A raster dataset. A raster consists of one or more bands, or sets of values, which are most commonly associated with colors when the raster represents an image. For instance, a typical color image contains three sets of values, or bands (red, green, and blue) which define the color of pixels within the image. The following raster image formats can be read by the raster class: BMP, ECW, IMG, JP2, NTF, NITF, PNG, SID, TIF, TIFF, JPG, JPEG, PPM, PGM, CLDS, and TGA. To create a texture from a raster, pass it to the From Raster method.
