A new gradient kind, `diamond`, runs its stops from the center (the
start) out to a square with a corner at the end of the vector; the
aspect stretches the square across the vector into a rhombus. The
Gradient panel's Type row has a Diamond button, the Gradient tool draws
the square with the aspect handle and center ring, and a gradient
fitted to an object covers its box.
- Model and canvas: the level is |x| + |y| in the square's frame; a
square with no area (no vector, an aspect of 0, numbers out of range)
paints the last stop. The canvas draws it as pixels, out to a
stroke's miters, caps and arrowheads. Transforms keep the vector and
take the mapped size across it as the aspect.
- Commands: `paint.setFill`, `paint.editGradient` and
`paint.setGradientGeom` take `kind: "diamond"`; a negative aspect or
a focal point is an error. A conic or diamond gradient that a plug-in
returns with a focal point loses the focal point.
- Gradient tool: dragging the aspect handle of a radial or diamond
gradient whose file gave it a negative aspect now sets a positive
aspect; only a conic's negative aspect mirrors it.
- Export: PDF, SVG, EPS and legacy .ai write four linear gradients, one
for each quarter of the square, clipped to the shape (PDF as axial
shadings). PDF and SVG write an image for translucent stops, a
dithered fill or a flat square, and for the Perceptual method unless
PDF writes the stops as spot color shadings. SVG writes a diamond on
type characters as a radial gradient through the corners, and so
does CSS. A swatch library saved as CSS gets four corner layers, a
value for the `background` property (a circle when the swatch is
turned by an angle that is not a multiple of 90 degrees). The .ai
editing data holds a radial gradient through the corners. The
document exports give a warning.
- SVG export: a stroke drawn as an image, as conic wedges or as diamond
quarters now covers the miters, caps and arrowheads that reach past
its paint box.
- PDF import reads a function-based shading whose color is the same
along each square about the origin of its space as a diamond.
- Object > Expand gives nested squares or a mesh of rings.
Docs: docs/mcp.md, docs/target-app-parity.md.
A fourth gradient kind, conic (also accepted as `angle` or `conical`),
sweeps the stops once around the center (the gradient's start),
clockwise on the page from the vector, with a seam where the last stop
meets the first. A negative aspect mirrors the sweep, and reflecting an
object turns its sweep the other way, also for a conic without a
vector or with a flat extent.
- Gradient panel: a Conic button in the Type row; the Aspect Ratio
field works for conic gradients and keeps a mirrored sweep mirrored.
- Gradient tool: the extent ellipse, aspect handle and center ring of a
radial gradient, without a focal point.
- Rendering, swatch chips, transforms, warps, plug-in round trips, and
Object > Expand into wedges or a mesh of columns around the center.
- Commands: a negative `aspect` is an error for linear and radial
gradients, and so is a `focal` point for a conic gradient.
- PDF export writes a function-based shading whose calculator function
turns the angle into the ramp, and PDF import reads a function-based
shading that turns around the origin of its space back as a conic
gradient, also when that origin lies outside the painted area. A
PDF/A file, or a conic with more than 97 stops, gets an image
instead.
- SVG export writes 360 solid wedges clipped to the shape for opaque
stops and an image otherwise, and a linear gradient on characters.
- CSS export writes `conic-gradient(from ...)`, with the stops mirrored
for a mirrored sweep.
- EPS and legacy .ai export write 360 solid wedges; the .ai editing data
holds a linear gradient along the vector with the same stops.
- .af files: conical gradients open as conic gradients.
- An export that writes the gradient in another form gives a warning.
Supersedes #2326 and includes switch87's code from it.

