dotCooCoo 40f4c920e7 Type: Bunri-Kinshi keeps inseparable character pairs on one line
Paragraph panel menu > Bunri-Kinshi (with the East Asian options) and
text.setFormat {bunriKinshi} turn it on per paragraph. A line then
never breaks inside two em dashes, two horizontal ellipses, two two-dot
leaders or the two halves of a vertical kana repeat mark, the pairs W3C
JLREQ lists for class cl-08 (https://www.w3.org/TR/jlreq/#cl-08), nor
inside a chain of em dashes. Both composers, vertical type, Kinsoku
Shori Type, hyphenation and No Break follow it, and a pair wider than
the line stays whole on it. Justification and letter spacing add no
space inside a pair.

The setting works only with a Kinsoku Set: with Kinsoku Set None the
paragraph keeps the value without effect and the menu item is
unavailable. It is off by default, saved with the paragraph only when
on, carried by paragraph styles (Paragraph Style Options > East Asian
Composition Settings), and turned off by Reset Panel. A value that is
not true or false is refused. The .ai editing data has no field for it,
so saving reports a paragraph with it on and a pair in it as left out.

dotCooCoo 812cf5f4cd .ai save: RGB values are written in the working RGB space
Plain RGB fills and strokes and RGB gradient stops were written with
their display RGB values. The reader reads those values as working RGB,
so with a working RGB space other than sRGB a reopened file was saved
with different RGB values and CMYK equivalents. They are now written
with the color's own RGB values, as global process and spot colors
already were.

A spot color in a gradient stop now writes its RGB values from its full
color as the palette writes it (Lab to four decimals and clamped), the
same values its CMYK equivalent comes from.

dotCooCoo 6213d1c471 EPS tests: the reader's long tests check counts and shared state instead of a 20 s limit
many_tiling_patterns_and_spot_inks_read_in_linear_time checked that a
program setting 200,000 different tiling patterns and 200,001 spot inks
reads within 20 s of wall-clock time. It reads in about 4 s alone; while
the crate's full test suite ran in parallel it took more than 20 s and
failed.

In test builds, the tiling pattern lookup now counts on its thread how
many patterns it compared with the one it looked for (tilings_compared,
gated with cfg(test) like SELECTOR_TESTS in the SVG reader's CSS). The
test, renamed many_tiling_patterns_are_found_again_through_a_hash, reads
through import on a thread of its own and asserts that its 200,000
lookups compared at most 200,000 patterns in all. When every pattern
hashes alike, as when each lookup went through every pattern made so
far, the lookups compare 19,999,900,000 and the test fails. The test
still reads the 200,001 spot inks and checks their swatches, but it does
not count or time their lookups.

The other tests that read through read_soon wait 300 s instead of 20 s,
as a guard against a read that never ends; their budgets and limits
decide what they check. work_on_the_longest_dash_pattern_ends_soon (4.5 s
alone) now also checks that the states gsave, grestore, gstate,
currentgstate and setgstate save, make or set hold the one 65,535-entry
dash pattern, so a copy of the pattern in any of them fails it.

dotCooCoo 3e46408ab5 EPS import: cshow and kshow procedures see the font PLRM gives them
In a CID-keyed font whose CIDFont the file only names, a cshow procedure
now runs with the CIDFont as the current font, rootfont gives the
composite font, and the procedure gets each code's last byte. A show in
the CIDFont shows the character of that code, and any other string is a
rangecheck error. The current font is restored after each procedure.

A kshow procedure no longer leaves a font it sets current: the current
font is restored when the procedure completes, for every font, and a
kshow the procedure runs sees the font the procedure set.

In GBT-H and CNS2-H, whose mappings are not read, a byte that starts no
row-and-cell code is a code of its own.

docs/gaps.md dates this G9 work in a bullet of its own.

dotCooCoo 91e1412d77 Effects: Roughen at size 0 keeps the outline
With Size 0, Roughen moved no point but still replaced each segment
with its Detail's points joined by straight lines (Corner) or by a
smoothed curve through them (Smooth), so a curved path lost its shape.

