The Tajima Embroidery Stitch (DST) format is a coordinate-based design file developed by Tajima Industries for controlling automated embroidery machinery. It functions as an industry standard for commercial textile manufacturing, containing low-level commands for needle movements, jumps, and thread trims. This legacy format remains universally compatible with professional embroidery software and is considered safe for processing because it lacks executable code or complex scripting capabilities.

Validation Code

How to validate .dst files in Python

Python
def is_dst(file_path: str) -> bool:
    """Check if file is a valid DST by magic bytes."""
    signature = bytes([0x44, 0x56, 0x44])
    with open(file_path, "rb") as f:
        return f.read(3) == signature

How to validate .dst files in Node.js

Node.js
function isDST(buffer: Buffer): boolean {
  const signature = Buffer.from([0x44, 0x56, 0x44]);
  return buffer.subarray(0, 3).equals(signature);
}
Go
func IsDST(data []byte) bool {
    signature := []byte{0x44, 0x56, 0x44}
    if len(data) < 3 {
        return false
    }
    return bytes.Equal(data[:3], signature)
}
