13       Minimum unique abbreviation of option is acceptable.  You may use  dou‐
14       ble  hyphens  instead  of single hyphen to denote options.  You may use
15       white space in place of the equals sign to separate an option name from

DESCRIPTION

21       This program is part of Netpbm(1).
22
23       pngtopnm  was  obsoleted  by  pngtopam(1), introduced with Netpbm 10.44
24       (September 2008).  pngtopam is backward compatible with pngtopnm,  plus
25       adds  many additional functions, including the ability to produce a PAM
26       image that includes a transparency (alpha) channel.
27
28       Starting in Release 10.48, pngtopnm is just an alias for pngtopam.
29
30       pngtopnm remained in the Netpbm package through Release  10.47  because
31       it  may  have  fewer  bugs  than pngtopam in those releases, and may be
32       faster in some environments.  But pngtopnm's incompatibility  with  the
33       most  current PNG libraries makes it impractical to maintain along with
34       pngtopam now.
35
36       In releases before 10.48, you can use the  pngtopam  documentation  for
37       pngtopnm, considering the following differences:

41
42       ·      pngtopnm  options  are  a  subset  of  pngtopam's, as documented
43              above.
44
45
46       ·      Any change that the pngtopam manual says happened  in  or  after
47              Netpbm 10.44 doesn't apply to pngtopnm.
