# Jimp ... in a browser #
|
||||
|
||||
Browser support for Jimp was added by Phil Seaton. This enabled Jimp to be used in [Electron](http://electron.atom.io/) applications as well as web browsers.
|
||||
|
||||
Example usage:
|
||||
|
||||
```html
|
||||
<script src="jimp.min.js"></script>
|
||||
<script>
|
||||
Jimp.read("lenna.png").then(function (lenna) {
|
||||
lenna.resize(256, 256) // resize
|
||||
.quality(60) // set JPEG quality
|
||||
.greyscale() // set greyscale
|
||||
.getBase64(Jimp.MIME_JPEG, function (err, src) {
|
||||
var img = document.createElement("img");
|
||||
img.setAttribute("src", src);
|
||||
document.body.appendChild(img);
|
||||
});
|
||||
}).catch(function (err) {
|
||||
console.error(err);
|
||||
});
|
||||
</script>
|
||||
```
|
||||
|
||||
See the [main documentation](https://github.com/oliver-moran/jimp) for the full API documenatinon.
|
||||
|
||||
## WebWorkers ##
|
||||
|
||||
For better performance, it recommended that Jimp methods are run on a separate thread using [`WebWorkers`](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers). The following shows how using two files (`index.html` and `jimp-worker.js`):
|
||||
|
||||
```js
|
||||
// index.html
|
||||
|
||||
var worker = new Worker("jimp-worker.js");
|
||||
worker.onmessage = function (e) {
|
||||
// append a new img element using the base 64 image
|
||||
var img = document.createElement("img");
|
||||
img.setAttribute("src", e.data);
|
||||
document.body.appendChild(img);
|
||||
};
|
||||
worker.postMessage("lenna.png"); // message the worker thread
|
||||
```
|
||||
|
||||
```js
|
||||
// jimp-worker.js
|
||||
|
||||
importScripts("jimp.min.js");
|
||||
|
||||
self.addEventListener("message", function(e) {
|
||||
Jimp.read(e.data).then(function (lenna) {
|
||||
lenna.resize(256, 256) // resize
|
||||
.quality(60) // set JPEG quality
|
||||
.greyscale() // set greyscale
|
||||
.getBase64(Jimp.MIME_JPEG, function (err, src) {
|
||||
self.postMessage(src); // message the main thread
|
||||
});
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## CDN ##
|
||||
|
||||
CDN access to the minified library is available through the [RawGit CDN](https://rawgit.com/):
|
||||
|
||||
```html
|
||||
<script src="https://cdn.rawgit.com/oliver-moran/jimp/v0.2.28/browser/lib/jimp.min.js"></script>
|
||||
```
|
||||
