The legacy reader skipped `TV`, `Tv`, `Ty` and `TY` of section 15.3.4 of
the version 7 file format specification, so type set with `1 TV` opened
horizontal.
- `TV` sets a text object's writing direction. VectorCraft keeps one
direction for each text object, the one in force at its first
character, with a warning when a later character has another.
- `Ty` marks a Kumi block as a Tate-chu-yoko run, which is VectorCraft's
own mapping, and `TY` does the same in horizontal type. A `TY` block in
vertical type opens unmarked. Two blocks with nothing between them open
as one block.
- `Tv` sets Standard Vertical Roman Alignment.
All four are modal, and an operand other than 0 or 1 leaves the value as
it was.
Docs: docs/file-format-parity.md.
The reader gives an Xy right after a compound path or a text object to
that object. The writer now writes XR before the Xy of type, images and
guides, so type next to type, a compound path before type, image or
guide, and type before an image or guide keep their own opacity, blend
mode and knockout shape flag.
- Type keeps its Isolate Blending and Knockout Group state in a state
block after its text object, as its outlines did on their group.
- The reader no longer gives a layer the Xy before its last text object.
- The ASCII85 end marker of the text document stays on one line.
- The warning and docs/file-format-parity.md also list area type in an
open frame, type on an open path whose ends meet, type of only white
space and threads of type on a path as written as outlines.
- README.md, ROADMAP.md, docs/gaps.md, docs/roadmap.md and
docs/target-app-parity.md describe the editing copy a saved .ai holds.
- clip_path's doc comment is back on clip_path.
- import_fuzz reaches threaded area type and vertical type.
The editing copy of a PDF-compatible .ai wrote every text object as its
outlines. Point type, area type and type on a path are now written as
text: a text object in the layers that names its story, and the text
document after the document data (%AI11_BeginTextDocument) holding the
stories.
- Each story holds its characters (a paragraph ends in \r, a forced line
break is \x03), its character runs (font, size, leading, tracking,
baseline shift, horizontal and vertical scale, solid fill and stroke
with its weight, capitals, Tate-chu-yoko) and its paragraph runs
(alignment, indents, space before and after, hyphenation, right-to-left
direction).
- Point type keeps its point and, when it is turned, its matrix. Type
scaled by one factor, such as all type on a large canvas, has its scale
in its sizes, frame and path. Area type keeps its frame, rows,
columns, gutters and first baseline, type on a path its path and where
it starts and ends, and vertical type its orientation. A threaded story
is one story through its frames in order. Area type and type on a path
carry their frame's path in the layers as well.
- Type the text document can't hold is written as its outlines, with a
warning: type in opacity masks, pattern tiles and art cut to a clipping
object, mirrored type, turned or unevenly scaled area type and type on
a path, frames of several parts, area type that flows around a text wrap,
threads whose frames differ in orientation or include a frame written
as outlines, type and stories past the sizes the reader reads, and type
with inline graphics, ruby, gradient or pattern paint or an appearance
or opacity mask of its own. Other character and paragraph attributes are left out, with
a warning.
Tracking is written as a whole number of thousandths of an em, and
solid paints as simple paints; tracking that isn't a whole number is
rounded, with the warning.
Each construct is written in the form VectorCraft's .ai reader reads
(crates/eps/src/import/ate.rs at 36ef34dfdd: Texts::read :407, story
:501, frame :456, para :562, style :588, paint :622, AreaFrame::read
:284; the text object in import/ai/read/art.rs:15 and its path in
import/ai/frames.rs:26), and the tests read the written data back
through that reader. The scripting
reference documents the same attributes on the reading side (text frame
kinds, columnCount, columnGutter, rowCount, startTValue, endTValue,
orientation, and the character attributes):
https://web.archive.org/web/20160410101607/https://wwwimages.adobe.com/content/dam/Adobe/en/devnet/illustrator/sdk/CC2014/Illustrator%20Scripting%20Reference%20-%20JavaScript.pdf
The reader now closes a text object's frame path painted with a closing
operator (n, f, s, b, h), so area type's frame comes back closed; places
point type whose story keeps no composed lines at its frame's point;
keeps a story's last empty paragraph (only the \r that ends the story is
dropped); gives type made from the text document its text object's lock,
as it gives it its visibility; and gives type its text object's knockout
shape flag, as it gives it its opacity and blend mode.
