With repeated names numbered when a brush library is read, a stroke that
names a repeated brush draws the first brush of that name, and a later
brush of the name is read as "Name 2". Three tests built a library with a
repeated name and expected the later brush:
- Document Info lists a name two stored brushes share with the first
brush's type (art), not the last one's.
- The two render memory tests add their own `Dots` scatter brush beside
the default library's `Dots`. They now remove the default `Dots` first,
so the stroke draws their brush.
- The .ai writer test that leaves out a Pattern brush "X" gets the
Calligraphic brush after it back as "X 2", the name it had in the
document.
Edit > Edit Colors > Convert to Indexed Color... (edit.colors.toIndexed)
stores the embedded images in the selection as indexed-color PNGs: a
palette of at most 256 RGB colors, each pixel the index of one. The
dialog previews live and OK is one undo step.
- The palette is chosen as for a PNG-8 export (selective, perceptual,
adaptive, web, gray, black and white), as evenly spaced levels of red,
green and blue (uniform), or from the document's swatches. Dithering
is diffusion, pattern, noise or none, with an amount.
- Pixels under half opacity become one transparent entry; the others
become opaque in their own color. Linked images, colorized images and
color glyph images keep their pixels.
- An image that is already an indexed PNG and would show the same pixels
is left as it is, and no undo step is recorded when no image changes.
- An image of more than 134,217,728 pixels (33,554,432 in the web app)
is refused, read from its header before decoding.
- With Select All, locked and hidden objects that hold an image that is
not an indexed PNG yet are counted in notChanged, without converting
them.
- The quantizer gains quantize_to, which maps pixels to a given palette.

A Transform effect whose result would pass the geometry budget (2 million
anchors or 8 million lines drawn) is left out and the art stays where it
was, but the raster effects listed before it still scaled and moved with
it: before a Transform effect that scales the art 1000 times, a Drop
Shadow's offset grew 1000 times and its blur went to the 1000 pt limit
around art that had not moved, and Expand kept those values.
The geometry pass now notes each Transform effect that moves the art once
and that it leaves out, in the Carry it already returns, and
Carry::hide_skipped hides those effects in the list the raster effects
are read from. The canvas (a path's own effects and its fills' and
strokes'), its bounds, bake (SVG and PDF export), shape art, Expand,
Expand Appearance and Outline Stroke use it, and a fill's Transform
effect inside a piece no longer scales the effects before it when the
budget leaves it out. The budget itself is unchanged.
A path drawn as its own art inside a group whose geometry effects run
after its members' own read its object effects whole. The reshaping pass
now notes a Transform effect that no path in the art took past the
budget, and the member's art hides it before its raster effects are read.
The bounds skip the extra geometry pass when no raster effect could
follow a Transform effect, and painted_reach runs it once for both
measurements.
An envelope or the Warp effect cuts an image into triangle pieces that
reach a little past their edges, so neighbors overlap and no seams show.
On an image with alpha, the overlap drew that alpha twice: a 50% image
came out about 75% opaque along every cell edge and diagonal.
- The pieces now form a knockout group, and each piece is marked as a
warp piece (`warp_piece`) whose knockout shape is its whole triangle,
so where pieces overlap only the top one draws.
- The canvas knocks each piece out by its triangle at full coverage.
- SVG and PDF draw the pieces of a partly transparent image (its pixels,
opacity, color mask or colorize paint) through one mask each, of the
later triangles that reach it; pixels on a triangle's antialiased edge
come out slightly lighter there. Pieces of an opaque image are drawn
one over another as before.
- SVG writes one copy of the image for pieces cut by opacity masks
(Preserve Shape Using Transparency) too.
- A cell count past the generated-object budget makes an empty group
instead of overflowing.
Docs: docs/target-app-parity.md.
A group's or layer's geometry effects now run after its members' own:
the geometry effects of each visible path and compound path in it and
of their fills and strokes, and a nested group's geometry and
Pathfinder effects, are applied first, at any depth, and the group's
effects reshape the result. A symbol instance's geometry effects run
after those of its symbol's members in the same way. Before, the group
reshaped the members' outlines and their own effects ran afterwards:
a 100 pt square with its own 10 pt Offset Path in a group with a 50%
Transform drew 70 pt wide, and it now draws 60 pt wide. Existing
documents with such groups draw differently.
