Question

I need one help.I am using Angular.js( ie-ngFileUpload ) to upload image .Here i need to crop that image according to the required height and width.I am explaining my code below.

<input type="file" class="filestyle form-control" data-size="lg" name="uploadme" id="bannerimage"  ng-model="file" ngf-pattern="'image/*'" accept="image/*" ngf-max-size="20MB" ngf-min-height="100" ngf-resize="{width: 100, height: 100}"  custom-on-change="uploadFile" required="required" ngf-select="onFileSelect($file);">

The controller side code for this is given below.

$scope.onFileSelect = function($files) {
 console.log('file details',$files);
 fileURL=$files;
}

In normal upload i am getting the following console message of image format.

$ngfName: "ADMIN_CATETYPE_IMG_PATHorig_iceproductgrooming2.png"
name: "ADMIN_CATETYPE_IMG_PATHorig_iceproductgrooming2.png"
