Efficient, Lossless, and Secure

ESKEES is a desktop application that assembles parts from PSD files or illustrations and exports them as EMG—an open format that treats the assembly as a single texture. It offers a solution useful for loop animations and asset management. AlphaChannel Supprted.

In development. If you would like to take part in the test, apply below.

Product

ESKEES Editor Coming soon
Assemble parts from PSD / KRA / images / animated GIF / sprite sheets, add blink, lip sync and motion, and export .emg. A Windows desktop app.
ESKEES Screen Test build
Use motion backgrounds on your PC desktop.
CDN Available
A player that renders .emg in the browser. Works with two script tags.
Viewer Available
Open a .emg in the browser and inspect its parts, layers and atlas. Just drag your own file in.
Importer Available
Implementations that bring .emg into Unity, Godot, Ren'Py and YMM4. All published under Apache 2.0.

ESKEES Screen

Runs the .emg you exported as a Windows desktop wallpaper. No other software needed.

Nothing else to install
It draws with the OS WebView, so no browser is bundled.
Driven from the tray
Switch the file on show, how it fits the screen, the render resolution and the backdrop colour.
Fits any screen
Crop to fill, fit whole, or stretch.
Eco Mode
It stops animating while covered by other windows, and on battery or in power-saver mode.

Windows 10 / 11. It renders with WebView2, which ships with Windows 11.
Scheduled Releases for macOS Versions.
A test build is available. If it does not work, send us eskees-screen.log from next to the executable.

Use it from a CDN

Two script tags and a URL. No build step, no bundler.

<div id="layerContainer"></div>

<!-- JSZip（必須依存。.emg は ZIP なので展開に要る） -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.7.1/jszip.min.js"></script>

<!-- EMG Player -->
<script src="https://pxrllc.github.io/emg/emg-player.0.3.0.js"></script>

<script>
  EMGPlayer.loadEmgFromCDN('https://example.com/avatar.emg');
</script>

JSZip is required. A .emg is a ZIP, so it is needed to unpack it. Load it first.
It renders into #layerContainer by default. For another element, pass loadEmgFromCDN(url, 'myContainer').
The result arrives on window as emg:loaded / emg:error.
The .emg may live on another origin, but it must allow CORS — it is fetched.

Drive it from the host

`EMGPlayer.setFrame(partID, frame)`	Pick the visible frame of a switch part
`EMGPlayer.showPart(partID, shown)`	Show or hide a part
`EMGPlayer.setPartPlaying(partID, playing)`	Stop or resume a part
`EMGPlayer.setBlinkState(state)`	Blink (requires mapping.json)
`EMGPlayer.setViseme(v)`	Lip sync (same)
`EMGPlayer.setExpression(name)`	Expression (same)
`EMGPlayer.setPreset(id)`	Switch several parts at once (0.5.0 §5)

It is currently served from the public repository's GitHub Pages. If it moves under eskees.com, the versioned URLs will be kept.

Every field, with the version that introduced it and where it is specified.
