background erase feature of png images in Keynote.
Using the older version of keynote I could upload a png image and erase the background. In addtion I could use the cursor to erase interior portions of image of a particular color. the newest version does not allow for erasing interior colors. am I doing something wrong or is it now impossible to do it in the latest keynote. I see that there are other apps that may provide that feature. If so is there any app which is apple compatible and worth getting?
