PDF import turned every function-based shading (ShadingType 1) into a
flat mid-grey. Chromium writes a CSS repeating-linear-gradient this way,
so a red and white hatch came in as a grey bar.
A function-based shading whose colour changes along one axis of its
domain only now becomes a linear gradient across the domain: stops
sampled along that axis, each hard colour change (found by halving the
interval between two samples) two stops at one offset. One whose colour
changes in two directions comes in as its average colour, with a
warning. Either paints only over the shading's domain.

The fit of a thin outline can lose all its area. Its two sides can
straighten onto one line, which leaves two anchors whose segments run
back and forth along it. Or the fit can be a single cubic, which becomes
one anchor and has no segment. Both occur when Flat Logo traces noise
whose cells are one pixel in size. The trace kept such an outline as a
selectable path that paints nothing.
Flat Logo now leaves out an outline whose area is below 1e-6 px^2,
together with its holes, and a hole whose area is below 1e-6 px^2. The
area is summed about the outline's first anchor, as the other trace
modes already do for a filled loop (crates/trace/src/lib.rs:996-1001).
Outlines with an area of 1e-6 px^2 or more, thin slivers included, are
kept as before.
One test traces a black and cream noise with both colors named exactly
and checks that no subpath of the result lacks an area. Two more build
shapes from straight cubics: a hole without area is left out, and an
outline without area is left out with its hole.
Live Paint builds its faces and edges from path outlines alone. Make,
Merge and the Live Paint Bucket put every selected object among the
group's hidden sources, so type, an image, a symbol, a blend or a group
holding one of them vanished from the canvas. They now refuse such a
selection before changing anything ("Live Paint takes paths and compound
paths: convert type, images and other objects to paths first"), as type
and raster images can't go into a Live Paint group directly
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/learn-painting-basics/create-live-paint-groups.html).
One predicate, vectorcraft_tools::builder::live_paint_takes (Live Paint
groups, paths, compound paths and groups of them), decides it for Make,
Merge and the Properties panel's Merge Live Paint, which no longer shows
for a selection Merge refuses. The message has an @msg row in every
catalog.
Tests: tests_build::live_paint_refuses_type_and_images_and_changes_nothing
(Merge, Make and the Bucket with type, an image or a group holding type:
refused, document, selection and undo history unchanged; a group of
paths and a path still merge) and
panels::properties::tests::merge_live_paint_is_a_quick_action_for_a_live_paint_group_and_more
(hidden with type selected). Both fail without the change.

A save (document.save, file.saveAs, file.saveCopy) passes its options to
the export encoders, so an option an encoder refused was reported under
document.export: file.saveCopy with format pdf and range "5" on a
document of three artboards, or with format ai and compress "yes", or
document.save to a .vectorcraft path with compress "yes", failed with
"invalid parameters for `document.export`". The error now names the
save command that was run, for PDF, SVG, .ai, .ait and native files.
document.export's own errors are unchanged.
The tool table in docs/mcp.md listed export and add_text twice. The first
export row omitted the ai format, the per-artboard files of SVG, SVGZ and
EPS, options.useArtboards and options.rect, and said that every format but
PDF writes one artboard. The second add_text row omitted vertical.
Each tool now has one row: export keeps the complete row, and add_text
keeps the row with vertical.

Flat Logo traces a copy of the image at most 1024 pixels on a side,
averaged down by a whole factor, so a 1025-pixel image is traced at
513 pixels. The trace's warnings did not say so, because they compared
the image only with the decoded raster. For an image over 1500 pixels
they said instead that it is traced more slowly, which Flat Logo does
not do.
The trace result now carries Flat Logo's working size when it averaged
the image down. imageTrace.make and imageTrace.makeAndExpand then name
both sizes in their warnings, and the status bar shows that note, in
place of the slower-trace and megapixel notes. Other modes keep their
warnings. The message has a row in each catalog that translates the
other Image Trace warnings.
The Properties panel has the additional contextual controls the public
Properties panel overview lists
(https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/properties-panel-overview.html),
each running the existing command:
- Quick Actions: Blend Options for one selected blend while the Blend
tool is in use (the Blend Options dialog; OK is one undo step), and
Merge Live Paint when a Live Paint group is selected with more objects
(livePaint.merge).
- Appearance: the stroke's Variable Width Profile list (the Control
bar's) with the Width tool or when the stroke has a variable width
(stroke.set {profile}); beside fx, with one effect on the one selected
object (its own, or a fill's or stroke's), its name and a Delete icon
that removes it (effect.remove); with several, the icon opens the
Appearance panel, as the overview describes.
- With Direct Selection and corners of one path selected, Corner and
Corner Radius set those corners' kind and radius
(object.setLiveShape); a live rectangle's and polygon's own rows
already do, so they get no second row.
The overview's Variable Font icon was already in Character. Every label
is already in every catalog.

A native save was pretty-printed when the document had at most 2,000
layers and objects and its compact JSON was at most 1 MiB. Pretty
printing puts every coordinate on its own indented line, so traced art
with few paths and many anchors could pass that check and be written at
about five times the size of its compact JSON.
The 1 MiB limit now applies to the pretty-printed document, indented as
the file holds it and in the form the save writes: version 1 anchors,
and placed documents expanded for older versions or Include Linked
Files. Documents whose pretty-printed JSON is over 1 MiB are saved as
compact JSON, even when their compact JSON is under it. The 2,000-object
rule and compressed saves are unchanged. docs/mcp.md describes the rule.
The Image Trace panel had no way to compare a trace with its source
image except changing View and changing it back.
The panel now has an eye button to the right of View, enabled with an
Image Trace object selected. While it is held down, the canvas draws the
selected Image Trace objects with their source image, whatever their
View, and draws their View again on release. The document, its View and
the undo history are unchanged. The renderer takes the objects in
RenderOptions::trace_source, which is also part of the canvas frame key
and the raster-effect cache key.
With type written as text, PDF export drew the hyphen that ends a line
broken inside a word as a path. The file's text had no hyphen where the
canvas draws one, so copied or searched text read "considerations"
where the line shows "con-".
The hyphen is now written as text where the line draws it, as the
character the font gives its glyph to: "-", or U+2010 when the font
gives the glyph to U+2010 and not to "-". It is a text run of its own,
and right-to-left lines keep their /ReversedChars marking. The invisible
text of type without paint holds the hyphens too. Kashidas and list
markers are still drawn as paths.
Docs: docs/mcp.md, docs/target-app-parity.md.
The PencilStraight entry in cursors.toml now says the cursor does not
show while Alt is also held with Alt key toggles to Smooth Tool on, and
that the line follows 45° steps from the Constrain Angle. The parity doc
says the Option/Alt straight line waits for #3959.
With Shift held before a press, the Pencil now shows a new cursor,
PencilStraight: its crosshair with a short straight line where the
closing cursor has its ring. The cursor follows the rule the press uses
to start a straight line, so it shows exactly when the press draws one.
With Alt key toggles to Smooth Tool on and Alt held too, the Smooth
cursor shows as before. Once the press is down, and with the
Paintbrush, Shift leaves the tool's own cursor. Use Precise Cursors
turns the new cursor into the plain crosshair.
Draw straight lines with the Pencil tool describes a straight-line icon
on the Pencil while Shift or Alt is held:
