text.create, text.createInPath, text.setText and text.setStyle answer with
overflow: [id…] for the area type and type on a path whose text doesn't fit (left
out when all fits), and MCP add_text with overflow: true. add_text takes area
type's fit and fitMinPercent.
File > Place, Relink and Open refused a grayscale TIFF whose pixels carry an alpha channel or
another extra channel: the image decoder reads neither. They are now read like CMYK TIFFs with
alpha: the first extra sample is the transparency when the file says it is alpha (associated alpha
divided back out), and other channels are left out.
Object > Path > Split Into Grid took a number of rows and columns and one gutter, and split each
selected path on its own. The dialog now has the documented options, the rows beside the columns:
number, height or width, gutter and total, with Add Guides and Preview. Several selected paths
become one grid over them all, painted as the topmost one, as documented.
object.path.splitIntoGrid takes rowGutter and columnGutter (gutter still sets both), totalHeight
and totalWidth, height and width (the size of each row and column, which sets the total) and
addGuides, which adds ruler guides along the row and column edges on the grid's layer.

On each pointer move of an Alt-drag with the Selection, Direct
Selection, Group Selection, Rotate, Scale, Reflect or Shear tool,
Session::preview put the drag's snapshot back and ran object.transform
with copy again, and duplicate_in copied every selected object again.
The Move, Rotate, Scale, Reflect and Shear dialogs with Copy and Preview
on copied every selected object again on each change of a value.
The interaction now keeps the untransformed copies that its first
preview with copy makes of the snapshot. Each later preview that
copies the same objects of the same snapshot transforms only those
copies. The copies keep their ids, and the document, the selection,
the undo step and the journal are the same as before. With 25,000
rectangles selected, a release build of vectorcraft-cli took a median
of 138.5 ms for each Alt-drag move after the first preview and takes
105.7 ms with this change.

The three 3D types besides Revolve, as live effects in the three-d crate,
drawn as shaded vector faces by the canvas, SVG/PDF export and Expand
Appearance alike, from the public 3D and Materials documentation:
- Extrude & Bevel: depth (0-2000 pt), twist, taper, solid or hollow caps,
and bevels in six original cross-sections (classic, rounded, cove, step,
ogee) with width, height, repeat, spacing, inside and both sides.
- Inflate: the shape as a membrane under pressure (a Poisson solve held at
zero along the outline and holes), so it rises vertically from the edge
and rounds without creases; volume, depth and both sides. Steep cells
near the outline are refined without cracks.
- Rotate: every fill and stroke turned in 3D and shaded as one plane.
All three share Revolve's view and lighting parameters, the rotation and
light gizmos (turning about the art's centre) and a dialog with Object,
Rotation and Lighting tabs, with Position presets (Front ... Isometric
Bottom, our own values). An object takes one 3D effect. Inflate cuts the
grid cells that straddle a hole's edge with pathops, hence the new
pathops -> three-d layer order.
Docs: docs/three-d.md, mcp.md, and the 3D rows of the parity docs.
The renderer kept the rasters of an object's drop shadows, outer glows
and filtered content (Gaussian Blur, Feather and the Photoshop-style
filters), and drew them again while the object, the zoom and rotation
and the ink plane stayed the same. The content drawn into a raster also
reads things outside the object: patterns, symbols, brushes, images,
document, layer and color settings, the knockout a group inherits, the
fonts, and the options the frame is drawn with. When one of them
changed, a renderer that had drawn the object went on drawing the
raster it had kept, made from the old values.
Each kept raster now records what its content was drawn from: which of
those things the object reads, found by walking the object when the
raster is made, and a hash of their values then. The renderer draws
the raster only while that hash is the same in the current frame. Once
a frame, the renderer hashes the document's patterns, symbols and
images. It hashes their art and pixels by the addresses of their
shared values, and it keeps weak references to those values while a
raster made with them is kept, so no other value can take one of those
addresses. A filtered raster also records the color channels its
filters split, and under De-Interlace the raster resolution.
A temporary release test timed the inputs of 400 kept rasters at about
10 microseconds a frame.
Opening an EPS whose threaded area type frame has a control point at
x = 8e115 failed with an internal error ("capacity overflow").
`eps_text_frames_never_panic` in `import_fuzz` found it with
PROPTEST_CASES=20000. Text layout flattens a frame to within 0.1 pt,
and for such a curve kurbo 0.13.1's `flatten` calls `reserve` for
`usize::MAX` quadratic pieces. Laying out text around a wrap shape with
such a curve failed the same way. Laying out type on a path along such
a curve panicked in kurbo's `solve_itp` ("attempt to shift left with
overflow") in builds with overflow checks, and in a release build it
did not finish within 20 s. Laying out area type in a triangle frame
that comes to a point at its top, at y = 1e20, did not finish either:
adding a lead to a baseline that large leaves the baseline where it is.
