The DestIn mask now covers the whole render target (and the PDF's
exported area), with the gradient kept in item space through the paint
transform, since past the gradient's ends the end opacity carries on: a
child's long drop shadow or thick stroke is faded, not cut off at a box.
feather_bounds counts only shown children and active states, walking
nested groups without recursion.

A gradient feather on a group (Gradient Feather tool over grouped text, as
in LYH Studio's poster tutorial) did nothing on screen: groups never went
through the effects path. In PDF the group's mask was the group's own path
bounds, and a group has no path, so the mask covered a box of zero size and
hid the group.
- Item::feather_bounds: the box the feather spans, the objects' bounds for
a group.
- Render: a feathered group draws its objects in one layer, then fades it
with the same mask as other objects (fx::gradient_feather_mask).
- PDF: the group's mask spans its objects.

Conflict: ROADMAP.md: both progress lines
Conflict: docs/gaps.md: next's header, clipping paths added to its change list
Conflict: docs/target-app-parity.md: next's header, clipping paths added to its change list
Conflict: crates/doc/src/item.rs: both Graphic methods (next's shown_bounds, the branch's clip_region)
Conflict: crates/idml/src/names.rs: both imports (ClippingKind, ContourType)
Conflict: crates/idml/src/export.rs: both pushes, TextWrapPreference first, then the clipping settings
Conflict: crates/idml/src/import.rs: both lets (next's wrap, the branch's clip)
Conflict: crates/engine/src/cmd/file.rs: next's size and transform, plus clip: None
Conflict: crates/engine/src/cmd/datamerge/fill.rs: next's Graphic with wrap, plus clip: None
Conflict: crates/engine/src/cmd/mathexpr.rs: next's Graphic with wrap, plus clip: None
Conflict: crates/pdf/src/tests.rs: both tests
A placed graphic keeps its clipping path (Detect Edges, Alpha Channel,
Photoshop Path or User-Modified Path) in graphic space, with the
options IDML carries. IDML import reads ClippingPathSettings and its
saved ClippingPathGeometry (anchors capped, non-finite subpaths
dropped); export writes them back. The canvas and PDF export clip the
image to the path inside the frame clip; an inverted path shows the
image outside it. Without saved geometry nothing changes.
object.clippingPathOptions reports a graphic's clipping path, inverts
it or removes it (Object > Clipping Path > None).
Fixes#450.
Parent-page text now uses the absolute page index as its cache key, so repeated page numbers and renumbering do not reuse another page's composition.
Validation: targeted canvas and PDF regressions, plus all six cargo xtask ci gates on main after #514 (1,179 native tests passed, 3 ignored; 15 crates passed WASM compilation checks).
Task: #523
A running header (or any text variable) in a parent-page frame was empty or
wrong on pages whose page number repeats an earlier one: with two sections
that both number from 1 (front matter 1-10, body 1-...), body pages 1-10
showed nothing. The renderer and PDF export passed only the page's name to
the composition cache, which looked the page up as the first page with
that name - in the front matter, before any heading.
CompositionCache::get now takes the absolute page index (None for a story's
own frames) and derives the name for page-number markers from it; the cache
is keyed by index, so two pages with the same name no longer share a
composed header. The renderer and PDF export pass first_page_of_spread + i.
Test: running_header_on_parent_page_with_repeated_page_numbers (pages named
1, 2, 1, 2; the only heading on the third page). Before the fix the third
page's header was empty (0 glyphs); with it, "Epsilon" (7).
Found with an InDesign IDML (a dictionary with two sections and Match
Character Style running headers on its parent page), together with #301.

