- `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.
Horizontal type keeps both marks, and the legacy .ai writer writes such
type as text, but the marks were dropped without a warning. Version 7
text has operators for both (section 15.3.4 of the published format
specification): Tv for Roman characters upright in vertical writing,
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.
docs/gaps.md, docs/file-format-parity.md and docs/ui-parity.md still
listed the CNC preset as open after #5500 added it. They now name DXF
Options' Preset menu and dxfPreset: "cnc" on document.exportDxf; VCarve
QA stays open. The ui-parity row also no longer lists native CIRCLE/ARC
export as pending.
VectorCraft could open and place HP-GL plot files but not write them,
so art for a pen plotter or a vinyl cutter had to go through another
program.
Export As, document.export and Export Selection now write HP-GL.
vectorcraft_cad::hpgl::export draws each visible path once along its
own line: a filled shape is its closed outline and a stroked path its
center line. Type is drawn as glyph outlines, a gradient mesh as its
outline, and a symbol instance as its art with its effects and the
instance's stain. Clipping masks cut the art they clip, and the art is
cut at the artboard's edges. Hidden and non-printing layers, hidden objects,
objects at 0% opacity, template layers, guides and placed images are
left out. Coordinates are plotter units (1016 to the inch, y up) from
the artboard's bottom-left corner or its center, and art more than
8,388,607 units from the origin is cut off.
Each color is a pen, in the order the plot first draws in it (up to
255), or a pen table maps each path to the pen of the nearest color.
With Use Artboards every file of the export uses the same numbering.
The pens draw in turn, each in paint order or, with sortPaths, nearest
path first. Curves are flattened to curveTolerance (0.1 pt by default).
hpglVersion "hpgl" writes IN, SP, PU and PD; "hpgl2" also writes the
palette (NP, PC) and each pen's paths as one encoded polyline (PE).
Options are checked, and Export As writes the file with the defaults.
Plots read back by the HP-GL reader give the same lines.
Docs: docs/mcp.md, docs/control-protocol.md, docs/file-format-parity.md,
docs/target-app-parity.md.
Save and Save As as EPS always wrote the chosen artboard as the page and
%%BoundingBox, and the EPS Options hid Use Artboards, so art past the
artboard was left outside the file's bounding box.
The EPS Options of Save As now show Use Artboards with All or Range
under it, unchecked by default. Unchecked, Save writes one file whose
bounding box fits all the visible art, as Export does, without the
artboards' background colors; with no visible art the page is the first
artboard, in its color. Checked with two or more chosen artboards, the
file at the path is the central file of the visible art and each
artboard is also written to <name>_<artboard>.eps beside it. Checked
with one, that artboard is the page of the file at the path, the
behavior Save had since #4293 (mockydevs). The file the document becomes
still carries the whole editable document.
Naming artboards with artboard, artboards or range still turns Use
Artboards on. file.formatOptions now reports it on, with those artboards
as the range, and the Save As dialog opens that way.
Changed default: an EPS saved with Save or Save As, an opened EPS
included, now gets a bounding box around its visible art unless Use
Artboards is checked or the save names artboards; an opened EPS saved
back this way loses the margins its page had. selectedOnly stays an
Export option, and Save refuses it.

