A new reader, written from the ZSoft PCX Technical Reference Manual, decodes
the run-length encoded scan lines of 1-bit images in the header palette's
first two colors (black and white when the version has no palette or the two
colors are the same), 1-bit images in two to four planes and 4-bit images
with the header's palette (the EGA colors for versions 0 and 3), 2-bit CGA
images in the colors that the header's CGA background and palette settings
pick, 8-bit images with the 256-color palette after the image data (gray
levels without one) and 24-bit images in three planes. The image is stored as PNG at the resolution of the header's HDpi and
VDpi fields.
Open and Place list PCX, and pasting a copied .pcx file and Glass's Load
Texture… read it by its header. A file of another depth or plane count, one
cut short and one whose pixels as RGBA pass the pixel allowance are refused
with a message before its pixels are decoded. The desktop packaging does not
associate .pcx files, and no export writes them.

Tracing a photo or a large image ran inside imageTrace.make on the UI
thread, so the window froze for as long as the trace took, with nothing
to say it was working.
A trace the user asks for (Object > Image Trace > Make and Make and
Expand, the task bar's Image Trace, the Image Trace panel's Trace and
presets) now runs on a thread of its own, as heavy plug-in filters do.
The status bar says so, and after 0.4 s a progress window shows how
many of the image's colors are traced, with Cancel and Continue in
Background (imageTrace.cancelRuns, imageTrace.hideRuns).
The result goes back to the command it was prepared for
(cmd::TraceRun, Traced::hand_in), which takes it only for the same
object, image and settings, so the edit is one undo step as before. A
newer trace of the same object replaces one still running, and a trace
whose image or settings changed meanwhile changes nothing. The control
channel, MCP, scripts and the web trace at once, as before.
The tracer reports its stages and color layers to a callback and stops
when it says so (trace_watched).
The reference app's Flare tool rotates the rays as the center is dragged
out, Shift constrains them to their original orientation, and Space
held moves the shape being drawn. VectorCraft's Flare tool drew the
rays in one fixed orientation and ignored Shift and Space.
shape.flare takes rotation (degrees, clockwise), which turns the rays
about the center and leaves the halo, the center and the rings as they
are. While the center is dragged out, the rays turn with the pointer,
as a polygon's first corner does, and a drag straight up leaves them
unturned. Shift keeps them unturned, or turned by General › Constrain
Angle as a polygon drawn with Shift is. Space held during the center
drag or the drag that places the rings' end point moves the flare at
its current size, and the drag goes on from there when Space is let
go, as with the shape tools.

With nothing selected, a click with the Eyedropper picks up an object's attributes and an Alt/Option-click on another object applies them, as the reference app's Eyedropper does. Alt-click only copied from a selected object, and with nothing selected it failed. The session now keeps a copy of what appearance.copyFrom picked up last, and a reversed copy with nothing selected applies it.
Preview, Embed ICC Profiles, Create PDF-Compatible File and the other VectorCraft Options went back to their defaults for every document not saved yet. A native Save or Save As now records the options it used in the preferences (not the artboards it picked, nor Use Compression, which its preference decides), and file.formatOptions offers them for a document not yet saved as a native file. A document saved before keeps its own.
While an opacity mask is edited the Layers panel lists only the mask, so a new layer was added where no row showed it, and only the panel's layer count went up. Both commands are now disabled then, as isolation commands already are (outside_mask_editing).
- In `shaper::refresh`, replace full document walks with `changed_shaper_groups`,
diffing `before` and `after` layers and short-circuiting on pointer-equal (`Arc::ptr_eq`)
subtrees in O(1).
- Return whether Shaper groups rebuilt or modified artwork (`Result<bool>`),
allowing `Session::edit` to skip the second `cmd::objects_on_path::refresh`
call when no artwork was modified.
- In `textwrap::refresh`, check pointer equality on layers against `before.layers`,
skipping untouched layers in O(1) and checking only modified layers.
With a layer selected, Object > Hide > Unselected Artwork hid every object
on that layer, since the selected layer was dropped from the objects to
keep. The objects of a selected layer now count as selected.
