</h1>
  <div class="markdown level0 summary"><p>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'.</p>
