513<p><i>raw2tiff</i> can guess image width and height in case
514one or both of these parameters are not specified. If you
515omit one of those parameters, the complementary one will be
516calculated based on the file size (taking into account
517header size, number of bands and data type). If you omit
518both parameters, the statistical approach will be used.
519Utility will compute correlation coefficient between two
520lines at the image center using several appropriate line
521sizes and the highest absolute value of the coefficient will
522indicate the right line size. That is why you should be
523cautious with the very large images, because guessing
524process may take a while (depending on your system
525performance). Of course, the utility can&rsquo;t guess the
526header size, number of bands and data type, so it should be
527specified manually. If you don&rsquo;t know anything about
528your image, just try with the several combinations of those
529options.</p>
