings keep the full algorithm. Bidi probe deck: mean diff 11.1 ->
10.0 on the four mixed-direction slides; corpus poi 6.660 -> 6.654, others unchanged.

The 48 MB cap on borrowed UI faces rejected macOS's only Hangul face (AppleSDGothicNeo.ttc, ~55 MB) and the picked Simplified Chinese face (PingFang.ttc, ~78 MB), so Korean and Chinese text in the title, recent files and notes drew as boxes. Raise the cap to 128 MB, as in PhotoCraft.
The same rule that highlights a transition direction now highlights an animation's direction and text build.

slide.new kept a leading tab as text, while text.set already turned it into a bullet level. The desktop --help flag was opened as a missing file.

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 table whose style the file defines (its parts and background drawn
since #292 and #294) edits like the others: the caret is laid out with
the file style's lettering (a regular header where the built-in style
bolds it), a double-click selects the word drawn there, a click moves
the caret to the clicked cell and a border drag resizes the columns
while the cell stays edited.
Tab moved into the cells covered by a merged cell, editing text that is
never drawn. It now goes to the next visible cell; Tab in the last
visible cell still adds a row, and Shift+Tab in the first cell stays.
Hovering a table border shows a resize cursor (new hit kinds
TableColumn and TableRow) and dragging it resizes, one undo step per
drag, as in PowerPoint:
- an inner column border moves between its two columns and the table
keeps its width;
- the right edge widens or narrows the last column and the table;
- a row's bottom border (the last one is the table's bottom edge) sets
that row's height, which stays a minimum: rows still grow to fit
their text.
Columns stop at 12 pt. Borders hidden inside merged cells aren't hit;
the left and top edges still move the table. A border drag while a
cell is edited keeps editing it. The drag goes through
table.columnWidth, which takes a new keepTotal option (the next column
absorbs the change), and table.rowHeight. Hit testing is done in the
table's own frame, so rotated tables resize along their axes.
- A double-click in a cell puts the caret where clicked and selects the
word there, as in shapes (it used to put the caret at the end).
- While a cell is edited, a click in the same table moves the caret to
the clicked cell and position; a drag selects text within the cell
and Shift+click extends only within it.
- A click in an already selected table enters the clicked cell at the
click; dragging the table still moves it.
- The release that follows a double-click no longer re-enters the text
at the click, which collapsed the word just selected (shapes too).
Cells are found from the drawn cell rects, so merged cells and rows
that grew to fit their text are hit where they are drawn.
Editing a table cell outlined the cell but drew no caret or selection,
and Up/Down/Home/End fell back to paragraph moves, because the text
layout used for drawing, hit testing and caret movement only existed
for shapes.
text::text_frame now lays out the edited text as it is drawn and gives
the transform to the slide, for shapes and cells alike: a cell's text is
laid out in its rect (merges honoured) with the cell's margins, anchor
and the table style's look, through the renderer's own cell_body and
cell_rects. layout_for and tools::text_pos use it, and the canvas draws
the caret and selection from it. The cell outline follows merged cells.
- ui-parity.md: title bar row; status line and history.
- ROADMAP.md: progress log line. Quick Access toolbar / title bar commands stays P (no
customization); no gaps.md entry covered this.
The Export dialog had no visible control: the native menu bar that lists
Export… is not installed, so only the command palette reached it. The
quick access row now has an Export button (the existing Export icon)
that opens the export dialog, enabled when a presentation is open.
- ui-parity.md: context menu row; status line and history.
- ROADMAP.md: progress log line. No checklist row changes score; no gaps.md entry covered this.
A right click on an unselected shape opened the slide's context menu
(Layout, Reset Slide...) because only the primary button reached the
pointer tool; the shape had to be left-clicked first. The right-button
press now goes through Session::pointer as PointerKind::ContextClick
(`contextclick` on the control channel and MCP) and selects like
PowerPoint before the menu opens: an unselected shape is selected alone
(a text box or placeholder is not put into text editing, nothing is
dragged), a selected shape keeps the selection, multiple selection
included, and empty slide clears it. In the box whose text is being
edited, the caret and text selection stay, and the context menu offers
text items (Paragraph, Bullets, Numbering, Link) next to Cut, Copy and
Paste, which act on the selected text.
- ui-parity.md: Direct manipulation row added; status line and history.
- ROADMAP.md: progress log line. The checklist rows involved (Text boxes, In-place text editing)
are already D; no gaps.md entry covered this.
While a text box or placeholder is being edited, every press inside its
box placed the caret, so the box could not be moved without leaving
editing first. Like PowerPoint, a band on either side of the box edge
(the hit tolerance wide, in the shape's rotated frame) is now its frame:
hit_test reports Hit::Frame there, the canvas shows the move cursor, and
a press leaves text editing, selects the box and drags it as one undo
step. A click without a drag just selects the whole box. Inside the box
the caret and text selection work as before; resize and adjust handles
still win. The text-click zone now follows the rotated box instead of
its axis-aligned bounds.
- 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.
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.
--all names files slide-01.png onward, so --slide 8 on an 8-slide deck looked like an off-by-one. The index stays 0-based, matching slide.go, and the error now gives the range and the file names.

