As of Version 6.0, RasterArray has been superseded by new capabilities in Raster.
RasterArray[{{g11, g12, ...}, ...}] is a two-dimensional graphics primitive which represents a rectangular array of cells colored according to the graphics directives gij.
If array has dimensions {m, n}, then RasterArray[array] is assumed to occupy the rectangle Rectangle[{0, 0}, {m, n}].
RasterArray[array, {{xmin, ymin}, {xmax, ymax}}] specifies that the raster should be taken instead to fill the rectangle Rectangle[{xmin, ymin}, {xmax, ymax}].
Scaled and Offset can be used to specify the coordinates for the rectangle.
