<h2>DESCRIPTION</h2>

|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><i>raw2tiff</i>
|
|
converts a raw byte sequence into <small>TIFF.</small> By
|
|
default, the <small>TIFF</small> image is created with data
|
|
samples packed (<i>PlanarConfiguration</i>=1), compressed
|
|
with the PackBits algorithm
|
|
(<i>Compression</i>=<i>32773),</i> and with each strip no
|
|
more than 8 kilobytes. These characteristics can overridden,

or explicitly specified with the options described

<h2>GUESSING THE IMAGE GEOMETRY</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>
