<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>

|
<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>
