With Document Swatches as the library, traced fills and strokes take the
library color without a swatch link. Global, spot and tint swatches no
longer link the trace, so editing a swatch later leaves the trace
unchanged, and swatch order no longer decides whether a fill is linked.
Each region still takes the nearest library color, and a tint traces at
the color the tint swatch shows.
Each traced path filtered the whole library for its color, twice when
no swatch of that color was linked. The color-to-paint lookup is now
built once before the paths are filled. The first linked swatch of a
color still gives the fill, and the first swatch of that color
otherwise.
When a process swatch listed before a global or spot swatch showed the
same color, a traced fill of that color took the process swatch and
stayed unlinked. Of the swatches that trace as one color, the first
linked one now gives the fill, and the first one otherwise.
From the review of #4605. TraceParams::swatches isn't in the settings' JSON (serde skip), so a Document Library trace whose swatches were edited while it ran still applied, with the old colours; the trace's inputs now hold them. The 100 ms repaint that keeps background work moving left traces out, so without input a finished trace could wait for the next event.
Tracing a photo or a large image ran inside imageTrace.make on the UI
thread, so the window froze for as long as the trace took, with nothing
to say it was working.
A trace the user asks for (Object > Image Trace > Make and Make and
Expand, the task bar's Image Trace, the Image Trace panel's Trace and
presets) now runs on a thread of its own, as heavy plug-in filters do.
The status bar says so, and after 0.4 s a progress window shows how
many of the image's colors are traced, with Cancel and Continue in
Background (imageTrace.cancelRuns, imageTrace.hideRuns).
The result goes back to the command it was prepared for
(cmd::TraceRun, Traced::hand_in), which takes it only for the same
object, image and settings, so the edit is one undo step as before. A
newer trace of the same object replaces one still running, and a trace
whose image or settings changed meanwhile changes nothing. The control
channel, MCP, scripts and the web trace at once, as before.
The tracer reports its stages and color layers to a callback and stops
when it says so (trace_watched).
