Viking/Husqvarna Pfaff/Singer 3 VP3
The VP3 file format appears to be series of nested sections. Most sections contain tagged records.
In the style of Backus–Naur Form,
File = File-header Extent
Extent = Extent-header {Hoop}
Hoop = Hoop-header Canvas Threads
Threads = Threads-header {Thread}
Thread = Thread-header Colours Thread-text Thread-detail Stitches Thread-end
Colours = {Colour}
Stitches = Stitches-header {Stitch}
File-header
| Offset | Length | Type | Description |
| 0 | 6 | ASCIIZ | Signature = "%vsn%" |
| 6 | N1 | N-WStr | Producer 16 bit big-endian length in bytes followed by 16 bit characters |
| 6+N1 |
This file format appears to describe a stitch out similar to that used in JEF files.
