hdifftopam — convert horizontal difference image to original PAM image


hdifftopam[pamfile] [-pnm] [-verbose]

Minimum unique abbreviation of option is acceptable.  You may use double hyphens instead of single hyphen to denote options.  You may use white space in place of the equals sign to separate an option name from its value.


This program is part of Netpbm(1).

hdifftopam undoes what pamtohdiff does.



    This option tells hdifftopam to create a PNM image (i.e. PGM or
    PPM).  Without it, hdifftopam creates a PAM image (with a
    tuple type of "unhdiff").  If the PAM does not have the proper depth
    to be a PGM or PPM (i.e. 1 or 3) and you specify -pnm,
    hdifftopam fails.