Tests: the round trip of every kind of type and its state, a second
write of what is read back giving the same bytes, the text document and
stubs, scaled point type, a story split between threaded frames, the
fallbacks and the warnings, and the engine's editing copy with every save
option; a fuzz case for damaged text documents and stubs.
Docs: docs/file-format-parity.md.
A path with an Art brush comes in as the path, with the brush on its
stroke at its weight, instead of as its drawn look, when the brush
stretches art of solid-filled paths along the path, unflipped, at 100% in
Tints. The art runs on the side of the path the file draws it.
The drawn look stays for other colorizations and widths; Proportional,
between-guides and flipped brushes; type; a path with settings of its own,
a variable width, effects, a swatch stroke or an entry that isn't read;
and art with strokes, gradients, patterns, masks or effects, or no length.
A brushed stroke, Calligraphic ones too, takes the brush the Brushes panel
keeps under its name, and an image with a brush keeps its drawn look.
In every document, Tints and Tints and Shades take art in black ink alone
by its ink amount, and a process or gray stroke color's tints and shades
stay in that color's model.
Place and Expand bring the brushes the art uses, renaming on conflict.
Part of #637.
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.
A section scan lexed a /ForeignObject's /Data, a /Binary dictionary's data and a text document's data as tokens. A `%_` line of that data holding a `(` opened a string, so the section ran past its end marker: the editing data failed to read, or the art after it was misread. Reader::section now skips the data up to its `~>`, as the reader does for art outside a section. Data without its `~>` before the section's end marker is not skipped. The scan for swatch names does the same.
A new test binary opens a document of 13 type objects with the plans a
font face keeps and again while every shaped segment makes its own plan.
The document, its cached bounds and baselines included, and the first
frame's pixels must be the same. `test_fonts::keep_shape_plans` switches
the plans off; it exists only in tests and with the `test-fonts` feature.
The engine's open test now builds objects of one script and direction
that differ in kerning and language, and lays each one out in a font
database of its own, so a plan used for the wrong features fails its
comparison. It no longer sets Arabic, which could fall back to a system
font in one database and not the other.
A group whose style holds Effect › Pathfinder › Intersect, Exclude, Subtract,
Minus Back, Divide, Outline, Trim, Merge, Crop, Hard Mix or Soft Mix now opens
with its members editable and the effect live, as Add already did
(https://helpx.adobe.com/illustrator/desktop/manage-objects/reshape-transform-objects/combine-objects-using-pathfinder-effects.html).
The Command numbers 1 to 10 are VectorCraft's own reader rules, learned from
saved files. Soft Mix's number 11, and reading its Mix from 0.01 to 1 as a
Mixing Rate of Mix times 100, are also VectorCraft's own reader rules.
These still open as the drawn look:
- Trap, and the effect on a path, on type, on a layer or on a fill or stroke.
- Any operation whose saved Pathfinder Options (Precision, Remove Redundant
Points, Divide and Outline Will Remove Unpainted Artwork), ConvertCustom,
Mix or Trap settings differ from the values the reader accepts, although
only Soft Mix uses Mix and none of these operations uses the Trap settings.
The import fuzz test now also gives the style every option with any Mix, and
checks that a live Soft Mix's rate is from 1 to 100.
The reader measured a symbol's definition only to find the page art an
instance covered, so every file with a placed symbol instance opened
with that instance as drawn art, or as its page.
- Each `%AI14_BeginSymbol` definition is read by a reader of its own into
a symbol of the document, with its art (in the symbol's space, y down),
the registration point its dictionary gives
(`AI13PatternRegistrationType`, 1 to 9 from the top left) and the
instances of other symbols in its art. A definition whose art isn't
read whole isn't kept: type, placed files, non-native art, pattern
fills, a gradient or an image the reader can't read or place, and
anything else the reader doesn't read. Its instances come in as the
page draws them, within the box of the art that is read. A definition
that holds an instance of a symbol the file doesn't have isn't kept
either, nor is a definition holding an instance of one of those, and
their instances aren't read. A definition after the first layer isn't
read.
