Gets a pixel block from an image at a given raster ID and at block/tile location (tx, ty). A raster ID (RID) is the object ID of the catalog item containing the image.
The returned binary pixel block data is of the same format as that returned from GetImage().
The pixel block is positioned using block/tile column and row numbers based on a tiling scheme, i.e. the tile origin, the pixel size, and tile size. The tiling information on an image can be obtained using GetRasterInfo method.
