Link your Angular configurable file in this code.

<script src="~/App/App.module.js"></script>
 
<script src="~/App/App.config.js"></script>
 
<script src="~/App/CIController.js"></script>

Angular Module

You will need to include the module as a dependency of your application.

var uiroute = angular .module('uiroute', ['ui.router','ngImgCrop']);

Work in Angular Image Crop

This tree control will work when you use the < img-crop > directive as HTML attributes.

<img-crop image="myImage"
 
                                  result-image="myCroppedImage"
 
                                  area-type="{{imgcropType}}">
 
                        </img-crop>

Using Bootstrap Filestyle directive:

<input id="fileInput" filestyle=""
 
type="file" data-class-button="btn btn-default"
 
data-class-input="form-control"
 
data-button-text="Upload"  class="form-control" />

HTML Code

<div ng-controller="CIController " class="container-fluid">
 
    <div class="row">
 
        <div class="col-md-3">
 
            <div class="panel">
 
                <div class="panel-heading no-shadow">
 
                    <a href="" ng-click="reset()" class="pull-right">
 
                        <small class="fa fa-refresh text-muted"></small>
 
                    </a>Select an image file
 
                </div>
 
                <div class="panel-body">
 
                    <div class="form-group">
 
                        <input id="fileInput" filestyle="" type="file" data-class-button="btn btn-default" data-class-input="form-control" data-button-text="Upload"  class="form-control" />
 
                    </div>
 
                    <p class="pv">Crop type:</p>
 
                    <div class="btn-group btn-group-justified mb">
 
                        <label ng-click="imgcropTypes('square')"  class="btn btn-default">Square</label>
 
                        <label ng-click="imgcropTypes('circle')"  class="btn btn-default">Circle</label>
 
                    </div>
 
                    <br />
 
                    <div data-text="Cropped Image" class="imgcrop-preview">
 
                        <img ng-src="{{myCroppedImage}}" />
 
                    </div>
 
                </div>
 
            </div>
 
        </div>
 
        <div class="col-md-9">
 
            <div class="panel">
 
                <div class="panel-body">
 
                    <div class="imgcrop-area">
 
                        <img-crop image="myImage"
 
                                  result-image="myCroppedImage"
 
                                  area-type="{{imgcropType}}">
 
                        </img-crop>
 
                    </div>
 
                </div>
 
            </div>
 
        </div>
 
    </div>
 
</div>

CSS Code

Set the style in the image crop area design.

.imgcrop-area {
 
    width: 100%;
 
    height: 410px;
 
    overflow: hidden;
 
    background: #e6e9ee;
 
}
 
.imgcrop-preview {
 
    position: relative;
 
    width: 100%;
 
    height: 200px;
 
    margin: 0 auto;
 
    background: #e6e9ee;
 
    text-align: center;
 
}
 
    .imgcrop-preview:after {
 
        content: attr(data-text);
 
        display: block;
 
        position: absolute;
 
        height: 50%;
 
        text-align: center;
 
        margin: auto;
 
        top: 0;
 
        left: 0;
 
        bottom: 0;
 
        right: 0;
 
        z-index: 0;
 
        color: #8394a9;
 
    }
 
    .imgcrop-preview > img {
 
        position: relative;
 
        z-index: 1;
 
        max-width: 100%;
 
    }

Angular Controller

Initiate the crop area as “circle.”

$scope.reset = function () {
 
            $scope.myImage = '';
 
            $scope.myCroppedImage = '';
 
            $scope.imgcropType = 'circle';
 
        };
 
        $scope.imgcropTypes = function (mode)
 
        {
 
            $scope.imgcropType = mode;
 
        }

Angular Directive

You can use Bootstrap Filestyle as an Angular directive. When you will select the image using filestyle, set the element to the <img-crop> directive.

.directive('filestyle', filestyle);
 
    functionfilestyle () {
 
        controller.$inject = ['$scope', '$element'];
 
        return {
 
            restrict: 'A',
 
            controller: controller
 
        };
 
        function controller($scope, $element) {
 
            var options = $element.data();
 
            options.classInput = $element.data('classinput') || options.classInput;
 
            $element.filestyle(options);
 
        }
 
    }

Angular Controller

Write the attribute ID:

var handleFileSelect = function (evt) {
 
            var file = evt.currentTarget.files[0];
 
            var reader = new FileReader();
 
            reader.onload = function (evt) {
 
                $scope.$apply(function ($scope) {
 
                    $scope.myImage = evt.target.result;
 
                });
 
            };
 
            if (file)
 
                reader.readAsDataURL(file);
 
        };
 
        angular.element(document.querySelector('#fileInput')).on('change', handleFileSelect);

Click the F5 button and run the application. Now it will appear in the browser and you can see the result.

Output 1

Angular

If you click the upload button, it will open file selectable windows and select any image in there.

Output 2

Angular

Once open, the image will be loaded in the image preview. The initial crop area will be represented as “Square.”
