stops and stop flattened the path twice, once for the points and once
for its length, and stop did both before rejecting an index past the
last object. place validated the path with attachable_path first, and
transform measured the old and new paths up to three times each.
A private Measured value now holds the flattened first subpath with its
length and closed flag, and path_length, stops, stop and transform use
it. stop returns None for an out-of-range index without measuring, and
a move of the group measures no path.
attachable_path now uses path_length, so a path whose length overflows
to infinity is no longer offered as one objects can attach to when
placement cannot measure it.
In SVG and PDF output, each piece of a warped image whose pieces can show
through was drawn through a mask of every later piece that reaches it. On a
later piece's antialiased edge the viewer multiplies the earlier piece's
coverage by the mask and draws the later piece over it, so an image with
both opaque and partly transparent pixels came out lighter at its opaque
pixels along the triangles' edges (alpha 184 of 255 in the new SVG test).
A later piece now goes into an earlier piece's mask only when a pixel of
either piece's image within 2 pixels of their overlap is less than opaque
(vectorcraft_effects::WarpSeams). Where two pieces overlap over opaque
pixels, the later one is drawn over the earlier one without a mask.
Type with an inline graphic was resolved only in the layers, so type in
the art of another symbol, a graph design, a pattern tile or an opacity
mask kept the size its graphic had when it was made. The symbol holding
that type, its instances and the inline graphics that show it were
measured from the stale layout.
- Inline graphics are resolved in every tree that holds type. Symbols
are resolved in dependency order, so a symbol's type is laid out
before the type that shows that symbol inline. Edits, opening,
reverting and Refresh Font List use the same pass.
- The pass visits each object once: it resolves the children first and
copies a node only when something below it changed. It measures each
symbol's art once per pass.
- An inline graphic of a symbol whose art shows that symbol inline,
directly or through other symbols, is an empty slot. The symbols on
such a cycle are found once and cached until the symbols change.
- A changed inline graphic also clears the text's cached baselines.
Edit > Edit Colors > Convert to Indexed Color... (edit.colors.toIndexed)
stores the embedded images in the selection as indexed-color PNGs: a
palette of at most 256 RGB colors, each pixel the index of one. The
dialog previews live and OK is one undo step.
- The palette is chosen as for a PNG-8 export (selective, perceptual,
adaptive, web, gray, black and white), as evenly spaced levels of red,
green and blue (uniform), or from the document's swatches. Dithering
is diffusion, pattern, noise or none, with an amount.
- Pixels under half opacity become one transparent entry; the others
become opaque in their own color. Linked images, colorized images and
color glyph images keep their pixels.
- An image that is already an indexed PNG and would show the same pixels
is left as it is, and no undo step is recorded when no image changes.
- An image of more than 134,217,728 pixels (33,554,432 in the web app)
is refused, read from its header before decoding.
- With Select All, locked and hidden objects that hold an image that is
not an indexed PNG yet are counted in notChanged, without converting
them.
- The quantizer gains quantize_to, which maps pixels to a given palette.

An envelope around type of only spaces and a rectangle mapped from the
union of the rectangle and the type's laid-out box, so the empty type
moved and scaled how the rectangle was distorted. Type that draws
nothing now adds no box while other content in the envelope has one,
in groups and layers and as a clipping path too. When nothing else in
the envelope has a box, the type keeps its laid-out box, so an envelope
of only empty type keeps its frame, Make with Mesh and Reset with Mesh
still work, and Release still gives back the warp shape.
This applies to Make with Warp, Make with Mesh, Make with Top Object,
Reset with Mesh, Edit Contents and the stroke margins. Type that has
not been measured yet keeps its laid-out box as before.
The PDF/.ai import's boxes for envelopes with Distort Appearance
measure each object as the whole contents measure it, so the margins
the import tries match the contents' geometric box. The three import
tests that measure type without registering the glyph measure now
register it first, so another test registering it while they run no
longer changes their result.
An envelope or the Warp effect cuts an image into triangle pieces that
reach a little past their edges, so neighbors overlap and no seams show.
