- 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.
The symbol instances the picker reads now share one limit of 16,000,000
placed objects, charged through charge_symbol_art and counted as the
renderer counts them, so deeply nested or heavily repeated instances
stop there. An instance whose art would pass the limit is left out with
its own paints, as the canvas draws none of it. Pattern tiles carry the
count in and out, and their art is read one level deeper than the
object the pattern fills, so a chain of patterns shares the depth limit
with the art around it; a pattern cut short there is read again where
it is used less deep.
The pixels read inside clip groups are now tested against at most
4,000,000 clipping-path elements in all. The clipped reads of one image
share the work, a read outside clip groups keeps its own pixel budget,
and when the work left can't test a pixel of every clipped read, the
reads that fit are kept in order and the rest are left out.
ImageBlob::sample_pixels takes a pixel budget for each pick.
locate_within measured every boundary edge of the mesh at full accuracy
for each lookup, including points well inside the mesh. It now skips an
edge whose control points all lie farther than the distance it is
looking for: a millionth of a point for the outline, or the tolerance
for a point outside.
A point exactly on a gradient mesh's outline located on the top and left
edges but not on the bottom and right ones, where the nonzero winding
number is 0. object.mesh.addLine and Create Gradient Mesh at a point there
reported the point outside the mesh, and the Eyedropper did not sample it,
while the hit test selects the mesh there.
locate_within now takes the nearest point of the edge for a point within
a millionth of a point of the outline, with any tolerance, and returns
nothing for a point that is not finite. A point just outside still needs
a tolerance.
The Color Theme Picker button beside the Assign and Edit tabs turns on
picking from the canvas. A click takes the color palette of the object a
Selection tool click takes there, a drag takes the palette of the art
inside its marquee, and Shift adds more picks. The rows that are not
excluded take the palette as their new colors and the art previews them;
OK keeps the recolor as one undo step.
- recolor.pickTheme {picks, colors?} returns the palette of the art
picked: visible fills and strokes, gradient stops, text, mesh points,
pattern tiles, symbol art, colorize colors and image pixels. Clip
groups, clipping opacity masks and isolation mode limit it to what
shows, and it changes nothing.
- Each object read weighs the same; similar colors merge (k-means in Lab)
into at most `colors`, most used first. Image reads are bounded (65,536
pixels a pick, 1,048,576 pixels and 64 images in all), and past 4,096
distinct colors, close colors merge before clustering.
- The dialog's themePicker and themePicks fields drive it from
ui.dialog.set. A new Colors count keeps the picks.
A click just past the end of two segments that meet with almost no
turn, as the segments of a warped edge do, missed a beveled or mitered
stroke: the joint has no bevel, and the check counted that as a miss.
It now counts as painted, so the eyedropper samples an envelope's
stroke there again.
A miter join on a stroke whose dashes have round or projecting caps
still paints the miter spikes the limit keeps, and the visual box
includes them. object.setBounds with Use Preview Bounds did not count
such a stroke as one whose margins follow its segments' directions, so a
closed path at a slant missed the size typed when the width and height
were out of proportion.
A bevel join, and a miter join whose miter limit bevels a corner, end the
stroke at the outer corners of the two segments they join. The visual box
measured such a corner as if the stroke reached half its weight round it:
a 40 x 100 pt triangle with a 20 pt stroke and a miter limit of 2 measured
10 pt above its tip, where the stroke paints about 1.96 pt above it. Use
Preview Bounds, and the alignment and sizing that use it, took that box.
- With bevel and miter joins, closed paths and open paths with round or
projecting caps are now measured along their segments, as butt-capped
open paths already were, with the miter tips the limit keeps and the
caps added. Round joins still reach half the weight round each corner,
the round caps of dashes, which can end at a corner, reach half the
weight all round, and the projecting caps of dashes reach the diagonal
of their square. The visual box of
such a stroke can be smaller than before and is never larger. A path
with no width, such as a rectangle sized to 0 pt wide, turns back at
its ends, where the join bevels, so its box no longer reaches past them.
- object.setBounds with Use Preview Bounds measures an object as drawn
when a beveled or mitered corner, or a butt cap, is on a segment at a
slant. Before, a closed path with miter spikes the limit keeps missed
the size typed when the width and height were out of proportion.
- A click past a bevel or a butt cap, by more than the click tolerance,
no longer selects the stroke. Strokes with a width profile or with
dashes that have round or projecting caps, and the ends of curves that
bend more tightly than half the weight, keep the round reach.
