Thread charts

Status

What it is

Thread chart files may carry color lists, thread order, or production notes beside sparse stitch streams such as DST or EXP.

Satin Studio behavior

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

Versions and variants

Thread chart sidecars vary widely by software and seller. CSV, TXT, and INF files should be interpreted only after the specific layout is recognized.

File identification notes

Usually text or simple structured data; varies by workflow.

Observed structure notes

• Thread sidecars may be CSV-like rows, INI/INF-style sections, simple line-oriented text, or vendor-specific color files.
• They should be imported as reviewable metadata and matched against stitch-stream color blocks, not treated as authoritative by extension alone.

Structure sketch

Thread-chart sidecars are text-like metadata until a specific layout is recognized.

enum ThreadChartSidecar<'a> {
    Csv { rows: &'a [CsvRow<'a>] },
    Text { lines: &'a [&'a str] },
    Inf { sections: &'a [InfSection<'a>] },
}

struct CsvRow<'a> {
    fields: &'a [&'a str],
}

struct InfSection<'a> {
    name: &'a str,
    key_values: &'a [(&'a str, &'a str)],
}

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.