On an image with alpha, the overlap drew that alpha twice: a 50% image
came out about 75% opaque along every cell edge and diagonal.
- The pieces now form a knockout group, and each piece is marked as a
warp piece (`warp_piece`) whose knockout shape is its whole triangle,
so where pieces overlap only the top one draws.
- The canvas knocks each piece out by its triangle at full coverage.
- SVG and PDF draw the pieces of a partly transparent image (its pixels,
opacity, color mask or colorize paint) through one mask each, of the
later triangles that reach it; pixels on a triangle's antialiased edge
come out slightly lighter there. Pieces of an opaque image are drawn
one over another as before.
- SVG writes one copy of the image for pieces cut by opacity masks
(Preserve Shape Using Transparency) too.
- A cell count past the generated-object budget makes an empty group
instead of overflowing.
Docs: docs/target-app-parity.md.
Open and Place store some images again instead of keeping their bytes:
a photo turned by its orientation, a TIFF the image decoder reads, and
a CMYK TIFF with one plane per ink. Those images lost the ICC profile
their file embeds, and 16-bit samples were cut to 8 bits.
- raster_image keeps gray and RGB samples at 8 or 16 bits in the
stored PNG, with the gray or RGB profile in its iCCP chunk. A
profile of another color space, such as the CMYK profile of a CMYK
image read as RGB, is left out. A TIFF's profile is read with the
tiff decoder, which reads it whatever the image's size.
- stored_cmyk_tiff and turned_cmyk write CMYK8 or CMYK16 as the file
has it, with the CMYK profile as TIFF tag 34675 (UNDEFINED). A CMYK
JPEG's profile is put together from all its APP2 segments.
- The docs/target-app-parity.md line on EXIF orientation says 8 or 16
bits, and a line after it describes the kept profile.
Object > Path > Remove Anchor Points removed each selected anchor with
its own Vec::remove, shifting the rest of the subpath every time, so
removing k anchors from an n-anchor subpath took O(k*n) moves.
- pathops: remove_anchors removes a subpath's anchors the last first,
reading each anchor's current neighbors, handles, length and closed
state as removing them one at a time does, and compacts the anchor
list once. remove_anchor and remove_anchors share one refit, so the
result is bit for bit the same.
- engine: the command groups the selected anchors by subpath, works out
the next selected anchor with each subpath reading only its own
selected anchors, and takes emptied paths out of the selection
together (Selection::remove_all).
- Tests compare remove_anchors bit for bit with remove_anchor over 600
generated subpaths and focused cases, count the anchors moved (2001
anchors, every other one removed: at most one move per anchor left,
500,500 one at a time), and compare the next-anchor selection and
the command on many paths and subpaths with removing one at a time.
An <image> whose EXIF orientation or TIFF Orientation tag turns or flips
its pixels, linked or as a data URL, is turned before usvg reads it: the
pixels are stored as they are shown, the width and height swap, and the
box fits the turned image under preserveAspectRatio, as CSS
image-orientation: from-image describes. A turned CMYK JPEG or TIFF keeps
its inks as a CMYK TIFF, as does a CMYK TIFF that is not turned.
- Data URLs of type image/tiff, and untyped TIFF bytes, are read.
- TIFFs with extra channels, CCITT Group 3 TIFFs and planar CMYK TIFFs
are read as Open and Place read them.
- Converted images decode within the decode allowance, and a TIFF that
claims more strips or tiles than the decoder can count is refused
before any decoder opens it.
- exif_orientation moves to vectorcraft-doc so Open/Place and SVG import
share it.

Spine::at_length walked the first subpath's segments from the start
until one ended at or past the arc length, so placing every blend step,
spread key, blend widget and Objects on Path attachment cost one
comparison per earlier segment. It now searches the anchors' arc
lengths, which never decrease, and picks the same segment: the first
whose end is at or past the length, so an exact anchor length and
repeated lengths from zero-length segments keep their segment. The
point and tangent evaluation is unchanged.