- `%AI24_BeginSymbolList` orders the symbols as the Symbols panel lists
them. A name read twice is numbered ("Dot 2"), and instances name the
first symbol with the file's name.
- `/SymbolInstance` with `/SymbolRef` and `/RTransformMatrix` comes in as
a live instance, with the hide and lock set before it and the opacity,
blending mode, isolation and knockout of the `Xy` after it, as a
group's. An instance with appearance changes of its own
(`AI19SymbolAppearanceMap`), of a symbol that isn't read, or placed
only by `/Matrix` or `/Transform`, comes in as the page draws it.
- Symbol art takes the gradients and art styles read before it, and an
object in it linked to a listed graphic style keeps the link.
- In a symbol's art, the matrices of instances, gradients and images are
read in the canvas's space, y up, about the canvas point of the ruler
origin. Without `%AI3_TemplateBox` an image can't be placed, so the
symbol isn't kept.
- At most 4,096 definitions are read, and a symbol list names at most
16,384 symbols.
Tests: reader tests for each case above, and fuzz cases for damaged and
hostile symbol data.
An art style with a Distort & Transform effect opened every object but
type as its drawn look. Objects other than type now open as themselves
with these effects live:
- Any object takes a Tweak that moves nothing and Pucker & Bloat at 0,
beside the effects it already took.
- A path, compound path or group takes Transform without copies, or a
Free Distort whose corners make a parallelogram, when it is the only
effect. Neither the style nor anything in the object may paint with a
gradient or pattern. Everything in the object must be a path, compound
path or group without a clip, an opacity mask or effects of its own.
When Transform scales, rotates or reflects, nothing in the object may
be stroked.
- An unstroked path or compound path whose segments are all straight
takes Twist when it is the only effect.
Other objects keep the drawn look, as do Zig Zag, Pucker & Bloat of
another amount, a Free Distort with other corners and Transform copies.
Docs: docs/file-format-parity.md, docs/target-app-parity.md.
A .ai or EPS graphic style library holds graphic styles and their list
in its editing data but no layers, so it came in as its PDF part or
page with the default styles, and Other Library listed those. A file
read as its PDF part or page, because it has no layers or its layers
can't be used, now gets the styles of its list, in list order, as a
file read from its layers does: File > Open shows them in the Graphic
Styles panel and Other Library lists them in a library panel.
Style stroke weights and effects are scaled by the Large Canvas factor
of an EPS, and for a .ai whose editing data is in the units of its
pages by the pages' UserUnit or the declared Large Canvas scale.
Part of #3349
A tab definition in type of the legacy format (`numDots numTabs Xb`, a
`leader decimal tabType tabPosition Xe` for each stop, then `XB`) was
skipped, so every paragraph opened with only the default stops every
36 pt. The stops it describes now become the paragraph's tab stops
(left, center, right or decimal, at their positions), and they last
into the next paragraphs and text objects like the other paragraph
attributes. A definition with no stops, or whose descriptions were all
skipped, leaves the default ones. A description with an unknown type or
a position outside 0 to 100000 pt is skipped, and so is one past the
first 1024 of a definition. A text object's `To` ends a definition that
an earlier object left open.
Docs: docs/file-format-parity.md.
In the legacy format, `Tr` sets the rendering mode of the type that
follows. Section 5.7 of the version 7 specification says that modes 4 to
7 make the text object a mask: 4, 5 and 6 also fill, stroke, or fill and
stroke it, and 7 paints nothing. Sections 15.3.2 and 15.4.5.1 add that
these modes are used in pattern definitions, and the reader does not
read type in a pattern. The reader painted 4 to 6 like 0 to 2 and never
clipped, so the art a text mask clips showed whole.
A text object with characters in modes 4 to 7 is now a clipping path of
its clipping group (`q` ... `Q`, or the layer), as a path painted with
`W` is, and the whole object is the mask. Beside other clipping paths it
nests as they do, and the mode lasts into later text objects. Area type
with linked areas (threaded frames, also when the reader's limits keep
one frame), and type in wraparound text or in a compound path, a group
inside them included, doesn't clip, with a warning.
