EXP — Melco

EXP is the "minimal standard" Melco format: a stream of 2 signed bytes per stitch (dx, dy), with 0x80 as the special-command marker. No colors, no hoop, no magic bytes.

What it supports and what it does NOT

• Colors: absent. You pick them on the machine.
• Hoop: absent. Same story.
• Trims: yes, via the 0x80 0x80 0x07 control sequence (the reader maps it back to TRIM). With "Remove trims" the rewritten file stays trim-free.
• Color change: special marker.

UI notes

EXP does not store colors: you pick them on the machine.

Detection

No reliable magic bytes (EXP simply has no magic at all), so registry.ts resolves it by extension. Reading is permissive: when a file is unreadable, the other formats get a fallback by extension.
