You have four options to get the files:
- Download ngImgCropExtended files from GitHub.
- Use Bower to download the files. Just run
bower install ngImgCropFullExtended. - Use Npm to download the files. Just run
npm i ng-img-crop-full-extended. - Use Meteor to download the files. Just run
meteor add correpw:ng-img-crop-full-extended.
Add the scripts to your application. Make sure the ng-img-crop.js file is inserted after the angular.js library:
<script src="angular.js"></script>
<script src="ng-img-crop.js"></script>
<link rel="stylesheet" type="text/css" href="ng-img-crop.css">Add the image crop module as a dependancy to your application module:
var myAppModule = angular.module('MyApp', ['ngImgCrop']);- Add the image crop directive
<img-crop>to the HTML file where you want to use an image crop control. Note: a container, you place the directive to, should have some pre-defined size (absolute or relative to its parent). That's required, because the image crop control fits the size of its container. - Bind the directive to a source image property (using image="" option). The directive will read the image data from that property and watch for updates. The property can be a url to an image, or a data uri.
- Bind the directive to a result image property (using result-image="" option). On each update, the directive will put the content of the crop area to that property in the data uri format.
- Set up the options that make sense to your application.
- Done!
The result image will always be a square for the both circle and square area types. It's highly recommended to store the image as a square on your back-end, because this will enable you to easily update your pics later, if you decide to implement some design changes. Showing a square image as a circle on the front-end is not a problem - it is as easy as adding a border-radius style for that image in a css.
- Notice for mobile device: Using Data URI is very slow on mobile device, 6x slower. (http://www.mobify.com/blog/data-uris-are-slow-on-mobile/) Use instead blobUrl.
The following code enables to select an image using a file input and crop it. The cropped image data is inserted into img each time the crop area updates.

- Notice for mobile device: Using Data URI is very slow on mobile device, 6x slower. (http://www.mobify.com/blog/data-uris-are-slow-on-mobile/) Provide instead a blob.
Assignable angular expression to data-bind to. NgImgCrop puts a data uri of a cropped image into it.

Optional. Min. width/height of the crop area (in pixels). Default: 80.
Optional. Width/height of the result image (in pixels). Default: 200. 'selection' renders an image of the size of the area selected. 'max' maximizes the rendered image.
While you have added an array inside of option result-image-size you will have option to get array of dataURI alogside with width and height requested.
Optional. Format of result image. Possible values include image/jpeg, image/png, and image/webp. Browser support varies. Default: image/png.
Optional. Quality of result image. Possible values between 0.0 and 1.0 inclusive. Default: browser default.

Optional. Provide dominant color for image using color-thief (https://github.com/lokesh/color-thief).
Optional. Provide a color palette for image using color-thief (https://github.com/lokesh/color-thief).
Optional. Provide a color palette for image using color-thief (https://github.com/lokesh/color-thief).