At Size 0 each segment is now split at the Detail spacing into pieces
of equal length on the segment itself, with `pathtools::insert_at`: a
straight segment gets corner points without handles, and a curve gets
smooth points whose handles follow it. The path keeps its outline with
Smooth or Corner points alike. The params text of `distort.roughen`
describes size 0.

`insert_at` now counts the anchors added before each returned mark in
one pass. It counted them again for every split segment, which took
quadratic time on a path with many split segments. Its results are
unchanged.

Existing documents with a Roughen of Size 0 on a curved path, or with
Smooth points, draw differently.

This is VectorCraft's own rule. What Roughen does is described in

dotCooCoo 66f6be77ee .ai save: RGB and named colors keep their CMYK equivalents when a reopened file is saved
The .ai writers write RGB and Lab values to four decimals next to a CMYK
equivalent, but converted that equivalent from the color at full precision.
When a file was read back and saved again, its CMYK equivalents differed in
the fourth decimal (for example 0.6831 and 0.6832). In the editing data this
affected plain RGB colors, RGB gradient stops, global process and spot colors
and the header's custom colors; in the legacy .ai writer it affected RGB
gradient stops.

The CMYK equivalent of an RGB color, and of a global process or spot color,
is now converted from the values as they are written, so both saves convert
the same values. Lab values of global process and spot colors are now written
clamped to the range the reader reads (L 0 to 100, a and b -128 to 127).

A plain Lab fill or stroke and a Lab gradient stop are still written as RGB
with a CMYK equivalent converted from the Lab values. The reopened file holds
them as RGB, so their CMYK equivalents change once on its next save.

The art style round-trip test now compares the program exactly; its blanked
CMYK values and the four-decimal tolerance are no longer needed.

dotCooCoo 6208a8cc3e EPS import: charpath, cshow, kshow and glyphshow read named CIDFont type by its CMap
- `charpath` in a CIDFont only named, over a predefined CMap, adds the
  outlines of the characters its codes stand for, placed as `show` sets
  them, and moves the point as `show` does. It added no outlines.
- `cshow` gives its procedure each code of such type, two bytes for a
  two-byte code, with the code's width. It split two-byte codes into
  single bytes.
- `glyphshow` sets the named character itself. It set the character's
  UTF-8 bytes as Latin-1 letters.
- `kshow` runs its procedure between each two codes of such type, with
  the two codes' values. It didn't run it. The procedure sees the font
  the file set as current, and a font it sets stays current.
- A name that ends in the row-and-cell CMap `H` or `V` splits off the
  CMap only when the file defines the CIDFont of that name (as a
  resource or with `definefont`), or the name has a hyphen and an
  installed face that covers Japanese has it. `Foo-Bold-H` stays a font
  of the whole name.
- In a CMap that can't be read (`GBT-H`), each code moves the point one
  em, along the line or down the column; a tab or carriage return byte
  is a code of its own.
- One parser reads the names of the predefined Unicode CMaps, for EPS
  and legacy `.ai` type.
- Outlines added to a path by `charpath` stop at the path's point limit.
- docs/file-format-parity.md, docs/gaps.md and docs/mcp.md describe type
  in named CIDFonts over the predefined CMaps.

dotCooCoo 91d705e155 Gradients: repeat or reflect a gradient's stops a set number of times
A linear, radial, conic or diamond gradient has a spread: Pad (the
default, as before), Repeat or Reflect, with a count of 1 to 100
(VectorCraft's own limit). Repeat and Reflect run the stops that many
times along the vector (around the turn for a conic) and keep going past
both ends, Reflect running every other run backwards, as SVG's
spreadMethod does.

The Gradient panel has a Spread menu and a Repeats field, and the
Gradient tool marks where the runs meet. paint.setFill and
paint.editGradient take `spread` and `repeats`; bad values are errors.
Presets, swatches, blends, strokes along or across a path, Outline
Stroke and Object › Expand follow the spread; Expand gives each run the
same whole number of objects, and Outline Stroke's mesh keeps the color
on each side of a sharp step between two stops at one offset.

