An image or a gradient mesh with a visible Crop Marks effect, or with a
Vector Halftone effect that makes dots, is measured in a plot of the art's
bounds. A halftone that makes no dots, such as one past the effect's cell
limit, leaves the image out as before.
The bounds of a plot of the art's bounds no longer count the objects a
plot leaves out (placed images, objects at 0% opacity, unpainted paths)
when they sit in the art of a symbol. An instance whose symbol holds
nothing else is left out, so a document with only such instances is
refused with "nothing to export". The art of a dynamic symbol, and of a
group with effects, fills or strokes of its own, is measured whole.
With useArtboards off, PDF, .ai and HP-GL exports sized their one page
by every visible object, including art they then leave out. A PDF
without includeNonPrinting or createLayers drops non-printing layers, so
art on such a layer made the page larger than what was drawn, and a
document whose only visible art did not print came out as a blank page.
An HP-GL plot draws nothing of non-printing layers, objects at 0%
opacity, placed images, gradient meshes whose every point is at 0%
opacity and paths that paint nothing, and such art moved the plot's
origin.
The page is now measured with that art hidden, and a document with no
other visible art is refused. A .ai file is measured with the PDF
options it is written with, so it keeps non-printing layers unless both
createLayers and includeNonPrinting are off. The PDF writer's own
non-printing filter uses the same helper, and the HP-GL writer's
plots_nothing says which objects a plot draws nothing of. Export As
measures an HP-GL plot of the art's bounds the same way, so a document
with nothing the plot draws stays in the dialog before the save panel.
A trace handed in for imageTrace.make or imageTrace.makeAndExpand was
matched by its object, image, pixels and settings alone, so a trace made
in one document could stand in for the command in another open document
with the same image and settings. The trace's inputs now carry the
document's uid: TraceRun::current is false in any other document, and the
commands there drop the trace handed in and trace their own image, as one
undo step.
Test: a_trace_run_applies_only_in_its_own_document.
Document::symbol_art_bounds measured a symbol's art without the
document, so an instance of another symbol in that art counted as the
20 x 20 square. It now measures the art through SymbolBoxes, so a nested
instance takes its own symbol's art, and an inline graphic of the outer
symbol is sized by it and follows it when that symbol changes.
- The inline resolve order also follows the instances that size a
symbol's art, so a symbol is measured after the type in the art of
the symbols it holds is laid out again.
- A symbol whose art reaches itself through an instance and an inline
graphic is an empty slot. Only instances that the measurement uses
count, so one a clipping path hides adds no dependency.
- A missing symbol, a symbol without art, a symbol that holds an
instance of itself, and nesting 32 deep still measure as the square.
- SymbolBoxes finds symbols through a name index built once, and the
inline resolve pass and inline_art_bounds share one index, instead
of scanning the symbol list for each lookup.
swatch.spotOptions and swatch.resetDefaults {replace: true} rewrite the
fill and stroke for new art through map_default_paints, which also runs
for command.batch steps. Two tests now run each command on its own and
as a batch step followed by a rectangle, and check that the default
paints and the rectangles match: a Lab spot link keeps its tint and
takes the Lab values or their CMYK equivalent in both directions, and a
link to a swatch the replace removes is dropped while the color stays.
Both tests fail when map_default_paints skips every interaction.
The progress line for swatch steps in a batch names the two commands and
the new tests.
A gradient stop linked to a spot ink that also carries process plates
(a DeviceN stop opened from a PDF) printed only its spot tint: print
separations and Separations Preview left its Cyan, Magenta, Yellow and
Black plates blank. They now print the stop's plates beside the tint.
With spots printed as process, each process plate prints the stop's
plate layered with the spot tint's process equivalent, as a separated
image's spot plates layer. Plates beside no spot link, or beside
Registration, still print nothing of their own.
The color visitor also skipped a freeform gradient's points, so print
plates kept their display colors and Document Color Mode left them
unconverted. The points are now visited as unlinked colors.
swatch.edit stored a replacement gradient without its placement, so a
radial gradient with an aspect, Alt-dropped on a gradient swatch or
given as `paint`, lost that aspect, while swatch.new keeps it and
applies the swatch with it. A gradient given an aspect without `start`
and `end` lost the aspect in both commands. A replacement pattern kept
the tile transform of the swatch it came from, while swatch.new stores
a pattern untransformed, and `paint: {pattern: name}`, which an Alt-drop
of a pattern fill sends, was refused.
swatch.edit and swatch.new now store a gradient or pattern through one
helper: a gradient keeps its aspect, with or without a vector, and holds
no swatch link, and a pattern is untransformed. swatch.edit takes a
pattern by name, as swatch.new does.
