Offset Path took each selected path in turn, so offsetting many paths, or a
group of many paths, used one CPU. It now reads the selected paths first,
works out their offsets on as many threads as the computer has logical CPUs
(one thread on the web and for a single path), and then makes the new
objects one after another in the selection's order on the editing thread.
The new objects, their ids, their stacking, the selection, the messages and
the undo step are the same as before. When several paths fail, the error is
the one for the first of them in the selection's order, and the paths after
a failure that have not started yet are skipped.
Ruler guides were a list kept beside the layers. Each guide is now an
object of its layer or sublayer, always directly in it and above the
layer's art. These behave as on main:
- Guides draw on screen only. Exports (SVG, PDF, PNG, PSD), Fit All,
Select All, the art bounds, clicks and marquees, and a layer's
Pathfinder and Transform effects leave them out. The Layers panel
lists them as guide rows of their layer, the highest guide.list
index first.
- Deleting a layer deletes its guides, and merging layers keeps their
guides in the merged layer.
- The guide commands number guides as guide.list does, in the order
they were made.
New: each guide takes an id from the document's object ids. An object
command given a guide's id fails with an error, and node.move cannot
put a guide into a group or out of its layers. A guide made while an
opacity mask, a symbol or a pattern is edited moves to the top
visible, unlocked layer when editing ends.
File format: native files still save the guides in the document's
guides list, in every file version, so older builds read them. Each
entry may now also carry the guide's id, name, locked and hidden
flags; older builds ignore those fields. Opening a file puts each
saved guide on its layer (on the top visible, unlocked layer when the
file names none or a layer it does not have), and each saved guide
counts against the object limit for opening a file. A ruler guide node
that a file holds below a layer's art moves up to the layer's guides,
and one anywhere else (in a group or another object, beside the
layers, or in a symbol) is removed. Ruler guides read from an .ai file
become guide objects on the layer they were on, numbered in the order
the file lists them.
text.setStyle now reads `size` and `tracking` with `number_given` and
`length_given` from pathops.rs instead of its own copies.
Both helpers read a string only when all of it is a number, or for
`length_given` a length with a unit (`"5 mm"`). Before, `"20abc"` read
as 20, so `text.setStyle` applied a 20 pt size and Offset Path a 10 pt
offset for `"10abc"`. Such a string is now refused with "`size` must be
a number, not \"20abc\"" and the document is left as it was.
object.path.offsetPath, object.path.simplify, object.path.splitIntoGrid,
object.path.cleanUp, object.pathfinder.trap and addon.contour.set read
their params with helpers that fell back to the default for a value of
the wrong type: "offset": true offset by 10 pt, "joins": 3 gave mitered
joins, "addGuides": "yes" added no guides. Each such value is now an
error naming the param, and the document and the undo history stay as
they were. An omitted or null param keeps its default, and a distance
still takes a string with a unit ("5 mm"). An unknown `joins` name is
refused as well.
Offset Path outlined an open path on both sides, so a shape whose last
anchor sits on its first came out as a ring with a hole. Such a path is
now offset as a closed shape: its last anchor merges into its first,
which takes the last anchor's in-handle, with the same 1e-6 test that
Object › Path › Join uses for one path (crates/engine/src/cmd/path.rs).
The Offset Path effect calls the same function.
