dotCooCoo 01b3599227 Variables: binding errors name the command and say when a layer is hidden
Binding art in a hidden group or layer failed with "node N is locked",
even when nothing was locked. The error now says whether the object is
locked, is in a locked group or layer, or is in a hidden group or layer.

Make Text Dynamic and Make Visibility Dynamic reported their errors under
`variable.makeDynamic`, which is not a command id. They now name
`variable.makeTextDynamic` or `variable.makeVisibilityDynamic`.

dotCooCoo 00b02c1bdb Variables: Update Data Set writes only the variables the active data set holds
A data set can hold values for only some variables: `dataset.new` and
`dataset.set` store only the values they are given, and selecting the
data set leaves the other variables alone. Update Data Set replaced the
active data set's values with the values the art reports for every
variable. After one Update, a data set that set only a visibility
variable also held the current text of the bound type, and selecting it
again wrote that text back. Update also dropped a variable's value when
its objects were locked or inside a hidden or locked layer or group,
because such objects report no value.

`dataset.update` now writes the art's current value for each variable
the active data set holds, and keeps the data set's value when the art
reports none. A variable that the data set does not hold stays out of
it, including one defined after the data set was captured;
`dataset.update {all: true}` also adds the other variables that the art
reports a value for. The reply adds `left`, the variables it did not
write. The Variables panel's Update Data Set button and menu item run
it without `all`.

dotCooCoo 35f43d631f View: Proof Setup simulates tritanopia
View › Proof Setup had two color blindness items, protanopia and
deuteranopia. A third item, Color blindness – Tritanopia-type, proofs
the canvas with a tritanopia simulation, and the Separations Preview
panel's Proof Setup list offers it too. `view.proofSetup` takes
`target: "tritanopia"`.

The simulation follows Brettel, Viénot and Mollon (1997): a color
keeps its L and M cone responses, and its S response is replaced so
that it lies on one of two half-planes. Both contain the neutral
axis; one passes through the 485 nm color and the other through the
660 nm color. The neutral axis runs to the display's white, so grays
keep their value. The matrices are computed at
compile time from the published inputs cited in the code. The
protanopia and deuteranopia matrices are unchanged.

dotCooCoo d68e14a393 Pencil and Paintbrush: with Keep selected off, a drawn path is not left selected
A Pencil or Paintbrush stroke always left the path it drew or continued
selected. The reference app's Pencil and Paintbrush options have Keep
selected for this, and VectorCraft's Tool Options had no such row.

The Pencil and Paintbrush Tool Options now have a Keep selected
checkbox, on by default, which keeps today's behavior. When it is off,
a new path is not selected and the selection stays as it was, and a
continued path is removed from the selection while the rest stays. The
stroke is still one undo step. The option persists like the tools'
other options, and path.freehand and brush.freehand take keepSelected.

EricKuckandClaude Opus 5.5 0a4e9ea8c8 SVG export: a chosen artboard's file leaves out the art of other artboards inside a shared group

dotCooCoo 0c3a5929c7 Type: area type opens and lays out with at most 100 rows and 100 columns
In a dev build, opening a native file whose area type has 2^60 rows
or 2^60 columns failed with an internal error ("capacity overflow"),
and opening one with 2^32 rows and 2^32 columns failed with "attempt
to multiply with overflow". Text layout reserved room for rows times
columns frame cells. `text.areaOptions` keeps both counts within 1 to
100, but reading a document kept the counts the file gave.

Reading a document now clamps each count to 1 to 100
(`AreaOptions::MAX_ROWS_COLUMNS`): a larger count reads as 100, and 0
reads as 1, as layout already treated it. Text layout clamps both
counts the same way. Area type with 1 to 100 rows and columns lays out
as before.