8806a223 (next, for #392) drew a slanted glyph with run while a
right-to-left line span was open, so its tagged span would not nest in
the line span. pdf-rtl-text (8f30ba1c) removes the line span and its
line_span flag, so the glyph always goes through tagged_run. The
regression test keeps its export of tagged and untagged PDFs with shatai
Hebrew and checks what the branch's tests check: reading-order text,
no marked content opened inside an ActualText span, and no ActualText
wider than a word.
poppler positions an ActualText with the transform in force where its
span ends; a line span closes outside the runs' transforms, so pdftotext
placed the line text off the page and dropped it. An ActualText per run
fares no better: poppler reverses its characters in a right-to-left
line. Without them, poppler orders the glyphs of right-to-left lines
itself and extracts whole lines in reading order, and the content stream
keeps listing them in reading order. With no line span left, glyphs in
it no longer need to avoid krilla's cluster spans, so that workaround
goes too. The tests that read the line span's ActualText now check that
ActualText never spans more than a cluster.
krilla wraps a mark cluster that maps to several glyphs, and a glyph drawn
with other text than its font already maps it to, in an ActualText span.
Inside a line's ActualText span that nested the spans, and poppler drops
the text before a nested span. Inside a line span each glyph now gets the
text its font maps it to (the exporter keeps a copy of krilla's mappings),
a cluster's text goes to its first glyph, and a run splits into separate
draw calls where two glyphs in a row would share an empty range. A run
drawn through tagged_run inside a line span takes the span as its tag.
Test: mark_clusters_in_right_to_left_lines_open_no_span_of_their_own
(5 nested spans before).
Conflicts:
- crates/pdf/src/text.rs run_text: the branch's two generated_text
branches first, then #392's kashida branch (no text), then the cmap
fallback for other inserted glyphs.
- crates/compose/src/lib.rs: next's kashida PlacedGlyph (with dx) gets
generated_text: None.
- crates/compose/src/shape.rs hyphen_after: next's rendered_char/moji
resets and generated_text = None.
- crates/compose/src/ruby.rs: next's ruby module (#363); the branch's
edit to the old ruby set() has nothing to apply to.
- crates/pdf/src/tests.rs: tests from both.
Also, so the merge compiles: next's ruby (ruby.rs annotate) and kenten
(kenten.rs shape_mark) PlacedGlyph literals take generated_text: None;
they map back through the font like other inserted glyphs. Kanji page
numbers, composite-font note numbers and fallback-face label segments
go through shape_segment's replacement and list labels through
prepend_label, so they carry their generated text.
next's shatai path draws a slanted glyph on its own through tagged_run,
which opens a Span; inside #392's right-to-left line span that nested
marked content and krilla panicked ("can't start marked content twice")
in tagged exports. While a line span is open, the glyph is drawn with
run like the line's other runs. Test:
shatai_glyphs_in_right_to_left_lines_stay_in_the_line_span (panicked
before).
Lines with right-to-left text are wrapped in a marked span whose
ActualText is the line's text in reading order, so viewers that order
text by position (Preview, PDFKit) no longer return it reversed.
A base letter and its marks (Hebrew points) map glyph by glyph when
each glyph stands for one of the cluster's characters, and are drawn in
text order, so ToUnicode-only extraction reads each letter once with
its points after it. Marks stay in their run, placed by glyph offsets
(compensated for skew), instead of starting runs of their own.
Kashidas inserted by justification carry no text.
Fixes#392.
Generated glyphs (page numbers, section markers, list labels) carry the
text they were shaped from, so a figure the font substitutes under small
caps or other OpenType features extracts as the digit instead of U+FFFD.
- table.setCell starts each chosen edge from the stroke rendering draws there (the winning
copy of a shared edge, the row/column pattern, or the table border) and writes the result
to both copies; table.getCellStroke reports drawn edges, counting each shared edge once.
compose::table::cell_side_strokes shares the resolution with the renderer.
- Commands accept dash patterns of 1-64 lengths, each 0 or 0.1-10000 pt. Screen and PDF
draw a dash or dot pattern that would repeat more than 20000 times along a path as solid.
- Stripes, wavy, hash and gap colour extend by half the weight at table corners.
- Cell Options: an edge change reseeds every stroke field and tolerates a non-object seed.
- Edge proxy: a triple-click decides from the choice before the first click.
Conflicts: compose lib.rs imports (both; Composer unused), idml tests.rs (both test modules), ui-egui
panels/mod.rs (next's ruler origin with the branch's graphic wrap for Direct Selection).
A right-to-left bound spread lists its right page first, parent spreads
included. The parent page shown behind a document page was picked by list
index (first = left), so every page of an imported right-to-left document
showed the other side's parent items. Pick it by position instead: the
leftmost parent page for a left page, the rightmost for a right page.
New parent spreads in a right-to-left document list their pages right
first, and changing the binding reorders existing parent spreads, so IDML
export writes them in binding order. Spread bleed on the canvas and in
spread PDF export takes the outer edges by position as well.
A placed graphic carries its own text wrap (Graphic.wrap). IDML import
reads TextWrapPreference on the Image/PDF element and export writes it
back there. Layout treats it as an obstacle around the part of the
graphic its frame shows, plus the offsets, and also collects wraps of
items inside groups. object.textWrap acts on the graphic when the
selection is the frame's content, and the Text Wrap panel shows its wrap.
Conflicts: ui-egui dialogs.rs (next's numberingSection arm and the branch's cellOptions arm; the branch's
copies of the dialog test helpers already on next dropped, its cell options test kept); idml tests.rs and
the i18n tables appended at the end on both sides (both kept; the branch's Gap Tint: and Tint: rows that
next already had dropped).
CellStroke and cell/table style edge attributes carry gap colour and gap tint
(IDML ...EdgeStrokeGapColor/GapTint, ...BorderStrokeGapColor/GapTint). The table
renderer and PDF export draw every stroke type on cell edges, with the gap colour
under dashes, dots and stripes.
table.setCell validates stroke values, takes gapColor/gapTint and an edges list
(top/left/bottom/right are the target range's outer sides; innerHorizontal and
innerVertical the lines between its rows and columns). table.getCellStroke reports
the shown values of the chosen edges, null where they differ.