The canvas, export (including groups that keep their type), Expand
Appearance and the art that Pathfinder operations and compound shapes
take from such a group use the same order. The reply of
effect.expandAppearance names such a group and no longer names the
members whose effects the group's art already holds.
The renderer now drops the art it keeps for a group when a plug-in is
installed or removed and a member of the group has a plug-in effect.
Docs: docs/target-app-parity.md. Not yet: the own geometry effects of
images, symbol instances, paths with a linked opacity mask or a 3D
effect, and nested groups with a 3D effect in a group still run after
the group's.
A live-effect plug-in that paints its pieces draws each piece's brushed
stroke along the piece's path at the piece's stroke width. Culling left
room for brush art from the object's own stroke width around the
pieces, so brush art of a moved or wider piece was cut off at the edge
of the view. Culling now leaves 16 x the piece's stroke width + 8 pt
past each brushed piece, and does so for a symbol instance whose art
holds such a path (measured once per symbol) and for a blend, envelope
or repeat that holds one. Object > Rasterize measures the brush art
drawn along each piece and leaves out the object's own brush art, which
is not drawn.
Groups and layers now leave room for their members' brush art. The
cull bounds of a group or layer united its members' bounds without the
room each brushed member leaves, so the painted bounds of a group, and
the area redrawn when it changes, left out brush art past its members'
strokes. That applied to plain brushed paths as well as painted pieces.
Each member is now measured as the renderer measures it when it draws
the group, in the members of a group with a fill, stroke or adjustment
of its own and in a group with crop marks or Vector Halftone too.
- The link watch and links.updateChanged look at a DCS file's plate files
of their own, so a changed plate file is read again.
- links.update and links.relink apply the file's clipping path to the
images in symbols, graph designs, patterns and masks too. When the new
file has no clipping path, a clip group holding the old file's clipping
path loses that path and stays as a plain group of the image, keeping
its id, name, visibility and transparency. The image keeps that path with its plates to tell it from a
clipping mask made in the document; a clipping path given another fill
rule in the document stays. An even-odd clipping path in the file is
kept as the same area under the nonzero rule.
- links.update and links.relink return the swatch warnings file.place
gives, including two files that add one ink in two colors.
- links.relink with copy fails for a DCS file with plate files of its own.
- file.place answers the image id of a clipped DCS placement as image,
and checks page and crop for a DCS file as it does for an EPS file.
- Print separations and Separations Preview take a spot plate's color
from the document's swatch of its ink, and a reduced image's plates
keep their coverage.
- Show DCS Transparency Interactions counts a transparent DCS image and
characters filled or stroked with a transparent gradient.
- %%PlateFile names keep their spaces, and header bytes that are not
UTF-8 are read as Latin-1.
- A plate program that draws more than one image, art besides its image,
or its image through a clipping path is an error naming the plate
instead of printing the wrong ink.
- Nested clipping paths around the composite clip the image together.
- A kept image with more plates than are read, or more TIFF directories
than its composite and plates, is the CMYK image of its composite
only, not a set of plates cut short.
- swatch.unused counts a spot or process swatch as used only while an
image the art shows has a spot plate of its name.
A geometry effect on a symbol instance's topmost fill now reshapes the
filled shapes of the symbol's art, and one on its topmost stroke reshapes
the stroked shapes, keeping their colors, strokes and other detail. Only
a visible topmost fill or stroke with an opacity above 0 counts. Clipping
paths, guides and opacity-mask art keep their shapes; a group's own fills
and strokes in the art take the effects; a nested instance passes them on
to its own art, except one whose symbol holds the outer symbol.
The canvas, Use Preview Bounds and the drawn bounds, SVG and PDF export
and Object > Expand Appearance use the same art. Expand Appearance is
enabled for such an instance and turns it into an editable group in one
undo step. Bounds measure the art with a dynamic symbol's overrides, as
the canvas draws it.
Existing documents with a geometry effect on a symbol instance's fill or
stroke draw differently: before, the effect drew nothing.
The three envelope ink tests set "Type" in the default family and
unwrapped ink_bounds(). Without bundled fonts, craft-fonts or system
fonts (vectorcraft-effects' tests on a bare Linux host), no face draws
and the effects test panicked at the unwrap.
Each test now adds the Heighttest Sans face built from the bundled
Source Sans 3 (test-fonts feature, now also on vectorcraft-effects'
dev-dependency), sets the text in it, and computes the expected box
from the layout's glyph outlines. It checks that envelope_ink gives
that box as well as the before and after registration boxes, so a
change to the registered measure fails the test.