A `Tr` operand that is not a whole number from 0 to 9 now leaves the
mode as it was; before, 4.5 read as 4 and -4 hid the type.
The new warning and the reader's warning about linked type areas left
out get rows in every catalog.
The Adobe Illustrator File Format Specification 7.0, section 4 (p. 51),
says the name shown for a global object is the part of its name in the
file before the newline
(https://13thmonkey.org/documentation/fonts/AI7FileFormat.pdf). The
legacy reader kept the whole name, so swatches and patterns came in
named "Sky\n1". The reader now applies this rule to the files of every
version it reads.
- Gradient swatches, gradient fills, pattern definitions, pattern fills,
palette cells and art-style pattern fills use the part before the
newline. Lookups inside the reader still use the whole name.
- When that name is taken, the first free "Sky 2", "Sky 3" is used.
Taken names are None and Registration, the palette's own swatch and
group names, the default swatches when no palette replaces them,
named colors (color operators, gradient stops, version 7 pattern
strings, the header's and an EPS program's custom colors), the names
of gradients and patterns that have no newline, and the names given
to earlier gradients and patterns. Only content the reader reads
counts: not the alternates of versioned content, the prolog, skipped
sections or what follows the trailer.
- A name with nothing before the newline comes in as "Gradient" or
"Pattern". Names without a newline do not change.
- docs/file-format-parity.md lists the rule.
In the legacy format, `TZ` makes a re-encoded font from an existing one
and can give it encoding pairs of its own, which change only that font's
encoding. Its `useDefault` operand says whether the file's `TE` encoding
also applies to the font (Adobe Illustrator File Format Specification
7.0, section 3.3.1,
https://13thmonkey.org/documentation/fonts/AI7FileFormat.pdf). The
reader skipped the body of `%AI3_BeginEncoding` sections and ignored
`TZ`, so every string was decoded with `TE`'s encoding.
Strings in a re-encoded font are now decoded with its own pairs, then
with `TE`'s encoding when `useDefault` is 1, and as Windows-1252 for the
codes left. Strings in other fonts keep `TE`'s encoding. The reader
reads `TZ` in the body of an `%AI3_BeginEncoding` section and wherever
else it appears in the script, with or without the direction operand
and the Multiple Master weight vector. The font names are the last two
names, and only numbers and the weight vector may follow them; the
reader does not use a `TZ` of another shape. The first `TZ` for a font
is used.
`TZ`'s font names also map the re-encoded font to the font it was made
from, as the `%AI3_BeginEncoding` comment does. Type in a re-encoded
font that no such comment names now opens in the font `TZ` names; when
both name the font, the first one read is used.
The version 7 and version 3 file format specifications list three text
operators the editing-data reader did not dispatch, so a file whose type
used any of them on a visible layer did not open from its editing data:
- `(text) justified TS` (special characters): the reader adds its
characters to the story, as it does for `Tx` and `Tj`.
- `Te` (end render) is read and ignored. The reader accepts it with any
number of operands.
- `TM` (pop text matrix) is read and ignored.
Tests cover each operator in a text object, `TS` without a string and
outside a text object, and `Te` inside a tab definition. The import fuzz
tests add the operators to the legacy type tokens.
The version 7 file format specification gives `XI` and `XF` an
ImageMask operand: 0 is an opaque image, 1 is an image that is
transparent and can be colorized (sections 8.1, 8.2 and the 1-bit
examples in 8.4,
https://13thmonkey.org/documentation/fonts/AI7FileFormat.pdf). The
reader ignored the operand, so a 1-bit image mask opened as an opaque
black-and-white image.
A 1-bit gray image with ImageMask 1 now opens with the fill color set
before it as the color that colorizes it. A spot or global color keeps
its swatch and tint. When the fill is a pattern, a gradient or none,
the image is colorized black. VectorCraft's own rule is that the pixels
that open black with ImageMask 0 take the color and the others are
transparent. A linked image (`XF`) keeps the same color for when its
file is relinked. 8-bit gray, RGB and CMYK images, and images with
ImageMask 0, open as before.
