Angularjs Compress Image Before Upload

Angularjs Compress Image Before Upload



Angularjs Compress Image
Angularjs Compress Image

Angularjs  Uploading the image compressed method. AnguarJs Image Crop Click Here  Here Code But This method is very slow loading. try this

View.html

<div>
    <div class="rating-camera-icon">
        <input type="file" accept="image/*" name="file" ng-file-
         select="onFileSelect($files)">
    </div>
    <img ng-show="fileName" ng-src="server/{{fileName}}" width="40"
     style="margin-left:10px">
</div>


Controller.js

$scope.onFileSelect = function($files) {
        for (var i = 0; i < $files.length; i++) {
            var file = $files[i];
            if (!file.type.match(/image.*/)) {
                // this file is not an image.
            };
            $scope.upload = $upload.upload({
                url: BASE_URL + 'upload.php',
                data: {myObj: $scope.myModelObj},
                file: file
            }).progress(function(evt) {
                    // console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
                    // $scope.fileProgress = evt.loaded / evt.total * 100.0;
                }).success(function(data, status, headers, config) {
                    // file is uploaded successfully
                    $scope.fileName = data;
                });
        }
    };


Angularjs Image Compress is very slow load so another method is  Angularjs  Resize Image and Uploading.

// from an input element
var filesToUpload = input.files;
var file = filesToUpload[0];

var img = document.createElement("img");
var reader = new FileReader();  
reader.onload = function(e) {img.src = e.target.result}
reader.readAsDataURL(file);

var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0);

var MAX_WIDTH = 800;
var MAX_HEIGHT = 600;
var width = img.width;
var height = img.height;

if (width > height) {
  if (width > MAX_WIDTH) {
    height *= MAX_WIDTH / width;
    width = MAX_WIDTH;
  }
} else {
  if (height > MAX_HEIGHT) {
    width *= MAX_HEIGHT / height;
    height = MAX_HEIGHT;
  }
}
canvas.width = width;
canvas.height = height;
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0, width, height);

var dataurl = canvas.toDataURL("image/png");

Angularjs Image Crop

Style.css

.cropImage {
  background: #E4E4E4;
  overflow: hidden;
  width:500px;
  height:350px;
}


View.html

<body ng-app="app" ng-controller="Ctrl">
  <div>Select an image file: <input type="file" id="fileInput" /></div>
  <div class="cropImage">
    <img-crop image="myImage" result-image="myCroppedImage"></img-crop>
  </div>
  <div>Cropped Image:</div>
  <div><img ng-src="{{myCroppedImage}}" /></div>
</body>


Controller.js

angular.module('app', ['ngImgCrop'])
  .controller('Ctrl', function($scope) {
    $scope.myImage='';
    $scope.myCroppedImage='';

    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;
        });
      };
      reader.readAsDataURL(file);
    };
    angular.element(document.querySelector('#fileInput')).on('change',handleFileSelect);
  });
