cordova-imagePicker

Cordova Plugin For Multiple Image Selection - implemented for iOS and Android 4.0 and above.

Installing the plugin

The plugin conforms to the Cordova plugin specification, it can be installed using the Cordova / Phonegap command line interface.

cordova plugin add ltc-cdvp-imagepicker --variable PHOTO_LIBRARY_USAGE_DESCRIPTION="Need photo library access to get pictures from there."

Using the plugin

The plugin creates the object window.imagePicker with the method getPictures(success, fail, options)

Example - Get Full Size Images (all default options):

window.imagePicker.getPictures(
    function(results) {
        for (var i = 0; i < results.length; i++) {
            console.log('Image URI: ' + results[i]);
        }
    }, function (error) {
        console.log('Error: ' + error);
    }
);

Example - Get at most 10 images scaled to width of 800:

window.imagePicker.getPictures(
    function(results) {
        for (var i = 0; i < results.length; i++) {
            console.log('Image URI: ' + results[i]);
        }
    }, function (error) {
        console.log('Error: ' + error);
    }, {
        maximumImagesCount: 10,
        width: 800
    }
);

Options

options = {
    // Android only. Max images to be selected, defaults to 15. If this is set to 1, upon
    // selection of a single image, the plugin will return it.
    maximumImagesCount: int,
    
    // max width and height to allow the images to be.  Will keep aspect
    // ratio no matter what.  So if both are 800, the returned image
    // will be at most 800 pixels wide and 800 pixels tall.  If the width is
    // 800 and height 0 the image will be 800 pixels wide if the source
    // is at least that wide.
    width: int,
    height: int,
    
    // quality of resized image, defaults to 100
    quality: int (0-100),

    // output type, defaults to FILE_URIs.
    // available options are 
    // window.imagePicker.OutputType.FILE_URI (0) or 
    // window.imagePicker.OutputType.BASE64_STRING (1)
    outputType: int
};

Note for Android Use

When outputType is FILE_URI the plugin returns images that are stored in a temporary directory. These images will often not be deleted automatically though. The files should be moved or deleted after you get their filepaths in javascript. If Base64 Strings are being returned, there is nothing to clean up.

Android 6 (M) Permissions

On Android 6 you need to request permission to read external storage at runtime when targeting API level 23+. Even if the uses-permission tags for the Calendar are present in AndroidManifest.xml.

Note that the hasReadPermission function will return true when:

• You're running this on iOS, or
• You're targeting an API level lower than 23, or
• You're using Android < 6, or
• You've already granted permission.

  function hasReadPermission() {
    window.imagePicker.hasReadPermission(
      function(result) {
        // if this is 'false' you probably want to call 'requestReadPermission' now
        alert(result);
      }
    )
  }

  function requestReadPermission() {
    // no callbacks required as this opens a popup which returns async
    window.imagePicker.requestReadPermission();
  }

Note that backward compatibility was added by checking for read permission automatically when getPictures is called. If permission is needed the plugin will now show the permission request popup. The user will then need to allow access and invoke the same method again after doing so.
