The raster layer is a layer type which draws displays a single image. This image may be synthesized as the view changes or may be an image imported from a file, such as a TIFF image. Raster layers will warp their images to match any map projections which is in effect (provided the projection is invertible).
There are a number of special-purpose raster layers:
If the JAI plugin is installed, image layers can be georeferenced if the image file contains geographic information. At present, a limited subset of GeoTIFF is supported.