The word gap is now the Desired word spacing the layout uses for area type
with Block on (TextObject::layout_justification), with Minimum and Maximum
moved out to it when it lies outside them. The paragraphs keep their own
Justification values, so a wide gap no longer leaves a 1,000 % Maximum
behind, and turning Block off brings back the paragraph's own Desired
value. The SVG writer reads the same values.
- The Contextual Task Bar offers Dynamic Text for area type outside a
thread, beside Convert To Point Type.
- type.dynamicText with wordGap or lineGap and no area type in the
selection is an error instead of being ignored.
- Docs: docs/mcp.md, params text, docs/target-app-parity.md.
* fix(svg): first element of an id, shared linked file reads, bounded blank lines
* address review: cache failed linked-image reads but give each href its own placeholder and link
* address review: charge only blank lines to the line-break budget
* address review: a collapsed line break keeps its measured leading in tiny type
* address review: blank lines use the same scaled leading tolerance
Type › Dynamic Text (`type.dynamicText`, also on the Contextual Task Bar
for type on a path) scales the text by one factor so it fills the span
between its start and end brackets, and the layout fits it again after
each edit to the text, the path or a bracket. The first character's
size moves in 0.1 pt steps within 0.1 to 1,296 pt. Turning it off, or
threading the type, keeps the sizes it was drawn at.
- The model saves `dynamicText` only when on.
- SVG, the legacy .ai writer and the .ai editing data write the drawn
sizes through `vectorcraft_text::drawn`; the editing data warns that
the setting is not written.
- Shrink Text to Fit and Dynamic Text step the size the Character panel
shows when a size measures the cap height, x-height or ICF box.

Part of #4134.
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.
A centred or right-aligned line of tracked type was measured with the
tracking after its last character, so it sat half that tracking
(centred) or the whole tracking (right-aligned) left of where the page
of users' .ai files draws it. That page aligns a line as wide as its
characters without that tracking.
Shaping now records the tracking each glyph's advance holds
(SGlyph::tracking), and a line that isn't justified leaves its last
character's out of the width it is aligned by. The last character is
the last one the line draws before a paragraph's end, a forced line
break or the spaces a wrap leaves; spaces or a tab typed before a
paragraph's end or a forced line break keep the letter's tracking, as
the page does. Forced line breaks and wraps aren't in the files: they
follow the rule so that turning a wrap into a paragraph or a forced line
break keeps the line in place. Hyphenated lines, lines whose last
character hangs, vertical and right-to-left lines and type on a path
keep it. The tracking stays in the glyph's advance, so the caret,
selections, line breaking and Fit Headline are unchanged.
LineInfo::trailing gives the amount. Right-aligned area type sets the
text after its last tab the same way.
What aligns by line widths follows. Convert To Area Type makes its
frame end where the lines are aligned, with room for the tracking, so
tracked type converted either way stays in place. Affinity import lines
up differently aligned paragraphs of artistic text by the aligned
widths. SVG import moves a centred or right-aligned letter-spaced line
back by its share of the last letter spacing, so it stays where a reader
draws it and SVG export, which anchors lines at the end of their
advances, reads back unchanged.
Centred and right-aligned tracked type lays out differently than before
in every document.

A <text> in a <clipPath> was dropped with a warning, so a clip path made
only of text had no content and the art it clipped was hidden. The
clipPath content model in CSS Masking Module Level 1 lists text and use
(https://www.w3.org/TR/css-masking-1/#ClipPathElement).
The importer now clips by the text's glyph outlines, together with any
shapes in the same clip path, and keeps clipPathUnits, the transforms,
clip-rule, visibility, the conditional processing attributes and a clip
path on the text. A <use> in a clip path that shows a text clips the
same way, placed by the <use>; a clip path on the <use> applies in the
<use>'s user space, and a reference goes to the first element with the
id. When the clip path holds only one visible text, with no clip path
of its own and no even-odd clip rule, the clipping path of the clip
group is the text object with no fill or stroke, the same structure
Make Clipping Mask produces for type. A text or a <use> with an id in a
clip path can still be shown by a <use> outside it. Each text's
outlines are laid out once, however many elements use the clip path.
A transform set by a style rule or a style attribute on a text now
places it, as it does a shape. Before, only the transform attribute was
read, inside and outside clip paths.
In horizontal type, tracking and manual kerning are now thousandths of
the em as the Horizontal Scale draws it: at 50%, a tracking of 100 adds
0.05 em after each character. They were added at the full em while the
glyph advances took the scale, so narrow tracked type drifted from the
page of users' .ai files letter by letter. That page writes such type's
character spacing as the tracking itself in a text space as wide as the
scale, which PDF scales by it (ISO 32000-1 9.4.4). Vertical type keeps
the full em: its advances down the column don't all take the scale.
vectorcraft_text::spacing_scale gives the factor. Shaping, inline
graphics and the Optical pairs use it, and so do the conversions from
points back to thousandths of an em: the automatic kerning the Character
panel reads and Touch Type's limits (glyph_em), Combine Point Text, and
PDF import, whose tracking is now the file's Tc. Scale Text Attributes
now keeps tracked type where a horizontal stretch drew it.
SVG export writes letter-spacing in thousandths of the font size it
writes (the vertical scale), so uniformly scaled type keeps its spacing
in a viewer.
Type with both a Horizontal Scale other than 100% and tracking or manual
kerning lays out differently than before, in every document.

