  Try this, it seems to work…

  Titanium.Media.openPhotoGallery({
      success:function(event) {
          var image = event.media;
  
          Ti.API.info(image.height +' x '+ image.width);
  
          var imageView = Titanium.UI.createImageView({
              image:image,
              width:480,
              height:640
          });
  
          image = imageView.toImage();
          Ti.API.info(image.height + " x " + image.width);
  
  }});
  

• You can use Appcelerator's free ImageFactory module from the market place:

• I'm using e.media.imageAsResized(e.media.width / 2, e.media.height / 2); to cut the image height/width in half. Worth a shot

• Check out this one

  // testend on iOS
  
  var win = Ti.UI.createWindow();
  
  
  win.open();
  
  // the desired image widths
  var imageSizes = [1200,800,600,200];
  
  // open the photo gallery
  Titanium.Media.openPhotoGallery({
  
  // if success:
      success:function(event){
          // this is the image chosen
          var myImage = event.media;
          if(event.mediaType == Ti.Media.MEDIA_TYPE_PHOTO){
              // let's loop through that array
              for(var i = 0; i < imageSizes.length; i++){
                  // create a new file
                  var file = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, 'image'+i+'.png');
                  // get the width from the array
                  var newWidth = imageSizes[i];
                  // write the file as toImage()
                  file.write(
                      Ti.UI.createImageView({
                          image:myImage, //file name
                          width:newWidth, // file new width
                          height:(newWidth/myImage.width)*myImage.height // some math to get the height
                      }).toImage()
                  );    
                  // done, loop again
              }        
          } else {
  
          }
      },
      cancel:function(){
  
      },
      error:function(error){
      },
      mediaTypes:[Ti.Media.MEDIA_TYPE_PHOTO]
  });
  

• Hi,

  Javascript ist capable of resizing images, even in a content aware fashion:
  http://labs.pimsworld.org/wp-content/uploads/2009/04/demo-content-aware-image-resizing-2/

  Search for javascript, canvas, resize on your favorite search engine :)

• This only works if you're working directly with a captured image.

  I was looking for a generic resize and crop of images once loaded into an image view, but no such luck – at least not on android. There is an undocumented function that does help ios only and I updated another post with some android module code.

• yes, there are actually more than one way to do this.
  http://docs.appcelerator.com/titanium/latest/#!/api/Titanium.Blob-method-imageAsResized

  imageAsResized, imageAsCropped,imageAsThumbnail

  var blob = f.read();
  photo = blob.imageAsResized(blob.width / 4, blob.height / 4);
