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