In `.ai` and EPS editing-data import, a clipping group, layer or opacity
mask's art that holds more than one clipping path (`W`) now clips to the
intersection of the paths, as each `W` intersects the current clip (AI7
spec section 5.6.2,
https://13thmonkey.org/documentation/fonts/AI7FileFormat.pdf). Before,
the paths were joined into one compound path, which clipped to their
union, and kept a stroke only when every path had the same one.
Each clipping path after the first clips a clipping group nested inside
the one before it, and keeps its own stroke, opacity and blend mode. The
innermost clipping group holds the art in the order written; as before,
every object in the group is clipped by all of its clipping paths. A
clipping path's painted fill stays at its path's level. A compound path
of clipping paths (`*u` ... `*U`) is still one clipping path. Clipping
paths that would nest the art past the document's 32 levels stop the
editing data from being read.
The editing copy of a PDF-compatible .ai wrote every image as its outline
filled with its average color. Embedded images are now written with their
pixels, and linked images as placed files with a preview:
- Embedded images are rasters in the form of the version 7 specification
(section 8, https://13thmonkey.org/documentation/fonts/AI7FileFormat.pdf):
%AI5_BeginRaster, the color space, the image matrix and the XI operands
of current files, then the samples in binary in a %%BeginData section.
Gray, RGB and CMYK images keep their samples (CMYK images their ink
amounts), and see-through images their alpha channel after the color
samples. The matrix is written to ten decimals.
- Linked images are placed files (section 16): the matrix, the box of the
file's pixels and its path, %%IncludeFile, the folder relative to the
document's (when the relative path ends in the path's file name), and a
preview of at most 256 pixels a side.
- Images that can't be decoded or have more than 33,554,432 pixels (the
most the reader reads) are written as their outlines filled mid gray,
images of 16 bits a channel (CMYK TIFFs included) at 8 bits, and linked
images in opacity masks and pattern tiles as embedded images, each with
a warning.
Each of these is written in the form VectorCraft's .ai reader reads, and
the tests read the written data back through that reader.
The reader now gives an image its name and opacity mask when the
operators that end its raster (XH, Xr and the N after %AI5_EndRaster) come
before its dictionary, reads an empty relative folder as the document's
own folder, and looks for the %%EndData that ends an image's samples
after the alpha channel its XI operands give it, preferring one whose next
line is XH, so samples that hold the marker's bytes are read whole.
Tests: the round trip of every kind of image and its state, a second write
of what is read back giving the same bytes, the raster and placed-file
forms, previews of large linked images, and the engine's editing copy with
every save option; a fuzz case for damaged images and placed files.
Docs: docs/file-format-parity.md.
In the legacy format, area type whose story flows through several linked
areas has one text path (`Tp` ... `TP`) for each area, each with its own
matrix and frame (version 7 specification, sections 15 and 15.5.3). The
reader kept only the first frame, placed it with the text object's last
valid matrix, and put the whole story in that one frame.
Each linked area with a frame now opens as its own area type object,
placed with its own matrix, and the frames are threaded in file order.
The first frame holds the story: the characters after every `TP`, and
the overflow text. When the file opens, the story is laid out again
through the thread (section 15.1 lists the flow from area to area as
final-form information). A linked area without a frame is left out.
Area type with one area opens as before.
The dictionary that follows a text object (its opacity mask, text wrap,
name and other keys) went to its one object. Its opacity mask and text
wrap now go on every frame, and its other keys on the first frame.
Point type is read with its first text path's matrix, and type on a
path with the matrix and start of the first text path that has a path.
Area type with no frame at all opens as point type with its first text
path's matrix. Before, these used the last valid matrix and, for type
on a path, the last start.
One text object reads at most 4,096 text paths. The number of frames
times the story's character count is kept to 4,194,304, so a longer
story keeps fewer frames. Frames past either limit are left out, with a
warning.
A legacy .ai in the version 7 form names a linked image's file with
`(path) modified XG` and draws the image with `XF`, which takes the
operands `XI` takes and has no samples after it (Adobe Illustrator File
Format Specification 7.0, sections 8.2 and 8.3). The reader ignored both
operators, so the image was dropped without a warning.
