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-detail}

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

27+N5+N6 N7 Record Stitches

- 27+N5+N6+N7

1 Byte unknown = 0

Colour-detail

Offset Length Type Description
0 3 RRGGBB Colour-RGB
3 1 Byte unknown = 0 or 10
4 1 Byte unknown = 0 5 1 Byte unknown = 0, 20, or 10

Thread-text

Offset Length Type Description
