I’m trying to trace some images to get the outline of the details instead of a full engraving. However, as you can see in the attached image the shadowing really throws a wrench in the works. I’ve tried half a dozen different programs to no avail. Would really appreciate any potential solutions as I’m beginning to think the trace will have to be done manually.
You may be correct about the manual aspect. Unless you consider the option to create a greyscale bitmap and engrave in that manner, you’d have to determine each area of color manually in order to get something resembling your objective. I’ve approached a similar image, a family coat-of-arms and threw in the towel, as it was far too complex to simplify to a vector image.
Additionally, I have found that complex designs with shading might require doing a few versions of image trace to build a composite or stack of shapes, each capturing a different part of the art.
