       pngtopnm - convert a PNG image into a PNM image

       pngtopnm [-verbose] [-alpha | -mix] [-background=color] [-gamma=value] [-text=filename] [-time] [pngfile]

       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).

       pngtopnm was obsoleted by pngtopam(1),introducedwithNetpbm10.44 (September 2008).  pngtopam is backward compat-
       ible with pngtopnm, plus adds many additional functions, including the ability to  produce  a  PAM  image  that
       includes an alpha (transparency) channel.

       Starting in Release 10.48, pngtopnm is just an alias for pngtopam.

       pngtopnm  remained  in the Netpbm package through Release 10.47 because it may have fewer bugs than pngtopam in
       those releases, and may be faster in some environments.  But pngtopnm's incompatibility with the  most  current
       PNG libraries makes it impractical to maintain along with pngtopam now.

       In  releases  before 10.48, you can use the pngtopam documentation for pngtopnm, considering the following dif-

       ?      pngtopnm options are a subset of pngtopam's, as documented above.

       ?      Any change that the pngtopam manual says happened in or after Netpbm 10.44 doesn't apply to pngtopnm.
