file_pgm - writes intensity distribution into a pgm file.
write the intensity distributions of a field into a pgm file. Files produced with file_pgm can be imported by a popular X graphical program XV, which saves to many other formats and allows for different conversions. Pgm stays for ''portable graymap'' and can be converted to other formats with netpbm or pbmplus packages. Files produced with file_pgm can also be imported by the Scilab function fil_ter . The gamma parameter for outfiles that are saved for further used has to be set to 1 (as mentioned before, the default is 2).