Upstream ce1c7b7 ("Charts: axis number formats, automatic major unit,
hidden axes") replaced the value-axis scaling this branch changed, and
already draws #144's chart as 0-45 in steps of 5. Take its structure and
API as they are (axis_scale with fixed bounds/unit and a room-based
interval count, Chart::axis_scale(secondary, max_intervals), axis_range,
combo charts' secondary axis) and drop this branch's auto_scale.
On top of it, the Office rules upstream lacked:
- Automatic minimum: zero only when every value is >= 0 and the smallest
is below 5/6 of the largest; otherwise the first major unit at or below
min - (max - min)/20. All-negative data mirrors it (the axis ends at
zero only when the largest is above 5/6 of the smallest). Headroom is
5 % of the data range, as documented. Chart::axis_scale feeds it the
plotted extremes (stacked sums still count from zero, 100 % series are
0-1); axis_range and value_range keep returning zero-inclusive ranges.
- A fixed limit beyond the data makes the automatic end give way instead
of producing an inverted axis.
- The renderer stops values past the axis limits at the plot edge, on
both value axes.
The model tests from this branch are ported to the new signature with
ten intervals of room.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Value axes showed raw numbers ("800000") with a fixed ~5-interval scale and
fixed label gutters, deleted axes were still drawn, and data labels ignored
their number format, so Russian business charts read "516600000" where
PowerPoint shows "516 600 000 ₽".
- New deckcraft_model::numfmt: Excel number format codes (sections for
positive/negative/zero, quoted and escaped literals, _x padding, *x fill,
[$sym-lcid] currency, [colour]/conditions dropped, 0/#/? placeholders,
grouping with ',' or the locale's literal space, trailing-comma scaling,
%, General) with digit grouping and decimal mark from the chart's
language (c:lang: ru-RU -> "800 000", "12,5%").
- Reading: each value axis' numFmt, c:delete, scaling min/max and
majorUnit, for the primary and a combo chart's secondary axis; data
labels' numFmt (series, then group, else the source data's formatCode);
the chart's c:lang. The primary value axis is the one on the left
(bottom) and the secondary the one on the right/top or crossing at max,
whatever the plot groups' order.
- Scale (Chart::axis_scale): fixed bounds and unit where given, else the
data plus 5% headroom rounded out to the smallest 1-2-5 unit that leaves
as many intervals as the axis has room for labels, as PowerPoint does
(0-800 000 by 100 000, 0-7 000 by 1 000 on the sample deck).
- Rendering: labels in the axis format, gutters sized to the longest label,
deleted axes draw no labels and take no room, data labels in their own
format.
A combo chart (columns plus lines, often with the lines on a second value
axis) was read with each series' type but drawn as lines only, on one
scale, so a spend-and-clicks chart showed the clicks as a flat line along
the bottom and no columns.
- Reading: a plot group whose value axis isn't the first group's is on the
secondary axis (Series::secondary_axis, now set).
- Model: Chart::series_kind, on_secondary and axis_range (per axis; a combo
stacks only its stacked series).
- Rendering: bar-like series are drawn as bars (clustered or stacked among
themselves), the others as lines/areas over them, each against its own
axis; the secondary axis' labels go on the right. Line series use their
line's colour and width (where PowerPoint keeps them), also in the legend.
Long category labels wrap onto two lines.
RUSTSEC-2026-0194 (quadratic duplicate-attribute check) and RUSTSEC-2026-0195 (unbounded NsReader
namespace allocation) are fixed in quick-xml 0.41. deckcraft-pptx already reads attributes with
with_checks(false) and does not use NsReader, so neither is reachable today; the bump keeps the
workspace on a supported quick-xml and leaves one copy (wayland-scanner already locks 0.41.0).
decode_and_unescape_value() is deprecated in 0.41 (clippy -D warnings); decoded_and_normalized_value
(Implicit1_0, ...) is what the deprecated method now does.