Tests compare the search with the old walk on open and closed spines,
one segment, curves, zero-length segments, every anchor, both ends,
out-of-range and non-finite lengths, and check that a 4,096-segment
spine needs at most 13 comparisons.
The previous commit took the spans from how far each piece bends away
from the split whenever both handles there were within ONE_CURVE of the
anchor. A curve that barely moves at the split but doesn't bend there
(a straight one, say) has short handles and no bend, so that gave 0/0
and the side fell back to the polygon shares. Now the spans come from
whichever pair is the longer: the handles, or the bends (which go with
the squares of the spans). The check of every piece against the
rebuilt curve is unchanged.

A blend made with Create Spine set to Never now shows the Appearance
widget with the Selection and Blend tools, so its color Shift can be
dragged on the canvas as on a blend with a spine. The Easing widget
stays hidden, since easing needs a spine.
The widget sits 16 px above the halfway point, by length, of the
straight lines between the key centers that the steps are laid out
along, and a drag follows those lines' direction there. The lines are
not drawn. `blend_layout_line` exposes that line; `blend_spine` still
returns `None` for such a blend.
Split where the curve stops (a cusp), both handles at the split lie on
the anchor, so their lengths say nothing of how the curve's parameter
divides between the two pieces, and the side fell back to the polygon
shares. When both handles lie within ONE_CURVE of the anchor, the
spans now come from how far each piece bends away from it (the second
derivatives, in proportion to the squares of the spans). The existing
check of every piece against the rebuilt curve is unchanged.

A live-effect plug-in that paints its pieces draws each piece's brushed
stroke along the piece's path at the piece's stroke width. Culling left
room for brush art from the object's own stroke width around the
pieces, so brush art of a moved or wider piece was cut off at the edge
of the view. Culling now leaves 16 x the piece's stroke width + 8 pt
past each brushed piece, and does so for a symbol instance whose art
holds such a path (measured once per symbol) and for a blend, envelope
or repeat that holds one. Object > Rasterize measures the brush art
drawn along each piece and leaves out the object's own brush art, which
is not drawn.
Groups and layers now leave room for their members' brush art. The
cull bounds of a group or layer united its members' bounds without the
room each brushed member leaves, so the painted bounds of a group, and
the area redrawn when it changes, left out brush art past its members'
strokes. That applied to plain brushed paths as well as painted pieces.
Each member is now measured as the renderer measures it when it draws
the group, in the members of a group with a fill, stroke or adjustment
of its own and in a group with crop marks or Vector Halftone too.
A top-object envelope gives each piece of a side a share of the content
in proportion to its control polygon's length. When anchors split a
curve without changing its shape, the pieces' polygons don't divide the
side where the curve's own parameter does, so the envelope bent its
contents differently although its outline was the same: Add Anchor
Points on a top object moved the art, and a top object whose .ai mesh
saves each side's curve split into thirds drew its type up to about
half a point off its drawn art, which follows the whole curve's
parameter.
Coons::from_top_object now checks whether a side's pieces, from corner
to corner, are all pieces of one cubic. The pieces' spans of that
curve's parameter come from the handle lengths either side of each
split, the curve from the outer ends and handles, and every piece must
lie within 0.02 pt of the curve's piece over its span (each control
point). Such a side runs along that curve, by its parameter. Any other
side keeps the polygon shares, including a side only partly made of one
curve and a smooth side drawn in many pieces that isn't one curve as a
whole. Corners found from the outline can still move when anchors are
added, as before. Gradient meshes made from a path are unchanged.
Existing top-object envelopes with such sides redraw.
a_split_curve_moves_the_top_object_share_to_its_new_anchor, which
pinned the earlier behaviour, becomes a_split_curve_keeps_the_top_object_patch.

The kept grid now records whether a type measure was registered, so a
grid built before registration is not reused when the registered inputs
number happens to be 0.
With both guides of an axis past the same edge, the art keeps its size
from the other edge of the instance, or shrinks to the instance's width
or height when the instance is smaller than the art. The module doc,
AxisMap::new and the docs/target-app-parity.md entry now say so.