The cells of a frame now share one copy of the frame's flattened
polygons and one copy of the flattened text wrap shapes. Each cell held
its own copy: in a dev build, a test process that laid out text in 100
rows and 100 columns of a circle frame of radius 1,000,000 pt peaked at
1.33 GB of memory, and now peaks at 100 MB.

dotCooCoo ac4d69032c Artboards: copied artboards take a free id and keep their own guides
Duplicate Artboards, the Artboard tool's Alt-drag (artboard.move with
copy) and Paste of a copied artboard gave the new artboard the largest
artboard id plus one, saturating. In a document with an artboard id
of 4,294,967,295 (u32::MAX), which only a hand-made file has, the copy
got that same id. Artboard guides record the id of their artboard.
Deleting either of the two artboards with that id then deleted the
guides of both, and guide.list reported the copy's guides on the
other one.

push_artboard_copy now takes the id from Document::next_artboard_id,
as artboard.new and Convert to Artboards do. Since the #1718 fix, that
function returns the smallest free id when the largest is u32::MAX.
In a document whose artboard ids are all below u32::MAX, a copy gets
the same id as before.

dotCooCoo 93742621bc Align: Distribute follows Align to Artboard
With Align to Artboard chosen, the Align panel's six Distribute Objects
buttons and its two Distribute Spacing buttons acted on the selection.
object.distribute and object.distributeSpacing took no to or artboard
param. Distribute Objects kept the outermost objects where they were
and did nothing with two objects, and Distribute Spacing kept the first
object's left or top edge and the last object's right or bottom edge
where they were.

Both commands now take to ("selection", "artboard" or "key") and
artboard, and the panel sends its Align To choice as to. When to is
"artboard", the first object's left or top edge goes to the artboard's
left or top edge, and the last object's right or bottom edge goes to
the artboard's right or bottom edge. Distribute Objects spaces the
other objects evenly by its button's line, and two objects are enough.
Distribute Spacing without a spacing value makes the gaps between the
objects equal. Both commands use the same artboard as object.align.
The app passes the active artboard to both commands, and recorded
actions leave it out, so an action plays on the artboard that is
active when it plays. With "selection" or "key", or without to, both
commands work as before. Distribute Spacing with a spacing value still
keeps the key object in place with each of the three to values. With
anchor points selected, both commands still space the points among
themselves and do not use to.

lloydandClaude Opus 5.5 8d288337f5 Place keeps a clipped group's clip
Place flattened every top-level layer into its objects, so an SVG's clipped top-level group lost
its clip and its clipping path came in as a loose, invisible path; sublayers lost their clips the
same way. A clipping layer is now placed as one clip group, for SVG/DXF and for the art placed from
an artboard (PDF, EPS, placed documents) alike.

midasmatterhorn 3af1976d19 transform: Transform Again repeats a Transform Each (#1732) 2026-10-16 02:01:50 +07:00
Dan Green 6ce1a622be Part of #868: legacy .ai type as text objects and hidden objects kept; legacy type read
Type is written as version 7 text objects (§15): point type, area type and type on a path, with
fonts by PostScript name re-encoded to Windows-1252, and each run's paint, size, scaling,
tracking, leading, alignment and indents; type 8-bit text can't hold (or all, with outlineText)
is outlines. The format hides only layers, so hidden objects go to a hidden layer above their
own (hiddenObjects "layer", the default), are left out ("omit") or show ("visible"). The .ai
reader reads legacy type (To … TO, TE, %AI3_BeginEncoding) and ignores Ar; the import fuzzer
gets legacy type tokens.

Dan Green bcae7ca486 Part of #868: Save As .ai offers Legacy (version 7), with Transparent Images and an artboard range
aiVersion 7 saves through the legacy writer, one file per artboard; range picks the artboards
and document.save writes them again. Appearances are expanded first. Transparent images
(see-through pixels, opacity or a blending mode) are flattened with the art under them into
opaque images clipped to where they change it (transparentImages "flatten", the default), or
left out ("omit"); both warn.

bflatastic d9c9526898 Keyboard Shortcuts: shortcut set reading and matching stay bounded on hostile files
A set whose entries sit in long, deeply nested sections kept every section's names again for each entry (up to hundreds of megabytes from a 4 MiB file); the names kept over all entries now stop at 8 MiB. Name matching compares character pairs in linear time, so a 20,000-entry set of long names is matched in about 2 s instead of 17 s.