- `XF` after `XG` becomes a linked image of that file, its pixels placed
as an `XI` image of the same operands is placed. The file keeps no
pixels of it, so a placeholder stands in until the file is relinked in
the Links panel, with a note in the open result. No pixels are read,
so the image is not held to the pixel limit of `XI`'s samples.
- An `XF` without a file name before it, or with operands `XI` couldn't
read (no matrix, too few numbers, no pixels, or samples of other than
1 or 8 bits), is left out with the existing "an image VectorCraft
can't read was left out" warning. An `XG` applies only to the image
after it in the same raster object; `() 1 XG` before an embedded `XI`
keeps that image embedded.
- A PostScript page draws nothing for `XF`, so there the placeholder's
area is left out of the comparison of the layers with the page, and
the file keeps its layers. A PDF part draws the image's pixels, so a
file with one is compared with it there as before, and its layers are
not used without the PDF part.
- Linked images of different files get image keys of their own even
when they show the same pixels (the placeholder, or two identical
placed-file previews), so updating or exporting one file's image
reads that file only.
- `vectorcraft_doc::links::missing_placeholder` draws the placeholder: a
light tile, crossed out, as SVG import shows for a missing file.
Tests: reader tests for the placement, the image keys and the cases left
out, an end-to-end test of a legacy file with a linked image, a test of
a file with a PDF part, and a fuzz case for damaged files with `XG` and
`XF`. The new note has a row in each catalog that translates the
placed-file note.
`.ai` and EPS editing-data import now reads object tags
(`/identifier (string) XT`) and applies each one to the object before it,
whatever kind of object it is. The `AdobeURL` tag sets the object's URL.
Every other tag is added to the object's data in order, up to 64 per
object. A tag with no object right before it, with an empty identifier,
or with an identifier or string longer than 64 KiB is ignored, and so
are tags in a pattern's or brush's art. A clipping path keeps its own
tags; the copy that paints its fill gets none.
Before, a tag on art that shows was an operator the reader did not know,
so it stopped the editing data from being read, and brush art holding a
tag was not read, so the brushes using it were left out.
An image's tags follow the `XH` that ends its data, and the state written
after a group or a gradient mesh is still theirs when their tags come
first. When a drawn look stands for an object whose style is not found,
the look keeps the object's note, URL and data, and a live blend keeps
those of its drawn steps.
The editing copy for other apps now writes linear and radial gradients and
grid patterns as themselves instead of as average colors and cut tiles.
- Gradients the art uses are defined in the setup (`n Bn`, then
`%AI5_BeginGradient` … `Bd`, the stops as `Bs` with their opacity and
midpoints, `BD`), and gradient swatches nothing uses in a non-printing
block. Stops keep gray, CMYK, RGB and spot colors at a tint. A
gradient that isn't a swatch gets a name that no swatch or pattern of
the document has.
- Each fill or stroke with a gradient is an instance around its painting
operator (`Bb`, `Bh`, `Bg`, `Xm`, `Bm`, `Bc`, `BB`), on a compound
path's last subpath and on clipping paths too. `Bg` places the gradient
relative to the path: a linear one by its angle and its start and length
as fractions of the path's extent along it, a radial one by the matrix
that takes the unit circle onto its extent ellipse, its center as
fractions of the path's bounds in that circle's space and its radius as
a multiple of the one the center's distances to the right side and to
the bottom give. In a pattern's tile the placement is mirrored top to
bottom.
- Patterns whose tiles make a grid and hold their art are defined with
`%AI3_BeginPattern` … `E`, the tile's box first, and fills and strokes
paint with `p` and `P`; gradient and pattern swatches are in the palette.
- Freeform gradients, gradients along or across a stroke and gradients
without stops, with more than 256 stops or without extent are written
as their average color, and other patterns as their tiles cut to the
shape, each with a warning. Gradients that dither or mix perceptually
are written as classic ones, stops linked to global process colors as
their colors, and pattern swatches without the placement that moves,
turns or scales their pattern, with warnings.
