Create Gradient Mesh, a Mesh tool click and Object > Expand of a gradient
to a mesh gave each border edge one cubic fitted between two mesh points
and picked the corners from the bounding box, so the border cut off
corners and curves: 49 pt off a five-point star, 54 pt off a notch.
- The border follows the outline of the largest subpath by length; border
points sit on it and an edge with no anchor inside is the exact piece
of its segment.
- Where no single cubic follows a run within 0.1 pt (a thousandth of the
size on a small outline), a mesh line goes through an anchor, the
sharpest corner first; at most 256 lines each way. Rectangles and
ellipses keep the rows and columns asked for.
- Smooth runs keep their end tangents; border handles are no longer made
collinear.
- To Center and To Edge highlight placement accounts for the extra lines
(for_path_shaded, also used for gradient fills).
- Non-finite points give no mesh; a degenerate outline keeps the old
bounding-box mesh.
Holes of a compound path are still left out, as before.

A top-object envelope splits its outline into four sides at four corners
and maps the content onto the Coons patch of those sides. The sides
shared out the content by length, and the corners were the anchors or
curve points nearest the bounding box corners.
Each piece of a side between anchors and corners now takes a share of the
content's width or height in proportion to the length of its control
polygon, spread along the piece by its curve parameter. A straight
segment spreads it evenly by length. A rounded rectangle stays close to
the identity, and the content follows the curves of a side whose segments
differ in size.
Each corner is now the nearest anchor to its bounding box corner among
the sharp anchors that point out of the outline and lie within 47.5% of
the box's width and height from that corner. A handle shorter than
0.01 pt, or tangent unit vectors that differ by 0.01 or more in x or y,
makes an anchor sharp, and the first one along the outline wins a tie.
Without such an anchor, the corner is the outline's nearest point to the
box corner, moved onto the end anchor of its segment within 0.5% of the
segment's parameter. Envelopes opened from .ai files keep the corners the
file saves.
These are VectorCraft's own rules. Existing top-object envelopes redraw by
them. Gradient meshes made from a path keep their sides measured by length.
- crates/doc/src/live/mesh.rs: Coons::from_top_object and the corner
search, used for top-object envelopes.
- EnvelopeKind::TopObject gains an optional `corners` field (anchor
indices); the .ai importer fills it from the mesh's corners.
- Params text of object.envelope.makeWithTopObject, docs/mcp.md
(Envelopes) and a progress line in docs/target-app-parity.md.
An envelope mapped type from its laid-out box: ascent to descent for
point type, the frame for area type. The distorted glyphs then filled
less of the envelope than other art does, with room above the capitals
and below the baseline.
The envelope now maps type from the bounds of its glyph outlines,
underlines and strikethroughs when the type is on its own, in groups
and layers, or used as a clipping path. Inline graphics count by their
boxes. Rotated type and type in perspective map from their outlines as
they are drawn. Make with Mesh,
Make with Top Object and Reset with Mesh without Maintain Shape use
those bounds. Type that draws nothing keeps its laid-out box, and so
does type inside any other object, such as a blend, a repeat or a
symbol instance. Shrink Text to Fit type is measured as it is laid out
on the page.
vectorcraft-text's envelope_ink measures the type, and
register_envelope_ink registers it with the document crate. The engine
session, Renderer::new, live evaluation in vectorcraft-effects and the
.ai reader register it. The document crate keeps the measured boxes per
thread, by object and by a hash of the content, and measures again when
the type, the fonts, the hyphenation exceptions or the transform's
scale or rotation change.
This is VectorCraft's own rule. Envelopes of type made in VectorCraft
and in saved files map from the glyph outline bounds instead of the
type's laid-out box, so they redraw differently.
Commands that read `id` and otherwise act on the selection, the highlighted
layer row or a new object read it with a lenient helper, so `{"id": "abc"}`,
`true` or `{}` acted on the selection instead. They now read it with
`object_param`, which refuses any value that is not a non-negative integer
with "`id` must be a whole number" under the command's name and changes
nothing; an omitted or null `id` keeps the default.
