Scale an image with create2DMatrix().scale, without using a view?

I'd like to resize the image I get from the camera before saving/displaying/uploading it. I'm able to resize it by putting it into a view, but if I understand correctly I should also be able to use create2DMatrix().scale()?

My code looks like:

function scale_image(image, ratio) {
    var scale = Titanium.UI.create2DMatrix().scale(ratio);

The image.transform part fails. I know I can create a view and specify the transform on that view, but I'd like to scale the image first without putting it into a view. Is that possible? How do I use transform on an image?

  • Try this:

    image.transform = scale;

    • That doesn't appear to do anything. I can set the transform, but there's no evidence it's actually resizing the image.

    • I seem to be having the same issue. Any updates on this? :)
