That image should work, but you may have to enlarge it in Gimp first, and
give it more white space (increase canvas size).
The final stack that handles color is pretty awesome. Here's that final
post in the thread:

Hi,
Color Tracing, Color Tracking.
here is a version of an image tracing stack that traces color images.
It makes a graphic for each color. And it makes a combined graphic from the
color-subgraphics.
You have quite some options which graphics to include.
note that this stack has a button with a question mark in it with some
instruction how to use it.
The main stack has three substacks. Makes for some clutter but accomodates
larger images.
Please choose a posterization level after loading an image.
Only if the image turns completely black on posterization reload the image
and "Color Trace" it without posterization.
Due to the tricky nature of images/colors you may not get satisfactory
results with all images. Especially subtle gradients are hard to get at a
reasonable resolution.
There is also a substack to use Livecode's Paint Tools to paint simple
forms and convert them into graphics.
Please choose a posterization level before "color tracing".
You can download the stack here:

Comments welcome.
Dear Bernd, I tried with this image:
https://www.dropbox.com/sh/ja47l87gg87sn0q/AAAIj99kEQVOb8ev3jz8C5ORa?dl=0 file:
Hturtle.png
which was set in GIMP to grayscale. On tracing I got a message about it
containing more than 12 colours; so it did not trace.

What to do with the graphics is anybodys guess. But it was fun to do. I
would be interested in real world use cases.
Kind regards
Bernd

That stack is super . . . But . . .
I have an image with discontinuous black bits:
https://www.dropbox.com/sh/ja47l87gg87sn0q/AAAIj99kEQVOb8ev3jz8C5ORa?dl=0
seaTurtle.png
which I would like to convert into a SINGLE graphic, and am beginning to
suspect is not possible.

1. Trace an image in a stack to get a vector graphic?
I shall be doing that outwith Livecode using Inkscape.
2. Has the Kickstarter goal of importing vector graphics been arrived at
yet?
I shall use Alejandro Tejada's EPS importer:

2.1. And if so, how come I missed that?
Richmond.
