dotCooCoo 060e968246 Image Trace: keepColors traces only the listed palette colors ...

Image Trace had no way to trace some of an image's colors and leave the
rest out. Ignore Color drops one color, so tracing only the line work of
a multi-color image took a full trace and then deleting the other
colors' paths by hand.

With "keepColors": ["#rrggbb", ...] in the params of imageTrace.make and
imageTrace.makeAndExpand, only the palette colors within about 30 levels
of a listed color are traced, the distance Ignore Color matches by. With
Method Abutting, the kept colors' paths are the same as in a trace of
every color. With Method Overlapping, a kept color's paths do not reach
under the colors left out, as with Ignore Color. An empty list traces
every color, and a value that is not a six-digit hex color is refused.
Flat Logo mode does not use the list.

The reply's warnings name each listed color that matches none of the
colors the trace found, and say when nothing was traced; the status bar
shows the first. The warnings are translated in every complete catalog.
The params help of imageTrace.make lists keepColors and the new
warnings, and the help of imageTrace.makeAndExpand lists the warnings
it returns.
