Not sure if this is a valid use case but assigning it to engineering team for evaluation.

Long term solution: Expose a method to rotate them directly. Perhaps as an external graphics module. Short term solution: Because of how computer graphics work, the transform is not applied until after the view is rendered. That is, an imageView's transform will NOT appear within its own toImage, but only in toImages of parent views. Thus, the following code DOES work:

   /********  capture image in a imageView  ********/
   var wrapperView = Ti.UI.createView();
   var imageView = Ti.UI.createImageView({  
         width:win.width,
         height:win.height,
         image:event.media
   });
   wrapperView.add(imageView);
   win.add(wrapperView);
       
   /******** rotate the imageView ************/
   var transformCurrentPicture = Titanium.UI.create2DMatrix();
     imageView.addEventListener('click',function(e){
         transformCurrentPicture = transformCurrentPicture.rotate(90);
         imageView.transform=transformCurrentPicture;
         savePhoto('Hello.png',wrapperView.toImage());   
   });

Moving this be marked invalid, and, if so desired, a module feature request for image manipulations.
