Edit Colors > Convert to Grayscale wrote the new image as an RGBA PNG, so
a PDF wrote it as DeviceRGB, in a CMYK document too. The image is now
stored as a gray PNG, with alpha only when some pixel is not opaque. Adjust
Colors with mode gray and convert does the same.
An RGB image whose pixels are already neutral now converts, and an image
already stored as gray with no visible change is left as it is.
A new test changes the document in place (Arc::make_mut, with no other
holder and no change of revision) and checks the answer is measured
again: keyed on the document's address alone, it would keep the old
answer. The kept answer's doc says what it holds after the measure,
and that the fonts set the bounds of all type. Should measuring ever
ask again while it runs, it is measured without being kept, rather
than borrowed twice.
The stack overflow fixed in d5d04f868 also hit EPS export, and the
parity rows now say so. Two test docs are corrected: the fill-only
clipping is an older bug on main, and the outline-view difference runs
both ways on a few dozen hairline pixels.
The engine reads null params as {}, but engine.commands listed every
schema with the root type "object", so a client that validated a call
against the schema refused one the engine accepts. A schema with no
required parameter now has the root type ["object", "null"]. A schema
with a required parameter keeps "object", because the engine refuses
null params for it as a missing parameter. Nested objects are unchanged.
Check a new call's params against the schema in execute_spec, after the
key check and before the parser, and check every command.batch step
before the first one runs. menucmds::run_raw and the two other direct
runs go through the same check. Saved steps keep keys the schema does
not name and have the values it names checked.
Limit nesting to 16 levels, cut error text and paths to a fixed length,
and copy nothing before it has passed. Treat a whole number written
with a fraction as an integer. Check declared defaults and duplicate
names once at first use.
Give the five schema errors rows in the 22 complete-message catalogs.
- The parity rows say what the fix covers: a 3D effect on a fill or
stroke that builds nothing overflowed the stack with no effect of the
object's own too, on the canvas, in Object › Rasterize and in raster
exports.
- The builds-nothing test says the fill-only difference (a raster
effect clipped to the path, cutting Roughen's spikes, when drawn
without the 3D effect) is an older bug, not the design.
- The traced-shape test says why its area is bounded rather than drawn
again: a partial render in outline view differs from the whole by one
in alpha on 37 pixels, older than the test and unrelated to the edit.
- A doc comment rewrapped.
Flatten Transparency composited each region over white, so a blend mode
on the bare page read that white. Raster renders now draw their
background under the finished art, and the flattened color no longer
matched them: a Color Burn object on the bare page flattened to white
and rendered in its own color. The region now composites the art alone
and puts the white under it.
- Tests that relied on the white under the art now draw art under the
style (`every_builtin_style_paints_visibly_on_a_rectangle`) or compare
only whole-pixel pans with a fresh render
(`a_coarser_glow_kept_whole_draws_after_a_pan_as_made_again`).
- New tests cover every blend mode on white and blue backgrounds, a
thumbnail and the ink planes with a Screen glow, and
`over_background` at background and pixel alpha 0, 128 and 255.
With Scroll Sideways with Cmd/Ctrl + Wheel on, wheel() turned all
Cmd/Ctrl wheel motion into a sideways scroll unless it arrived as a
pinch event. A wheel turn now zooms about the pointer once it holds an
event from a trackpad source, point deltas from an unnamed source in the
desktop app, or line deltas that are not whole notches. Whole notches
keep scrolling sideways, and the option's default is unchanged. The same
rule applies with Zoom with Mouse Wheel on. egui-winit reports a wheel
source only on macOS, so the delta decides elsewhere.
Docs: docs/mcp.md, docs/target-app-parity.md.
- A 3D effect that builds nothing: af754bcb2 said the object draws exactly
as without it under a Drop Shadow or Gaussian Blur. That holds only for
a stroked object. With only a fill, the raster effect draws from the
art made for the object, where without the 3D effect it is clipped to
the path, so Roughen's spikes differ: the earlier wording was right.
The test keeps the stroked cases exact and restores fill-only cases
with a Drop Shadow and a Gaussian Blur, which differ in under 4% of
the pixels and nowhere inside the path. Its reach check compares with
the object drawn without its raster effect, since Roughen alone
reaches past the path.
- The Vector Halftone test's bounds are a consistency check, and only
holding no art tests the branch: its doc no longer says no solid is
built (the free measure's halftone arm builds one). The overprint
test's area check is labeled likewise.
- Recoloring a traced shape bounds the area the renderer that drew the
trace object measures too, inflated by half the stroke and a pixel.
- The let-go test pins the nothing-to-draw branch: no frame, whole or
part, began since the measure.
- The parity doc's feature row names the stack overflow fix and its
test; a group test's doc says what its fixture holds.
A raster export filled its background into the page before the art, so
blend modes read it as art underneath: an Outer Glow in Screen mode, the
default, turned white on a white background and was missing from PNG and
JPEG files while the canvas showed it. Blending against nothing also
differed from the canvas for Difference and the other modes.
The background now goes under the finished art, in frames and in object
thumbnails. A blend mode reads only the art below it. A white object
under a Difference object still inverts.
Page Isolated Blending no longer changes a raster export on a bare page.