A Transform effect on a group reshaped its members' paths but left the
raster effects inside it at their own values: a member's Drop Shadow
kept its 10 pt offset under a 200% Transform effect, and with Scale
Strokes & Effects on, it scaled by the mean scale without turning. The
same held for the raster effects of an object's own fills and strokes
under the object's Transform effect.
- A Transform effect that moves the art once now transforms the raster
effects of a group's members (their own and their fills' and
strokes'), of nested groups, of the art of the linked opacity masks
in it and of an object's fills and strokes, after the members' own
Transform effects: sizes scale by the mean scale and a Drop Shadow's
offset turns, reflects and scales. A raster effect that a member's
own Transform effect with copies or random holds back keeps its value
through that effect and still transforms with the group's. Scale
Strokes & Effects does not scale them a second time. A group's or
object's Transform effect that makes copies or moves at random leaves
them as before.
- The canvas, the redraw region, export, Expand Appearance, Object ›
Expand and Outline Stroke read the same values.
- The Transform effect's params text and docs/target-app-parity.md
describe the rule.
When the document does not hold a color mask's masked pixels, the image is
drawn from its own pixels. A live color adjustment now recolors those pixels
and drops the mask on the recolored copy, instead of pointing the image at
the missing masked pixels, which drew nothing and left Expand Appearance with
an image whose pixels were not in the document.
File › Place with Link reads a DCS 1.0 or 2.0 file (an EPS file whose
header names one EPS program per printing plate) as one linked image of
its plates. Each spot plate adds a spot swatch in the CMYK values the
file gives, and the clipping path the file's composite is drawn through
clips the image. document.open, file.place without link or from bytes,
and links.embed refuse a DCS file and change nothing.
- The screen, composite print and exports show the plates mixed into
CMYK. Separations Preview and print separations show each plate on
its own ink; a spot plate prints as its CMYK values when spots print
as process.
- links.list answers the format DCS, and with dcsTransparency marks the
DCS images that are transparent or overlap transparent objects (the
Links panel menu's Show DCS Transparency Interactions).
- swatch.unused leaves out a spot swatch while a DCS image has a plate
of its ink.
- links.update and links.relink read the plates and the clipping path
again, and the link shows as modified when one of its plate files
changes or is gone.
- The plates go on the first plate's pixel grid, grown to hold every
plate where it prints; a plate of another size or position is
resampled onto it.
- A file may name 64 plates, a plate file may be 1 GB, and the plates
together may hold 512 MB of ink amounts. A file naming more plates is
an error.

pattern::tests::kept_tiles_count_the_images_they_could_not_decode
draws a pattern whose art is an image three times and expects one tile
to be rasterized. A tile of art with an image is kept only while
FontDb::global().generation() is the one it was drawn at (Deps::current
in pattern.rs). The render tests that hold adding_fonts() add fonts,
which increases it (tests/fontchange.rs, tests/typeedges.rs,
tests/alternate.rs, tests/colrglyphs.rs and tests/bitmapglyphs.rs).
When one of them added a font between the frames, the next frame drew
the tile again and the test failed with left 2 or 3, right 1. Run with
the tests in tests/fontchange.rs and tests/typeedges.rs, it failed in
23 of 30 runs on main.
The test now holds fonts_steady() and takes its counts from
with_fonts_unchanged(), as the other render tests that count kept work
do. Each run builds a new document, so its first frame does not find a
tile from an earlier run. Run with the same tests, it passed in all 30
runs.
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.
Docs: docs/mcp.md (Spread), docs/target-app-parity.md, docs/gaps.md.
The canvas kept the art of an image whose own fill or stroke follows the
outline of its pixels for as long as the image object stayed the same. When
the document's pixels for the image changed under the same key (Update Link
replacing a preview with the linked file's pixels), the stroke kept the old
outline while hit testing and Use Preview Bounds used the new one. The
renderer now keys that art by the document's pixels for the image too.
- vectorcraft-effects: `follows_image_pixels` names such images.
- vectorcraft-render: `reads_outside` counts them, and the resources key
hashes the address of the document's pixels for them; their walk is not
kept between frames.
- A test places an off-center opaque area in a smaller copy of the pixels
under a turned and reflected placement.
- Docs: the Outline Object params text names every case that keeps the frame
and the 50% cutoff as VectorCraft's own; docs/mcp.md's `effect.apply` entry
for Outline Object, how long an outline is kept and the 16-bit RGBA limit;
docs/target-app-parity.md's evidence lines.
