With this utility you can wrap your interferogram to arbitrary interval instead of [-pi, pi). Can be used for example to make fringes correspond to, e.g., 1 cm displacement.

 PROGRAM: wrap wraps float binary file to interval [a,b)

 USAGE: wrap infile [a b [ofile]]

 EXAMPLE: wrap interferogram.raw -4pi 4pi interf4.raw

 default \outputfile    == infile.wrap
 default interval [a b) == [-pi pi)
