Update: I made an executable called "hair" which takes two filenames as command line arguments ($outline.svgd and $path.svgd). The contents are read by read_svgd, I usually just copy the content from a SVG file. The stitches are computed and the result is written in $outline.svgd.svg / $outline.svgd.txt. The .txt file can be converted to many different embroidery formats by libembroider-convert: https://github.com/Embroidermodder/Embroidermodder I applied the method to mane and tail of this vector: http://imageconstructor.deviantart.com/art/Luna-545158121 Here you can see the results (input paths and embroidered versions): http://imgur.com/a/bRrko http://imgur.com/a/LVs8j http://imgur.com/a/d0sc1 I tried to make the stitches follow the direction of the hairs. One problem is that Inkscape::half_outline sometimes increases the number of nodes which leads to exponential node count increase when applied repeatedly: http://imgur.com/a/doJaU Is there an alternative? If not I might have to write one.