Object › Plug-ins › Image Tools gains Color Mask… (`addon.image.colorMask`),
Remove Color Mask and Apply Color Mask. Color Mask hides colors of the
selected images without changing their pixels. It matches colors as Remove
Background does: the edge color, the corner color or picked colors, with
Contiguous, Match, Tolerance and Softness. The mask is kept with the image
object and saved with the document: its settings, and a PNG of the image's
pixels with the hidden colors made clear, at the source's depth with its
color profile and resolution. It is a VectorCraft addition.
- The canvas (clip groups and white-shape opacity masks included),
printing and separations, PDF (soft masks of CMYK images included), SVG,
EPS, the raster formats, the legacy .ai and .ai editing data, EMF/WMF,
DXF and the flattener draw the masked pixels. A linked image stays
linked, and an output that would refer to its file writes the masked
pixels instead.
- Copy and paste, placing a document and placed documents carry the masked
pixels with the image, under the names they are given there.
- The dialog opens on the selected image's mask settings, with a Preview.
Without settings, the command returns them and changes nothing.
- Setting, removing and applying a mask are each one undo step, and no
step is added when nothing changes. Apply makes the masked pixels the
image's own and embeds a linked image. A mask that hides nothing is only
taken off, and the image keeps its pixels and its link.
- When an image's own pixels are replaced (Update Link, Relink, Crop
Image, a recolor, a linked file read again on open), its mask is made
again for the new pixels, in every art tree and in opacity-mask art.
Crop Image cuts the image's own pixels. When the new pixels can't be
masked, the mask keeps its settings and hides nothing.
- Objects in `ids` that are not images, CMYK images, linked images that
show their preview, images past the decode allowance, masks that would
hide every pixel, and grayscale images colorized with a process color
are refused. The Eyedropper, Object Mosaic, Create Gradient Mesh, Crop
Image's trim and Image Trace read the image's own pixels.
- An image is selected by a click anywhere in its frame, as before.
Remove Background now also refuses a grayscale image colorized with a
process color. Its result has an alpha channel, and a process color is
refused on a grayscale image with transparency.
Docs: docs/mcp.md (Image Tools add-on › Color Mask),
docs/target-app-parity.md.
An object with an opacity mask draws offscreen over the bounds the
renderer gives it. For a live object (a blend, envelope or repeat) those
bounds took in effects in symbol art and brush art inside it, but not a
path's own effects, so with Clip off the drop shadows of a blend's steps
were cut off at the steps' bounds and did not draw where the mask art
leaves them uncovered. The bounds now also take in how far each path's
own effects paint past it.
Effects apply in the order they are listed, so a Drop Shadow, glow, blur,
Feather or pixel filter listed before a Transform effect paints art that
the Transform effect then transforms. VectorCraft drew such an
effect at its own distances around the transformed art: a square scaled
to 200% kept a 10 pt shadow offset. Now the effect follows the Transform
effects after it, with Scale Strokes & Effects on or off: its sizes scale
by the mean scale, and a Drop Shadow's offset turns, reflects and scales
with the art. Effects listed after the Transform effect keep their values,
and Transform Objects off changes nothing.
- raster_effects reads each raster effect through the Transform effects
after it, so the canvas, export and the redraw region use the followed
values.
- Where the geometry effects are applied and removed (Expand Appearance,
baking for export, evaluated groups), the raster effects that remain
carry the same transformation, hidden ones included.
- A Transform effect that makes copies or moves at random leaves the
raster effects before it as they are. Rasterize and SVG filters keep
their options.

The Stroke panel menu's Edit Arrowheads… (stroke.arrowheads.edit) opens
Arrowheads.vectorcraft next to the preferences, creating it with one
example head when it is missing. Each symbol in the file is one head,
listed by name after the built-in heads in both arrowhead menus: it
points right, its registration point is the tip, and its height is drawn
as wide as the built-in heads. The file is read at startup and again
each time VectorCraft saves it; stroke.arrowheads.reload and
stroke.arrowheads.list read and list it.
Arrowhead gets a Custom variant, appended after the built-in names, that
carries the head's name and outline, so a document that uses one draws,
saves, reopens and exports it without the arrowheads file. stroke.set
takes {"custom": name} or the {"Custom": {name, path}} form that
document.inspect reports.