- Reading: an unpainted box that a pattern's definition marks as its
tile's box (`AIPattern_Editor_Backing_Tile_Rect`) is no longer read as
art, and a linear gradient whose stops all lie at one place keeps each
stop on its side.
The definitions, instances and patterns follow sections 3.4, 3.5 and 14
of the version 7 specification
(http://mercator.elte.hu/~saman/hu/okt/AI7FileFormat.pdf). The stop
opacity, `Bg`'s placement and the marked tile box follow the newer form
that current .ai files carry, which that specification predates.
Each of these is written in the form VectorCraft's .ai reader reads, and
the tests read the written data back through that reader.

Selection Tools add-on: addon.select.byLinkStatus selects the image
objects and placed documents whose link is linked, embedded, missing or
modified (one status or several), as links.list reports it. Optional ids
limit the search, add adds to the selection, and zoom runs the existing
Zoom to Selection in the desktop app. Objects that are hidden, locked, on
a template layer or outside the isolated group are left out and returned
with the reason. Only the selection changes.
Select Linked / Embedded / Missing / Modified are in Object > Plug-ins >
Selection Tools and the Links panel menu. Each is off when no image has
that status, and Shift adds to the selection. Select by Link Status...
lists the images with name, status and format, with a name search, a
status filter, checkboxes with All / None and Zoom to Selection. The
status bar says what was selected and how many were left out, with
plural rows in every catalog.
Tests: engine (statuses, ids, add, zoom, skip reasons, bad params),
command sweep, and UI (message, list filtering, menu items, Links panel
menu, headless dialog frame). Docs: mcp, target-app-parity, ui-parity,
roadmap.

A document tab dragged sideways along the tab strip moves its document to the
place an insertion line marks; the current document stays current. Dragged
above or below the strip, the tab still tears off into a floating window. The
views Window > New Window opened move with their document, and each document
keeps its own zoom, centre and artboard.
The move is the engine command `document.move {from?, to}`, so the control
channel, MCP and recordings reach it, and a replay moves the document before
the steps recorded after it. `sync_views` keeps the views with their documents
by uid when the documents change order.

A Type Tools add-on command (Object › Plug-ins › Type Tools › Release Type on a
Path…, `addon.type.releasePath`): each selected type on a path becomes point
type with the same runs, character and paragraph attributes, on one straight
line whose baseline starts where its first character sat, and the plain path
it was set on, with its exact shape and transform, in its layer and stacking
place, with no fill or stroke. `mode` keeps both, the path only or the text
only; `keepOriginal` leaves the type on a path and adds the released objects
above it. Other objects are left alone, nothing to release makes no undo step,
the run is one undo step and the released objects are selected. The command
dialog previews it as Type on a Path Options does (#5360): Cancel leaves no
history, OK is one step. Tests, command_sweep cases, catalog rows in all 26
languages, docs/mcp.md and the parity docs (beyond Illustrator: scores
unchanged).

addon.pathtools.cornerSet takes `every` ("all", "odd" or "even"; default
"all"), which keeps, of the anchors already chosen (named, direct-selected
or all), only the odd- or even-numbered ones, counted along each path from
its first anchor as number 1. Anchors that take no corner still count, so
the pattern follows the path's anchor order on open and closed paths; when
nothing is left the command says so. Unknown values are refused.
Object › Plug-ins › Path Precision Tools › Set Corners… (also a button in
the Anchor Inspector's Corners section) opens a dialog with Radius, Corner
kind and Anchors (All / Odd-Numbered / Even-Numbered) that previews on the
canvas and commits as one undo step.
addon.select.byArtboards {artboards, relation} in a new Selection Tools
add-on. Overlapping is All on Active Artboard's test, now one shared
helper (select::on_artboard); Fully inside is within one artboard, edges
included; Fully outside is on none. Objects are those Select All takes.

The editing copy of the art that a PDF-compatible .ai carries now holds:
- Transparency: `mode opacity isolate knockout shape Xy` (the blending
mode's number, Knockout Group 0 off, 1 on, 2 neutral), written when it
changes: in a path's paint after its colors, before a guide, and after
a group's end followed by `0 0 Xd` and `6 () XW`. A group without
transparency of its own ends `9 () XW`, and a group's name comes
before its state block. A layer's transparency follows its art: `Xy`,
`0 0 Xd`, `7 () XW`, `LB`.
