Also known as objects in some software programs. These are really useful when building up an image. Each layer is like a sheet of plastic or glass that can be laid on top of each other. Areas that have pixels block pixels from the layers below and areas that are clear let the pixels show through from lower layers. Layers are used to create complex collages and add repositionable text and graphics. More advanced programs have Layer blend modes that allow pixels on one layer to react with ones on layers below.
Images edited in Adobe Photoshop, Paint Shop Pro and similar image-processing applications may be made up of a number of layers, each of which contains part of the image. A layer is one image among a stack of others. When the layers are combined (or stacked together), a single image results.
