Hi STEFAN.

Thanks a lot for sharing!

Very interesting for Mac users.

If you want to remain within Moi without using any external tool you can use the great Max's "HeightMap" commands!

It generates curves (or point) from an input b&w or greyscale image.

Although the resulting curves needs to be a tweaked a little bit with the "rebuild" command to make them "lighter" ,
before export them to PDF, for importing into Affinity Designer or any other vector graphic software.

You can get the Max's command here : http://take.ms/e2vSN
N.B. In windows you need to run Moi in Administrator mode in order to make HeightMap works.

This is a brief video I made : http://take.ms/fVOE0
