File › Open imports .vccomposite files as composite fonts, so an importer
listing that extension no longer shows it under its own filter or in
document.formats. File › Open gets a Composite fonts filter.
document.open refuses dataBase64 that decodes past the importer input
limit before decoding it. A file whose start shows a built-in format
still opens as that format, as it does by path.
Spine::at_length computed tangents from flattened polyline chords, which
are piecewise constant and jump discretely between chords on curved
spines. Steps oriented to the spine with Align to Path stuttered at
large step counts.
Fix: store the original PathData in Spine and compute the tangent from
the original cubic at the true arc-length position via ParamCurveDeriv,
proportionally mapping flattened arc-length s onto each segment's curve
arclength using anchor_length values, instead of using piecewise-constant
chord directions.
Updated segment-selection condition in Spine::at_length to skip segments
whose flattened end is not greater than start before checking whether s is
within the segment. Preserve the existing final-segment fallback so
at_length(0.0) selects a nonzero segment and uses its tangent.
Added zero-derivative fallback tangent for blend-step sampling to keep
Align to Path from passing a zero tangent to atan2.
Added missing docstrings for Spine::new and Spine::length to satisfy
docstring coverage requirements.

Store the original PathData in Spine and compute the tangent from the

Adds a regression test walking 200 samples along a curved spine and
asserting each tangent step stays under 0.1 radians.
SVG export wrote an SVG filter as a live <filter> when its SVG 1.1 form
was at most 64 KB, without counting the region and id it writes into
it. A filter close to the limit came back over it, SVG import dropped
it, and the reopened object had no filter.
Export now leaves room for the id and the measured region, checks the
SVG 1.1 form the way import does, and counts each character past U+00FF
as the character reference Latin-1 output writes. A filter that does not
fit is exported as the other pixel effects are. The SVG 1.1 form and its
check are kept for the filters seen last, as checked filters already
are, so export does not check one filter again for each object.
Type that SVG text can't draw is written as outlines: vertical type, ruby,
right-to-left text, type on a path with an effect other than Rainbow, an end
bracket, Align to Path, Spacing, hanging punctuation, bullets or inline
graphics. Only glyphs bent along a path gave the outlined group a
`role="img"` and `aria-label`; every other case left screen readers and
search with no text. Each of them now names the group with its text.
Convert to Outlines still writes the paths alone, as before.
Inline graphics' placeholder characters stay out of the name, and empty
type gets none. An object whose id is its name also gets `data-name`, so
opening the file again keeps the name instead of taking the label.
Revolve gave each side face a normal as long as its profile edge, and
the mesh kept that length, so the glTF, OBJ and USD files of a revolved
object carried normals of any length (100 for a wall 100 pt tall). A
face whose edge was shorter than about 0.71 pt fell back to its corners'
normal, which turns inward when the profile is drawn the other way, and
its triangles then faced into the solid.
The mesh now scales every given normal to unit length before choosing
between it and the corners' normal.
app.open with params and no importer ran file.open with the path alone, so the desktop app ran the importer on its defaults while headless app.open passed the params to document.open. file.open now carries params to the importer that opens the file.
The importer parameters test installs its module with replace from the second pass on, as plugin.install requires. The permission table in docs/plugins.md lists doc.read for filter, effect and exporter.
An import's instruction and time budgets are now host limits on Limits, as a heavy filter's are, so a test can give an importer a small budget. An importer past its instruction or time limit, and a file past the input limit, return their error and leave an open document and its undo history unchanged. The manifest fuzz varies extensions (missing, dotted, mixed-case, repeated, too long and too many).
A path that keeps its shape because the effect would pass the geometry
budget holds a group's own placed gradients in place. A hidden path in a
layer, which the layer's bounds leave out, no longer holds them, so the
layer's gradient moves with its visible art. The art's own gradients
follow the same rule.
A freeform gradient whose points were edited keeps its vector fitted to
the bounds, so it did not count as placed and its points stayed behind
under a Transform effect and Free Distort unless another placed gradient
was in the same appearance. Its points now move like a placed gradient.
docs/file-format-parity.md held 35 copies of the paragraph under
"Illustrator's private editing data" after #6202 left one, each copy
carrying a different set of the changes merged since. The section now
holds one copy with every clause from the others: placed PDF and .ai
pages as placed documents, Bas Relief among the single-effect art
styles, Bas Relief's settings block in type's art style, the fill a
clipping path keeps with its exceptions, paths with an Art brush, the
spot colors in brush art, symbols defined before the art styles
section, the Type on a Path options, and the artboards the type of a
PDF's later pages goes to.
Align to Path moved the whole line by the largest ascent and descent
among its characters. Each character now moves by its own font, size
and vertical scale. Ascender runs the top of the font's em box along
the path: the ideographic em box that the font's BASE table gives, or
in a Chinese, Japanese or Korean font the one that its typographic or
hhea box, a one-em box-drawing cross or its ideographs give; else an
em box centered on the cap height. Descender runs the bottom of the font's
bounding box along the path, and Center runs a line at half the height
of the top of the font's H along it. In vertical type, Ascender and
Descender move the characters half an em, and Center leaves them on
the path.
Existing documents with Align to Path set to Ascender, Descender or
Center lay their type out at a new distance from the path.