While Lock Guides is on, a group that held a guide path was hidden whole,
which hid the guide with it. Guide paths now count as selected, so the
command keeps such a group visible and hides its other members one by one.
svg_darkness_uses_rendered_shadow_in_non_srgb_working_space runs itself
again in a child process with --exact and checked only the exit status.
libtest exits 0 when --exact matches no test, so a rename of the test
would have left the parent passing without running the non-sRGB check.
The parent now also requires "1 passed" in the child's output, as
layout_cache_follows_fonts_added_later in crates/tools does.
Main replaced the glob import of the command helpers in fileio/eps.rs
with an explicit list; the EPS Save path's selectedOnly check uses
bool_or, so it is added to that list.
File > Document Color Mode and document.open {colorMode} converted the
colors of the layers, symbols, pattern tiles and swatches only. Graph
designs, graphic styles, the art of opacity masks, the tile that
pattern editing's Cancel puts back and the art of brushes kept their
old color model (only a tint of a global swatch in a graphic style or
a mask followed the swatch), so a CMYK document could still apply,
place or print RGB colors from them.
These now convert with the rest, in the same undo step: their solid
colors, gradient stops, text runs and mesh points, nested masks
included. A Hue Shift brush's key color takes the converted color of
the art color it matches, a tint of a global swatch included. The
brush library is stored again only when one of its colors changed. A
tint of a global swatch in any of these places becomes the converted
swatch's color at its tint, as in the layers. The reply's changed
count covers the colors of the layers, symbols, graph designs, pattern
tiles and opacity masks; the colors of graphic styles and brushes
convert without being counted.

While an opacity mask or a pattern was edited, a Shaper scribble and
Object › Shaper › Release and Expand ended isolation, and a Shaper
double-click on a Shaper Group isolated the group's original shapes.
Each replaced the editing layer's isolation while the document stayed
in mask or pattern editing. A click on the Shaper Group's mode widget
did the same through object.isolate.
A scribble, Release and Expand now keep the editing layer isolated in
these modes, and end isolation as before outside them. A double-click
with Shaper selects the original shape under the pointer without
isolating the group's original shapes, and the mode widget does not
show while a mask or a pattern is edited.
Docs: docs/shaper.md, docs/target-app-parity.md.
Pattern Brush Options has a menu below the Outer Corner Tile and the Inner
Corner Tile. Each can be the brush's own corner art (Original), None, or one
of four tiles made from the side tile at each corner of the path:
- Auto-Centered stretches one side tile around the corner, centered on it.
- Auto-Between bends a side tile on each side into the corner, the two
meeting on the corner's diagonal.
- Auto-Sliced lays a side tile on each side past the corner and masks it
at the diagonal, so the two meet like a mitered frame.
- Auto-Overlap lays a side tile on each side past the corner, overlapping.
The tiles are straight at the corner and follow the path towards the side
tiles, so they meet a curve that runs into the corner. A side tile taller
than the corner can reach is stretched along until the two sides meet. On a
short path, a corner's tile is squeezed along so that it covers at most the
path up to an open path's end and half way to the next corner, and its two sides still meet on the
corner's diagonal.
The definition stores the choice as `outer_source` and `inner_source`
(`none`, `autoCentered`, `autoBetween`, `autoSliced`, `autoOverlap`), which
`brush.options` sets. Corner art wins over a source. A brush saved without
a source draws as before: a kind of corner without art takes the other
kind's art. None leaves that kind of corner empty.

Enter Isolation Mode worked while an opacity mask was edited, and Edit
Opacity Mask and View Opacity Mask worked in isolation mode, so each
mode replaced the other's isolated art. In the reference app, isolation
mode can't be entered while a mask is edited, and mask editing can't be
entered in isolation mode.
object.isolate and perspective.editText, which shows type in isolation
mode, are now off while an opacity mask is edited, and a call returns
an error that ends "stop editing the opacity mask first". In isolation
mode transparency.editOpacityMask and transparency.viewOpacityMask are
off, and transparency.makeOpacityMask refuses one target, an object or
a layer, which it would take into mask editing; a call returns an error
that ends "exit isolation mode first". Make Opacity Mask with two
objects still masks one with the other. Pattern editing mode does not
count as isolation mode for these commands.
