Check the amount of data read by the data acquisition procedure (the fifth
parameter to the image statement.  This procedure is called a sufficient
number of times to get the necessary amount of information, but does not
know how much information is needed.  Therefore, the final call to this
procedure may read past the end of the actual data.  In order to avoid
having to pad data at the end of the image data it is necessary that the
total number of bytes required by the image be an exact multiple of the
number of bytes returned by the procedure.