An image in a Separation color space opened as an RGB image: its spot ink
was lost (no plate in Separations Preview), and Fill and Recolor Artwork
didn't reach its color.
It now opens as a grayscale image of its tints (white where it lays no
ink, black at 100 %, its Decode array applied; 1 to 16 bits a sample, or
one gray channel from its JPEG, CCITT, JBIG2 or JPEG 2000 decoder),
colorized by its ink at 100 %: the spot swatch, a process plate's CMYK
color, or Registration. Its mask becomes its opacity mask, as a CMYK
image's does. The ink is found by the image's color space among those the
file defines, once per image. The ink None, an ink whose color can't be
told, images inside an alpha soft mask, inline images and DeviceN images
open as before; samples that can't be read open in RGB with a warning, and
the ink gets no swatch.

A mark glyph's vertical translation started a new draw_glyphs batch, so
krilla received the cluster's source range again and mapped its
characters twice. Copying or searching the exported PDF then found
doubled letters for Arabic harakat in any font, and for every dotted
letter in fonts that draw dots as zero-advance mark glyphs (Noto Sans,
Naskh and Kufi Arabic).
Keep compatible glyphs on the same layout line in one batch and carry
their relative vertical placement as per-glyph y_offset; horizontal
placement is unchanged (next_x - x advances). Font, size, linear
transform, line/column, paint run, list marker and hyphen boundaries
still split batches. Krilla keeps owning cluster mappings and
ActualText. No importer change.
Regressions decode the content stream and ToUnicode maps: one batch per
layout line, no duplicated cluster assignment, one ActualText per
multi-glyph cluster, contours within 0.05 pt of outline export; mixed
scripts, vertical columns, path rotations and PDF/X variants covered.
The reader round-trip stays an ignored test until the importer consumes
ActualText (#6165).
Addresses #6309.
Editable PDF import derived characters from glyph Unicode/CID mappings
even when the enclosing marked-content sequence supplied /ActualText.
A span that paints "xy" but says "AB", followed by "C", imported "xyC".
Track the outermost replacement owner per span (absent, explicitly
empty, consumed), decode it with the existing PDF text-string decoder,
emit it once at the first placeable glyph, and let the remaining glyphs
of the span advance the pen without phantom character slots or
inferred spaces. Authored stretches keep their logical order while
adjacent ordinary text still goes through visual-to-logical
reconstruction. Glyph identity still drives font matching. Depth and
size are bounded; oversized or unbalanced spans fall back to glyph
mappings with a warning.
Outlines mode and PDF export are unchanged. Parity docs updated,
scores unchanged.
Fixes#6165.
A PDF image mask (`/ImageMask true`) painted in a solid color opened as an
RGB image with the color in its pixels: Fill and Recolor Artwork didn't
reach the color, a spot color lost its ink, and the same mask painted again
in another color took the first one, because the painted image was cached
by the mask alone, and so did an uncolored pattern whose cell draws a mask.
It now opens as a grayscale image of what it paints, colorized by that
color, as the .ai reader opens a 1-bit image mask (#5790). A spot color
keeps its swatch and tint. The page's walk counts paths, not images, so the
ink is found from the color space. Readings of a pattern cell are told
apart by colorized images' colors too. Inside an alpha soft mask, or
painted with a pattern, a mask opens as before.

copyFrom only writes paints enabled for pickup and apply, and paint, Transparency and the Eyedropper record an undo step only when the override changes.
copyFrom still edits the part when reverse, append and defaultsOnly are false, and reverse copies onto source. transparency.set records an undo step only when the override changes.
A picked part takes transparency and the Eyedropper only when those calls omit their other targets. Art, Pattern and Bristle brushes, native Wayland and the web still do not take tilt, bearing or rotation.
