Description

ImageView.toImage() is supposed to return a TiBlob according to the doc, but it returns a KrollDict, where the blob is in the media key. This is implemented in the TiUIView superclass, which calls TiUIHelper.viewToImage. TiUIImageView should override toImage and return a TiBlob, or you can just change the documentation...

Moving this ticket to engineering as I verified that Ti.UI.ImageView does not implement toImage method but inherits it.

In a native module I tried:

   KrollDict imageBlob = TiUIHelper.viewToImage(proxy.getProperties(), myScrollView.getOuterView());
   Object data = imageBlob.get("media");
   byte[] byteArray =  (byte[])data;  // this creashes (cannot cast blob to byte array)
   Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

How can I use a toImage() for BitmapFactory?
