Like bright red or black or dark blue? I'd have to have one of those things, and play with it for a bit, to be sure. Oh, or maybe if the pattern was a darker color, that might work too. I'm not positive that would work, but it might. Then possibly Trace Bitmap could be configured to be able to "see it" well enough to create a proper path. Maybe if you could take a marker, a heavy marker, and trace over the line before you scan it in (or however you achieved the image, I'm not sure) (or maybe it's a photo?). I don't know of any trace engine which can pick out the cutting line from your image. But if you want to send them a cuttable file, you'll need to trace the pattern by hand (using Pen tool in Inkscape). I mean, you could simply scan the pattern pieces into your computer, and send them separately (in a multi-page PDF) and they could do whatever they want with them. What do you want others to be able to do with the PDF? Do you want them to be able to cut out whatever you send them? Or do you just want to send them the pattern, and they can do whatever they want with it? So as I said earlier, tracing by hand using the Pen tool, would be the best approach for that kind of image. The kind of image which can give the best trace result would be a heavy, solid, black line on a solid white or solid colored background. The attachment shows my result from tracing with the Grays option. The problem is that Inkscape traces exactly what it "sees". But 2nd, the reason you could see something in the preview window, is because that option looks only at shades of gray, which is what your image is made of.

When you switched to the Grays button, it did 2 things. Inkscape's "eye" can't figure it out.Ĭhanging the file name did not have anything to do with it. Because your human eye can make out the proper outline. The best approach for tracing that image is to trace it by hand, with the Pen tool. The problem is that your original image is not really in the kind of condition where you can achieve a good trace, using auto trace. So in your 2nd screenshot, where the pattern pieces are on the right, and there is the solid line on the left, did you trace that with the Pen tool?