- Paths measured along their segments skip the segments that cannot
reach past the box measured so far, which starts with the path's own
bounds.
When a blend starts a key's path elsewhere (an open path clicked at its
last anchor, a closed path turned to another start or reversed to match
the other key's winding), the steps now read that key's width profile,
pen pressure, tilt, bearing and rotation along the turned path, and a
reversed open path's arrowheads swap ends. A width profile's sides swap
when its path is reversed, a closed path's samples move past the new
start keeping the step at the old one, and a split width span is sampled
so its curve keeps its shape. A key whose subpaths turned differently
keeps its stroke as it is.
Width profiles in the steps also keep their discontinuous points instead
of only the width before them, and are sampled between their points so
each key's curve keeps its shape where the other key adds points; keys
whose points sit at the same positions are not sampled, so a preset on
both keys stays that preset. A sample of one key that lies within a
millionth of the other key's step no longer hides that step.
Paragraph panel menu > Bunri-Kinshi (with the East Asian options) and
text.setFormat {bunriKinshi} turn it on per paragraph. A line then
never breaks inside two em dashes, two horizontal ellipses, two two-dot
leaders or the two halves of a vertical kana repeat mark, the pairs W3C
JLREQ lists for class cl-08 (https://www.w3.org/TR/jlreq/#cl-08), nor
inside a chain of em dashes. Both composers, vertical type, Kinsoku
Shori Type, hyphenation and No Break follow it, and a pair wider than
the line stays whole on it. Justification and letter spacing add no
space inside a pair.
The setting works only with a Kinsoku Set: with Kinsoku Set None the
paragraph keeps the value without effect and the menu item is
unavailable. It is off by default, saved with the paragraph only when
on, carried by paragraph styles (Paragraph Style Options > East Asian
Composition Settings), and turned off by Reset Panel. A value that is
not true or false is refused. The .ai editing data has no field for it,
so saving reports a paragraph with it on and a pair in it as left out.
Docs: docs/mcp.md, docs/target-app-parity.md.
Characters take two new attributes, `akiLeft` and `akiRight`: space
before and after each character in reading order, in thousandths of an
em from 0 to 1000, measured as tracking is. `text.setFormat`,
`text.setRangeStyle` and character styles set them; values that are not
numbers or are outside the range are refused, and a file holding one
outside the range opens with the nearer end. Both are saved only when
not 0.
- Layout: Left is the space above a character in vertical type and on
its right in right-to-left type. Wrapping counts the space, a line's
end keeps it when aligned, and justification and Optical kerning
leave it at its set width. A ligature, a letter with its marks and a
tate-chu-yoko block take the values of their first character.
- With Fractional Widths off or System Layout on, the space before and
the space after a character are each set in whole points and added
to its rounded width, so justification keeps them at that width. A
tate-chu-yoko block rounds the space above and below it the same way.
- Character panel: with Show East Asian Options on, Insert Aki Left and
Insert Aki Right fields with 0, 250, 500 and 1000 in their menus;
Reset Panel sets both to 0.
- Character Style Options › Advanced Character Formats shows Insert
Aki Left and Insert Aki Right, with the Character panel's 0, 250, 500
and 1000 in their menus; a typed value below 0 or past 1000 sets 0 or
1000, and Reset Panel unsets both.
- SVG export: live text places each character the space moves, and
type on a path with Insert Aki is written as outlines.
Docs: docs/mcp.md, docs/target-app-parity.md.
File › Place with Link reads a DCS 1.0 or 2.0 file (an EPS file whose
header names one EPS program per printing plate) as one linked image of
its plates. Each spot plate adds a spot swatch in the CMYK values the
file gives, and the clipping path the file's composite is drawn through
clips the image. document.open, file.place without link or from bytes,
and links.embed refuse a DCS file and change nothing.
- The screen, composite print and exports show the plates mixed into
CMYK. Separations Preview and print separations show each plate on
its own ink; a spot plate prints as its CMYK values when spots print
as process.
- links.list answers the format DCS, and with dcsTransparency marks the
DCS images that are transparent or overlap transparent objects (the
Links panel menu's Show DCS Transparency Interactions).
- swatch.unused leaves out a spot swatch while a DCS image has a plate
of its ink.
- links.update and links.relink read the plates and the clipping path
again, and the link shows as modified when one of its plate files
changes or is gone.
