You know how Keynote has that "Instant Alpha" tool that deletes a certain color portion of an image and makes it transparent? For example, an image of a flower with a white background is inserted into Keynote and, in order to make the presentation more professional-looking, the Instant Alpha tool is used to get rid of the white background, making just the flower show on the slide. Is there a tool in PowerPoint that does the same thing? I'm new to PowerPoint.