A selected warp envelope now shows the points of its surface on a 4x4
grid (8x8 or 16x16 where 4x4 strays more than 0.1% of the warp's
diagonal from it). object.mesh.movePoint, movePoints, addLine,
deletePoint and object.envelope.setMeshPoint accept a warp: the first
edit turns it into a mesh envelope on that grid and applies the edit as
one undo step, so Undo or Escape gives the warp back with its style and
bend. An edit that moves no point leaves the warp and adds no undo
step. A warp that no such grid follows (some version 0 maps) shows no
points and its edits fail without changing anything.
movePoints and setPointColor on a gradient mesh record no undo step
when they change no point.
The Paragraph panel's Mojikumi Set lists None, YakumonoHankaku,
GyomatsuYakumonoHankaku, GyomatsuYakumonoZenkaku and YakumonoZenkaku,
then Line-end Punctuation Half Width, and text.setFormat {mojikumi}
takes yakumonoHankaku, gyomatsuYakumonoHankaku, gyomatsuYakumonoZenkaku
and yakumonoZenkaku besides none and lineEndHalf.
The spacing of each set is VectorCraft's own rule, built on the help
page's one-line description of each set:
- YakumonoHankaku sets every bracket, comma and full stop half width,
takes a quarter em off each side of a middle dot, and puts a quarter
em between Japanese and Latin letters or digits.
- GyomatsuYakumonoHankaku keeps punctuation full width inside a line,
sets an opening bracket starting a line flush and a closing mark
ending it half width, and takes the quarter em after a middle dot
ending a line off.
- GyomatsuYakumonoZenkaku keeps punctuation full width and adds the
quarter em between Japanese and Latin text.
- YakumonoZenkaku sets characters as None does.
Both composers and vertical type measure each line as it is set. A
right-to-left paragraph, whose line ends are measured untrimmed, also
draws them untrimmed, and a right-to-left line that ends between a
Japanese and a Latin character is measured without the quarter em the
set adds there. With a Desired glyph scaling other than 100%, the
space a set takes off before an opening bracket or middle dot, and the
Japanese-Latin space recorded at a line's end, scale with the glyph.
The sets save with the document and paragraph styles; new type and
Reset Panel keep Line-end Punctuation Half Width. SVG export lays type
with middle dots out again for its positioned spans. A .ai save
reports a paragraph with one of the new sets as left out.

Copy now remembers the whole chain of layers around each object, not only
the name of the nearest one. With Paste Remembers Layers on:
- In the same document, art goes back into the sublayer it came from while
that sublayer exists, even after it was moved, so two sublayers of the
same name in different layers stay apart. A deleted sublayer is made
again inside the layer that held it.
- In another document, the sublayer and the layers around it are matched
by name from the top level down; of repeated names, the topmost chain
that matches the most names wins, a shown and unlocked one first. A
missing sublayer is made inside its layer, and a missing layer on top
with the sublayer inside it, in the paste's undo step.
- When the matched layer, or a layer around it, is hidden or locked, the
paste fails with "the target layer is locked or hidden" and nothing is
pasted, instead of putting art in a hidden layer or making a second
layer of the same name.
The series fill and stroke and the label fill and stroke a graph keeps
for its next redraw are now in the paint traversal, so Delete Pattern
and canceling a new pattern make them no paint and a Pattern Options
rename renames them. Before, a later graph.setData drew the paint of a
missing pattern again. Global swatch edits reach the same paints.
The progress-doc line now says that only canceling a new pattern clears
its paints; canceling the edit of an existing pattern puts the
definition, and after a rename the old name, back.
A 9-slice guide can now be placed outside the symbol's art, by dragging
it past the art's edge in symbol editing mode, by symbol.options
nineSliceGuides, or by a Symbol Options field below 0% or above 100%.
A scaled instance then scales by the cells its art falls in.
- Each guide is a fraction from its edge in -16..16, and the two guides
of an axis keep their order (left + right < 1, top + bottom < 1).