File › Open and File › Place refused plotter files: HP-GL/2 files
(.plt, .hpgl, .hgl, .hpg) were not a format VectorCraft reads.
The format table gets a read-only HP-GL format, read by a new
vectorcraft_cad::hpgl module. Each line the pen draws becomes a stroked
path in its pen's color and width, with the line type as a dash pattern
and the line attributes as caps and joins. Circles, arcs, wedges and
Bézier curves are drawn as curves. Filled and edged rectangles, wedges
and polygons (polygon mode) become filled or stroked paths, and encoded
polylines, scaling points, user units and rotation are read. Plotter
units (1016 to the inch, y up) become points, and the artboard holds
what the art paints. Place brings the art in as one group. Older HP-GL
files are read by the HP-GL/2 rules for the instructions the two share.
A file is recognized by its first instructions, after any printer
escape sequences and PJL lines, so a plot file also opens under an
extension no other format reads. VectorCraft's own rules where the
device decides: before the first SP the pen is pen 1, and the hard-clip
limits are 11 x 8.5 in, which P2 takes when the file sets no scaling
points. Labels, symbol-mode symbols and raster images are not drawn,
the input window does not clip, hatched fills are filled solid, and
later pages are drawn over the first; the warnings list each. Objects,
path points and pen widths are capped, and the import fuzzer covers
random, mutated and garbage plot files.
An importer plug-in that lists .plt, .hpgl, .hgl or .hpg now opens
those files only when document.open names it with `importer`.
Docs: docs/mcp.md, docs/file-format-parity.md,
docs/target-app-parity.md, docs/releasing.md.
When the read-only fallback's Save As panel returns a different format, drop the options captured for the original format and open the picked format's normal Save options; an unchanged format keeps its options. Regenerate the file.save entry in the MCP command catalogue.
Opening a .psd or .psb used to give one merged image. document.open now
reads the layer records and builds the document from them. The PSD
import options page
(https://helpx.adobe.com/illustrator/desktop/add-and-import-files/import-from-other-apps/photoshop-import-options.html)
says the option that converts layers to objects keeps as much of the
layer structure as it can, merges the layers of a clipping mask into one
layer and discards hidden layers that require merging, and that Import
Hidden Layers brings hidden layers in. document.open does the same, with
hiddenLayers: true for the hidden layers; layers: false keeps the merged
image.
VectorCraft's own rules:
- Each layer becomes a layer holding its pixels as an image, with its
name, visibility, opacity and blend mode. A group becomes a layer of
sublayers; a Pass Through group is not isolated.
- Clipped layers show where the layer below has pixels. That layer's
fill opacity fades only its own pixels. Layers clipped to an
adjustment layer, or to a fill that stores no pixels and isn't drawn,
show over the whole canvas.
- A layer mask becomes the layer's opacity mask, its default color and
invert flag applied; a disabled mask is kept, switched off.
- Fill opacity multiplies the layer's opacity.
- Layers and groups in Dissolve, Linear Burn, Linear Dodge, Vivid Light,
Linear Light, Pin Light, Hard Mix, Subtract, Divide, Darker Color and
Lighter Color are merged with the layers below, whether or not they
hold transparent pixels; Color Dodge, Color Burn and Difference keep
their mode. A merged Dissolve layer's pixels are opaque or
transparent, in a pattern of each layer's own.
- A solid color fill layer that stores no pixels and has no vector mask
comes in as its color (RGB, CMYK, Grayscale, Lab or HSB).
- A layer name stored only as a Pascal string, without its Unicode
name, is read as Mac Roman.
- Adjustment layers, fill layers that aren't drawn, layer effects that
are switched on, knockouts and vector masks are not applied; the
warnings count them.
- A merge whose canvases need more memory than allowed leaves the layer
alone, in the Normal mode or unclipped, with a warning.
This changes what opening a layered PSD does. Batch Trace Folder passes
layers: false, so a PSD is still traced as its merged image. A file
whose layers can't be read, or whose layers and merges need more memory
than allowed, opens as the merged image with a warning.
Lengths, counts, nesting, decoded pixels and the canvases merges make
are bounded. Zipped 32-bit data with prediction is now read, in layers
and in the merged image. import_fuzz gains a case that mutates the PSD
and PSB samples and opens them with their layers. The PSD reader's new
error messages have rows in every catalog.
Docs: docs/mcp.md, docs/target-app-parity.md, docs/file-format-parity.md,
README.
A plain Save that the location refuses (read-only filesystem or permission denied) now opens Save As with the name filled in, instead of ending in an error dialog. The refusal travels as a typed engine error (READ_ONLY_LOCATION), so the control protocol and MCP still return an error and never open a panel. Recovery failures, explicit destinations, a busy picker and Close/Quit keep their existing flow.
Closes#6146
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.

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.

The text document writer wrote a type stroke's paint and weight but not
its cap, join or miter limit, which .ai import reads since #6500 (keys
61, 62 and 64). A file saved here and opened again came back with butt
caps, miter joins and a miter limit of 10, and the save reported those
attributes as left out. A stroked run now writes the three keys,
numbered as PostScript numbers caps and joins, with the miter limit as
import takes it back (1 to 500, else 10), and they no longer count as
lost. A run without a stroke no longer counts them as lost either: they
draw nothing.
Follow-up to #6472.

