<p><i>raw2tiff</i> converts a raw byte sequence into

image is created with data samples packed
(<i>PlanarConfiguration</i>=1), compressed with the PackBits
algorithm (<i>Compression</i>=32773), and with each strip no
more than 8 kilobytes. These characteristics can overridden,

<p><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>
<!-- INDENTATION -->
<p>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>