Commands: object.isolate, layer.locate, layer.releaseToLayers,
graphicStyle.new and redefine, charStyle and paraStyle new, apply and
redefine, image.info, links.info, links.goTo, links.unembed, shaper.release,
shaper.expand (whose errors now carry their own name),
transparency.editOpacityMask, transparency.viewOpacityMask, symbol.edit, the
object.blend.spine commands, path.curvature and the type commands that read
type ranges.
object.envelope.makeWithWarp, resetWithWarp and options read `style`
and `orientation`, and options read `preserveShape`, as text and
ignored any other value, so `{"style": 5}` kept the default style and
`{"orientation": "diagonal"}` kept the current orientation. They now
return "`style` must be a string" or "`preserveShape` must be a
string" for a value other than text or null, and "`orientation` must
be one of horizontal, vertical" for any other orientation, through
the shared `choice` helper. object.envelope.options checks the warp
keys whatever is selected, so a call with no envelope or only mesh
envelopes selected gets the same errors, an unknown style name
included. Omitted and null values keep today's defaults.
Docs: docs/mcp.md, docs/target-app-parity.md.
When Distort Appearance is on and the size a `.ai` saves for an
envelope's contents (`AIDeformArtWidthKey`, `AIDeformArtHeightKey`)
matches the contents' bounds with strokes, the reader now maps the
contents from that stroked box. It used to map them from the geometric
bounds, half a stroke inside that box, so an envelope of stroked art
could differ from its drawn art and keep the drawn art with a note.
Envelope Options hold the box's margins as `boundsMargin`, shares of the
geometric bounds at the top, bottom, left and right. Native files write
them only when they are not zero, and `object.envelope.info` reports
them then. Leaving Edit Contents measures them again when the strokes
reach differently than when Edit Contents began, and the node holds
what they measured then until it leaves. New envelopes have no
margins, so their results do not change. Contents with no width or no
height, such as one straight line, get no margins.
Docs: docs/mcp.md, docs/target-app-parity.md.
object.blend.spine.moveAnchor now refuses any supplied `with` (even an
empty list) together with `handle`. Direct Selection builds the blend
spine once when drawing the picked points and once per drag preview,
instead of once per picked point. Part of #5285.
Direct Selection kept only one picked point of a blend's spine. Shift-click
now adds a point of the same spine or takes it away, and dragging any picked
point moves them all. object.blend.spine.moveAnchor takes `with`, the other
points to move by as much, with the key objects on them, in one undo step.
Commands whose `id` or `ids` the shared check in Session::execute does not
read still parsed them with id_param/ids_param, which drop anything that is
not a non-negative integer, and then acted on the selection or the current
layer. `object.blend.make {"ids": 3}` blended the selection,
`object.envelope.makeWithWarp {"ids": [2, "x"]}` warped the selection,
`graph.setData {"id": "2"}` changed the selected graph and
`layer.newSublayer {"parent": "2"}` added a sublayer to the current layer.
- cmd::named_ids and cmd::named_id read `ids`/`id` as targets does: a value
that is not an object id, or an unresolved step reference, is an error.
- The symbol and brush, Live Paint, Shape Builder and Image Trace, blend,
envelope and mesh, perspective, Liquify, Puppet Warp and graph helpers use
them in place of the lenient readers.
- layer.clippingMask.toggle checks `id`, and layer.newSublayer checks
`parent`, with checked_id before falling back to the highlighted row or the
current layer.
object.mesh.create with `at` ignored a failed line placement and still replaced the
path with a bare 1x1 mesh. When the new mesh can't place its lines at the point, the
object is left as it is, and when nothing was converted the command fails with
"point is outside the object" and adds no undo step.
A Mesh tool click within the hit tolerance outside a gradient mesh hit the
mesh, but object.mesh.addLine looked for the point inside the outline only
and failed with "point is outside the mesh". The same click on a path's edge
made a 1x1 mesh without the line.
- GradientMesh::locate_within takes a tolerance: a point outside the mesh
within it of the outline gives the nearest point of the edge.
- object.mesh.addLine and object.mesh.create take an optional `tolerance`
(0 by default), and the Mesh tool sends its hit tolerance.