dotCooCoo 8c889279f8 Keyboard Shortcuts: importMatches.list answers an unknown parameter key with an error
Since #1442 (3acc29f8), a caller outside the app gets an error for a
parameter key that the command's params description doesn't name, and
every_description_parses requires each top-level entry of the params
object to start with a key. The note on query in importMatches.list had
a comma at the top level ("text in the name, target or label"), so the
description didn't parse: the test failed, and the command took any key.
The note is now in parentheses, and the command takes kind and query.
A test checks that shortcutSet.read and the three importMatches
commands take every key they read and refuse a misspelled one.

dotCooCoo 8c14609370 Keyboard Shortcuts: Import… and File › Open read text shortcut sets (.kys)
A shortcut set another app saved as slash-name text (a .kys file whose
text starts with a slash name and "{", such as "/Menus {") opens in
Import Shortcut Set from File › Open, from Edit › Keyboard Shortcuts ›
Import… in the desktop app, or from a drop on the window, whether or
not a document is open. The dialog proposes a target for an entry when
an earlier import kept one for that name, or else when one tool,
command or panel matches the name clearly by its id or by one of its
labels. It decodes the file's key and modifier codes from the codes
earlier imports kept, from the example in the AiCommandPalette README
(/Key 48 for the 0 key, with /Modifiers 0 taken as no modifiers), and
from VectorCraft's default shortcuts where at least two entries vote and
four votes in five agree. The user picks the remaining targets, presses
the key for each unknown key code or marks it No equivalent, and chooses
the modifiers for each unknown modifier code. Apply assigns the ready
rows with the Keyboard Shortcuts rules: a tool takes a single key,
optionally with Shift. It goes through the rows from the last one back
and leaves a row out when a later row it applies has the same shortcut
or the same tool, command or panel. Keyboard Shortcuts then shows the
result as unsaved changes until the user clicks OK. Copy Report copies
the set's name, the rows Apply leaves out and the parts of the file that
weren't read.

- shortcutSet.read is a query command: it reads a set and does not
  modify the document or the preferences. It returns each entry with
  its section, codes and line, and up to 1,000 skipped tokens, each cut
  to 80 characters. It reads at most 4 MiB of text and 20,000 entries,
  skips blocks nested more than 16 deep and cuts names at 1,024 bytes.
  With a path it reads at most 4 MiB and 4 bytes of the file, and with
  --automation-read-root (#832) the path must lie inside the read root.
  A file whose text starts with "<", such as an XML shortcut file saved
  as UTF-8, fails with "This shortcut file is in a form VectorCraft
  can't read."
- importMatches.list, importMatches.set and importMatches.reset read
  and change the matches kept with the preferences; resetting the
  preferences keeps them. With Remember My Choices on (the default),
  Apply keeps the targets and codes the user chose, and for the rows it
  assigns, it also keeps the matched targets and the codes decoded by
  agreement. A later import proposes them.
- The name matcher compares a name with ids by exact match and shared
  words. It compares the name with labels, in English and in the
  interface language, by exact match, shared words and character
  pairs. It proposes a match only when one tool, command or panel
  scores at least 0.6 and at least 0.1 more than the next one.
- When Import Shortcut Set is opened from Keyboard Shortcuts, Cancel,
  Escape and ui.dialog.cancel close it and return to Keyboard Shortcuts
  as it was (dialogs::PARENT). A document's queued Missing Fonts dialog
  (#792) opens after Keyboard Shortcuts closes.
- File › Open has a "Shortcut sets" filter, and in the desktop app
  Keyboard Shortcuts' Import… shows .json and .kys files.

