When a document opens or is reverted with dimensions whose art is not in
its color mode, the dimensions are drawn again before the document's
composite fonts are registered. A label whose font names a composite font
that another open document defines differently was measured in that other
definition, so it was centered off its anchor. The redraw now measures the
labels in the document's own composite fonts, in front and in the back.
A gradient's Separation or DeviceN space, and EPS's %%DocumentCustomColors,
named the spot ink of every linked stop. A stop out of order whose
neighboring stretches have no width, a stop at a tint of 0 without process
plates, and in PDF a stop whose stretches are fully transparent print no
ink, but their spot inks were still declared, so separations got an empty
plate.
- vectorcraft-color: Gradient::drawn_stops (the rule Document Info uses,
moved here) and Gradient::reached_stops (every stop taken as opaque).
- PDF: Separation and DeviceN shadings, the Perceptual spot shadings and
the spot-image warning name only inks of drawn stops at a tint above 0
or with process plates; other stops are written with no ink, so their
process inks and RGB or Lab colors no longer shape the space either.
- EPS: the same with reached stops, since EPS writes stops opaque; a
transparent spot stop keeps its ink.
Output is unchanged when every stop colors part of the gradient and every
spot stop has a tint above 0 or process plates.
Text on a path of one closed subpath that is anchored to start before
the path's start point (text-anchor end or middle, right-to-left start,
or a negative startOffset) started at the start point, and text offset
past the path's end started at its end. It now wraps around the path,
as SVG 2's startOffset attribute describes for a single closed subpath
(https://www.w3.org/TR/SVG2/text.html#TextPathElementStartOffsetAttribute):
text-anchor end at startOffset 0 ends at the start point. Open paths
and paths of several subpaths still start the text at the path's start
or end.
Checking an Extrude & Bevel (both kinds) or Inflate effect built every
shape's profile about the profiles' bounds, then built the fill and
stroke solids again about the bounds of the regions they paint. A
filled shape's profile is its fill's solid, so that solid was built
twice. When a stroke reaches past the shape, the first build also used
bounds the effect does not draw it about.
The check now builds the profile on its own only where no drawn solid
is built from it: every shape for Rotate, and for Extrude & Bevel and
Inflate a shape with no fill (strokes only, or no paint). A filled
shape's solid is built once, about the bounds the effect draws it
about. The shadow check is unchanged.
Tests count the solids the check builds: an object with a fill and a
stroke, a group of two such members, an effect on the fill and the
shadow on; a shape with no fill still has its profile built.
With `unicode-bidi: plaintext`, SVG import looked for the first strong
character of an element in each text node on its own and kept the
first answer. An isolate that opened in one text node and closed in a
later one hid the rest of that node, and the node then answered left
to right. For `⁧ab<tspan>⁩א</tspan>` the element
ran left to right, where UAX #9 P2 skips the isolate and finds the
right-to-left letter after it
(https://www.unicode.org/reports/tr9/#P2).
The characters of the whole `<text>` are now read once, in order, and
each isolate initiator is matched with its PDI (UAX #9 BD9). Each
element's first strong character is then found in constant time, so
nested `plaintext` elements do not read the same characters again. An
isolate that opens inside an element and closes after it hides the
rest of that element.
vectorcraft-svg takes `unicode-bidi` 0.3.18, which vectorcraft-text
already uses, for the bidi classes.
Place, Open and relink read a CMYK or grayscale TIFF with an alpha
channel through extra_samples_tiff_rgba, which cut every 16-bit sample
to its high byte before converting it. A faint ink or a low alpha was
lost: cyan 129 at full alpha showed as white, and an alpha of 129
became fully transparent.
The samples are now normalized at the depth the file stores them, and
only the resulting color and alpha are rounded to 8 bits (a 16-bit
alpha to the nearest 8-bit value). Associated alpha is divided out at
16 bits. A pixel whose associated alpha is zero now has no color,
instead of keeping its stored color. TIFF 6.0's Associated Alpha
Handling section states this arithmetic and the zero-alpha rule for
RGB data; applying them to CMYK and gray samples is VectorCraft's own
rule.
With Smart Guides on, a selection the Selection tool grabbed by one of
its anchors only landed that anchor on other anchors and centers, or
lined its bounds up. The anchor now also lands on the other objects'
paths ("path"), and where a path crosses another path or a ruler guide
("intersect"), in the order Direct Selection uses for a dragged anchor.
When the anchor lands on a path, the bounds do not also line up with
other objects, and a ruler guide nearby does not pull it off the path.
A selection grabbed anywhere else keeps lining its bounds up.
- Targets::for_move_by_anchor gathers the other art's path segments as
well, and Targets::snap_onto_path lands a point on them or on their
crossings with each other and with the ruler guides.
- MoveSnap::by_anchor uses those targets; the Selection tool picks it
when the press grabbed an anchor.
