<h2>GUESSING THE IMAGE GEOMETRY
<a name="GUESSING THE IMAGE GEOMETRY"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><i>raw2tiff</i>
can guess image width and height in case one or both of
these parameters are not specified. If you omit one of those
parameters, the complementary one will be calculated based
on the file size (taking into account header size, number of
bands and data type). If you omit both parameters, the
statistical approach will be used. Utility will compute
correlation coefficient between two lines at the image
center using several appropriate line sizes and the highest
absolute value of the coefficient will indicate the right
line size. That is why you should be cautious with the very
large images, because guessing process may take a while
(depending on your system performance). Of course, the
utility can’t guess the header size, number of bands
and data type, so it should be specified manually. If you
don’t know anything about your image, just try with
the several combinations of those options.</p>
<p style="margin-left:11%; margin-top: 1em">There is no
magic, it is just a mathematical statistics, so it can be
wrong in some cases. But for most ordinary images guessing
method will work fine.</p>
