Convert to Artboards found the highest artboard id twice for each object it
converted: once for the new artboard's name and once in
Document::next_artboard_id. Converting N objects read about N^2 artboards.
The command now keeps the highest id as it adds artboards, and
Document::next_artboard_id_above gives the next id from it. When an artboard
has id u32::MAX, it falls back to next_artboard_id, which takes the smallest
free id. The ids and names it gives are unchanged.
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.
Measure Type by Glyph Bounds (`typeGlyphBounds`, off by default) is in
Preferences > Type > Glyph Bounds and the Transform panel menu. With it
on, the bounding box, the Transform, Control bar and Properties X, Y, W
and H, `object.setBounds`, the transform tools' reference point and the
Arrange commands measure point type selected on its own by the ink of
its glyphs instead of its em box. A typed W or H scales the live type
until its ink has that size.
- The engine caches each type object's ink in text space with its
layout bounds; the cache is not saved.
- Use Preview Bounds adds the characters' strokes, and type with
geometry effects is measured as drawn. Skewed type is measured by its
outlines.
- Type that draws nothing, area type, type on a path and type inside a
selected group are measured as before. Align and Distribute keep
following Align to Glyph Bounds.

object.setBounds params text.
A paste relinked every copy to the document's resources even when no
resource had another name or color and the objects linked no graphic
style. It now leaves those copies as they are.
Finding the pasted type looked each id up and compared every text object
with the ones already found. Text commands and the bounds refresh after
a paste now look all ids up in one walk and keep the found ids in a set.
Giving a pasted group new ids builds its map of old to new ids only for
an Objects on Path group, which is the only kind that reads it.
A pasted solid paint with no swatch link and a tint other than 1 now
keeps that tint when no relinking runs. Saved art carries a tint of 1 on
such a paint.
The enabled check of artboard.deleteEmpty built the full list of empty
artboards, measuring the visual bounds of the art against every
artboard, each time the Artboards panel menu was drawn. It now returns
false at once in a document with one artboard (that artboard is never
deleted). With two or more, it asks the new
Document::any_artboard_without_art whether any unlocked artboard has no
art, which is the same answer as a non-empty list.
Document::any_artboard_without_art builds the symbol boxes once for all
the artboards and first tests each path and compound path by a quick
box: its control points' box grown by the farthest its strokes reach
(Appearance::outset), with a margin for rounding. An artboard that no
quick box meets is reported empty without measuring along any path.
Only when every artboard may hold art is each one measured.
Document::artboard_has_art also skips measuring an object whose quick
box misses the artboard; its answers are unchanged.
The check of gradient.presets.save found the proxy paints through
Node::proxy_paint, which measures the object's geometric bounds for a
gradient box the check does not use. Node::proxy_paint_only picks the
same paint without measuring, and the engine's proxy_paint uses it, so
the Fill and Stroke proxies and the mixed-paint test no longer measure
each object either.
With an open stroked path of 200,000 anchors selected, the two checks
take under 0.01 ms instead of 21.9 ms and 17.2 ms in a release build, and
Delete Empty Artboards' check takes 0.85 ms instead of 42.1 ms with a
second, empty artboard.
Tests compare each check with what its command does (one artboard, all
empty, one empty, locked empty, nested art; with and without a
gradient), compare any_empty_artboards with the previous check and with
measuring every object on 120 seeded documents, compare the quick boxes
with the visual bounds on seeded strokes, and compare proxy_paint_only
with proxy_paint on seeded objects.
