libpes is a portable C library for encoding, decoding and transcoding the PES and SVG based machine embroidery formats. The PES format is amachine embroidery file format forBrother Industries andBernina International series of embroidery machines, among others. PES files contain sewing coordinates for stitches and corresponding thread colors.

• pes-info prints out internal PES data structures for a given PES file.
• pes-to-svg-emb converts a PES file to a correspondingSVG embroidery file.
• svg-emb-to-pes is the reverse ofpes-to-svg-emb and as such the conversion is limited to the SVG embroidery format as a subset of SVG generated bypes-to-svg-emb.

Check thePES format wiki.

libpes implements a prototype SVG embroidery format with the intention of being a vendor neutral format that is more convenient to display, generate and modify than PES or other proprietary formats. The idea more specifically is to represent machine embroidery instructions in the SVG format, as opposed to general rendering of SVG. As of this particular implementation onlypath elements are supported with mandatorystroke andd attributes, as shown in the example below.

examples/envelope.svg is an example of SVG embroidery. It contains a singlepath element with seven (x,y) coordinate pairs forming a shape of an envelope:

<?xml version="1.0"?><!DOCTYPEsvg PUBLIC "-//W3C//DTD SVG 1.1//EN"  "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"><svgwidth="8.0mm"height="5.0mm"version="1.1"viewBox="0.0 0.0 8.0 5.0"xmlns="http://www.w3.org/2000/svg">  <pathstroke="#000000"fill="none"stroke-width="0.4"d="M 8.0 0.0 L 0.0 0.0 L 0.0 5.0 L 8.0 5.0           L 8.0 0.0 L 4.0 2.0 L 0.0 0.0" /></svg>
