Codepen: Circle + Chargement Crop
Codepen: Square + Init Url Crop
Codepen: Rectangle Crop
Codepen: Rectangle With Aspect Crop
Codepen: Rectangle + Aspect + Array Crop
-
If aspect ration is not setted and type is rectangle, make result-image-size have scale of crop area. As result image values will be takken number(will be width), {w: Number} and {h: Number}.
-
Add option to not resize cropper area on siders.
-
On aspect ration when height is more then width, crop area don't go down.
-
Add option to set fixed Height or Width of the crop area.
-
Wrap input(file) within plugin, so it don't have any load problems, like with angular material dialog. Make in it an area with a message inside to click for upload new file. This will be by option enabled. Rebuild all demo with this feature. Add button on work space to add new image if image given, make full options for that.
-
Add filters apply. Make an easy way to create new filters. Add some basic filters like Brightness,Contrast,Blur etc.

You have three options to get the files:
- Download ngImgCropExtended files from GitHub.
- Use Bower to download the files. Just run
bower install ngImgCropFullExtended. - 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. By default, to reduce CPU usage, when a user drags/resizes the crop area, the result image is only updated after the user stops dragging/resizing. Set true to always update the result image as the user drags/resizes the crop area.
Optional. Type of the crop area. Possible values: circle|square|rectangle. Default: circle.
Optional. Min. width/height of the crop area (in pixels). Default: 80.
Optional. Width/height of the result image (in pixels). Default: 200.
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).
Optional. Expression to evaluate upon changing the cropped part of the image. The cropped image data is available as $dataURI.
Optional. Expression to evaluate when the source image starts loading.
Optional. Expression to evaluate when the source image successfully loaded.
