Oh Wise Gurus!
I need to create single line vectors, "Not closed outline vectors" from a Jpeg file , I want to emulate hand engraving on soft metal. I don't need depth, I intend on using a drag bit to engrave the metal. I just can't figure out how to create the single line vectors without hand copying each and every line. The trace bitmap function outlines each line with a closed vector. Is there a gadget or some function to convert the lines to vectors? The example image is attached.