Text layout now leaves out a frame, a text wrap shape or the path of
type on a path that has a coordinate beyond 1,000,000,000 pt either
way, control points included, or a NaN coordinate in an anchor point.
Such a frame or path holds no text, and such a wrap shape is ignored.
PDF export uses the same bound (`MAX_COORD` in
`crates/pdf/src/export.rs`).
Text layout also steps a line down a frame cell at most 100,000 times
to find room for it. In a cell taller than 100,000 leads, a step is the
cell's height divided by 100,000; in a shorter cell, a step is one
lead, as before. Before this change, in a dev build, with triangle
frames that come to a point at their top, laying out text in one
2,000,000,000 pt tall took 9.8 s, and laying out a paragraph whose
Space Before is -1e300 pt in one 1,000 pt tall did not finish within
20 s.
The layout drops lines that overflow an area frame vertically, so counting
the first paragraph's laid-out lines cannot see a wrapped second line
when the frame holds only one. The bisection then found every tracking
"one line" and ran to its 2000 ceiling, which spread the line far past the
frame (most glyphs clipped away) while the command reported success.
one_line now asks whether the first line reaches the end of the first
paragraph, which holds regardless of dropped overflow lines. Regression
test: area 240x50 at size 36 previously returned tracking 1999.9, now
fills the width (avail - w < 5) with the paragraph on one line.
Delete, Cut, Group, Make Compound Path, Make Clipping Mask, Send to
Current Layer, Ungroup and Release Compound Path removed, inserted or
moved one object at a time. duplicate_in inserted one copy at a time;
Duplicate, Copy in the Move, Rotate, Scale, Reflect and Shear dialogs,
Transform Again after a copy, Transform Each with Copy, the perspective
copies and each move of an Alt-drag call it. Each insertion or removal
moved the later objects of the same layer or group to other indices.
The next lookup by id then walked the tree, and after every fourth such
walk Document::index_path rebuilt the whole lookup cache. Each command
did work that grew with the number of objects times the size of the
document: with 25,000 rectangles selected, a release build of
vectorcraft-cli took 7.2 s to group them and 11.5 s to copy them with
object.transform.
Document::remove_many, Document::wrap and Document::insert_beside
remove nodes, wrap them in a new node, or put nodes directly above or
in place of their anchors, in one pass over the children of each
parent. Each finds the nodes with one index_paths call, checks every id
before it changes anything, and clears the lookup cache once. The
commands above use them. The objects keep their order, the copies take
their ids in the same order, and the selection, the undo step and the
journal are the same. duplicate_in still copies one root at a time when
a root is listed twice or lies inside another root. A release build
with this change groups the 25,000 rectangles in 27 ms and copies them
in 121 ms.
Docs: docs/target-app-parity.md.
With Double Click To Isolate on, the Selection tool isolated groups only. A
double-click on a single path, compound path, image, mesh or placed file now
isolates it too, as the public documentation describes. Type still switches to
the Type tool; blends, envelopes, repeats and symbol instances keep their own
editing modes.
While a single object is isolated only it is hit, marqueed and taken by Select
All, new art goes beside it in its group or layer, and a double-click on the
empty canvas leaves with it selected. object.isolate accepts any object except
type.
- The type in a text object's drawn look (1 /FreeUndo) is a story of the
undo-free text document, which counts its stories on its own. It was read
as the story of that number in the text document, so a label could show
another object's text in another object's frame. The object itself, which
follows the look, is the type now.
- The page's type of a text object on a hidden layer stays with that object
(hidden) instead of going to the nearest text object that shows.
- The type on the page of a later artboard is matched where the layers have
that artboard, not by the first page's place.
The editing data places a gradient with matrices after Bg: Xm for a linear
gradient's whole ramp and one Bm for each pair of stops next to each other.
The reader kept the last Bm, so a gradient of three stops drew only its last
part. It now uses Xm (or, without one, the span of the Bm's from the first
stop to the last), and a radial gradient's one Bm as before. The angle and
length are in the matrices, so Bg's own numbers are used only without them.
An object's own note of its gradient after it (Bb, Bg, BB with no path) no
longer becomes the fill of the next path.
A .ai file with placed files opened from its PDF part (no guides, no sublayers,
no hidden objects), because the editing-data reader stopped at them.
- Lexer: a placed file's preview section is one token (it was skipped).
- Reader: %AI5_BeginPlace ... ~ becomes a linked image with the file's path,
showing the preview the data keeps of it (premultiplied ARGB, capped at
MAX_PIXELS, its rows checked against the bytes there), in its place: the
matrix takes the file's pixels from the canvas, where they start at the point
of art space's origin. A placed file without a preview, a path or a matrix
still makes the file open from its PDF part.