Conflict: crates/idml/src/import.rs: next's char_attrs (tab-split family and composite font names), falling back to names::font_family_in
Borders gain a stroke type (built-in or a document stroke style), cap,
join, gap colour and tint, a shape and size per corner, column or text
width, top and bottom edges, closed boxes in each part of a split
paragraph, and one box for consecutive paragraphs with the same
settings. Shading gains the same corners, edges and width, Clip to
Frame, and Do not Print or Export. Boxes are drawn once the lines are in
place, as filled paths where they aren't plain rectangles.
Span and split paragraphs keep at least their space before and after
from the column text. Lists have levels that number on their own and
restart after a higher level, ^1 to ^9 in the number text, a character
style for the label, a bullet font, left, centre or right alignment at
the line start, and a tab position for the text after the label.
All attributes load from older files with their defaults and
round-trip through IDML, apart from the tab position.
The placed PDF's asset stores its Crop to choice (crop, art, trim, bleed,
media, or the content bounds with visible or all layers) and where that
box sits on the page. The graphic spans the box: the screen, PDF export,
rasterised exports and clipping-path tracing draw only that part of the
page, so a larger frame doesn't reveal the bleed.
IDML export writes the choice as PDFCrop, with GraphicBounds spanning the
box. Import reads PDFCrop back; the engine finds the box on the PDF page
after import (and after relink or update) and maps it onto GraphicBounds,
or gives a graphic without bounds the box's size. Documents saved without
a choice load with the crop box. The Place PDF dialog offers the content
bounds too, and links.list reports the choice.
Export writes a PDFAttribute with the page number and PDFCrop="CropPDF":
the graphic bounds already span the page's crop box, so the frame clips
to the chosen trim, bleed or media box as before. Import reads the page
number back instead of always showing page 1.
A placed PDF page that the PDF does not have (a hostile PageNumber, or
any document holding one) is left out of PDF export with a warning
instead of failing the whole export.
Upstream main moved 9e4f694 -> 736acff by 10 squashes: #258, #285, #153, #280, #288, #281,

