Mesh export tested the middle of every segment against every closed contour's bounds, so a profile of thousands of separate contours took hundreds of millions of comparisons before the work limit counted any. The closed contours now go in a grid over their bounds, a point is tested only against the contours of its cell, and placing a contour in a cell and each candidate looked at count toward the limit.
A member of a group with Revolve drew its surface in Normal mode whatever its own blending mode or that of a group it is in. Each mode now applies once, to the member's surface or to the surfaces of the group that has it, nested as the groups are. Expand Appearance keeps every face of a blended member.
Revolve, Extrude & Bevel, Inflate and Rotate on a group or layer draw only as the group's own effect. On the group's fill or stroke they drew nothing, yet effect.apply and effect.setParams accepted them. Both now refuse that placement.
Each fill or stroke with its own Revolve counted the copies of its paint from zero, so an object with several of them could draw past the 256 MiB budget. They now share one count, and past it the source path draws, as for the members of a group.
effect.apply and effect.setParams on a fill or stroke now check the Revolve in that item's paint, after the item's geometry effects before it, together with the object's other items that carry a Revolve. Before, they checked the object's top fill.
docs/revolve.md marks the axis position, type handling and member paint as VectorCraft's own rules, and docs/mcp.md says how the budget is counted.
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.
Type sweeps as its glyph outlines and stays editable. On a group or layer every visible member sweeps about one axis on the edge of the members' bounds together, each in its own paint.
A surface now takes up to 16,384 profile points and 163,840 faces. Curves take fewer samples, down to 4, when a surface passes those limits, and the command reports the failure below that, after the geometry effects before the Revolve and with the cumulative size of its paint copies counted. Mesh export turns the walls of holes toward them. Expand Appearance works on type with Extrude as well as Revolve.
Fixes#3617
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.
The grid is view state of each open document, with no undo step, so its schema's x-writes is session rather than the default document. A test pins x-writes for all six View commands, and the level 1 schema hash is updated.
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.
The answer whether Fit to Artwork Bounds has art to fit moves from a
function-local thread_local to DocState, beside any_empty_artboards, and
drops with the document. It is kept for that version of the document
(held weakly, as any_empty_artboards holds its own) and the artboards
asked about, and measured again when the installed plug-ins, whose
effects draw art, or the installed fonts, which set type drawn by its
effects' art, change: their generations are an explicit input of the
measure. A change of the selection or the view keeps it.
The test counts the measures, as the Delete Empty Artboards check's
does: a later frame, select.set and a view change keep the answer; an
edit, other artboards, and each generation measure again. Taking any
part out of the key fails it.
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.
fit_has_art kept its answer for the document's uid and revision, which
don't follow every change of what it measures: a document's tab coming
to the front replaces it with its composite fonts synced, and a plug-in
installed or removed changes what its effects draw, with no revision
moving either time. The answer is now kept for that document Arc, held
weakly as DocState::any_empty_artboards keeps its own, and the artboards
asked about, until the plug-ins' revision moves. A selection or view
change keeps it.
The test replaces the document with art on an artboard, its revision as
it was, and asks again: kept by revision, the answer was stale.
- 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.

Review follow-ups:
- The test that art measured for an edit not drawn on this thread is let
go first checks that measuring the edit through the canvas's renderer
holds art, so a measure that held nothing can't pass it. Its worker is
a test channel whose job the test receives, in place of a real thread's
pending job, which a finished frame could clear. Taking out either
let_go_of_measured fails it.
- fit_has_art's comment says why its one kept answer can't be stale: a
document's uid is never reused in the process and its revision only
moves forward.
Review follow-ups:
- The tests that a group with effects of its own is measured once a pass
plant its kept bounds after the first artboard and read them back over
the next two, so a measure made again fails. Its solid is built by the
free measure, which the renderer's three_d_built doesn't count.
- The budget test checks that every object, past the budget too, is
measured as the free measure does and draws as a new renderer draws it.
- A 3D effect that builds nothing draws the object exactly as without it,
with a Drop Shadow or Gaussian Blur too, which reach past the path. The
doc comment said those differ past the path; they don't.
- The brush widened in view first checks that the wider brush draws
otherwise.
- Recoloring a traced shape changes no more than the shape, its stroke
and a pixel's anti-aliasing.
Review follow-up: these three branches of what a renderer measures had no
test. Under Overprint Preview a renderer measures an edit as changed()
does and holds none of the 3D art it made for it; a 3D effect with
Vector Halftone is measured by the free measure, with no solid built and
no art held; and on screen in symbol editing mode, an edit to the
instance it was entered from changes nothing. Each test fails with its
branch taken out.
The 3D effects refuse objects they can't build from, such as clipping
groups and blends under Extrude & Bevel. The preview failed, OK stayed
on and only repeated the error in a status-bar line that gets cut off,
so the dialog looked broken.
The dialog now shows the command's reason under Preview and turns OK
and Enter off while it holds. With Preview off, it tries the values
once when they change and rolls back, so the reason still appears.
Three geometry fixtures used unembedded Helvetica, so the reader fell
back to Source Sans 3 widths where Helvetica is not installed (CI) and
fitted the line length instead of placing glyphs exactly; the following
"C" then landed about 3 pt off its untagged comparison. Embed the
bundled Source Sans 3 with matching explicit widths. Every assertion and
the 0.05 pt tolerance are unchanged.
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.