SVG writes and reads spreadMethod: SVG import now reads a repeating or
reflecting gradient as one that repeats or reflects once, instead of
expanding its stops over the shape. CSS writes repeating gradients.
PDF writes a conic's sweep shading over one run. PDF, EPS, legacy .ai
and the .ai editing data write the other kinds with their stops
repeated across the shape: at most 256 runs and 16,384 stops (256 stops
in .ai files), and for a radial or diamond no farther than 65,536 runs
from its center, with a warning past those. PDF import now finds sharp
steps in any axial or radial shading instead of blurring them.

dotCooCoo f6a1ec1019 .ai save: the editing copy keeps brushes and brushed paths
The editing copy of a PDF-compatible .ai now holds the Brushes panel's
Calligraphic, Scatter and Art brushes in the panel's order, with the art
of Scatter and Art brushes. A path or compound path with a Calligraphic
brush, or with an Art brush in Tints whose art bends along the path,
keeps the brush on its stroke. Other brushed strokes are still written
as their brush's art.

The writer reads each brush back with the reader's code before writing
it. Brushes that would not come back with their settings, brushes past
the reader's limits and every brush on a large canvas are left out with
a warning. A brush that has the name of an earlier brush that was left
out is written, and no path is written with it on its stroke.

An object linked to a graphic style that is left out at the object
limit now also raises the warning about links left out.

dotCooCoo 842f1f1b68 EPS import: CIDFonts only named, over a predefined CJK CMap, set their characters as live type
Type in a font found by name with a predefined non-Unicode CMap, such as
`/Ryumin-Light-83pv-RKSJ-H findfont` or a `composefont` with `GBK-EUC-H`,
opened as Latin-1 letters (`ú{A` for 日本A) in a font whose style carried
the CMap name (`Light-83pv-RKSJ-H`). Only Unicode CMaps were split off the
font name, and `composefont` failed with `undefinedresource` for the others.

- The predefined CMap decoder used by legacy `.ai` type moves to
  `import/predefined_cmap.rs`, and EPS import decodes these CMaps' codes
  with it (Shift-JIS, EUC, GBK, Big Five, UHC and the other public CMaps).
- A font name splits at a predefined CMap unless an installed face has
  the whole name. A CMap that can't be read gives a warning.
- Type over a vertical CMap (`-V`) is set as vertical type, and each code
  moves the point one em down the column, the default `DW2`
  displacement.
- Every show operator sets decoded type with the same spacing and shaping
  as other fonts found by name.
- Decoding a string counts against the import's memory budget.

jmvergesandClaude Opus 5.5 ba34df9543 .ai import: type filled or stroked with a pattern keeps its pattern (#6856)
In the text document of a .ai's editing copy, a character's fill (key
53) or stroke (key 54) is a paint with a colour under key 0 and, under
key 5, the name of an art style of the editing data. For a pattern
swatch, key 0 is black and the pattern is only in that style: a style
of one paint (/SimpleStyle) that paints with `(name) ... [matrix] p`.
The reader took key 0 alone, so type painted with a pattern came in
black.

The art style reader now keeps the pattern of a style that is one
paint, and the import places it as a path's pattern fill would be (its
matrix in art space; the files' own pages tile such type with it), by
the style's name. A run whose fill or stroke is on and names such a
style takes the pattern, in the type's text space, so its tiles stay
where the document has them. A pattern the file doesn't define or can't
place, a key 5 that isn't a string, and a style of any other paint keep
the colour as before.

A style that also has filters gives no pattern for type, and a pattern that
can't be placed in the type's text space keeps the colour. A .ai saved
again writes such type as outlines with a warning, as it already does for
any type with pattern paint (#5965).

and TY for a Kumi block in horizontal text recorded for later vertical
use. The writer now writes 1 Tv and 0 Tv, and 1 TY and 0 TY, where a
run's mark changes, closes an open Kumi block before the text object
ends, and writes neither operator for type without the marks. The
legacy .ai reader reads both back onto the same characters. The prolog
defines Tv and TY so the file still runs as PostScript.

dotCooCoo 66d21471ae Gradients: diamond gradients run the stops from the center out to a square
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.

dotCooCoo e609b26a95 Warp: bend each style as one Bézier patch, and keep saved warps' look
Each of the fifteen Warp styles now bends the bounds as one Bézier patch.
The style sets the patch's control points from the bend and the size of
the bounds, the horizontal distortion scales each column of control
points about its middle, and the vertical distortion scales each row.
The Warp effects and warp envelopes share the map (`WarpNet`). Content
with no width or no height takes the middle of the patch along that
side.