- A guide past an edge cuts the art at that edge, so that side's outer
cell holds no art. With both guides of an axis past opposite edges,
the art scales as a whole along it. With both past the same edge, the
art keeps its size in the outer cell at the other edge.
- Symbol Options shows the guides with three decimals, and OK keeps a
field that was not changed at its exact value.
- Native files keep the guides exactly. SVG and .ai write such an
instance as its placed art, without guides.
Docs: docs/mcp.md, docs/target-app-parity.md, docs/gaps.md.
Linked images and placed documents kept only in symbols, graph designs,
pattern swatches or opacity masks now have ids of their own. links.list
lists them after the layers' own, one row per stored object, with an
owner naming what holds them; links.check, the missing, modified and
updated files reported on open, the link watch and links.findFiles
report them by id; relink (All Instances included), update, embed,
placementOptions, info and image.info act on them. links.goTo on one
clears the selection and returns onCanvas: false with its owner, and the
Links panel says the link has no place on the canvas.
- Document::visit_stored, stored_node and stored_node_mut find objects
in every stored art. fix_next_id counts their ids and gives an object
there whose id is 0, past the id range or already used a new one,
updating Objects on Path references to renamed children.
- Copies of masked objects give the mask art new ids, and symbols and
patterns that placed art brings from another document take ids of the
document they join.
- The Links panel picks such rows in the panel itself, drops the pick
when the canvas selection changes, and draws their thumbnails from a
lookup made once per list refresh. Select by Link Status leaves them
out, as it cannot select them.
- The link watch and links.updateChanged look at a DCS file's plate files
of their own, so a changed plate file is read again.
- links.update and links.relink apply the file's clipping path to the
images in symbols, graph designs, patterns and masks too. When the new
file has no clipping path, a clip group holding the old file's clipping
path loses that path and stays as a plain group of the image, keeping
its id, name, visibility and transparency. The image keeps that path with its plates to tell it from a
clipping mask made in the document; a clipping path given another fill
rule in the document stays. An even-odd clipping path in the file is
kept as the same area under the nonzero rule.
- links.update and links.relink return the swatch warnings file.place
gives, including two files that add one ink in two colors.
- links.relink with copy fails for a DCS file with plate files of its own.
- file.place answers the image id of a clipped DCS placement as image,
and checks page and crop for a DCS file as it does for an EPS file.
- Print separations and Separations Preview take a spot plate's color
from the document's swatch of its ink, and a reduced image's plates
keep their coverage.
- Show DCS Transparency Interactions counts a transparent DCS image and
characters filled or stroked with a transparent gradient.
- %%PlateFile names keep their spaces, and header bytes that are not
UTF-8 are read as Latin-1.
- A plate program that draws more than one image, art besides its image,
or its image through a clipping path is an error naming the plate
instead of printing the wrong ink.
- Nested clipping paths around the composite clip the image together.
- A kept image with more plates than are read, or more TIFF directories
than its composite and plates, is the CMYK image of its composite
only, not a set of plates cut short.
- swatch.unused counts a spot or process swatch as used only while an
image the art shows has a spot plate of its name.
Cancel on a pattern that Make created for the edit now removes every
swatch of it, a color group's included, and turns every paint of it
left in the document into no paint: art outside the editing layer,
opacity mask art, type runs, symbol definitions, graph designs, other
patterns' tiles (a copy Save a Copy made included), graphic and
character styles, brush art, and the fill, stroke and appearance new
art takes. Delete Pattern clears its paints in the same places, and a
Pattern Options rename renames them there; both reached only the
layers before. Delete's `unpainted` counts the document paints it
cleared.
Cancel after a Pattern Options rename during the edit gives the
pattern its old name back with its swatches and paints, unless another
pattern, swatch or color group has taken that name; before, the
definition went back to the old name while its swatches and paints
kept the new one.
Undo and Redo restore new art's paints with the document, including
the appearance inherited from the selection with New Art Has Basic
Appearance off. A rename preview that is replaced or canceled starts
again from the paints the interaction began with, and a canceled
preview takes the selection's appearance again.