bflatastic 7f1ad31a7b Fix #1881: a Ctrl/Cmd drag while typing keeps what was typed
With the Type tool editing, a press with Ctrl (Cmd on the Mac) lends the
Selection tool for the drag. Its drag joined the open typing session, so its
preview started from the document before the typing: the type moved or
scaled and lost what had just been typed. The typing is now kept as its own
undo step before the lent tool takes the press, as Undo already does, and
typing goes on after the drag.

bflatastic 0efcaeb558 Importers: a brush that draws itself by name no longer crashes
A scatter brush whose art is an instance of a symbol stroked with that brush, or any brush whose
art is painted with a pattern whose tile is stroked with it, drew itself without end: a stack
overflow in a hand-written native file. Brush pieces already strip the brushes of their own
strokes; now what they draw by name that would draw a brushed stroke (a symbol instance, or a
pattern paint, also through the symbols and patterns those use) is left out too, in one place
(`stroke_pieces`, which every renderer and exporter calls with the document).

Probed the rest of item 2 of the depth follow-up with hand-written hostile inputs, kept as tests:
graph designs of deep art and of a symbol holding itself, Affinity groups nested to and past
both of its reader's caps, DXF blocks inserting themselves, EMF/WMF saving states without end,
and plug-in manifests and output nested 30,000 to 100,000 deep. None of them overflowed.

The rollback undid the batch's interaction, which holds the art, the selection

and an Undo step (which ends the interaction) left the art and the history
undone. The batch now keeps the documents as they were and puts them back,
and settles a drag or typing in progress first, as Undo does, instead of
running inside it and keeping its baseline as the batch's step. Files the
steps wrote stay written.

to redo), one that changed nothing is dropped.

bflatastic 1f4daf519d Image Trace: enhanced versions of the presets
Each documented preset has an enhanced version (`enhanced: true` in
`imageTrace.make`, an Enhanced checkbox under the panel's preset): the preset
with Auto Grouping, and with Shapes in all but High Fidelity Photo. Gradients
stay an option. Flat Logo, a preset of our own, has none. The legacy presets,
and documents traced with them, are as they were.

So that an enhanced preset is no worse than its preset on that preset's inputs:
- A hole that one colour fills is the same shape as the path that fills it, so
  the two still share one outline (a shape beside a fitted hole left slivers).
- A rectangle is as large as where its sides lie on average, not their farthest
  points.
- Auto Grouping keeps the paths of a group in the order they were traced in. It
  put a path first and what is inside it on top: a white counter traced under
  its black letter was then painted over the letter's edge, a light seam
  (Default with Auto Grouping, edge dE 10.24 -> 9.88; legacy 10.05).

The harness measures every enhanced preset beside its preset.

Create: Strokes drew every line with round caps: a square-ended line 10 px wide
had its corners 2.94 px outside the stroke.

- A line's ends are square when its ink reaches as far a third of the width to
  either side of its middle as along it (a round end stops short there by a
  seventh of the width); told from lines 3 px wide and more, all the ends of a
  line together. The stroke then has square caps (`TracedPath::square_caps`).
- The last points of a wide line's skeleton can turn towards a corner of its
  end. An end that has left the line the skeleton followed a width back (by a
  quarter of the width, 1 px at least) is put back on it; and an end may be
  pulled back as well as pushed out to where the ink ends.

Outline on the thin-line inputs: largest distance from the art 2.94 -> 0.88 px
(clean 2.94 -> 0.41; aliased 0.88 -> 0.81), mean 0.055 -> 0.050 px, anchors
14 -> 10.

GameDirection b5bc8f0d19 Corner Radius: a field per corner of a live rectangle, with a link toggle
The Corner Radius field in the Properties and Transform panels has a
link toggle behind it (the "singleCornerRadius" preference, on by
default). When the link is on, one field sets every corner, as before.
When it is off, the panels show one field for each corner of a live
rectangle: Top Left, Top Right, Bottom Right and Bottom Left. Each field
sets its own corner through object.setLiveShape {corners, radius}.

