This interface defines methods to access image attributes (width, height, number of components, etc.). The image can be tiled or not (i.e. if the image is not tiled then there is only 1 tile). It should be implemented by all classes that provide image data, such as image file readers, color transforms, wavelet transforms, etc. This interface, however, does not define methods to transfer image data (i.e. pixel data), that is defined by other interfaces, such as 'BlkImgDataSrc'.
