Create Gradient Mesh's To Center / To Edge highlight lightened every point
towards RGB white, so a CMYK (or grey) point became display RGB. A patch with
any non-CMYK corner then mixes in RGB, and the PDF writer separated those
colours back to CMYK with K = 0, moving ink off the K plate. Points now
lighten towards white in their own colour model (no ink for CMYK), so the
mesh stays CMYK and K shrinks with the other inks. Flat meshes (highlight 0)
already kept their inks.
An 8-bit PCX file whose image data is followed by the palette marker
(0x0C) and fewer than 768 color bytes was read as gray levels. The reader
now notes where the run-length encoded image data ends, and when the
palette marker follows it without all 768 colors, refuses the file as cut
short. An 8-bit file with nothing after its image data still reads as
gray levels, and a gray level of 12 that falls 769 bytes before the end of
such a file is read as a pixel instead of as the palette marker.
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.

Pages that share one Contents array made the name of a refused stream read that array once per page, quadratic in a crafted file. Each object is now read once, and a page's own array as before. From the review of #4612.
A page's Contents can be an array written as an object of its own (/Contents 6 0 R). Its streams were named "a stream in it": the reference was compared with the stream, not the array's items. From the review of #4603.
The Quick Actions listed Object › Path's Offset Path and Simplify for every
selection, but both take paths: with type selected, the dialog opened and
could only fail ("Offset Path: select paths"). They are now left out when
every selected object is type, as Lock and Isolate Group are when they can't
run; live type offsets through the Appearance panel's Effect › Path ›
Offset Path, which works on type.
Follow-up to #4345 / #4145 per maintainer guidance from @bflatastic.
- In `crates/effects/src/geometry.rs` & `crates/effects/src/reshape.rs`:
- Implements `optimize_geometry_effects`: reorders pure-translation Transform effects
with copies after a terminal round-join Offset Path effect when the effective style is safe
(NonZero fill and no stroke).
- Offsetting a union equals the union of offsets for round (Minkowski) offsets; moving
pure-translation copies after the terminal offset evaluates Offset Path once on the base
geometry rather than over dozens of multiplied copies, turning O(copies * segments) planar
sweep explosion into a single fast offset plus lightweight affine copies.
- Safely commutes across multiple consecutive pure-translation Transform effects.
- Preserves exact visual geometry by leaving miter, bevel, EvenOdd, stroked, or non-terminal
effect stacks in their original order.
- Added comprehensive unit and regression tests in `crates/effects/src/tests.rs`.
- Added contributor entry in `contributors/people.toml`.
Follow-up to #4600, from its review. A start left OpenGL out whenever
Direct3D 12 listed an adapter, and WARP, its software adapter, is
always listed. So a GPU without a Direct3D 12 driver, which drew
through OpenGL before, now drew on the CPU. An adapter that
WGPU_ADAPTER_NAME named was left out too when it was an OpenGL one.
OpenGL is now listed when Direct3D 12 lists no hardware adapter and
when WGPU_ADAPTER_NAME is set. The Direct3D 12 check takes the shader
compiler the window does (WGPU_DX12_COMPILER, else FXC).
Pattern, art and auto-corner brushes used to flatten the art into chords
wherever the path bends, so Expand Brush Strokes left polygons with
hundreds of corner anchors. Each art segment now comes out as cubics
matched to the bent segment's ends and derivatives and halved until they
hold to a quarter of the flattening tolerance (never below the 0.05 pt
the path is flattened to). Anchors stay anchors, lines that stay straight
stay lines, and the halving is capped in depth and in anchors: where the
fit would take more anchors than the chords, or the map gives points that
are not finite, that subpath falls back to the chords, now without the
non-finite points.
A 4-anchor circle tile round a 400 pt circle: 68 anchors a tile -> about 9,
all with handles, 0.04 pt from the bent art against 0.19 for the chords;
stroke_pieces 169 -> 244 us for the 31-tile stroke.
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).
With Styling set to Internal CSS, Inline Style or Style Entities, font-size
and letter-spacing were written as bare numbers. Only presentation attributes
take a bare number; in CSS a browser drops them, so the type was drawn at its
default size. They are now written in px, SVG's user unit, and presentation
attributes keep bare numbers.
wgpu's OpenGL backend on Windows keeps a hidden window on a helper
thread that pumps no messages (gfx-rs/wgpu#10504). Windows hands an
input-language change to every UI thread of the process and waits for
each, so switching the keyboard to another layout hung the whole app,
even while it drew with Direct3D 12. OpenGL was started on every
Windows start, as the fallback.
A Windows start now lists Direct3D 12 alone. OpenGL is still listed
where it is the fallback: after a start crashed on an adapter or while
listing them (#2243), after a restart that left an adapter out, and when
Direct3D 12 lists no adapter at all (Windows 7). WGPU_BACKEND still
picks the backends as before.
A page drawing one form over and over made its art again for every drawing
with no limit (a 1 KB file took 877 MB), and a form decoding to 64 MiB drawn
a thousand times hung. The import now makes at most half the objects a saved
document may hold (2M, 256K on the web), leaving the rest out with a warning,
and the scan reads at most 2 GiB of form content per page before refusing it
as past the reader's limits.
