An image in a four-component ICCBased color space opened with its ink
amounts but without the profile its color space holds, so PDF export
could not write it in that profile again.
- The profile is read from the color space stream (at most 16 MiB) and
kept when it is a well-formed CMYK profile. A CMYK TIFF carries it as
tag 34675; a CMYK JPEG kept as it is carries it in ICC_PROFILE APP2
segments in place of its own, with its compressed data unchanged, and
one whose segments cannot hold it is stored as a CMYK TIFF.
- jpeg_with_icc passes over fill bytes (0xFF before a marker, ITU T.81
B.1.1.2) and leaves them out of the output.
- A malformed, non-CMYK or larger profile leaves a decoded image's TIFF
untagged and a kept JPEG as it is. DeviceCMYK and DeviceN images stay
untagged.
- A CMYK TIFF's tag 34675 is read up to 16 MiB; before, a 4 MiB profile
was read back and a 16 MiB one was not. The comments of
tiff_icc_profile and source_icc give that limit.
An Abutting trace with Fills now holds a "Seam Fills" group under its
paths. For each color it has one stroke, 1.5 image pixels wide, along
the edges where a filled path of that color meets a filled path drawn
after it, in that color. A renderer that anti-aliases each path on its
own no longer shows a light hairline along those edges. The traced
paths and their shared edges do not change, and edges against the
image's border, a transparent area or a color left out get no stroke.
- vectorcraft-trace: `seam_fills` finds the segments two filled paths
share and strokes them in the lower path's color (one stroke per
gradient path). Overlapping, traces without Fills and Flat Logo get
none.
- Image Trace commands: the group comes under every path (right above
the hidden image in a live trace). Expand keeps it, Expand by color
leaves it under the color groups, and a trace whose paths have more
than half of the anchor limit gets no seam fills.

The dialog opened without the custom, entry and char fields, so
ui.dialog.set refused them until Custom was clicked or an entry typed.
The spec now lists them in its inputs, and the dialog opens with
custom off and an empty entry.
Variable Options in the Variables panel only renamed a variable, and no
command changed a variable's kind. variable.rename now takes
{name, newName?, kind?} and renames the variable, changes its kind, or
both, in one undo step, with none when nothing changes. A null or empty
value, an unknown kind, a taken name and locked variables are refused.
A kind change unbinds the objects that can't hold the new kind (text
keeps type with no other text variable, image keeps image objects,
graph keeps graph roots, visibility keeps every object) and drops the
variable's values in every data set. The dialog shows the variable's
name and kind and sends both.
- CMYK colors converted between two loaded CMYK profiles now use the
Color Settings black point compensation, as RGB colors already did:
the conversion goes through linear ProPhoto RGB and maps the source
profile's black onto the destination's.
- The edit.colorSettings, document.open and file.newFromTemplate params
text and docs/mcp.md name file.newFromTemplate with the commands that
apply the policies, and say that colorMode on open converts after the
policies, through the profiles the document keeps.
- A test covers New from Template under the policies, and another the
CMYK black point compensation.
A linear or radial gradient of CMYK stops drawn as an image (a dithered
fill, or a Perceptual gradient that is not written as a spot shading)
was written as an RGB image whenever any stop was linked to a spot
swatch, even a stop that colors nothing: one inside fully transparent
stretches, one out of order between stretches with no width, or one at
a tint of 0 without process plates. The spot color warning already
skipped those stops.
The image now falls back to RGB only when a stop prints a spot ink, the
same test the warning and the spot shadings use. A drawn spot stop at a
tint above 0, or with process plates, still gives an RGB image with the
warning.
Automatic counted flat art's colors with a median cut that never splits a
box narrower than 24 levels, so evenly spaced levels about 17 apart (gray)
or 13 apart (sepia) shared boxes: 16 clean gray levels traced in 14 colors
and 16 sepia levels in 9.
When flat art's pixels fall in 2 to 16 histogram bins, each holding at
least the share a color needs to be counted, and every two bins lie at
least 12 levels apart on some channel, Automatic now takes one color per
bin. If mixed-color merging then finds two of those colors mixed through
each other (dithering, or a thin region beside a close level), the picture
is counted by median cut as before, with rare colors added.
Anti-aliased art whose levels lie more than 20 apart is counted level by
level too, because its blended edge pixels are left out of the count.
Noisy pictures, anti-aliased art whose levels lie 20 or fewer apart and
pictures of 17 levels or more are counted as before, and continuous-tone
classification is unchanged.
object.distribute uses spacing with a key anchor, and to: "selection" or
"artboard" makes the key anchor an ordinary point. docs/mcp.md and the
object.distribute and object.distributeSpacing params text still said
both commands ignore to and spacing with anchor points selected.
