About Layers

An image can consist of several overlapping layers. The empty parts of a layer are transparent which makes the underlying layers visible. Each layer can have its own size and can be shifted with respect to the other layers. A level of transparency can be set for each layer. Layers can be reordered by a user. A layer can be either bitmapped or textual. Several layers can be selected in a group.

Designing different logical parts of an image on separate layers is a convenient technique because it allows you to edit the whole image by editing separate layers or turning them on/off.
