Each artboard can carry a guide label: one of the layer colors or a
custom RGB. Guides that belong to an artboard draw in its label color,
and guides without an artboard, or on an artboard without a label, keep
the guide color from the preferences. Selected guides still draw in the
selection color.
- Artboard Options has a Guide Label row (None, the layer colors with
swatches, or Custom with a color swatch).
- artboard.new and artboard.setProps take guideLabel: null, a layer
color's name, or #rrggbb. Any other value is an error. The inspect
summary lists guideLabel when one is set.
- The native format saves the label and skips it when unset; a preset
index outside the layer colors reads as no label.
- artboard.setProps no longer adds an undo step when nothing changes.

An image in a DeviceN color space opened as an RGB image, losing its inks.
One of one colorant now opens as a Separation image does since #6347: a
grayscale image of its tints colorized by its ink. One of two to 32
colorants that are all process plates (the ink None may be among them)
opens as a CMYK image, each colorant's tint in its plate, its Decode array
applied (8 or 16 bits a sample). A DeviceN image that mixes a spot ink
with other colorants, such as a duotone, still opens as RGB.

An image in a Separation color space opened as an RGB image: its spot ink
was lost (no plate in Separations Preview), and Fill and Recolor Artwork
didn't reach its color.
It now opens as a grayscale image of its tints (white where it lays no
ink, black at 100 %, its Decode array applied; 1 to 16 bits a sample, or
one gray channel from its JPEG, CCITT, JBIG2 or JPEG 2000 decoder),
colorized by its ink at 100 %: the spot swatch, a process plate's CMYK
color, or Registration. Its mask becomes its opacity mask, as a CMYK
image's does. The ink is found by the image's color space among those the
file defines, once per image. The ink None, an ink whose color can't be
told, images inside an alpha soft mask, inline images and DeviceN images
open as before; samples that can't be read open in RGB with a warning, and
the ink gets no swatch.

Editable PDF import derived characters from glyph Unicode/CID mappings
even when the enclosing marked-content sequence supplied /ActualText.
A span that paints "xy" but says "AB", followed by "C", imported "xyC".
Track the outermost replacement owner per span (absent, explicitly
empty, consumed), decode it with the existing PDF text-string decoder,
emit it once at the first placeable glyph, and let the remaining glyphs
of the span advance the pen without phantom character slots or
inferred spaces. Authored stretches keep their logical order while
adjacent ordinary text still goes through visual-to-logical
reconstruction. Glyph identity still drives font matching. Depth and
size are bounded; oversized or unbalanced spans fall back to glyph
mappings with a warning.
Outlines mode and PDF export are unchanged. Parity docs updated,
scores unchanged.
Fixes#6165.
A PDF image mask (`/ImageMask true`) painted in a solid color opened as an
RGB image with the color in its pixels: Fill and Recolor Artwork didn't
reach the color, a spot color lost its ink, and the same mask painted again
in another color took the first one, because the painted image was cached
by the mask alone, and so did an uncolored pattern whose cell draws a mask.
It now opens as a grayscale image of what it paints, colorized by that
color, as the .ai reader opens a 1-bit image mask (#5790). A spot color
keeps its swatch and tint. The page's walk counts paths, not images, so the
ink is found from the color space. Readings of a pattern cell are told
apart by colorized images' colors too. Inside an alpha soft mask, or
painted with a pattern, a mask opens as before.

A PDF names a ligature's characters in logical order (lam then alef for
the lam-alef glyph), while a horizontal line of type is gathered glyph by
glyph in visual order and then put back in logical order character by
character. The ligature's characters were turned round with the line:
لا came in as ال, بلال as بالل and الله as هللا. Each glyph's
characters now go into the line in visual order, so putting the line back
restores them.
A PDF-compatible .ai (or a PDF saved with the editing data) now opens
from its layers without its PDF part being imported, and without being
compared with its page, when:
- its text document makes the type of every text object, hidden ones
included, at least one text object shows, and none is drawn by the
appearance of the layer or group it is in;
- its layers hold no unread object, no placed file with a second
placement and no live envelope with drawn art to fall back on, and
no image too large to read;
- it declares no large canvas, and its artboards are its pages' trim
boxes one for one, in points or in the first page's UserUnit.
A file whose layers draw differently from its page then opens from its
layers instead of its PDF part. The bleed comes from the pages' bleed
boxes. The check runs only when no pages are picked, layers and the
editing data are on, the crop box is asked for and type comes in as
text. Files saved without PDF compatibility, files whose PDF part
draws only type or nothing, and files whose PDF part's content can't
be read take the same path when they qualify: their bleed comes from
the pages' bleed boxes, pages in units larger than a point draw them
at their size in points, and the note that the PDF part couldn't be
read is not given, since its content is not read.
Files that don't qualify open as before, and the editing data decoded
and read for the check is reused after the PDF part is imported
(layered_ai_from).
When a file whose PDF part can't be read is scaled up to its size in
points, its text wraps are now laid out again at that size, and the
default graphic styles of a file without graphic styles of its own are
no longer scaled. The same applies on the new path.
Opening a .ai or a PDF read and checked the whole file up to five
times: for the document it carries, for whether it holds the editor's
private data, for the import, for the editor's copy and for its File
Info. Each pass parses the file and walks every object, about 190 ms on
a 15 MB .ai.
- vectorcraft_pdf::open_pdf reads and checks the file once, on the
import's deep-stack thread, and import_opened imports pages from that
reading. document.open takes the carried document, the page count,
the editor's copy and the File Info from it. The editor's copy is read
after the page import and only when the file is not restored from a
carried document; so is the File Info.
- A .ai saved without PDF compatibility opened with pages that name
every page reads its editor's copy from the same reading.
- document.pdfInfo reads the file once for its pages and the thumbnail.
- The Open and Place dialogs read the file once to decide whether to
ask for pages, instead of twice.
A file whose PDF part fails the check still reads its editing data
separately, as before.
The import read each form's /Group /I and /K from the file in order and
matched them to the transparency groups the interpreter pushed. The
interpreter draws a group that adds nothing (full opacity, Normal, no
mask, neither flag) straight onto its parent without pushing it, so every
group after one took another group's flags. Blend steps written as a
knockout group of falling opacity then painted over each other and drew
as solid dark shapes instead of light rings.
The interpreter already reports the flags right after pushing a group
(set_knockout, set_isolated); the import now uses those and drops the
file-order list. That list was capped at 10,000 entries, past which a page
failed to import; that limit goes with it.
Patch and triangle mesh shadings of more than 4,096 patches, and strokes
painted with a mesh shading, came in as a flat grey. Illustrator writes
meshes of up to 14,355 patches, and writes a freeform gradient on a
stroke as a stroke painted with a type 7 shading.
- MAX_PATCHES is 16,384, as in the .ai editing-data reader.
- A stroke painted with a mesh shading is the meshes clipped to the area
the stroke paints (stroke_outline: width, caps, joins, miter limit and
dashes, built in the path's space and then transformed); draw_meshes
always clips a stroke's meshes.
A page drawing one form over and over made its art again for every drawing
with no limit (a 1 KB file took 877 MB), and a form decoding to 64 MiB drawn
a thousand times hung. The import now makes at most half the objects a saved
document may hold (2M, 256K on the web), leaving the rest out with a warning,
and the scan reads at most 2 GiB of form content per page before refusing it
as past the reader's limits.
