Spx files are Pfaff machine binary stitch files.
All files start with magic numbers 25 73 70 78 25 (%spx%).
01 01 01 ---
Section tag 01 01 01. 08-0B Following that we have the remaining number of bytes in the file, in a 4 byte big endian number.
We then have in the 01 01 01 block 0x50 characters that typically read:
- 00 4E 00 20 00 20 00 20 00 20 00 20 00 20 00 20
- 00 20 00 20 00 20 00 20 00 20 00 20 00 20 00 20

Section tag 07 01 01.
5F-62 Following that we have the remaining bytes in the file, in a 4 byte big endian number.
We then have 0x2A character of:
- 00 01 06 01 01 00 00 00 6D 01 03 E8 00 00 07 01
- 00 01 00 01 00 00 00 00 19 00 00 00 00 00 00 00
- 00 00 00 00 00 00 00 00 00 00
- 8C-8F Then a we have the width in micrometers. So 5000 (dec) for a 5mm, and 49900 for a 49.9mm wide design.
- 90-92 This is followed by a 4 byte big endian number which is twice the width.
Followed by some unchanging data:
- 03 00 00 01 F4 00 00 0F A0 00 00 2E E0 00 00 8C
- A0 00 00 01 F4 00 00 03 E8 00 00 07 D0 00 00 00
- 00
- B4-B7 This is followed by the height in a 4 byte big endian number.
Then we have another bunch of unchanging characters:
- 00 00 EA 60 03 00 00 00 00 00 00 0B B8 00 00 17
- 70 00 00 23 28 00 00 00 FA 00 00 01 F4 00 00 03
- E8 01 05 01 01 00 00 00 1E 00 00 00 00 00 00 00
- 00 00 00 00 00 00 00 00 00 19
- F2-F5 Then the width again in 4 byte big endian.
- F6-F9 Then the height again in 4 byte big endian.
And we finish out the section with:
- 00 00 00 00 00 01
03 01 01 --- Section starts exactly at 0x100
103-106: Following that we have the remaining bytes in the file, in a 4 byte big endian number.
We 4 4-byte big endian numbers conveying some information about size.

We then enter section 02 01 01:
- Following that we have the remaining bytes in the file, in a 4 byte big endian number.
This is the stitches section:
- All stitches are grouped into 9 bytes. The first two bytes is always 80 2F and the last two are always 80 0F.
- 80 2F XX XX YY YY CC 80 0F
- XX XX is 2 bytes of little-endian signed relative coordinate.
- YY YY is 2 bytes of little-endian signed relative coordinate.
- CC is usually 00, F6 and 0A are also frequently seen values.