menus.rs. contributors/people.toml takes main's (next had a duplicated
[people.emanuelebonaventura] table from the 9e4f694 merge, which broke the ui-egui build

baseline (rule_baseline in render and pdf text_rules); #176 CMYK fallback through
lossless(.., mode) and its updated contract tests; #258 test fixes; #153 and #297 as landed.
A linked image that wasn't found on open has no data; the export warning said it could not be decoded. It now says it is missing and names the link.

* Set warichu as smaller lines inside the parent line.
Type › Warichu stacks the selected run after the line is broken, closes up the rest of the line, and round-trips the IDML warichu properties. The line break itself still sees the full-size run.
* Keep clicks, the caret, and Up/Down on each warichu row.
The glyphs were already stacked inside the parent line, but hit testing, the caret, and vertical movement still used that parent line. Break minimums, row widths, spacing, and tab leaders now follow the small lines, and underlines sit on the small baseline.

* Text frames: column rules draw between columns on screen and in PDF
A frame with Column Rule on gets a bar centred in each gutter, inside the
insets, broken around paragraphs that span columns; right-to-left and
vertical frames included. object.textFrameOptions takes columnRuleWeight
and columnRuleColor (unknown swatches are an error) and an inset array
whose null sides stay; document.inspect reports the rule.
* Text Frame Options: Column Rules fields; OK changes only edited fields
The dialog shows the selected frame's options, with an inset field per
side, and sends only what the user changed, so unequal insets survive.
The rule weight is read in points.
* Column rules: tint, horizontal offset and top/bottom insets; IDML import and export
Text Frame Options gains Tint %, Top Inset, Bottom Inset and Horizontal
Offset for the rule, and object.textFrameOptions and document.inspect
take and report them. IDML reads the ColumnRule attributes of
TextFramePreference on frames and object styles and writes them when a
rule is set.

- An RGB image with no ICC profile of its own was written as DeviceRGB
under the CMYK output intent, and the export only warned. In PDF/X-4
it now carries the sRGB profile (assets/icc/sRGB-v2-magic.icc, ICC
v2.1, CC0). JPEGs stay passed through. Untagged PNG, GIF and WebP,
and the decoded TIFF, BMP and PSD fallback, go in as RGB with the
profile. A re-encoded JPEG keeps the source's RGB profile or gets
sRGB. Grey images and images with their own profile are unchanged.
- Every image constructor asked for interpolation. PDF/X-4 and PDF/A
exports now write images without it, which also removes the
ImageInterpolation error that stopped PDF/A exports with a placed
image. Plain exports keep it.
- make_pdfx4 writes pdf:Trapped False into the XMP, matching
/Trapped/False in the document information.
- check_pdfx4 reports an image that asks for interpolation.

A placed PNG, GIF or WebP that is cut off (an interrupted download) or
has a bad checksum made the whole PDF export fail with
"PDF writer error: Image(Image(ImageRepr {..}), None, "unexpected end of
file")", which names no file. A damaged TIFF or BMP in the same place is
skipped with the warning "image `name` could not be decoded and was
skipped", and the rest of the document is exported.
The exporter decides whether an image can be embedded by asking krilla
to open it. krilla opens PNG, GIF and WebP lazily: it reads the header,
accepts the file, and decodes the pixels only when the PDF is written,
where an error ends the export. TIFF and BMP are decoded by us first, so
they took the skip path.
lossless() now decodes the image first for every format. A file that
does not decode returns None and takes the existing skip-with-warning
path. This costs one extra decode per PNG, GIF or WebP asset: the sample
magazine (two PNGs, 820 KB) exports in 0.19 s instead of 0.17 s in a
debug build.