A layer's Lb colour index was its position in LAYER_COLORS, but the file
numbers Magenta, Cyan and Yellow 4, 5 and 6 where LAYER_COLORS has Yellow,
Magenta and Cyan. Save (editing copy and legacy) and open now map the index
both ways; LAYER_COLORS keeps its order and the other 24 presets are unchanged.
While an envelope's contents are edited, the editing data keeps its mesh
in the envelope's dictionary. In some users' files that mesh lies away
from the drawn art by a plain move, the contents sitting with the drawn
art, as if the mesh hadn't followed the envelope when it moved. The
envelope then drew its contents elsewhere, failed the drawn-art check
and kept its drawn art. Nothing in the dictionary records the move, and
no envelope saved outside Edit Contents was found displaced.
A mesh or top object saved in Edit Contents (and a warp of type tried
on its saved grid) whose mesh draws the contents as large as the drawn
art, within half a point over width and height together, but further
from it than that, is now tried again after every other way, with one
more of the import's checks, its mesh moved by as far as the drawn
art's box lies from the box of what it draws. The drawn-art check, the
budget and the page comparison decide as before, so an envelope that
opened live before opens the same way.

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.

With Distort Appearance, the stroked candidate for type in an envelope
mapped from the type's bounds with strokes, which for a stroke on the
type's appearance (or on a group round it) reach as far as a miter join
may at a corner, the miter limit times half the weight. In users' files
the drawn art maps from the glyphs grown by what the strokes paint along
a side: half the weight of a centred stroke. The candidate now uses that
box. Character strokes keep the measure the type's bounds with strokes
already give them (they have no miter allowance), and other objects in
the contents keep their bounds with strokes.

The text document reader set a type stroke's paint and weight but never
its cap, join or miter limit, so every stroked text object imported from
a .ai or EPS editing copy drew with a miter join at a limit of 10. Type
the file strokes with round joins, or with a miter limit of 4 or less,
drew long spikes at its sharp corners.
Keys 61, 62 and 64 of a run's character attributes (the run, its
character style, then the document defaults) are now read as the
stroke's cap (0 butt, 1 round, 2 projecting), join (0 miter, 1 round,
2 bevel) and miter limit, as PostScript numbers caps and joins. In the
users' files the page strokes type with exactly these settings. Other
values keep the defaults, a miter limit is capped at 500, and type
without a stroke keeps the defaults.
- ate.rs: Style reads the three keys and char_style passes them on,
with a unit test over defaults, character styles, run overrides,
hostile values and unstroked type.
- tests_native.rs: an imported story with round, bevel, default and
unstroked runs.
- docs/file-format-parity.md: revision row, status line, one line on
the mapping.

A variable font's CoolTypeFont record in the text document now carries
/4 (its design vector, one 16.16 value per fvar axis) and /5 (its
version string), and the font set keys on name plus design vector, so a
named instance or a run's own axis setting no longer opens at the
font's default instance. Static fonts are unchanged.

The put-back after a failed page check replaces each live envelope with
its drawn art in one go, which fails as a whole when one envelope lies in
another's art: only the outermost are put back now. A live envelope of
type removes its hidden type only once it has found the drawn art it
replaces. The file format docs lose a revision row left twice by a rebase.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The file-format revision row for #3179 says that the page check weighs
a live envelope of type as the art it draws, that layers used though
they don't draw as the page leave envelopes of type their drawn art,
and that a slot bound to a visibility variable keeps it too, and lists
the new tests. The parity assessment's evidence says the same, and
the change gets its row and status entry there.
Part of #3179.

An envelope whose contents hold type kept its drawn art, with the type
hidden, because the type is laid out from the text document only after
the layers are read. It now waits for that, as warped type does: once
its text slots hold their type, the envelope is made of that type and
drawn by VectorCraft's own rule, and where it draws as the drawn art the
file saves (the same check and budget as other envelopes) it takes the
drawn art's place, with the type visible and editable in Edit Contents.
The hidden copy of the type goes.
As other live envelopes are, it is held to the page: when the layers
with it don't draw as the page, its drawn art and hidden type are put
back. A .ai whose layers would open alone, without its PDF part, now
waits on the PDF part when an envelope of type is in them; where none
opens live, the layers open alone as before. Layers built without a page
leave envelopes of type their drawn art.
Elsewhere it keeps its drawn art and hidden type, with the note: type in
a font that isn't available, a slot without made type (threaded, bound
to a text variable, a wrap object, type a look draws), an envelope that
doesn't read, no check left, or one that draws differently. Envelopes in
a symbol's or a pattern's art keep their drawn art.
Part of #3179.