Each artboard can carry a guide label: one of the layer colors or a
custom RGB. Guides that belong to an artboard draw in its label color,
and guides without an artboard, or on an artboard without a label, keep
the guide color from the preferences. Selected guides still draw in the
selection color.
- Artboard Options has a Guide Label row (None, the layer colors with
swatches, or Custom with a color swatch).
- artboard.new and artboard.setProps take guideLabel: null, a layer
color's name, or #rrggbb. Any other value is an error. The inspect
summary lists guideLabel when one is set.
- The native format saves the label and skips it when unset; a preset
index outside the layer colors reads as no label.
- artboard.setProps no longer adds an undo step when nothing changes.

The existing entity tests are unit tests that place the references in
attributes. This adds an import-level test with the references inside
<desc>, which the import refuses, and checks that the namespace entities
drawing apps write (&ns_svg;) still import.

A mask, inverted mask or knockout group over type now keeps the region
that covers any artwork. Type is measured by its layout or, on a path,
by the path, and a reader that sets live type in its own font can draw
it wider, so a region sized from that box could cut glyphs off.
A live object (blend, envelope, repeat, mesh, placed document,
intertwine) under a mask is measured as the art the writer writes for
it, expanded on its own with the same limits.
The writer keeps its symbol boxes and symbols' art reach in plain
fields instead of cells.
Opacity masks, inverted and unclipped masks, and knockout groups were
written with mask and filter regions of 200,000 x 200,000 units around
the origin. CairoSVG draws each mask into an image of its region's size
and stops with "out of memory", so a file with any of them did not
open; Firefox drew inverted masks wrong and WebKit drew knockout groups
and inverted masks wrong.
Each region now covers what the masked or knocked-out art paints: its
visual box grown by its raster effects, brush art and members' reach,
the mask art's box, and in a scaled symbol instance its strokes and
effects at their own size. A mask whose art reaches past its object
still comes back whole on import.
A group with a visible member that carries a geometry, Pathfinder or 3D effect, also in an opacity mask, keeps its previous copies. Copies stop at the budget with what each copy's own effects make, and a group's copies count the art of opacity masks.
The PDF and SVG tests for a group's image copies now expect the original on top.
The canvas, the gradient chips and the SVG, PDF, EPS and EMF writers mixed
freeform points in display RGB, while Object > Expand and Create Gradient
Mesh mixed them in the model the points share. Points that are all CMYK,
Gray, Lab or RGB now mix in that model in those places too. Points in
different models mix as before: in display RGB, and on ink planes as the
inks of each point.
This changes how existing art looks:
- CMYK and Lab points. With the default Generic CMYK working space and no
ink planes, halfway between C100 and K100 the canvas drew (17, 106, 139)
and now draws (54, 118, 143).
- RGB points in a working RGB space other than sRGB mix in that space.
- On ink planes (a CMYK document that shows transparency), RGB and Lab
points mix first and then separate.
Gray mixes keep their values, and CMYK and Gray points on ink planes draw
as before. RGB points in an sRGB working space draw as before except on
ink planes.
- PDF and EPS write a gradient whose points are all CMYK, or all Gray in a
CMYK file, as a CMYK image. PDF's Output settings convert it as they
convert any CMYK image.
- Darkening applies to the points before they mix.
- With Appearance of Black set to Rich, the canvas mixes a gradient with a
pure CMYK black point in display RGB, and the point fades from RGB black.
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.

