VectorCraft does not run scripts written for the reference app, and
File › Scripts held only the disabled Other Script…. File › Scripts ›
Check Script… picks a .jsx, .jsxinc or .jsxbin file, reads it without
running any of it, and shows a report: what the script needs (the
script language's own objects, the document model, files, menu
commands, dialogs, or features only the reference app has), what it
would do outside the document, the menu-command strings it passes, the
document-model member chains and type names it uses, its directives,
the files it includes, and the problems that would stop it loading.
Copy Report copies the report as JSON. File › Open and drag-and-drop
show the report for those files too.
- vectorcraft-scriptcheck, a new Standalone crate with no
dependencies, holds the checker: a lexer for ECMAScript 3 with E4X
literals and the #name and //@name directive lines, and an analysis
of the tokens that follows variables, function scopes and the files
a script includes. It never recurses: open brackets, the levels of
an XML literal and the function bodies being read are kept on stacks
capped at 4,096. It reads at most 8 MiB of a file and 32 MiB with the
included files, follows 64 included files 16 deep, looks up at most
1,024 paths for them, keeps 1,000 entries in a list, tracks 1,000
variables holding member chains and 1,000 holding File objects, and
cuts echoed text to 120 characters. A compiled script is reported as
compiled and isn't read.
- script.check (engine, a query) takes path, data or dataBase64. With a
path and includes: true, it reads the files the #include lines name
from inside the script's folder, through the automation read root,
and when the script or one of those files assigns a member chain or a
File object to a variable, the check treats the variable as holding
it in every file. It doesn't follow absolute names, names, folders or
links that lead out of the folder, names or folders longer than 4,096
bytes, or JSINCLUDE, and it reads only regular files.
- ui.checkScript shows the report (dialog scriptCheck). File › Open
lists Scripts (.jsx, .jsxinc, .jsxbin) and sends a script's path to
script.check, which reads at most 8 MiB of it.
The language rules come from ECMA-262 3rd edition and ECMA-357 2nd
edition. The directive, platform and document-model root names come
from the public JavaScript Tools Guide and scripting guide pages that
catalog.rs cites by URL, and executeMenuCommand, doScript, loadAction,
unloadAction and selectTool come from the public forum posts cited
there; only names are used. Every script in the tests is written from
scratch with invented names.

document.open (and file.newFromTemplate) with a path relative to the
working directory took the SVG's folder from Path::parent(), which is
"" for a bare file name and was then dropped, so relatively linked
images were "not found" (and, linked by their bare name, not listed in
missingLinks either). A relative path is now made absolute first: its
folder is the working directory, as for the absolute path.
vectorcraft-cli convert printed only the export's warnings; what reading
the input left out now comes as importWarnings.
Fixes#1604
A character style's OpenType features took nine tags. OtFeatures now
also keeps ss01-ss20, salt, titl, pnum, lnum, sups and subs (off by
default, one bit each in `extra`): they are accepted by the type
commands, stored with the style and passed to the shaper, so a font
that has them uses them.
The Affinity import test used ss01 as its example of a feature kept but
not rendered; it now uses cv01 for that (character variants still
aren't rendered) and keeps ss01 as one that is.
Fixes#1607
Lock › All Artwork Above and Hide › All Artwork Above went through the
objects above each selected object in its top-level layer, one selected
object at a time. For each object they looked up in a list whether it
was selected or already found, and they computed its bounds again for
each selected object below it until one overlapped it. With 100 tiles
selected under 25,000 rectangles, a release build of vectorcraft-cli
took 6.4 s for Lock, and with all of 5,001 objects selected it took
8.8 s and locked nothing.
The commands now go through each top-level layer that holds a selected
object once, and check each object that is not selected against the
bounds of the selected objects below it. The selected objects and the
objects found are kept in sets, and each object's bounds are computed
once. The objects they lock or hide, the count, the selection and the
undo step are the same as before. On the same documents Lock now takes
under 0.1 s.

Gradients (params `gradients`, a checkbox in the panel for Grayscale and Color;
off unless asked for): an area whose colour changes evenly along one direction
is traced as one path filled with a linear gradient, not as bands of flat colour.