- Clipping groups as `q`, the art, the clipping path or compound path last
with `h` (or `H`) and `W` before its painting operator, `Q`, as section
5.6.2 of the version 7 specification shows them
(http://mercator.elte.hu/~saman/hu/okt/AI7FileFormat.pdf). A clipping
layer whose clipping object is a path or compound path sets the last
`Lb` flag and writes its clipping path last.
- Opacity masks as an `AI9_Mask` entry in the object's dictionary: the
mask's art between `X=` and `X+`, and Clipping, Inverted, Disabled and
Linked.
Before, clipping groups were written as their art cut to the clipping
path, and transparency and opacity masks were left out. Still left out,
with a warning: the opacity and blending mode of single fills and
strokes, opacity masks on layers (disabled ones too), and opacity masks
nested more than 8 deep. A clipping group or layer whose clipping object
isn't a path or compound path is written as a group of the art cut to
that object, in a layer that doesn't clip, and so are the clipping
groups inside that art. A clipping path's paint that a plain fill and
line can't draw is written as paths inside the clipping, fills under the
art and strokes over it, each side in a group of its own when it has
several, with the clipping path's transparency, lock and hidden state;
the clipping path's opacity mask stays on the clipping path, with a
warning. A clipping group without members is an empty group, and an
empty clipping layer is an empty layer.
Each of these is written in the form VectorCraft's .ai reader reads, and
the tests read the written data back through that reader.
Reading .ai editing data: an `Xy` after a layer's last group or compound
path, followed by the layer's `7 () XW`, is the layer's (a following
`6 () XW` keeps it the group's); groups, compound paths and layers keep
Opacity & Mask Define Knockout Shape.
The `.ai` option `editingData` and docs/file-format-parity.md describe
what the copy now holds.
A blend's record in the editing data holds its Blend Options spacing.
Word 1 is the spacing: 0 is Smooth Color, 1 is Specified Steps and 2 is
Specified Distance. For Specified Distance, word 2 is the distance in
points as a 32-bit float. The reader took only records whose word 1 is
1, so every Smooth Color and Specified Distance blend came in as its
drawn steps.
A Smooth Color or Specified Distance blend now opens live with that
spacing where VectorCraft lays out as many steps between each pair of
keys as the file draws, in the same places and colors. Otherwise it
keeps its drawn steps with the existing note. The distance is read as
the shortest decimal that reads back as the stored float. The steps are
counted before anything is laid out, and a blend takes from the
import's budget only when its count matches. Specified Steps blends
are read as before, with the steps counted from the drawn ones.
Tests: import::ai::tests::a_blend_keeps_its_spacing,
a_blend_of_three_keys_keeps_its_distance_between_each_pair,
a_blend_whose_spacing_doesnt_lay_out_its_steps_keeps_them,
import::ai::blend::tests::records_say_their_spacing,
a_blend_takes_from_the_budget_only_when_it_is_laid_out,
a_distance_past_the_keys_lays_out_no_steps, and the fuzz case
ai_blend_spacing_never_panics.
A built-in Type Tools add-on (Object › Plug-ins › Type Tools › Text Tweaker…,
`addon.type.textTweaker`): size, baseline shift, rotation, horizontal or vertical
scale, tracking, leading or stroke weight go from a start value to an end value
along a straight ramp, an ease, a bow, a spike or at random with a seed, set as
the Character panel sets them, while the text stays live. One undo step, a
dialog with Preview, catalog rows in all 26 languages, docs/mcp.md and the
parity docs.

- Drag strokes, fills, characters and effects to move them, or drop them
on the Duplicate or Delete button
- Select several rows with Shift/Cmd-click and move them as one block
- Delete and Backspace remove the highlighted rows, not the selected art
- Row links open their panel (Stroke, Character…) as a flyout
- Stroke weight spinner follows Units > Stroke
- Transparency panel edits the active fill's or stroke's opacity