Object > Perspective > Edit Text, the canvas context menu and the
Transparency panel's menu and Make Mask button follow the commands'
enablement. A click or Alt-click on the mask thumbnail in isolation
mode shows the error and does not edit the mask. While a mask is
edited, the Contextual Task Bar leaves out Isolate, and the Properties
panel's Quick Actions leave out Isolate Group.
Docs: docs/mcp.md, docs/target-app-parity.md.
The reference app disables its Lock, Hide and Show All menus in
isolation mode. In VectorCraft every item of Object › Lock and
Object › Hide, Unlock All and Show All worked there.
In isolation mode, object.lock, object.lock.above,
object.lock.otherLayers, object.hide, object.hide.above,
object.hide.otherLayers, object.unlockAll and object.showAll are now
off. Their menu items are greyed out, and a call returns an error
that ends "exit isolation mode first". The Contextual Task Bar's
Lock button is greyed out too, and the Properties panel's Quick
Actions leave out Lock. Pattern editing mode and opacity mask editing do not count as
isolation mode for these commands. The check is outside_isolation in
cmd.rs, with has_selection_outside_isolation beside it.
Docs: docs/mcp.md, docs/target-app-parity.md.
A Blob Brush stroke used to merge with every closed path of its fill
color and no stroke that it touched, anywhere in the document, across
layers and groups and past objects of other kinds. It now merges with
the topmost such path it touches, and with the other touched matching
paths in the same group or layer that are next to that path in
stacking order, with no other kind of object between them. Merge only
with selection still limits the candidates to selected paths. The
merged path keeps the topmost path's id and place.
The reference app places a new layer below the selected layer with
Ctrl+Alt-click (Command+Option-click) on the New Layer button, and a
new sublayer at the bottom of the layer list with the same click on
the New Sublayer button. In VectorCraft that click opened Layer
Options, and New Layer and New Sublayer always added the layer above
the current layer and the sublayer on top of the layer's contents.
layer.new takes below, which adds the layer directly below the current
layer at its level, and layer.newSublayer takes bottom, which adds the
sublayer under the parent's contents. In a clipping layer the new
sublayer goes above the clipping path. Each is one undo step, and
below is refused together with top. A Cmd/Ctrl+Alt-click on the
Layers panel's New Layer and New Sublayer buttons runs them. A plain
click, an Alt-click and a Cmd/Ctrl-click work as before.
Docs: docs/mcp.md, docs/target-app-parity.md.
A .ai file whose editing data has no layers, as swatch libraries are
saved, opens from its PDF part, and the PDF part has the default
swatches. layered_ai applied the editing data's palette only when it
built the document from the layers, so Other Library… listed the
default swatches for such a library, and File › Open gave the file the
default swatches as well. A .ai whose layers can't be used (an image
too large for the editing data's reader, or a read error) lost its
palette the same way, and so did an EPS that opens as its page.
The reader now reads the palette on its own (ai::palette, which shares
palette_swatches with the layer reader), and its swatches and color
groups replace the default swatches in those three cases. Spot and
pattern swatches of the PDF part's art that the palette does not have
follow the palette's swatches.
Fixes#4100. Part of #3349.
The Type tool heard of Undo and Redo only when they ran as top-level
commands. As steps of command.batch, they left the caret where it was,
and the tool took the batch for an outside edit. Session::execute now
tells the active tool about each nested edit.undo and edit.redo.
command.batch also tells the tool when it begins, ends or rolls back.
The Type tool keeps its caret and its edit records at the start of each
batch and puts them back when a failed batch rolls the documents back.
GIF, WebP and Targa files hold no resolution field, so document.formats and
the export docs now say that ppi, and the resolution that width or height
gives, are stored in the file except in those three formats.
PNG, PNG-8, JPEG, WebP, GIF, TIFF, BMP, Targa and PSD exports take
`width` or `height` in pixels. Each file is scaled so that its own
artboard, `rect` or art bounds is that wide or high, so with
`useArtboards` every file gets its own scale. `width` wins over
`height`, and either wins over `ppi` and `scale`, in the order an
Export for Screens row reads its size. The scale stays within 0.01 to
64 pixels per point and the file stores the resolution that results.
A value that is not a positive number is refused.
The per-file scale comes from `ScreenSize::scale_for`, which Export for
Screens rows already use. Rows keep their own size: their format
settings still drop `width` and `height`. `document.formats` lists the
two options for every raster format.
