ImageEdit Angular Module

Use an image, edit it to fit inside a specific size, that you can use to upload wherever and however you want

Install

Copy the angular-image-edit.js and angular-image-edi.css files into your project and add the following line with the correct path:

	<script src="/path/to/scripts/angular-image-edit.js"></script>
	<link rel="stylesheet" href="/path/to/scripts/angular-image-edit.css">

Alternatively, if you're using bower, you can add this to your component.json (or bower.json):

	"angular-image-edit": "~0.2.0"

Or simply run

	bower install angular-image-edit

Check the dependencies to your html (unless you're using wiredep):

	<script src="components/angular/angular.js"></script>

And (unless you're using wiredep):

	<script src="components/angular-image-edit/dist/angular-image-edit.js"></script>

And the css:

	<link rel="stylesheet" href="components/angular-image-edit/dist/angular-image-edit.css">

Add the module to your application

	angular.module("myApp", ["ImageEdit"])

Usage

	</cropme>
    <image-edit
        width="250"
        height="250"
        src="src"
        zoom="zoom"
        type="png">
    </image-edit>

Attributes

type (optional)

Valid values are 'png' or 'jpeg' (might work with webm too, haven't tried it)

width (optional)

Set the target (cropped) picture width (default 300). width="250" the cropped image will have a width of 250px.

height (optional)

Set the target (cropped) picture height (default 300). height="250" the cropped image will have a height of 250px.

src

url of the image to edit. IT should be an angular module. Can contain an data: URL.

zoom (optional). (default 0)

Percentage of zooming between 0 and 100. It can be an angular model or an integer.

Events Sent

The blob will be sent through an event, to catch it inside your app, you can do it like this:

	$scope.$on("ImageEdit:done", function(ev, result) { /* do something */ });

Where result is an object with the following keys:

	blob: edited image as a blob
	uri: edited image as data URL

Also ImageEdit will send an event when a picture set by the user, so you can do something like

	$scope.$on("ImageEdit:loaded", function(ev, width, height) { /* do something when the image is loaded */ });
	$scope.$on("ImageEdit:loadFail", function(ev) { /* do something when the image could not load properly (maybe the src wasn't an url) */ });

Events Received

And you can trigger the edition by broadcasting the event ImageEdit:edit, for example:

	$scope.$broadcast("ImageEdit:edit");

So, now, how do I send this image to my server?

	scope.$on("ImageEdit:edit", function(ev, result) {
		var xhr = new XMLHttpRequest;
		xhr.setRequestHeader("Content-Type", result.blob.type);
		xhr.onreadystatechange = function(e) {
			if (this.readyState === 4 && this.status === 200) {
				return console.log("done");
			} else if (this.readyState === 4 && this.status !== 200) {
				return console.log("failed");
			}
		};
		xhr.open("POST", url, true);
		xhr.send(result.blob);
	});
