Save Remote ImageView from ScrollableView to the Photo Gallery

Hey guys, does anyone know how to save a remote ImageView from a ScrollableView to the Photo Gallery? I was thinking I would have to use xhr, but it seems that there should be an easier way, since the image is already loaded in an ImageView.

  • Accepted Answer

    var f = Titanium.UI.ImageView.toBlob('+scrollView.currentPage+');

    Should be

    var f = view13.toBlob('+scrollView.currentPage+');

    • I was able to get it working with this:

      var f = view13.toImage();
Titanium.Media.saveToPhotoGallery(f);

    • Hi guys,

      I tested toBlob and toImage(). If i use toBlob() i only get the image. If i use toImage() i get the view. And the transparency is white.

      So i use the toBlob();

  • try this

    Titanium.UI.ImageView.toBlob

    the once you get the blob, save to gallery

    Titanium.Media.saveToPhotoGallery

    • This is what I have so far for the ImageView that is used in the scrollableView:

      var view13 = Ti.UI.createImageView({
    image:'http://www.example.com/files/photo/001.jpg',
    height:1024,
});

      This is what I have for saving the file to the Photo Gallery:

      savedialog.addEventListener('click', function(e) {
if (e.index == 0) {
var f = Titanium.UI.ImageView.toBlob('+scrollView.currentPage+');
Titanium.Media.saveToPhotoGallery(f);

      I still can't seem to get it to function properly. I'm not getting any errors except for the console telling me: message = "Result of expression 'Titanium.UI.ImageView' [undefined] is not an object.";

      You were correct about converting the ImageView to a Blob. Thank you for your help. I really appreciate it.
