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.

InitializeWithRaster	Initializes a raster from another raster.
InitializeWithStringUri	Initializes a raster from a Uri, which can be a file, HTTP, HTTPS, or FTP source. See Raster for a list of supported formats.
InitializeWithStringUriXYWidthAndHeight	Initializes a raster from a Uri. Only the specified subsection of the raster is read. See Raster for a list of supported formats.