Gradients are found before the palette is made, so no colour is spent on their
bands: a connected run of smoothly changing pixels is a gradient when a plane
fits each colour channel with all three sloping the same way, the colours along
that way are at most six stops with ramps between them, and painting them back
gives the area's own pixels. Flat colour, soft edges between flat colours and
shading that goes two ways are left as they were.
The harness gains two linear-gradient inputs with known lines and stops, and
measures whether each is found, the angle of its line and the colours of its ramp.
Auto Grouping (params `autoGrouping`, a checkbox in the panel; off unless asked
for): each traced path that has others inside its outer contour comes out in a
group with them, the path first, nested as deep as the picture is. The path that
covers the whole image is nobody's group.
The grouped result paints the same picture: where paths can overlap (stacked
layers, Flat Logo, strokes) a path only joins a path below it, and only if that
moves it under nothing that shares any of its box.
The harness measures three presets with the option on ("grouped %"), painting
them in the grouped order.
With paths selected but every offset empty (an inset larger than the
shape), Offset Path failed with "select paths", sending the user to
look for a selection problem. It now says the offset leaves nothing of
the selected paths; "select paths" stays for selections without paths.
Fixes#1590
Commands whose description takes `ids` (operate on these objects;
default: the selection) failed with "nothing selected" when objects
were given but none was selected: execute checked their `enabled`
predicate against the selection, with an exception for edit.clear only.
Of the 220 commands mentioning ids, 48 were refused so; their run
already used the ids. execute now evaluates `enabled` with the given
ids selected and puts the selection back, so each predicate keeps its
meaning (Make with Top Object still needs two objects).
Fixes#1575
The public Pathfinder documentation says Trim and Crop remove any
strokes, and Merge removes them and merges same-coloured fills. The
pieces kept every stroke, and Merge, grouping by the whole style, left
same-filled objects with different strokes apart. The three now drop
stroke layers before styles are compared.
Fixes#1570
Shapes (params `shapes`, a checkbox in the panel; off unless asked for): a filled
outline that is a circle, an ellipse, a rectangle or a regular polygon comes out
as that live shape. A shape is only made when every point of the traced outline
lies within 0.5 px (0.2% of the shape's size, if more) of it; an ellipse whose
radii differ by less than twice that is a circle of its area.
The outline before fitting: a corner's own pixel no longer pulls the two edges
that meet there, and a one-pixel step between two long edges is the corner where
they meet. Sharp corners kept: Default 69% -> 76%, the colour presets 86% -> 91%.
The harness gains plain-shape inputs and "shapes %".
Against the documented panel (https://helpx.adobe.com/illustrator/desktop/manage-objects/traces-mockups-symbols/image-trace-panel-options.html):
- Ignore Color: "Ignores a specific color while tracing. Use the color picker to selectively ignore a color."
The panel's Ignore White is now Ignore Color with a colour button beside it (white until another colour is
picked); `imageTrace.make` takes `ignoreColor: "#rrggbb"` beside `ignoreWhite`, and leaves out the palette
colours within about 30 levels of it. Documents saved before have no such setting and ignore white as they
did. Flat Logo mode leaves out white only.
- Auto Color ("Creates a posterized image from a photo or artwork"): Color mode with the Automatic palette.
- Outline ("Simplifies the image to black outlines"): Black and White with Create: Strokes and no fills.
- The Outline preset's name is translated as a preset's name, not as the Outline view's.
Measured (docs/image-trace-quality.md): Auto Color on flat art is 0.140 px off on average with 4.0 paths (16
Colors: 0.141, 4.2). Outline on the line inputs, the first measure of Create: Strokes: 0.310 px off on average,
1.84 at worst, 81 anchors for 5 lines (Line Art's filled outlines: 0.055, 0.96, 46).
A drag near an anchor refitted the whole segments on either side of it, so a
short drag over a small bump on a long side turned the side into a curve from
end to end. The segments leading into the anchors under the drag are now split
where they enter the tool's reach, and only what is in reach is refitted.
