Janome Embroidery Format JEF
The JEF and JEF+ files consists of a number of sections. Multi-byte numbers appear to be stored little endian. For the JEF (and not JEF+ ) files, there is no simple signature, except to see if the Stitch-offset is after the Thread-type-list. The JEF pattern can easily be extracted from JEF+ files; by using the Stitch-offset to the Stitch-list, to skip over the JEF+ header; and then to ignore the JEF+ details, after the Stitch-list, at the end of the file.