- The open result lists one warning saying linked pictures show the
low-resolution preview until their files are found (rows in the catalogs).
- Engine: a link nothing is known of whose image shows a preview is read where
it is found as the document opens, into the image's bounds, and isn't
reported as modified.
- Tests: lexer, reader (hand-written data), engine open with the link missing
and found, fuzz tokens.
- Docs: file-format-parity, target-app-parity, gaps, ROADMAP.
A PDF-compatible .ai opens on its trim boxes, its editor's artboards,
with the bleed boxes round them as the document's bleed (#1349). A PDF
saved with its editing data (#1345) keeps that data under
AIPDFPrivateData keys, which has_illustrator_data didn't look for, so
such a PDF with a bleed still opened on its crop box: the artboard took
the bleed in and the editing data was refused as being for a different
page. has_illustrator_data now finds either key. has_private_data, which
also decides how a page is clipped, is unchanged.
Test: a_file_with_a_bleed_opens_on_its_artboard_with_the_bleed_round_it
(the .ai case, and the same hand-written file with AIPDFPrivateData).
A background drawn at the artboard's own position could sit 3e-14 pt outside it and
stay behind when the artboard moved, was copied or scaled its art. Art within a
millionth of a point of the artboard's edges now counts as inside it.
The fix and both tests are from #1295 by Luca Lorenz, without its change to art that
only partly overlaps the artboard.

Unlocked rectangle corners now each use their own radius and type (top left,
top right, bottom right, bottom left) instead of all following the first one,
and straight corners are cut across instead of rounded. patchy-shapes.af now
matches its embedded thumbnail (mean difference 1.91 -> 0.24) with no warning.

In builds with overflow checks (`cargo run`, `cargo test` and
`cargo xtask ci`), PDF export aborted the process when a number it
wrote rounded to -2,147,483,648 as an f32. pdf-writer 0.15 writes
-2,147,483,648.0 as an integer, and `Limits::register_int` overflows
when it takes the absolute value. krilla 0.8.2's `Surface` then fails
an assertion in its `Drop` while that panic unwinds.
`svg_hostile_markup_never_panics` in `import_fuzz` hit it with type
shifted 2,147,483,649 pt down. Paths, gradients, dash offsets, images
and artboards that far out hit it too, and so does a group around a
stroke wide enough to reach that far. Release builds have no overflow
checks.
PDF export now leaves out art whose coordinates or transform entries
lie beyond 1,000,000,000 in its own space or in the content stream it
is drawn into, and glyph lines whose spacing lies beyond 1,000,000,000
thousandths of an em. That covers paths and clipping paths, glyph
lines, images, gradients, strokes whose width, caps or miter spikes
reach that far, and the art and marks of a page whose artboard lies
that far, which is written blank. A dash offset beyond the bound is
written as its remainder after whole periods of the pattern.
The type's transform is now pushed inside the form that marks a fill
or stroke of type to overprint. The exporter checks what that form
holds through the type's transform, as it checks the same fill or
stroke without overprint.
With anchors of one path direct-selected and another object selected
whole, the arrow keys (object.nudge), path.moveAnchors and a Direct
Selection drag of the selected anchors moved that object without its
pattern tiles, whatever General › Transform Pattern Tiles was set to.
When the same object was selected on its own, the arrow keys and a
Direct Selection drag followed the preference. path.moveAnchors left
the tiles in place in that case too.
path.moveAnchors now follows the preference for the objects it moves
whole, as the transforms, Align and Distribute do. path.moveAnchors
and object.nudge also take a `patterns` param for one call. When those
objects use a pattern, the journal records the choice, and a recorded
action plays back with it. Partly selected paths still move only their
selected anchors.
Docs: docs/mcp.md (transformPatternTiles), docs/target-app-parity.md.
These commands moved selected objects into a hidden or locked layer,
or hid them, and left them selected, with the key object still set
when it was one of them:
- a row dragged into a hidden layer or group (layer.move);
- node.move into a hidden or locked layer or group;
- Merge Selected into a hidden or locked layer;
- Flatten Artwork into a locked layer;
- Collect in New Layer, when the topmost row it collects is in a
hidden or locked layer;
- applying a data set that hides bound objects (dataset.select,
dataset.next, dataset.prev).
They now call Selection::deselect_uneditable after the change, as
layer.setProps, layer.hideOthers and layer.lockOthers do. Every
selected object left hidden or locked is deselected, and the key
object is cleared when it is one of them. Undo restores the objects
and selects them again with the key object. A row drag into a hidden
layer and node.move into a hidden or locked layer still succeed. The
params text of layer.move, node.move, layer.merge, layer.flatten,
layer.collectInNew and dataset.select describes the deselection.
