Class RasterImage

java.lang.Object
  android.image.Image
      android.image.RasterImage

Direct Known Subclasses:

FromFile

public class RasterImage
extends Image

Represents an raster Image drawn into a Buffer. Because rotating and scaling arbitrary shapes/images is difficult, we can rasterize, then apply effects. It also allows us to merge images (i.e., overlays) into a single image to make drawing more efficient.