A chart relationship must not be able to replace a slide or another package part when the deck is saved.
Co-authored-by: Cursor <cursoragent@cursor.com>
PowerPoint stores chart data in ppt/embeddings. Saving used to drop that part and the chart relationship, so the deck still rendered but the workbook was gone. An edit still omits the workbook rather than writing numbers that no longer match it.

animation.remove's remark belongs to its `ids` option, so describe shows
it there instead of as a note on the whole command. A command with an
all-optional set of parameters is suggested as a bare id.

The font scan also listed faces with none of the tables skrifa reads
glyph outlines from (glyf, CFF, CFF2, VARC): faces whose glyphs are
bitmaps only or are stored as outlines in Apple's hvgl table.
FontDb::outline, which the renderer reads glyph outlines from, returns
an empty path for every glyph of such a face. On macOS 27.0.1 the scan
lists "GB18030 Bitmap" (/System/Library/Fonts/Supplemental/NISC18030.ttf),
which stores its glyphs as bitmaps (bdat) and has no color glyph
tables, so the renderer draws none of the 27,544 characters it maps.
file_face_names now leaves out a face whose table directory has none of
those tables, as vectorcraft's font scan does (storytold/vectorcraft#781).
* Engine: file.info and PowerPoint-style print slide ranges (#76)
file.info reports what File › Info shows (name, path, format, unsaved
changes, slide and hidden-slide counts, sections, size on disk,
properties). file.export's PDF `slides` also takes the range typed in
PowerPoint's Print page ("1-3, 5", 1-based); bad or out-of-range text is
an error instead of a silent full export.

* UI: the File tab (Backstage) like PowerPoint's (#76)
File (first ribbon tab) or Alt+F opens a full-window view in place of the
ribbon, slides and status bar: a side menu (Back, Home, New, Open, Info,
Save, Save As, Print, Export, Close; Account and Options at the bottom)
and the chosen page. Esc or Back returns; Up/Down walk the side menu and
show each page as it gets the focus; Enter runs Save/Close/Options.
Laid out after PowerPoint for Windows as observed: 160-pt menu a step
darker than the page, outline icons, current page in the accent colour.
The start screen is now File › Home (as in PowerPoint), with only Home,
New and Open at the top and no Back. Pages call existing commands and
file helpers: file.new {theme} and the sample deck (Home, New); recent
files with search, Browse and Recover Unsaved (Open); file.info and
file.properties, Accessibility Checker, Revert (Info); file.save /
file.saveAs / file.export by type (Save, Save As); a PDF with the Print
page's slides, layout (full page, notes, handouts 1-9), hidden slides and
frames, opened in the system viewer or downloaded on the web, with a
page preview (Print, Ctrl+P); Create PDF, Create Handouts and Change File
Type (Export); appearance and About (Account); Preferences (Options).
Share (cloud) is left out.
Close and Ctrl+W now ask Save / Don't Save / Cancel about unsaved
changes instead of closing at once. The Export dialog shares
SlideApp::export_as with the Export page. New UI commands: app.backstage
{page}, app.closePresentation, app.print; ui.inspect reports the page.
New icons drawn in code: back, save as, account, recent, new file, open
folder.
