npm install @magenta/imageThis JavaScript implementation of Magenta's image models uses TensorFlow.js for GPU-accelerated inference.
Complete documentation is available at https://tensorflow.github.io/magenta-js/image.

- Getting Started
You can try our hosted demos for each model and have a look at the demo code.
Implements Ghiasi et al.'s fast arbitrary style transfer model (paper, code). Wraps around Reiichiro Nakano's TensorFlow.js port of the model checkpoint.
There are two main ways to get MagentaImage.js in your JavaScript project:
via script tags or by installing it from NPM
and using a build tool like yarn.
Add the following code to an HTML file, and place a content (content.jpg) and style (style.jpg) image in the same directory:
``html`


Launch a simple HTTP server (e.g. python3 -m http.server) and point your browser to http://0.0.0.0:8000/. You should see your content and style images displayed and, after a few seconds, the stylized output.
Add [MagentaImage.js][mi-npm] to your project using yarn or npm.
For example, with yarn you can simply call yarn add @magenta/image.
Then, you can use the library in your own code as in the following example:
`js
import * as mi from '@magenta/image';
const model = new mi.ArbitraryStyleTransferNetwork();
const contentImg = document.getElementById('content') as HTMLImageElement;
const styleImg = document.getElementById('style') as HTMLImageElement;
const stylizedCanvas = document.getElementById('stylized') as HTMLCanvasElement;
function stylize() {
model.stylize(contentImg, styleImg).then((imageData) => {
stylizedCanvas.getContext('2d').putImageData(imageData, 0, 0);
});
}
model.initialize().then(stylize);
`
See style-transfer.glitch.me and our demos for example usage.