SVG viewers center each <textPath> glyph on its midpoint on the path and
turn it to follow the path, which is how the Rainbow effect draws. Type on
a path with any other effect and no spacing was written as a plain
<textPath>, so a viewer drew it as Rainbow. It is now written as outlines
with a warning, as type with an end bracket, Align to Path or Spacing
already is.
Docs: docs/mcp.md, docs/target-app-parity.md.
Images were keyed by their bytes alone, so two <image> elements that
link different files with the same bytes shared one image key. Every
missing file shows the same placeholder, and files can also be copies
of each other. Export reads a linked file's pixels into the image key
when the document holds only a preview, so once one of the files was
found or changed, the images of the other file exported and printed
that file's pixels.
A linked image's key now also holds a hash of its link's path, as the
.ai reader's linked images do. Images of one file still share a key.
The missing-file placeholder comes from
vectorcraft_doc::links::missing_placeholder instead of a copy in the
SVG importer.
SVG Tiny 1.2 lists class among its core attributes, so the Tiny export no longer drops an object's own classes.

Three tests failed on a loaded machine because they asserted elapsed
time. Each now counts the work that the slow behavior it guards
against would repeat, with a counter compiled only into tests:
- The CSS cascade test counts selector tests, at most two per element
(testing every rule against every element tests N x N). It styles
5,000 elements, so the slow behavior fails on the count rather than
on the hang guard, which now waits 300 s.
- The stacked-glow test counts the silhouettes drawn, 30 for 30 glows
with and without the shadow cache.
- The Zstandard frames test counts the bytes looked at to find the
zero padding.
The hang guards for invalid dash patterns, text layout and script
checks of a pipe wait 300 s instead of 20 s.
SVG text with a textLength came in at its natural width. Following
SVG 1.1 §10.9.1, the characters of each text or tspan with a textLength
are now fitted to it: by spacing them out (lengthAdjust="spacing", the
default), which becomes kerning, or by stretching them
(spacingAndGlyphs), which becomes horizontal scale (kept within
1–10000%). Inner elements are fitted first; vertical text is spaced out
only, with a warning for spacingAndGlyphs. Negative lengths are ignored.
A clipPath with several children was imported as one compound path under
the first child's fill rule, so children wound in opposite directions
cancelled where they overlapped, and an even-odd child after a non-zero
one lost its hole. SVG 1.1 §14.3.5 defines the clip as the union of the
children's silhouettes, each computed on its own.
A clipPath with several children now comes in as a group of them as the
clip group's clipping path, each child keeping its own rule; a group
clips to the union of its members. One child imports as before.
push_num formatted every number with write!("{:.*}"), which runs the
exact decimal float formatter, then scanned and trimmed the text. That
formatter was about 95% of the time to export a path of 200,000
anchors.
At 9 decimals or fewer, push_num now scales the value by 10^decimals
and writes the digits of the rounded integer when that rounding is
certain: the scaled value is below 2^53 and further from a half than
the scaling's rounding error. Ties and larger values still go through
the formatter, so the output is the same byte for byte.
Exporting one path of 200,000 anchors takes a median of 43.4 ms
instead of 167.0 ms, and 20,000 rectangles 81.4 ms instead of 141.4 ms
(Windows 11, release build).
To find the characters that justification or Mojikumi moves, SVG export
without Fewer <tspan> Elements laid out every live type object a second
time, as point type with
Mojikumi None and default Justification options, whenever its paragraph
had Mojikumi on. New type gets Line-end Punctuation Half Width, so every
new type object was laid out twice. Mojikumi only spaces Japanese
punctuation and Japanese letters, so type without them lays out the same
either way.
- TextLayout::mojikumi_applies says whether the text or a list marker
holds a character Mojikumi spaces.
- reader_advances keeps such a paragraph's Mojikumi, and reads the glyphs
from the layout it was given when the object it would lay out is the
same; otherwise it lays the object out again as before.
The SVG is unchanged. Exporting 5,000 point type objects takes a median
of 109.4 ms instead of 171.5 ms on Windows 11.
