stitch-peek-rs

A Nautilus/GNOME thumbnailer for embroidery files. Browse your embroidery designs in the file manager with automatic thumbnail previews.

Supported formats: PES, DST, EXP, JEF, VP3

Built as two crates:

Crate	Description
rustitch	Library for parsing embroidery files and rendering stitch data to images
stitch-peek	CLI thumbnailer that integrates with GNOME/Nautilus

Installation

From .deb (Debian/Ubuntu)

Download the latest .deb from the Releases page:

sudo dpkg -i stitch-peek_*_amd64.deb

This installs the binary, thumbnailer entry, and MIME type definition. Restart Nautilus to pick up the changes:

nautilus -q

From crates.io

cargo install stitch-peek

Then install the data files:

sudo install -Dm644 data/stitch-peek.thumbnailer /usr/share/thumbnailers/stitch-peek.thumbnailer
sudo install -Dm644 data/pes.xml /usr/share/mime/packages/pes.xml
sudo update-mime-database /usr/share/mime
nautilus -q

From source

Requires Rust 1.85+.

git clone https://git.narl.io/nvrl/stitch-peek-rs.git
cd stitch-peek-rs
cargo build --release

sudo install -Dm755 target/release/stitch-peek /usr/local/bin/stitch-peek
sudo install -Dm644 data/stitch-peek.thumbnailer /usr/share/thumbnailers/stitch-peek.thumbnailer
sudo install -Dm644 data/pes.xml /usr/share/mime/packages/pes.xml
sudo update-mime-database /usr/share/mime
nautilus -q

Usage

As a thumbnailer

Once installed, Nautilus will automatically generate thumbnails for embroidery files. No manual action needed -- just open a folder containing .pes, .dst, .exp, .jef, or .vp3 files.

Standalone CLI

Generate a thumbnail manually:

stitch-peek -i design.pes -o preview.png -s 256
stitch-peek -i pattern.dst -o preview.png -s 256

Flag	Description	Default
-i	Input embroidery file	required
-o	Output PNG path	required
-s	Thumbnail size (pixels)	128

As a library

Add rustitch to your project:

[dependencies]
rustitch = "0.1"

// PES (auto-detected)
let pes_data = std::fs::read("design.pes")?;
let png_bytes = rustitch::thumbnail(&pes_data, 256)?;

// Any supported format (explicit)
let dst_data = std::fs::read("pattern.dst")?;
let png_bytes = rustitch::thumbnail_format(&dst_data, 256, rustitch::Format::Dst)?;

See the rustitch README for more API examples.

Supported formats

Format	Manufacturer	Colors	Notes
PES	Brother PE-Design	Embedded (PEC palette)	Versions 1-10
DST	Tajima	Default palette	3-byte bit-packed records
EXP	Melco/Bernina	Default palette	Simple 2-byte encoding
JEF	Janome	Embedded (Janome palette)	Structured header with color table
VP3	Pfaff/Viking	Embedded (RGB)	Hierarchical format with per-section colors

Development

cargo test          # run all tests
cargo clippy        # lint
cargo fmt --check   # check formatting

Pull requests must bump the version in stitch-peek/Cargo.toml -- CI will reject merges without a version bump.