This is the part of #1594 that does not change the corner widget drag

Ayberk A. 043b446b94 3D and Materials: the light takes the documented settings
The public 3D and Materials panel options give the Light Settings as
Intensity (0–100 %), Rotation (-180° to 180°), Height (0° to 90°),
Softness (0–100 %) and Ambient Light (0–200 %), with the light moved to
the back or the front of the object. The 3D effects (Revolve included)
had Direction and Elevation (an azimuth and elevation), Intensity and
Ambient (0–100 %).

- Rotation turns the light round the object on the page (our reading:
  0° on its right, counterclockwise); Height raises it from beside the
  object (0°) to straight in front (90°); Light behind the object puts
  it at the back. The light gizmo's ring and line are Rotation and
  Height.
- Softness wraps the light round the object: at 0 % it falls off with
  the angle as before, at 100 % it reaches nothing only straight away.
- Ambient Light runs to 200 %; faces stay no brighter than the art.
- lightRotation, lightHeight, lightBehind and lightSoftness replace
  lightAzimuth and lightElevation. An earlier light is read as the same
  direction, so it shades exactly as before (old and new code give the
  same colours for the four effects and five lights); effect.setParams
  turns a stored one into the new form before applying new values, and
  the parameter description names lightAzimuth and lightElevation as the
  earlier form, so effect.apply and effect.setParams still take them. The
  default light is the earlier default's: Rotation 125.26°, Height 30°.
- The dialog's Lighting tab shows the settings in the documented order;
  Softness, Ambient Light and Light behind the object are in every
  catalog, and the unused Direction, Elevation and Ambient are gone.

Light colour, presets, several lights and shadows are not built.

Ayberk A. 39db6abfce 3D and Materials: Perspective runs 0° to 160°, as documented
The public 3D and Materials panel options give Perspective as 0° to 160°
("how close or far the object appears"); it was a 0–100 % strength, for
Revolve, Extrude & Bevel, Inflate and Rotate alike.

- The eye stands where a sphere about the object's centre, √3 times its
  half size (the box around it fits inside), fills that angle of the
  view: 0° is none, wider brings the eye nearer, and at 160° it is just
  outside the sphere, never inside the object. The documentation doesn't
  say how the angle places the eye; docs/three-d.md says this is our
  reading.
- `perspectiveAngle` (degrees) replaces `perspective` (%). A strength from
  an earlier file or script is read as the angle that shows exactly the
  same view: sin(angle / 2) = √3 × strength / 4, 100 % about 51.3°. An
  angle given too wins. effect.setParams turns a stored strength into the
  angle before applying new values. The parameter description names
  `perspective` as the earlier form, so effect.apply and effect.setParams
  still take it under the key check of #1592. Old and new code draw the four effects identically at 0, 25,
  60 and 100 % (bounds equal to 1e-9).
- The dialogs' Perspective fields run 0–160°.

dotCooCoo 4844d54fda Type: an edit copies a threaded story only when it changes one of its frames
After every edit of a document with threaded text, each frame of a
drag included, threads::reflow copied the runs and the text object of
every frame of every thread, and then dropped the copies for each
thread whose frames the edit had not changed. With a story of 50,000
characters threaded through 8 frames with a style change at every word
(9,618 runs), moving another object took 7.8 ms in a release build,
and a frame of a drag took 7.2 ms.

reflow now copies a thread's story only when one of its frames
changed. The same move takes 0.013 ms, and the drag frame takes
0.012 ms. Threads with a changed frame re-flow as before, and the
documents and undo steps after edits are the same as before.

dotCooCoo 85cea7efea Open: the opening thread also reads linked files and lays out type
When the desktop app opened a document on a thread of its own, that
thread parsed it, but open_read, which the app ran on the UI thread,
read the document's linked files, decoding BMP, PSD and RGB TIFF files
and storing them again as PNG, and laid out the type. In release builds,
a document with 12 linked 3000 x 2000 TIFFs kept the UI thread busy for
1.04 s, and one with 300 Auto Size area type objects, every second one
in three columns, kept it busy for 0.85 s.

