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 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.

== SEW Format ==
 +
This appears to be an earlier format, it is fairly simple (from the examples seen), it includes bitmap previews, but sometimes they do not match the pattern described in stitches. The format seems to use the same thread colour codes and the same stitch-list as JEF.
 +
 +
Format appears to be little endian, except for the bitmaps.

=== Bitmap ===
 +
The bitmaps and sets of bitmaps appear to start at several fixed file offsets:<br/>
 +
0x004A 1 x 48 pixel by 32 lines monochrome<br/>
 +
0x010C 1 to 12 x 24 by 16, one for each colour<br/>
 +
0x043C 1 x 64 by 48 monochrome<br/>
 +
0x05BE 1 to 12 x 64 by 48, one for each colour<br/>
 +
0x17D6 1 x w x h, variously sized monochrome outline and centre mark.<br/>
 +
There are about 1440 bytes before the stitch-list.
 +
 +
This last bitmap may give an indication of the size in millimetres, the width will be a multiple of 8&nbsp;mm. The available bits (for pixels or mm) 1440 x 8 = 11,520 gives a maximum size around 120&nbsp;mm x 96&nbsp;mm, so may be not.

The bitmap is similar to PBM P4 format, a PBM file can be created by writing:<br/>

  "P4\n"

  "%d %d\n", Width * 8, Height

then copy Width x Height chars

The SEW stitches appear to start at the fixed file offset 0x1D78, and use the same Escaped-command and (8 bit, 8 bit) Displacement as JEF above.

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.

File = File-header Thread-colour-list Thread-type-list [Plus-header] Stitch-list {Plus-detail}

Thread-type

Offset Length Type Description
0 4 int unknown = 13

Plus-header

Only in JEF+ files.

Offset Length Type Description
0 4 int Signature-1 = 0
4 4 int Signature-2 = 0
8 8 ASCII Signature-3 = "JANOME\0\0"
16 4 Count Plus-detail-count = 1
20 4 Offset Plus-detail-offset from file-start to JEF+ extra details

Escaped-command

Offset Length Type Description
0 1 Byte Escape = -128 or 0x80
1 1 Byte Command-code = 1, 2 or 16


Command-code Description
1 Change to next thread in list
2 Move followed by 8 bit displacement-X and 8 bit displacement-Y
16 Last-stitch

Displacement

Offset Length Type Description
0 1 Byte Displacement-X -127 to 127 in 0.1 mm
1 1 Byte Displacement-Y -127 to 127 in 0.1 mm


Plus-detail

Unknown, many 32 bit numbers, then many 16 bit numbers.


SEW Format

This appears to be an earlier format, it is fairly simple (from the examples seen), it includes bitmap previews, but sometimes they do not match the pattern described in stitches. The format seems to use the same thread colour codes and the same stitch-list as JEF.

Format appears to be little endian, except for the bitmaps.

SEW-file = SEW-header {Bitmap} {stitch}

SEW-header

Only SEW files

Offset Length Type Description
0 2 Count Colour count; maximum of 12 colours
2 12x2 Table Colour index table padded with 0; JEF colour code
0x1A 12x2 Table Colour unknown; all entries appear to have the same value: 8 or 0 or 255
0x32 12x2 Table Stitches per colour (minus a few)
0x4A


Bitmap

The bitmaps and sets of bitmaps appear to start at several fixed file offsets:
0x004A 1 x 48 pixel by 32 lines monochrome
0x010C 1 to 12 x 24 by 16, one for each colour
0x043C 1 x 64 by 48 monochrome
0x05BE 1 to 12 x 64 by 48, one for each colour
0x17D6 1 x w x h, variously sized monochrome outline and centre mark.
There are about 1440 bytes before the stitch-list.

This last bitmap may give an indication of the size in millimetres, the width will be a multiple of 8 mm. The available bits (for pixels or mm) 1440 x 8 = 11,520 gives a maximum size around 120 mm x 96 mm, so may be not.


Offset Length Type Description
0 1 Count Width of bitmap in (8 bit) bytes
1 1 Count Height of bitmap in lines/rows
2 Width x Height Byte Bits from top to bottom, left to right, MSB to LSB
2 + Width x Height


The bitmap is similar to PBM P4 format, a PBM file can be created by writing:

 "P4\n"
 "%d %d\n", Width * 8, Height

then copy Width x Height chars

Stitch

The SEW stitches appear to start at the fixed file offset 0x1D78, and use the same Escaped-command and (8 bit, 8 bit) Displacement as JEF above.