A warp carries the map it draws with as `version`. New warps, the
built-in graphic styles' Warps and warps opened from .ai files get 1.
Warps in .vectorcraft documents saved before the version existed read
as 0 and keep the earlier map, so those documents keep their look.
Edits keep a warp's version, and Warp Options editing several objects
keeps each one's own. effect.apply, effect.setParams and the warp
envelope commands take `version` 0 or 1 (`1.0` counts as 1) and refuse
any other value. An .ai file holds a warp's settings and not its
version, so a version 0 warp saved to .ai opens again with version 1.
The .ai writer compares a style's settings without the version, so
saved warps still export as editable effects.

public document describes these records. This is VectorCraft's reading
of them, and under it the meshes match the flattened page that the same

The reader gave the first tint to the first ink listed, so mesh areas
came in with the wrong inks, yellow as cyan. Where enough of the art
changed, the layers no longer matched the file's page, and the file
opened as its page instead of its objects.

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.

dotCooCoo 39683ecdd9 PDF/.ai export: fit Dynamic Text before resolving font heights
The legacy .ai writer resolved cap-height and other font height
references to em sizes before fitting, so Dynamic Text stepped and
limited the em size instead of the size the Character panel shows, and
the type could be written smaller than it is drawn. It now fits first,
and outlines come from the type's own layout.

The editing data now also warns that Dynamic Text is not written when
the type is written as outlines.

dotCooCoo b426822a9c Type: Release Type on a Path keeps the size Dynamic Text drew the type at
Release Type on a Path copied the stored runs into point type with the
Dynamic Text flag still set, so the text dropped back to its stored size
and the file saved the flag on point type. The point type now gets the
drawn sizes and the flag is turned off.

The legacy .ai writer writes Dynamic Text type at its drawn sizes; it
now also warns that the setting itself is not written, as the editing
data writer does, whether the type is written as text or as outlines.

docs/target-app-parity.md lists reshaping or scaling the path among
VectorCraft's own rules, and a task bar comment marks leaving the item
out for threaded type as VectorCraft's own rule.

jmvergesandClaude Opus 5.5 543034987e Envelopes: type's strokes paint at their own weight along the bent outlines (#6644)
With Envelope Options > Distort Appearance on, VectorCraft turned the strokes
of type in an envelope into filled outlines and bent them with the art, so a
stroke got thinner where the grid squeezes the type and thicker where it
stretches it. The drawn art of users' .ai files keeps those strokes as stroked
paths at the type's own weights, and the ring they paint is as wide wherever
the grid squeezes or stretches the type. An envelope of stroked type in such a
grid therefore didn't draw as its drawn art and kept it instead of opening live.

Type's strokes (its characters' and those on its own appearance) now paint
along the bent glyph outlines at their own weight, with Distort Appearance on
or off, also in an envelope inside an envelope:

- doc: `map_node` maps the groups that hold type's glyph outlines with
  `Hooks::type_appearance` in place of `Hooks::appearance`, for type in the
  envelope's contents and for type that a live object in them (an inner
  envelope) outlined (`Warper::type_outlines`). Such a group's opacity mask
  is mapped with the ordinary hooks, so it bends as other art does. Groups
  marked as type's outlines in the contents themselves (art an earlier Expand
  made) stay plain art.
- effects: `bake_type_appearance`, `bake_appearance` with strokes kept as
  strokes: geometry effects on type's fills and strokes still bake in and bend.
- doc: `max_outset` counts type's character strokes as type's own visual
  bounds do (`char_stroke_outset`). It left them out, though they already
  painted past an envelope's grid where the glyphs reach its edge; this also
  grows the visual bounds of blends and repeats of stroked type and the reach
  of symbol art holding it.

Paths' strokes, geometry effects, opacity masks, linear gradients and pattern
fills bend as before. The canvas, hit testing, effect bounds, Expand, every
export and the .ai save take the evaluation from the same hooks. Expand of an
envelope of stroked type gives the bent outlines with the strokes on them.
This changes how VectorCraft's own envelopes of stroked type draw.

dotCooCoo 2606b70604 Type: Dynamic Text sizes type on a path to fill its brackets
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.
