Raster layers
Raster layers are layers that contain raster data. Raster data is composed of individual elements, called pixels, arranged in a grid. Each pixel has a specific location and color. Photographic images are composed of raster data. You can copy an image or part of an image to the clipboard and paste it as a new layer. The effects commands, the painting tools, and many other tools apply only to raster layers.
