INB

Status

What it is

INB is reported for Inbro-related embroidery workflows in converter ecosystems.

Satin Studio behavior

Satin Studio documents this format for identification and inspection. It does not open or export the file.

Versions and variants

Tracked as a format lead until files confirm machine family, header layout, and command mapping.

File identification notes

Reported structure includes a large 8192-byte header followed by unsigned x, y, control-style records.

Observed structure notes

• Observed INB readers skip an 8192-byte (0x2000) header before the stitch stream.
• Observed records are three bytes: X, Y, control. Control bit 0x40 negates X and bit 0x20 negates Y after Y inversion.
• Observed low-nibble controls include 0x0 stitch, 0x1 color change with movement, 0x2 jump, and full control 0x04 end.

Structure sketch

Observed INB files use a large header and three-byte records:

struct InbCandidate<'a> {
    header: [u8; 0x2000],
    records: &'a [InbRecord],
}

struct InbRecord {
    x: u8,
    y: u8,
    control: u8,                       // 0x40 negates x; 0x20 negates y
}

enum InbCommand {
    Stitch,                            // control & 0x0F == 0x00
    ColorChange,                       // control & 0x0F == 0x01
    Jump,                              // control & 0x0F == 0x02
    End,                               // control == 0x04
}

Compatibility evidence

The notes above help identify and inspect the format; they do not imply import or export support. Keep the original file and record the machine and software that produced it.
