Add Alpha Channel: An alpha channel is automatically added into the Channel Dialog as soon as you add a second layer to your image. If the image has only one layer, it is considered as a background layer and has no Alpha channel. This background layer without Alpha channel cannot have transparency or a layer mask. In this case, you can Add an Alpha channel with this command.

#### 10.40.1. Activating the Command

- You can access this command from the image menubar through Layer → Transparency → Add alpha Channel.
