How can you implement alpha compositing?
Alpha compositing is the process of combining an image with a background to create the appearance of partial or full transparency. It is often used to add special effects to images or to make certain elements of an image stand out. There are a few different ways to implement alpha compositing, but one common method is to use a separate alpha channel. This channel stores the transparency information for each pixel in the image. When the image is displayed, the alpha channel is used to composite the image with the background.
