Implicit Images in FITS?

[Wayne Landsman]

Is anyone aware of any proposals to allow "implicit images" in FITS? 
For example, to store an image of constant intensity, one could specify
the size of the image and the constant value in the header.   This
information is sufficient to reconstruct the image, so that the explicit
data portion of the FITS file need not be specified.