read_for_open now reads the linked files and lays out the type on the
opening thread, with the path and the Update Links preference that
opening::start passes it, and open_read only adds the finished document.
open_read now takes 0.02 ms and 0.1 ms on those documents. For the
measured documents, the opened documents, results and undo states are
the same as on main.

dotCooCoo d9bd9b134d Symbols: instances of imported symbols are measured by their art
Every symbol instance was measured as its transform applied to the
20 × 20 square around the origin, which symbols made in the app keep
their art in. The SVG and DXF importers keep symbol art as drawn, so
the box of an instance of an imported symbol did not match its art.
The SVG Star instance at x 20, y 30 draws from (20, 30) to (40, 50)
and was measured from (10, 20) to (30, 40). Align moved such an
instance by the wrong amount, clicks and marquees beside its art
selected it, and the canvas, exports and prints left it out when its
art reached the view or the page and the square did not.

An instance is now measured by its symbol's art, which
Document::symbol_boxes looks up in the document each time
(Node::geometric_bounds_with, visual_bounds_with and
reach_bounds_with). With Use Preview Bounds on, the strokes in the art
count at their own weight, as the canvas draws them, and
object.setBounds counts them at that weight when it sizes an instance
or an object that holds one. When strokes do not scale and a width or
height of 0 or more is smaller than what a path's stroke adds,
object.setBounds now gives the path no width or height, as it does
for an instance whose art has strokes; before, it mirrored the path.
With Use Preview Bounds on, object.setBounds now measures the margins
that strokes add object by object, the members of groups and the
objects in symbol instances' art included, and solves for the width,
height and reference point asked for when the width and height are 0
or more. Before, it measured the margins of the whole selection and
could miss the size or the reference point asked for when strokes did
not scale and the objects' strokes added different margins, and when
strokes scaled and the width and height were out of proportion, even
for one path. A clip group, a Shaper Group, a compound path, type, and
a group or instance with effects or an opacity mask of its own are each
measured as one object, and so is an instance in perspective or one
turned or slanted relative to the bounding box, other than by quarter
turns. When the selection holds more than 4,096 objects to measure this
way, each selected object is measured as one. Instances inside symbol
art are measured by their own symbol's art. An instance is measured as
the square when its symbol is missing, when its symbol or a symbol
nested in its art holds an instance of itself, and when symbols nest 32
deep in its art.

Align and Distribute, the Transform panel, the bounding box and the
selection outline, clicks, the marquee, document.inspect and
document.node, Fit to Artwork Bounds and Fit to Selected Art, canvas
culling, thumbnails, the SVG filter region of an instance with a
raster effect, raster effect images, Export Selection, the SVG of an
artboard, printing, and the PDF, EPS, EMF/WMF and DXF writers use the
new box. The renderer also culls an instance by the effects and
brushed strokes in its art, and it culls a blend, envelope or repeat
by the brush art of what it holds and the effects in the art of the
instances in it. It culls an instance with geometry effects of its own
by the effects in its art after those geometry effects reshape the art.
It measures the effects in a symbol's art once for each symbol and
linear part of the transform that places it. For symbols whose art
holds instances, it measures at most 4,096 placements a frame, and at
most 4,096 more for each pattern tile it rasterizes and each placed
document it draws. Past that, it estimates the reach from the symbol's
reach with no transform, which it measures once. When the drawn
document's symbols change, the renderer drops the cached bounds of the
instances and of the objects that hold them.

The PDF and EPS writers, the SVG of an artboard and Skip Blank
Artboards grow the box of an instance whose art holds brushed strokes
by 16 times the widest stroke (at least 1 pt) of the objects in that
art that have a brushed stroke, plus 8 pt, as the renderer grows the
cull bounds of a brushed path. They keep an instance whose brush art
reaches the page. The SVG of an artboard also keeps an object that
holds an instance when what the canvas paints for it, the effects in
the symbol's art and the instance's own included, reaches the artboard.

Not yet: other commands that measure objects, such as Select › All on
Active Artboard, Transform Each and Convert to Artboards, still measure
an instance by the square.
