OFM

Status

What it is

OFM is a Melco DesignShop working file for editable embroidery designs.

Satin Studio behavior

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

Versions and variants

OFM is a native working format. It should not be treated as a simple expanded stitch stream without version-specific evidence.

File identification notes

Reported OFM-family files are compound binary documents and may include stitch data among richer design/application data.

Observed structure notes

• OFM is a native Melco working-file lead. Treat it as a compound/application document until version and stream maps are verified.
• Expect richer design objects, settings, and generated stitch data rather than a single expanded stream.

struct OfmStream<'a> {
    name_or_kind: Option<&'a str>,
    payload: &'a [u8],
}