The Layers panel section of docs/mcp.md said that node.move has the
same rules as layer.move; it now says that node.move also moves a row
into a locked layer or group, which layer.move refuses.
Docs: docs/mcp.md, docs/target-app-parity.md.
A PDF saved with the reference app's editing data keeps that data in
streams named AIPDFPrivateData1, AIPDFPrivateData2, ..., where a .ai
file uses AIPrivateData1, AIPrivateData2, .... illustrator_data read
only the .ai names, so such a PDF opened like any other PDF: plain
groups opened ungrouped, and hidden objects and guides were missing. The
import gave no warning that the PDF's editing data went unread.
illustrator_data now reads the AIPDFPrivateData streams when the file
has no AIPrivateData1, and the PDF opens from its editing data as a .ai
file does. editingData: false still opens it like any other PDF.
has_private_data still looks for AIPrivateData keys only.
layered_ai also returns whether it read the layers. When it did, art
reaching past a PDF's page opens whole, and through_editing_data drops
the PDF importer's note that such art was clipped (PAST_PAGE_NOTE, now
public) as it drops the off-artboard note. When it didn't, both notes
stay. On main, a .ai whose editing data can't be decoded or has no
layers opened from its PDF part without the off-artboard note.
testkit::ai::pdf writes the .ai file of testkit::ai::ai with the PDF
key names. The editing-data tests open it as a PDF, and the import fuzz
test opens the damaged sample as a PDF too.
Docs: the document.open params, docs/mcp.md,
docs/file-format-parity.md, docs/gaps.md (G9: the export direction of
#868 remains), one evidence line in docs/target-app-parity.md, and #868
moved from layer structure to editing data in the File formats row of
docs/target-app-parity.md and in docs/roadmap.md.
A PDF-compatible .ai with a bleed writes its PDF part's page as the
artboard grown by the bleed: the crop box takes the bleed in, the trim
box is the artboard and the bleed box the bleed. The importer made the
crop box the artboard, so the bleed opened as more white page with no
bleed guide; and since the editing data's artboard no longer matched
that page, its layers weren't read either ("its editing data is for a
different page").
Opening a PDF-compatible .ai with the crop box (the default) now takes
its trim boxes as the artboards. Any import on the trim boxes (Crop To
› Trim, for a PDF too) sets the document's bleed to how far the bleed
boxes reach past them on each side (ISO 32000-1, 14.11.2), kept to
0–72 pt, and the document read from the editing data keeps it. Art in
the bleed shows outside the artboard, within the bleed guide. Plain
PDFs still open on their crop box by default, and Place is unchanged.

A PDF, and the PDF part of a PDF-compatible .ai, writes a shape filled
with a gradient as a clip followed by a shading fill: the shape, W n,
then sh, which fills the clip's bounds. The importer kept that as a
clip group of the shape (a clipping path) and a rectangle the size of
its bounds filled with the gradient. The Shape Builder skips clipping
paths, so it built its pieces from the rectangles: two overlapping
gradient-filled diamonds gave three rectangles. The Fill swatch showed
? for such a selection, since it held groups.
A clip whose only content is one rectangle covering the clip, filled
with a gradient placed on the page and nothing else, now comes in as
one path: the clip's outline, its subpaths closed, with the
rectangle's fill, opacity, blend mode and mask. It draws as before and
edits like a gradient-filled path drawn in the app. Clips holding
anything else (a flat colour, several objects, a gradient that doesn't
cover the clip, a shading that doesn't extend past its ends) stay clip
groups.
Tests: a diamond clipping a shading imports as one closed path of four
anchors with the linear gradient where it was, and a gradient covering
only part of the diamond or a flat colour stay clipped. Two overlapping
diamonds in a hand-written PDF, clicked on their overlap with the Shape
Builder, give what is left of each (9000 pt² each) and the overlap
diamond (3000 pt²), each with its gradient; main gave three rectangles
of 12000 pt².

The details name the copy's images, so the new document written before them paired with the old
details lost the images placed since the last copy (and a first copy lost all of them). Until the
new document is in, the details name the old and the new images.
Save serializes JSON straight into the compressor and writes images from their Arc into the
file; open reads each image into its own buffer, and NodeKind reads its tag first instead of
buffering every node. Already-compressed images are stored rather than deflated again in the
same gzip stream. Limits apply per section, so any file VectorCraft writes opens again. Data
Recovery writes each image once, content-addressed, instead of every interval. Native files open
on a background thread. Files stay readable by main both ways; JSON-only saves are identical.