- The plates go on the first plate's pixel grid, grown to hold every
plate where it prints; a plate of another size or position is
resampled onto it.
- A file may name 64 plates, a plate file may be 1 GB, and the plates
together may hold 512 MB of ink amounts. A file naming more plates is
an error.
Docs: docs/mcp.md, docs/target-app-parity.md, docs/file-format-parity.md.
A blend between two strokes drawn with a pressure-sensitive brush gave
every step the pen recording of the nearer key, so the brush jumped at
the middle step. The steps now interpolate the pressure, tilt, bearing
and rotation at every position either key has a sample. A key without a
recording counts as half pressure, half tilt and 0 degrees, as brushes
read it. Angles turn the shorter way round, and steps and whole turns in
a recording stay in the steps. Different brushes still switch halfway.
- A live color adjustment recolors a masked image's masked pixels, on the
canvas and in outputs that apply the adjustment, so the colors the mask
hides stay hidden. Before, the adjustment recolored the image's own
pixels and the hidden colors showed again.
- An envelope warp gives each piece of a masked image the image's color
mask, so the warped image shows its masked pixels.
Tests: a_live_color_adjustment_keeps_the_hidden_colors_hidden and
an_envelope_warp_draws_the_masked_pixels.
A linear, radial, conic or diamond gradient has a spread: Pad (the
default, as before), Repeat or Reflect, with a count of 1 to 100
(VectorCraft's own limit). Repeat and Reflect run the stops that many
times along the vector (around the turn for a conic) and keep going past
both ends, Reflect running every other run backwards, as SVG's
spreadMethod does.
The Gradient panel has a Spread menu and a Repeats field, and the
Gradient tool marks where the runs meet. paint.setFill and
paint.editGradient take `spread` and `repeats`; bad values are errors.
Presets, swatches, blends, strokes along or across a path, Outline
Stroke and Object › Expand follow the spread; Expand gives each run the
same whole number of objects, and Outline Stroke's mesh keeps the color
on each side of a sharp step between two stops at one offset.
SVG writes and reads spreadMethod: SVG import now reads a repeating or
reflecting gradient as one that repeats or reflects once, instead of
expanding its stops over the shape. CSS writes repeating gradients.
PDF writes a conic's sweep shading over one run. PDF, EPS, legacy .ai
and the .ai editing data write the other kinds with their stops
repeated across the shape: at most 256 runs and 16,384 stops (256 stops
in .ai files), and for a radial or diamond no farther than 65,536 runs
from its center, with a warning past those. PDF import now finds sharp
steps in any axial or radial shading instead of blurring them.
Docs: docs/mcp.md (Spread), docs/target-app-parity.md, docs/gaps.md.
- The legacy .ai and the check for see-through images in pattern tiles
read a color-masked image's masked pixels, as the flattener does. A
legacy .ai flattens a masked opaque image with the art under it, or
leaves it out with `transparentImages: "omit"`, and a pattern tile that
holds one is expanded before PDF/X-1a, PDF/X-3 and legacy .ai output
flatten it.
- Printed separations check whether a colorize paint shows on the masked
pixels, as the canvas does, rather than on the image's own pixels.
- A saved mask that leaves out `contiguous`, `tolerance` or `softness`
reads them as the command's defaults: true, 10 and 10.
- Remove Background is unchanged on this branch. Its refusal of a
grayscale image colorized with a process color is left for a separate
pull request.
Tests: legacy_ai_flattens_a_masked_image_as_a_see_through_one,
a_pattern_tile_with_a_masked_image_counts_as_see_through,
pdf_x1a_and_x3_flatten_the_hidden_pixels (PDF/X-3 added),
separations_colorize_masked_pixels_whose_own_pixels_are_a_preview,
a_record_without_settings_reads_the_defaults, and the dialog's query on a
linked image at its preview.
A four-component JPEG whose EXIF orientation turns or flips it went
through the image decoder, which reads CMYK JPEGs as RGB, and was
stored as an RGB PNG without its inks. It is now stored the way a
turned CMYK TIFF is: its inks, 8 bits each, turned and written as a
CMYK TIFF with the turned resolution.
- vectorcraft_doc::cmyk::turned_cmyk turns the inks of a CMYK JPEG or
TIFF, next to stored_cmyk_tiff; tiff_inks is private again.
- raster_image swaps the resolution axes inline, as its HEIF branch
does.
- The links comment and the docs/target-app-parity.md line on EXIF
orientation now describe the turned CMYK TIFF.
