How to use the Background layer

The Background layer is at the bottom of the Layer Editor. When hidden (tap Hiding a layer group icon to hide it), this creates an alpha channel. The Background layer can also be used to change the background color of your image.

Why create an alpha channel?

Making your background transparent in SketchBookIt’s handy when compositing (combining) an assortment of images. The alpha channel will enable the background of one image to show through the alpha channel of the other images. This is because the alpha channel doesn’t contain any pixels. SketchBook will display a grey and white checked pattern to indicate an alpha channel.For how to create an alpha channel, see How to create an alpha channel.