An image whose decode needs more than the 2 GiB allowance (512 MB on the web) is not drawn.
A raster export says so since #1517; on screen it was still blank with no word. Open and
Place now carry a warning for it, and the Links panel's row a note (links.list: note).
Paste read PDF only from the Windows clipboard and EPS nowhere, so on macOS a copied
equation or drawing pasted nothing new (the last thing copied in the app came back).
- macOS: the pasteboard's PDF, EPS and SVG are read, ahead of text and bitmaps.
- Windows: EPS is read beside PDF.
- Everywhere: an .eps file copied in a file manager pastes.
- clipboard.importEps loads an EPS into the clipboard as document.open reads one.
A group has no paint of its own, so a compound path made of one (outlined type) had none
and drew nothing until a fill was set. The paint now comes from the backmost path, or
from the compound path that painted it.
Offset Path, Outline Stroke, the Pathfinder panel, Clean Up, Make
Blend, Rasterize and the other commands that #1429's table marks 3,
except Split Into Grid, added, removed or replaced their objects one at
a time, and so did Remove Anchor Points, Redefine Symbol and the
removal of Shaper groups whose source art is gone. Each insertion or
removal moved the later objects of the layer or group. The lookups by
id that followed walked the tree, and every fourth walk rebuilt the
lookup cache. On 25,000 rectangles a release build of vectorcraft-cli
took 29.1 s for Offset Path.
These commands now make their edits with Document::wrap,
Document::insert_beside and Document::remove_many, in one pass over the
children of each layer or group, and Outline Stroke and Expand write
each new object into the place of the object it replaces. A list that
holds an object twice, or an object and another inside it, and that was
edited without an error before, is still edited one object at a time.
The documents, selections and undo steps are the same. On the same
rectangles Offset Path now takes 1.3 s.
Docs: docs/target-app-parity.md.
These commands removed, moved or copied one row or object at a time:
the Layers panel's Delete Selection, Duplicate Selection, Collect in
New Layer, row drags, Merge Selected, Flatten Artwork and Release to
Layers, and Cut Artboard, Duplicate Artboard and the Artboard tool's
Alt-drags that copy art. Each edit moved the later rows of the same
layer or group to other indices. The next lookup by id then walked the
tree, and after every fourth such walk Document::index_path rebuilt
the whole lookup cache. Release to Layers also walked the document
twice for each new layer to name and color it. With 25,000 rectangles
in one layer, a release build of vectorcraft-cli took 11.9 s for
Duplicate Selection and 17.7 s for Release to Layers.
The commands now remove, move and copy the rows in one pass over each
layer or group, with Document::remove_many and Document::wrap, and
with copy_above, the copy pass of duplicate_in, which Duplicate
Selection and the artboard copies now share. Release to Layers names
its new layers from one walk of the document. Merge Selected checks
the target layer's objects against a set of the listed rows, and
Delete Selection checks the top-level layers against such a set. In a
document whose ids are unique, the rows keep their order, new rows and
layers take the same ids, names and colors, and the selection, the
undo step and the journal are the same. A release build with this
change takes 98 ms for Duplicate Selection and 26 ms for Release to
Layers.

The renderer decoded images with the decoder's default 512 MB allocation
limit, so a 300 ppi roll (6614 x 59055 px, 1.56 GB as RGBA) that opens and
exports to PDF fine drew nothing in a raster export - a fully transparent PNG,
exit code 0, no warning. It now decodes with the allowance opening has (2 GB,
512 MB on the web), shrinks an image past a pixmap's 65535 px side to fit
instead of dropping it, and counts any image it still can't decode: a raster
export that drew fewer images than it should says so in its warnings.

Trim decoded the image with the decoder's default 512 MB allocation limit, so
a 300 ppi roll (6614 x 59055 px, 1.56 GB as RGBA) that opens fine failed with
"the image's pixels can't be read". It now decodes with the allowance opening
already has (MAX_RASTER_ALLOC: 2 GB, 512 MB on the web). A CMYK image, kept as
its ink amounts, has no alpha: trim leaves it alone (trimmed: false) instead
of failing to decode it.
